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 above problems such as large amount of lubricant used and

Abstract

The invention provides a lubricating oil composition, which is characterized in that the lubricating oil composition provided by the invention is prepared from the following components (by weight): 100 parts of ricinoleic acid, 8-10 parts of isopropanolamine, 5-8 parts of isomeric alcohol, 3-5 parts of boric acid and 3-5 parts of phosphorus pentoxide. The lubricating oil composition prepared by adopting the preparation method is a B-P-N type friction modifier and an antirust agent, and is good in degradability. The invention also provides trace lubricating oil containing the above lubricatingoil composition, and the trace lubricating oil is characterized by being prepared from the following components (by weight): 10-20% of the lubricating oil composition, 70-80% of diisodecyl adipate and10-20% of polysucrose fatty acid ester. The trace lubricating oil prepared by the invention can meet the requirements of lubrication cooling, extreme pressure wear resistance and rust prevention in metal processing; and the use amount of a lubricant can be saved by more than 95% by matching with a minimal quantity lubricating device, and the effects of energy conservation, emission reduction andenvironmental protection are remarkable.
