Abstract

The invention provides trace lubricating oil which is prepared from the following components in percentage by weight: 5-10% of a trace lubricating oil precursor, 70-85% of diesters and 10-20% of polycaster oleate. By adopting the trace lubricating oil provided by the invention, the problems of workpiece lubrication and cooling in the processing process can be well solved; in addition, the oil product provided by the invention is still very good in extreme pressure abrasion resistance under the condition that additives with sulfur, chlorine and the like which are relatively large in pressure to the environment are not used, in addition, a degradation effect can be achieved, and the lubricating oil is not only environmentally friendly, but also capable of effectively prolonging the servicelives of tools.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and relates to a micro-quantity lubricating oil and a preparation method thereof. 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. In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology in recent years. The micro-quantity lubrication technology has solved the above problems such as large amount of lubricant used and serious pollution. Certain problems, mainly lubrication and cooling problems cannot be solved well. In addition, micro lubricants often need to add a large amount of sulfur-containing, chlorine-containing ad...
