Abstract

The invention relates to a compression-resistant wear-resistant lubricant. The compression-resistant wear-resistant lubricant comprises, by weight, 90-95 parts of base oil, 2.0-2.5 parts of polymethacrylate, 3-3.5 parts of a base zinc salt of dioctyl thiophosphate, 1.5-1.8 parts of trihydroxybenzoic acid, 1-1.5 parts of dialkenyl succinimide, 1.2-1.5 parts of phenylalanine, 0.8-1.2 parts of calcium sulfonate, 1.2-2 parts of graphite powder, 2.5-3.0 parts of modified molybdenum disulfide, 1.8-2.0 parts of naphthylphenylphosphate and 1.2-1.5 parts of polyvinyl n-propyl ester. Through synergism of components, base oil performances are improved. All the components can be uniformly dispersed so that lubricating oil lubrication performances are good and wear resistance and high temperature resistance are outstanding.

Description

Technical field [0001] The invention relates to the field of mechanical lubrication, in particular to a pressure-resistant and wear-resistant lubricant. Background technique [0002] Nano-molybdenum disulfide has a layered structure, the sliding between layers is very easy, and the S atom in molybdenum disulfide has a strong affinity for the metal surface, which can form a firm lubricating film on the metal surface, thereby significantly reducing friction and wear. However, nano-molybdenum disulfide has problems such as easy agglomeration and difficulty in dispersion in lubricants, which affect the application of nano-molybdenum disulfide in lubricants. In addition, with the development of large-scale machinery, the requirements for high temperature, pressure and wear resistance of lubricating oil have become higher and higher. Therefore, it is necessary to provide a lubricant with uniform dispersion of nano-molybdenum disulfide, high temperature resistance, pressure resistance ...
