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

A boron nitrogen lubricant composition provided by the present invention is characterized in that it is prepared from dimer acid, triethanolamine, boric acid and polyethylene glycol, wherein the molar ratio of dimer acid and triethanolamine is 0.5 ‑1.5:1 The molar ratio of triethanolamine and boric acid is 2‑3:1; the weight fraction ratio of dimer acid and polyethylene glycol is 100:50‑100. The lubricant composition prepared by the invention is a B-N type extreme pressure antiwear agent and antirust agent, and has good lubricity and water solubility. The present invention also provides a micro-lubricant prepared with a boron-nitrogen lubricant composition, which is characterized in that it also contains components such as ethylhexyl palmitate, triethanolamine lauryl sulfate, castor oil maleate, lanolin alcohol, etc. The micro-quantity lubricant prepared by the invention can meet the lubricating cooling, extreme pressure anti-wear and anti-rust requirements of metal processing; when used with a micro-quantity lubrication device, the amount of lubricant used can be saved by more than 90%, and the effect of energy saving, emission reduction and environmental protection is remarkable.
