Abstract

An anti-extreme-pressure lubricant for an internal combustion engine is prepared from the following raw materials in parts by weight: 6-11 parts of trimethyl citrate, 2-6 parts of sodium dodecyl benzene sulfonate, 7-9 parts of trimethyloctane, 2-5 parts of molybdenum disulfide, 3-8 parts of calcium alkyl benzene sulfonate, 4-10 parts of sodium borate, 15-23 parts of base oil, 1-4 parts of epoxy novolac, 2-6 parts of oxalic acid, 1-3 parts of magnesium sulfonate, 4-10 parts of propylene glycol monomethyl ether acetate, 2-6 parts of zinc octoate, 7-10 parts of dipentaerythritol and 2-4 parts of sodium chloride. The anti-extreme-pressure lubricant has the benefits that the extreme pressure resistance is excellent, the cleaning property is achieved, impurities in the internal combustion engine can be washed away, and a favorable lubrication effect can be taken.

Description

technical field [0001] The invention relates to an internal combustion engine lubricating oil against extreme pressure. Background technique [0002] Lubricating oil for internal combustion engines is mainly used in the motor vehicle industry. The lubricating oil for internal combustion engines can form a lubricating film between the two friction surfaces, and the dry friction becomes the friction between lubricating oil molecules, so as to reduce the friction of moving parts and reduce wear. It has good oiliness and is widely used in friction reduction, rust prevention and cooling of friction parts of various gasoline engines and diesel engines. At the same time, it also has the functions of sealing, cleaning and lubricating surface impurities. However, the existing lubricating oil has poor cleaning performance and insufficient extreme pressure resistance, which reduces the service life of the lubricating oil. Contents of the invention [0003] Aiming at the deficiencies...
