Problems solved by technology

Although the above-mentioned lubricants can reduce wear and repair better, due to the addition of a large amount of dispersant, it not only makes the configuration complicated, it is difficult to realize industrial production, but also makes the system complicated and the stability deteriorates
Disclosed a kind of nano lubricant additive in CN200710121988, has adopted the mode of compound additive to prepare oil-soluble nano-copper, oil-soluble nano-silicon dioxide, and the oil-soluble additive of other metal alloys, but because nano-copper is easily oxidized, although after Surface modification, there is still the problem of nano metal being oxidized

Abstract

The invention discloses a nano-copper type lubricating oil additive, which mainly comprises oil-soluble reactive nano-copper or the oil-soluble reactive nano-copper and oil-soluble nano titanium dioxide. The nano-copper type lubricating oil additive has high dispersity, high stability and high self-repairability, and simultaneously has the functions of saving oil, resisting and reducing abrasion, reducing noises and the like.

Description

technical field [0001] The invention relates to a nano-copper lubricating oil additive, in particular to design a novel lubricating oil additive containing oil-soluble nano-copper and oil-soluble titanium dioxide. Background technique [0002] Lubricating oil additives are the main components to ensure the quality of lubricating oil. Although the amount of additives in lubricating oil is much less than that of base oil, its importance is no less than that of base oil, or even more than that of base oil. China is the third largest lubricating oil consumer after the United States and Russia, and with the rapid development of my country's modern machinery industry, especially the automobile industry, higher requirements have been put forward for the variety and quality of lubricating oil. The original bond friction agent and anti-wear agent in the oil can no longer meet the performance requirements of modern industry for anti-friction and anti-wear performance of lubricating oil...
