What is molybdenum disulfide ?

Molybdenum disulfide is the main component of molybdenite. Black solid powder with metallic luster. The chemical formula is MoS2, the melting point is 1185℃, the density is 4.80g/cm (14℃), and the Mohs hardness is 1.0-1.5.

Molybdenum disulfide lubrication mechanism

Molybdenum disulfide can be adsorbed on the metal surface (note that the metal is mentioned here, and PTFE is generally used for plastics) to form a lubricating film, which plays a role in lubricating when the lubricant film is broken.

Molybdenum disulfide adheres to the friction pair with the lubricant and forms a stronger connection (chemical affinity or physical embedding) than the lubricant.

Features of molybdenum disulfide

When used in a humid environment, molybdenum disulfide may cause electrochemical corrosion of the metal. In a low-temperature and humid environment, the performance of molybdenum disulfide will be affected.

Graphite can also be used as a solid additive, but compared with graphite, the friction coefficient of molybdenum disulfide is much smaller than graphite, so the frictional resistance caused is smaller. At high temperatures, molybdenum disulfide will oxidize to form molybdenum trioxide, which does not have lubricity.

Under dry, high temperature and vacuum conditions, the performance of molybdenum disulfide can be fully utilized.

In the presence of a high concentration of oxygen, the oxidation rate of molybdenum disulfide increases and becomes molybdenum trioxide. In the air, below 300℃, the oxidation rate of molybdenum disulfide is very slow and its properties are very stable. Above 400 degrees Celsius, molybdenum disulfide slowly begins to oxidize to form molybdenum trioxide. After that, the higher the temperature, the more serious the degree of oxidation and the rate of oxidation, reaching about 600 degrees Celsius, and the rapid oxidation of molybdenum disulfide in the air. In addition to humidity and temperature, particle size also affects the oxidation rate of molybdenum disulfide. Under the same conditions, the finer the powder, the faster the oxidation rate. Although molybdenum trisulfide does not have lubricity, it will not cause obvious wear on the metal friction surface. Therefore, after molybdenum disulfide is partially oxidized to molybdenum trisulfide, it can still maintain a certain degree of lubricating performance.

Molybdenum disulfide begins to decompose at 1370℃, with a melting point of 1700℃.

In environments with high humidity and water contact, molybdenum disulfide can cause metal corrosion. The use of additives can inhibit corrosion to a certain extent. However, if the lubricating surface is subjected to extremely high pressure, the performance of anti-corrosion additives may also fail.

Although molybdenum disulfide itself is a lubricant, it is a solid after all. Adding to the grease will reduce the smoothness of the grease and increase friction to a certain extent. Therefore, for general load equipment, if it is not necessary or specified to require molybdenum disulfide lubricating oil (extreme pressure lubricating oil/grease), it is not recommended to use it. Molybdenum disulfide is suitable for heavy loads and low speeds, resulting in a large amount of boundary lubrication.

What is oil additives?

Oil additives: Compounds used to improve the performance of lubricating oils by adding a small amount of ingredients.

Common oil additives include: detergents and dispersants, antioxidants, anticorrosives, pour point depressants, antifoams, rust inhibitors, viscosity index improvers, etc.

Viscosity index improvers are the leading products of lubricant additives, accounting for approximately 25.2% of the entire market share in 2020.

Reasons for the emergence of Oil additives:

With the continuous development of the machinery industry and the increasingly stringent environmental requirements, the requirements for the performance of lubricants are also getting higher and higher, which forces the production of additives.

In order to improve the performance of lubricants, in addition to further improving the quality of the base oil, the use and improvement of additives are also indispensable.

The role of oil additives:

1. Give lubricants new properties;

2. Strengthen the performance of base oil;

3. Slow down the speed of bad changes in lubricating oil.

Types of oil additives

1. Additives that improve the physical properties of base oils, such as viscosity index improvers, anti-foaming agents, pour point depressants, etc.;

2. Additives to protect the lubricated surface, such as anti-corrosion agent, anti-rust agent, anti-wear agent, detergent and dispersant, etc.;

3. Additives to protect lubricating oil, such as antioxidants.

In order to improve performance, at least one oil additive is added to the current lubricants, and some lubricants contain more than ten kinds of oil additives. Such as detergents, which can be used to solubilize polar substances, neutralize acidic substances in lubricating oils, and make some lubricating oils have antioxidant properties; dispersants can prevent the formation of sludge, keep the engine clean, and correct the accumulation of soot. .

