Abstract

The invention relates to a compression-resistant and wear-resistant lubricating agent comprising the following components in parts by weight: 90-95 parts of base oil, 2.0-2.5 parts of polymethacrylate, 3-3.5 parts of 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 naphthylphenyl phosphate and 1.2-1.5 parts of polyvinyl n-propyl ester. According to the technical scheme, all the components take a synergistic effect, so that the performance of the base oil is improved; and all the components can be uniformly dispersed, so that the lubricating property of the lubricating oil is good, and particularly the wear resistance and high-temperature resistance are remarkable.

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, and the sliding between layers is very easy, and the S atoms in molybdenum disulfide have 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, there are problems such as easy agglomeration and difficult dispersion of nano-molybdenum disulfide in lubricants, which affect the application of nano-molybdenum disulfide in lubricants. In addition, with the development of large-scale machinery, the performance requirements of lubricating oil for high temperature resistance, pressure resistance and wear resistance are also getting higher and higher. Therefore, it is necessary to provide a lubricant that can uniformly disperse nano molybdenum disu...
