Abstract

A lubricant composition provided by the present invention is characterized in that it is prepared from ricinoleic acid, rare earth oxide, boric acid, phosphoric acid, and diethylaminoethanol, and the ratio of parts by weight of the components is: ricinoleic acid 100; rare earth oxide 8‑10; boric acid 5‑8; phosphoric acid 3‑5; diethylaminoethanol 5‑8. The lubricant composition prepared by the present invention is a boron-phosphorus-rare earth type friction modifier and antirust agent. Because ricinoleic acid has the characteristics of -OH, -COOH and unsaturated bonds and C long chains, it is also a A good surfactant. The present invention also provides a lubricant composition for preparing a micro lubricant, which is characterized in that it also contains isononyl isononanoate, sodium cocoyl glutamate, castor oil maleate, propylene glycol alginate, myristate Alcohol and other components. 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%.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a lubricant composition, a preparation method thereof and a micro-quantity lubricant prepared by the combination. Background technique [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, It is a challenge to develop a microlubri...