Graphite is a traditional solid lubricating material. Due to its special layered crystal structure, graphite material has good lubricating properties. As early as the 1950s, many graphite lubrication products have been developed one after another. For example, the world-famous Leica camera made in Germany used graphite powder as the lubricating material for mechanical parts. In the 1960s, my country also produced bronze oil-impregnated graphite bearings. In recent years, the domestic "Chikai" brand of energy-saving antifriction king additives and "Medron" series lubricants have also come out. Many studies and practices have shown that graphite used in lubricating oil has huge economic benefits and has many advantages of its own. With the development of science and technology and the deepening of scientific research, graphite lubricating materials have been extended to appear in the form of graphite derivatives, such as flake nano graphite, expanded graphite, fluorinated graphite, and elemental or compound intercalated graphite. This article comprehensively discusses the types, dispersion stability and lubricating effect of graphite lubricant additives, and provides references for the development and application of new graphite lubricant materials.

Influencing factors of graphite lubrication effect

Graphite particle size

The lubrication performance of graphite is affected by the particle size. Some scholars have shown that graphite powder with an average particle size of 4~5μm will produce a good lubricating effect, which can minimize the friction and wear of the specimen. However, more scholars have shown that controlling the average particle size below 0.5 µm is the key to the stable suspension of graphite in lubricating oil and also the condition for exerting lubricating performance. Graphite particles are too large to enter between the friction pairs, and cannot isolate and hinder the contact between the two friction surfaces, thus affecting the lubrication performance. However, it is obvious that if the graphite particles are too small to severely damage the graphite layered crystal structure, the friction reduction mechanism of the graphite sheet slip will also be lost, and the graphite lubrication effect is also poor. Therefore, the proper size of graphite particles is the key to graphite's lubricating effect.

The structure of graphite

The structure of graphite is one of the factors affecting the lubricating effect of graphite. Different graphite structures determine different types of graphite. It has not been reported so far that the lubricating effect of expanded graphite, fluorinated graphite, graphite intercalation compound and flake nano-graphite has been compared. It can be seen that under the condition of proper graphite particle size, different graphite types have their own optimal lubricating environment, which is difficult to compare. For example, expanded graphite has a strong absorption capacity and enrichment effect, and it can be mixed with extreme pressure additives to achieve the best effect; when the F/C ratio of fluorinated graphite reaches 1.0, the wear resistance life reaches the best value; and the temperature determines the graphite intercalation The degree of deintercalation of the compound; some scholars have pointed out that as the graphite diameter-to-thickness ratio increases, the specific wear of the lubricated material decreases significantly. It can be seen that the diameter-to-thickness ratio affects the lubricating effect of flake nano-graphite.

External environment

The particle size and structure of graphite are the internal factors that determine the lubricating effect of graphite, and the external environment is the external cause of the lubricating effect of graphite. As early as the 1940s, Robert proposed that humidity is an important factor affecting the lubrication effect of graphite. Water vapor and other small molecules can adsorb on the crystal edges of graphite and invade along the dissociation surface (interlayer), thereby reducing the surface energy of the graphite layer. It makes it easier for graphite to adsorb and form a film on the friction surface, thereby improving the lubricating effect. Bowden et al. also proposed that the friction coefficient of graphite under vacuum conditions increased significantly. Once air was introduced, the friction coefficient decreased rapidly. Therefore, improving the environmental medium of graphite-based lubricating materials is also the key to more effective graphite lubricity. Graphite and graphite derivatives have been widely used in lubricating oil additives and other lubrication fields due to their own good lubrication advantages. However, it is worth noting that the preparation process of ultra-fine and high-purity graphite still requires technological breakthroughs. Graphite nanoization and high-purity industrial production of graphite without sulfur and chlorine will be the future development trend of graphite; at the same time, with the development of technology, the development of new graphite derivative materials such as hollow nanometer will also provide excellent graphite lubrication The agent provides the material basis. It is believed that new graphite lubricating materials will continue to play a more important role for industrial lubrication.

What are the ingredients of lubricating oil?

Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oils and give some new properties. It is an important part of lubricating oil.

Lubricating oil base oil is mainly divided into three categories: mineral base oil, synthetic base oil and biological base oil. Mineral base oils are widely used and used in a large amount (about 95% or more). However, in some applications, synthetic base oils and bio-oil base oils must be used for blending products, so these two base oils have developed rapidly.

