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 serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, it is a meaningful research topic to study a micro-lubricant additive that does not contain sulfur and chlorine and has excellent extreme pressure and anti-wear properties. At the same time, the material research of lubricant base oil is also of practical significance.

Abstract

The invention provides a lubrication oil composition. The lubrication oil composition is characterized by being prepared from fatty alcohol and citric acid, wherein the molar ratio of the fatty alcohol to the citric acid is (1.5-2.5):1. The lubrication oil composition prepared by adopting a preparation method is good in lubricity and biodegradability. The invention provides a trace quantity lubrication oil prepared by adopting the lubrication oil composition. The trace quantity lubrication oil is prepared from the lubrication oil composition, iso-octyl palmitate, sodium cocoyl glutamate, an organoboron compound and other components, and can meet the requirements of metal processing for lubrication cooling, extreme pressure wear resistance and rust prevention; in cooperation with a trace quantity lubrication device for using, the using amount of the lubrication agent can be saved by 95% or above, and the effects of energy conservation, emission reduction and environment protection are significant.
