Abstract

The invention discloses a high-dispersion modified nanometer molybdenum disulfide lubricant and a preparation method thereof. The dispersity of the prepared modified nanometer molybdenum disulfide inthe lubricant is good, the prepared modified nanometer molybdenum disulfide is not easy to agglomerate and stable in property, and the obtained lubricant has relatively high maximum non-seizure load,the grinding spot diameter is small, the friction coefficient is low, and the anti-compression and anti-wear performance is excellent. After the nano molybdenum disulfide is pretreated, the internal structure of the nano molybdenum disulfide is loose and dispersed, and the dispersity is improved and the stability of the nano-molybdenum disulfide in the lubricant is enhanced; and the surface of thenano-molybdenum disulfide is wrapped by using zirconium dioxide; on one hand, the nano-molybdenum disulfide is collaborative with the zirconium dioxide, so that the friction coefficient of the lubricant is reduced, the compression resistance and wear resistance are enhanced, and on the other hand, the dispersity of molybdenum disulfide and its own in a lubricant is also promoted, and the agglomeration phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of lubricants, in particular to a highly dispersed modified nano molybdenum disulfide lubricant and a preparation method thereof. Background technique [0002] Lubricant is an essential substance in the mechanical field, mainly to reduce friction, improve the operating speed of the machine and prolong the life of the machine. With the increasing demand for lubricants in the industry, there are more and more types of lubricants. When people choose lubricants, they generally have to consider the coefficient of friction, material, surface roughness, working environment and working conditions, and the performance of lubricants. Performance and other factors, in mechanical equipment, lubricants are mostly delivered to the parts that need to be lubricated through the lubrication system. Nano-nano molybdenum disulfide has a layered structure, and the sliding between layers is very easy, which can significantly red...