Mineral oil base oil is refined from crude oil. The main production processes of lubricating base oil include: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplement refining.

The chemical composition of mineral base oils includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures. Its composition is generally alkane (straight chain, branched chain, multi-branched chain), cycloalkane (monocyclic, bicyclic, polycyclic), aromatic hydrocarbon (monocyclic aromatic hydrocarbon, polycyclic aromatic hydrocarbon), cycloalkyl aromatic hydrocarbon and oxygen-containing, nitrogen-containing , Sulfur-containing organic compounds and non-hydrocarbon compounds such as gums and asphaltenes. Biological base oil (vegetable oil) is becoming more and more popular, it can be biodegraded and quickly reduce environmental pollution. Synthetic lubricating oil has the characteristics of excellent low temperature performance, good lubrication performance and long service life. It can be suitable for environments such as high load, high speed, high vacuum, high energy radiation and strong oxidizing media. Since all industrial companies in the world are seeking measures to reduce environmental pollution, and this "natural" lubricant has this feature, although the cost of vegetable oil is high, the increased cost is enough to offset the use of other mineral oils and synthetic lubricants Environmental governance costs caused by oil. According to the nature and processing technology of crude oil, it is classified into paraffin base oil, intermediate base oil and naphthenic base oil.

Why do lubricants need additives?

Lubricating oil base oil possesses some basic characteristics and performance of lubricating oil, but only relying on general processing technology to improve lubricating oil cannot produce lubricating oil with various properties that meet the requirements of use. In order to make up for the defects of certain properties of lubricating oil and give lubricating oil some new excellent properties, various additives with different functions are added to the lubricating oil. The addition amount ranges from a few parts per million to tens of percent.

Adding additives to lubricating oil has two main functions: one is to change the physical properties of the lubricating oil, such as viscosity, freezing point, etc.; the other is to increase or enhance the chemical properties of the lubricating oil, such as anti-oxidation and anti-corrosion. The use of additives in lubricating oil not only meets the requirements of various new machinery and engines, but also prolongs the service life of lubricating oil, reducing the demand for lubricating oil in the proportion of petroleum products.

What is lubricating oil additives？

The concept of lubricating oil additives is to add one or several compounds in the lubricant to give the lubricant some new characteristics or improve some of the existing characteristics in the lubricant. Additives are divided into antioxidants, anti-wear agents, friction modifiers, extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and rust inhibitors, flow point improvers, viscosity index improvers, etc. according to their functions. The additives sold in the market are generally composites of the above single additives. The difference is that the composition of the single additive is different and the ratio of several single additives in the composite additive is different.

GrapheneLubricant Oil Additive

Since graphene was invented and won the Nobel Prize in Physics, everyone has put great expectations on the benefits this new material will bring to mankind. In the past two years, global application research on graphene has become more frequent.

In 2016, after years of research and field testing of thousands of cars, graphene oil additive, the research and development result of polycarbon composites, was announced, which attracted widespread attention in the automotive aftermarket. On January 4, 2017, Polycarbon Composites held a global press conference for the product, which attracted a lot of industry leaders to observe.

The oil additive is added to the car engine oil. Through the oil circulation, it can reach each friction surface in the engine cylinder to enhance the machine's anti-wear ability. In addition, the product can also be firmly attached to the metal surface to repair wear grooves and scratches, forming a layer of "graphene protective film" to isolate direct friction between metals. It can keep the engine of a new car after a period of time as new; let the engine of an old car increase power, save energy and reduce consumption, it is simply another technological revolution in the application of graphene.

Through actual experience and scientific and technological testing, thousands of car owners have confirmed that after adding this graphene oil additive, their car has more power, less noise, no shaking of the steering wheel, and the problem of oil burning has been solved. Fuel consumption and car Exhaust emissions, etc. are significantly reduced.

Relevant experts said that the graphene lubricant additives of polycarbon composites overturned people's existing understanding of traditional automobile oil protective agents. While providing car owners with a good car experience and tangible benefits, it will reduce exhaust hazards and improve the current situation of urban smog, which has social significance beyond the product itself.

