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 prepared from, by weight, 100 parts of ricinoleic acid, 50-100 parts of polyethylene glycol, 8-10 parts of isopropanolamine, 5-8 parts of boric acid and 5-8 parts of phosphorus pentoxide. The lubricant composition prepared in the invention is a B-P-N type friction modifier and an antirust agent, and is also a good surfactant. The invention also provides a minimal quantity lubricant prepared from the lubricant composition. The minimal quantity lubricant is characterized by also containing diisodecyl adipate, polysucrose fatty acid ester, castor oil sodium sulfonate, deionized water and other components. The minimal quantity lubricant prepared in the invention can meet the requirements of lubrication cooling, extreme pressure wear resistance and rust prevention in metal processing; and the usage amount of the lubricant can be saved by 90% or more when the lubricant is matched with a minimal quantity lubricationdevice.
