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, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the problems of large amount of lubricant used and serious pollution, but excessive use of sulfur and chlorine-containing additives that are not friendly to the environment , will have a certain impact on the environment
At the same time, when processing difficult-to-machine metals, it is often difficult to achieve the desired effect with minimal lubrication

Abstract

The invention provides an antiwear lubricant composition which is characterized by being prepared from nitrilotriacetic acid, fatty alcohol, polyethylene glycol and phosphotungstic acid, and the molarratio of nitrilotriacetic acid to fatty alcohol is 1 : 2-2.5; wherein the weight ratio of the fatty alcohol to the polyethylene glycol is 100 : 30-50; the weight of the phosphotungstic acid accountsfor 1-2% of the total weight of the nitrilotriacetic acid, the fatty alcohol and the polyethylene glycol. The anti-wear lubricant composition prepared by the invention is a PWN-containing extreme pressure anti-wear additive, has excellent anti-friction performance, and is also a good nonionic surfactant. The trace lubricant containing the anti-wear lubricant composition is prepared from the following components in percentage by weight: 30-40% of the anti-wear lubricant composition; 30-40% of 2,5-furandicarboxylic acid dialiphatic alcohol ester; 5-10% of sodium lauroyl sarcosine; 5-10% of fattyalcohol-polyoxyethylene ether; and the balance deionized water.