Molybdenum disulfide as a lubricant

Like most mineral salts, MoS2 has a very high melting point but starts to sublime at a relatively low 450°C. This property is useful for purifying compounds. Due to its layered structure, the hexagonal MoS2 is like graphite and is an excellent dry lubricant. It and its cousin tungsten disulfide can be used as a surface coating in mechanical parts (for example, the aerospace industry), two-stroke engines (the type used in motorcycles), and barrels (to reduce friction between bullets and ammunition) ).

Unlike graphite, the lubricating properties of MoS2 do not depend on adsorbed water or other vapors. Its maximum temperature in an oxidizing environment is 350°C, and its maximum temperature in a non-oxidizing environment is 1100°C. Its stability allows it to be used in high-temperature applications where grease is not practical.

It is understood that molybdenum disulfide powder is recognized as the best solid lubricant in the world, but in the application of lubricating oil, because molybdenum is only soluble in aqua regia and boiling concentrated sulfuric acid, and the physical diameter of molybdenum particles is large, it will form in the oil Sediment layering can not be uniformly integrated with the engine oil, so it can only be added to the grease. This makes the manufacture of molybdenum disulfide lubricants a global problem. At present, only a few companies in Germany and the United States have mastered this technology.

Molybdenum disulfide is the main component of molybdenite—solid black powder with a metallic luster. The chemical formula is MoS2, the melting point is 1185°C, the density is 4.80g/cm (14°C), and the Mohs hardness is 1.0-1.5.

Analysis of the advantages and disadvantages of molybdenum disulfide as a lubricant

(1) Thoroughly prevent oil leakage, clean and clean, which significantly promotes civilized production.

(2) A large amount of grease can be saved.

(3) Improve the technical operating conditions, extend the maintenance cycle, reduce the labor intensity of maintenance workers, and save labor.

(4) Due to the low friction coefficient of molybdenum disulfide, the frictional resistance between the friction devices is small, which can save electricity. According to the measurement of the brother unit, the power can be held by 12%.

(5) It can reduce mechanical wear, extend the service life of friction equipment, reduce the loss of equipment parts, and improve the attendance rate of the equipment.

(6) The application of molybdenum disulfide lubrication solves critical technology and improves work efficiency and accuracy.

(7) Molybdenum disulfide has the functions of filling and filling, which can restore the geometric dimensions of individual parts and extend the service life.

(8) Molybdenum disulfide has the characteristics of moisture-proof, waterproof, alkali-proof, and acid-proof.

(9) The use of molybdenum disulfide plastic or powder smelted molded parts can save many non-ferrous metals.

(10) After using molybdenum disulfide lubrication in some equipment, the complicated oil supply system can be omitted, which significantly simplifies the structure of the equipment, relatively improves the effective area utilization, and will also cause significant reforms.

(11) Molybdenum disulfide also has shortcomings, such as poor thermal conductivity, low friction coefficient, and low permeability (compared to thin oil). These shortcomings are the main obstacles to expand the scope of use further. On the contrary, industrialized countries attach great importance to the research of solid lubricants and have also held international lubrication conferences to exchange relevant information and discuss new technologies.

Molybdenum disulfide as a superconductor

In addition to its lubricity, MoS2 is also a semiconductor. It is also known that when doped with an electrostatic field, it and other semiconductor transition metal chalcogenides become superconductors on its surface.

Until 2018, the mechanism of superconductivity was uncertain when Andrea C.Ferrari of the University of Cambridge (UK) and his colleagues and the Turin Polytechnic Institute (Italy), reported on Duogufei. The surface of the meter is related to the superconducting state in MoS2. The author believes that this Fermi surface topology will serve as a guide for seeking new superconductors.

As long as you have bought motor oil, you will know that motor oil is generally composed of two parts, one is base oil and the other is engine oil additive. What kind of relationship do they have? How do they affect the quality of engine oil? In daily life, we often hear the classification of engine oils: mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil. This classification method is based on the processing technology of the base oil used in the engine oil. In fact, engine oil About 80% is base oil, and about 20% is engine oil additive.

Relative to the types of base oils, you may be unfamiliar with oil additives in lubricants. Although base oils are very important, you should know that good lubricants are not good base oils that can bring 100% superior performance. Engine lubricating oil not only plays a role in lubrication, but also needs to bring cleaning, sealing, and anti-rust effects to the engine. No matter how good the base oil is, it cannot perform all functions in every aspect.

First, let us briefly understand the common engine oil additives:

Detergent

When the engine is operated at high temperature, the phenomenon of paint film (Vanish) and carbon deposit (Carbon) will be produced, which must be removed by the detergent in the engine oil, and its composition is metal salts.

