Problems solved by technology

[0007] On the other hand, although advanced nano-lubrication can improve the anti-wear and anti-friction performance of lubricating oil, its effectiveness and compatibility in existing lubricant / additive systems still need further research
Triglycerides, lecithin, silane coupling agents (KH550, WD20, etc.), stearyl alcohol, PVP, etc. are not commonly used lubricating oil additives. If they are added to gear oils and engine oils, although their anti-wear and friction-reducing properties may However, there are compatibility problems with the original additive system in the finished oil, which affects its anti-wear, anti-friction, anti-oxidation, anti-saponification, detergency and other properties. The author did not study; and tested the anti-oxidation, anti- Saponification, detergency and other performance tests are more complicated and costly
Oil developers as well as consumers remain concerned about the effectiveness of nanolubricants, directly limiting the industrial use of these surfactant-modified nanoparticles

Abstract

The invention discloses a method for obtaining lubricating oil containing lubrication-friendly MoS2 nano-particles.
