Abstract

The invention relates to a pressure-resistant and wear-resistant lubricant, which comprises the following components: 90-95 parts by weight of base oil, 2.0-2.5 parts by weight of polymethacrylate, and 3-3.5 parts by weight of thiophosphorus bis-octyl Basic zinc salt, 1.5-1.8 parts by weight of trihydroxybenzoic acid, 1-1.5 parts by weight of bis-alkenylsuccinimide, 1.2-1.5 parts by weight of phenylalanine, 0.8-1.2 parts by weight of sulfonic acid Calcium, 1.2-2 parts by weight of graphite powder, 2.5-3.0 parts by weight of modified molybdenum disulfide, 1.8-2.0 parts by weight of naphthyl phenyl phosphate and 1.2-1.5 parts by weight of polyvinyl n-propyl ester. In the above technical solution, the performance of the base oil is improved through the synergistic effect of each component, and each component can be uniformly dispersed, so that the lubricating oil has good lubricating performance, especially outstanding wear resistance and high temperature resistance.

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...
