Problems solved by technology

[0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators.
[0003] In order to solve these problems, the research on micro-quantity lubrication technology has made some progress recently. The micro-quantity lubrication technology has solved the problems of large amount of lubricant used and serious pollution. Excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, Developing a sulfur-free, chlorine-free microlubricant additive with excellent extreme pressure and antiwear properties is a challenge

Abstract

The invention provides a lubricant composition. The lubricant composition is characterized by comprising chitosan phosphate and an amine salt compound; and chitosan phosphate and the amine salt compound are prepared from chitosan and phosphoric acid, wherein the weight ratio of chitosan to phosphoric acid is (2 to 3) to 1. According to the prepared lubricant composition, since the synthesized chitosan phosphate and amine salt compound are a P-N type extreme pressure antiwear agent, the prepared lubricant composition has an excellent extreme pressure antiwear property and good water solubility,and can all or partially replace a traditional extreme pressure antiwear agent containing chlorine, sulfur and phosphorus to be used in environment-friendly micro-cutting fluid, and a small amount ofenvironment-friendly micro-cutting fluid can meet the lubrication cooling, extreme pressure anti-wear and anti-rust requirements of metal machining. The lubricant composition can save the use amountof the cutting fluid by more than 90%, and has remarkable energy saving and emission reduction and environmental protection effects by being matched with a minimal quantity lubrication device for use.
