Problems solved by technology

[0004] In recent years, with the increasing requirements for energy saving, emission reduction, environmental protection, and emissions, the research on anti-wear and friction-reducing agent components in lubricating materials has also been continuously strengthened, and there are more and more commercially available products. There are still many problems in the research on the mechanism of action, use characteristics and application fields of friction agents. The existing anti-wear and friction-reducing agent compositions or formulations tend to study the anti-wear effect and friction-reducing characteristics, and attention is paid to long-term anti-wear and friction-reducing agents. Few, and no such patent reports
At the same time, the existing technology has the following problems: (1) The lubricant with organic molybdenum additives as the main friction reducer will cause the friction coefficient to increase after a period of use due to the rapid decomposition of organic molybdenum during use, and the friction reduction effect will change. Poor; and the acidic substances in the decomposition products of organic molybdenum will promote the deterioration of the lubricant; (2) The anti-wear performance of the anti-friction composition mainly composed of organic molybdenum and organic esters is average, and it cannot function at low temperatures. Under these conditions, due to the decomposition of organic molybdenum and the desorption of organic esters, the friction reduction effect becomes worse; (3) The anti-wear and friction reducers mainly composed of organic molybdenum, organic carboxylic acid, and carbamate have serious corrosion problems. The increase of sulfur-containing compounds produced after the product is oxidized leads to a rapid increase in the acidic substances of the lubricant and thus fails

The invention discloses a long-acting anti-wear and friction-reducing agent composition, lubricating grease and processing oil, wherein the long-acting anti-wear and friction-reducing agent composition comprises the following components in parts by mass: 40 to 60 parts of an organic molybdenum compound, 10 to 20 parts of a thiocarbamate compound, 1 to 5 parts of a thiadiazole compound, 1 to 5 parts of a mercaptobenzothiazole compound, 10 to 15 parts of a phosphite ester compound and 10 to 20 parts of sulfide. The long-acting anti-wear and friction-reducing agent composition is good in anti-wear performance, high in friction-reducing performance and low in corrosivity, can remarkably improve the anti-wear and friction-reducing performance of lubricating grease and processing oil as an additive of the lubricating grease and the processing oil, and improves the long-acting performance.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a long-acting antiwear and friction reducing agent composition, lubricating grease and processing oil. Background technique [0002] According to the "stribeck" theoretical curve, the lubrication mode between two friction pairs is divided into three states: boundary lubrication, mixed lubrication and fluid lubrication. Anti-wear additives or anti-friction additives mainly work in the state of boundary lubrication. In the boundary lubrication state, when the friction surface bears a certain load, if the additive can be adsorbed on the metal surface or chemically react with the metal surface, this additive is called an anti-wear additive. When the additive can be adsorbed on the friction surface, or It is also called anti-friction additive to reduce the friction force between friction pairs after the reaction is formed into a film. The additive with both functions is called anti-w...
