[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.

Abstract
The invention provides a lubricant composition. The lubricant composition is characterized by being prepared from saccharose, dicarboxylic acid, fatty acid and polyethylene glycol with the mole ratio being 1:1-1.5:1-1.5:1-3. According to the lubricant composition, due to the fact that the synthesized polyester compound has multiple vacancy -OH, the lubricant composition can effectively adhere to the metal surface, has the excellent lubricity, good extreme pressure antiwear property and good water solubility, is the excellent surfactant, can completely or partially replace traditional extreme pressure anti-wear reagent comprising chlorine, sulphur and phosphorus to be used in a micro amount of cutting fluid, and the requirements of metal machining for lubrication cooling, extreme pressure wear resistance and rust prevention can be met through a micro amount of cutting fluid; the cutting liquid is used in cooperation with a micro lubricating device, the use amount of the cutting fluid can be reduced by 90% or above, and the effects of energy conservation, emission reduction and environmental protection are remarkable.
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 cutting fluid prepared by the composition. 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, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology has solved the above problems such as large amount of lubricant used and serious pollution, but the research on micro-quantity lubricant still has certain limitations in application. The problem is that the lubrication a...