Dispersant

When the engine is operating at low temperature, if it is not driven at high speed for a long time, so-called sludge will be produced. To prevent it from being generated, a dispersant must be added to the oil to evenly disperse the sludge in the oil to prevent the sludge from being deposited in the oil filter. On the valve push rod and piston ring, the lubricating oil path is not smooth and the unlubricated parts are chipped and worn.

Anti-Oxidant

Under the high temperature of the engine, the engine oil is especially easy to cause oxidation reaction with the air. After the engine oil is oxidized, the color will deepen and the viscosity will increase, thus increasing the load on the engine. At the same time, the organic acid generated after oxidation will also corrode the engine parts, so the oil is maintained. Oxidation stability is very important, especially in extremely high temperature turbo engines.

Anti-Rust Additive

In order to prevent the metal parts of the engine from rusting, it is of course necessary to add rust inhibitors. The ingredients of this additive contain a polar radical (Polar Radical), which uses the intermolecular polarity to adsorb on the metal surface to protect the metal from air and moisture. And rust due to salt erosion.

Anti-Corrosion Additive

Same as anti-rust additives, but the former is used to protect ferrous metal (Ferrous Metal) parts and the latter is used to protect non-ferrous metal (Non-Ferrous Metal) and alloy (Alloy) parts from corrosion by sulfur and organic acids .

Viscosity Index Improver

The base oil is limited by the nature of crude oil. Its viscosity index can only be improved to a certain extent by the processing technology, and then it must rely on the viscosity index improver. It is also because of the invention of the viscosity index improver that the oil with multiple viscosity can be produced.

Pour Point Depressnat

Pour point depressant is also called pour point depressant. The so-called pour point is to measure the temperature of a certain oil when it starts to not flow, plus 3℃ is the pour point. There will be more or less wax in the oil. (Although the wax has been removed during the refining of the base oil, it still cannot reach 100%). Once these waxes become crystals and solidify at low temperatures, they will prevent the oil from flowing. In order to make the engine start smoothly in winter, it must Inhibitors are added to reduce the pour point, prevent wax from crystallizing, and adapt to cold weather.

Anti-Wear Additive

The so-called boundary lubrication (Boundary Lubrication) occurs when the engine is under high temperature and high pressure, that is, under the condition of high thermal expansion of the metal active surface, the oil film is squeezed apart, and direct friction between metal and metal is formed. In order to prevent In this case, it is necessary to add anti-wear additives. When the additives come into contact with metals, they chemically react, and a protective film is produced to protect the metals from wear when they are in contact with each other.

Anti-Foaming Agent

When the oil is repeatedly stirred in the engine, foam will naturally occur. Where there is foam, where there is no oil film, the engine will lose its protection. On the other hand, where there is foam, it also means that the contact surface with the air increases. It also accelerates its oxidation, so it is necessary to add a defoamer to avoid foam.

Dye

Function 1: For identification, for example, the automatic transmission fluid (ATF: Automatic Transmission Fluid) of automobiles is dyed red to facilitate identification and maintenance in case of oil leakage;

Function 2: For marketing and advertising, for example, most of the two-stroke engine oils in Japan are dyed light blue or red. In addition to being beautiful, it can be used to advertise that the base oil in the lubricant is highly refined and light in color before it is dyed.

What is the formula ratio of Engine oil additive?

In fact, the formulations of all lubricant additives are relatively the same, but slightly different. The formulation of an engine lubricating oil is obtained through many steps such as research, development, and testing, and it takes several years to obtain. For example, some lubricants are specially formulated for urban congestion and often need to be started and stopped. Our fully synthetic extreme protection pays more attention to comprehensiveness and is more suitable for high-temperature engines with turbochargers.

If I use mineral engine oil, should I add a little engine oil additive, such as adding some detergent or anti-rust additive to achieve the effect of fully synthetic engine oil, isn't it more cost-effective?

This is not the case. What is the difference between mineral engine oil and fully synthetic engine oil in base oil? We do not recommend that you buy the engine oil additive by yourself, because the finished engine oil is sold to consumers after strict bench testing and meets the industry specifications and the specifications of major car manufacturers. The formula is the most optimized formula. Add engine oil by yourself On the contrary, additive will affect the efficacy of Castrol oil, and there is a risk of destroying the original efficacy.
