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 has solved the problems of large amount of lubricant used and serious pollution. However, there are still some limitations in the application of micro-quantity lubricant research. The problem is that the lubrication and cooling problems cannot be solved well, and the environmental friendliness of the lubricant

Abstract

The invention provides lubricating oil composition. The lubricating oil composition is characterized by being prepared from sorbitol and dimer acid in a molar ratio of 1:2-3. The lubricating oil composition has relatively large molecular weight and good lubricity, extreme pressure antiwear property, antirust property and biodegradability, can completely or partially replace the traditional extremepressure antiwear agent containing chlorine, sulfur and phosphorus to be used in environment-friendly degradable minimal quantity lubricating oil, and a small amount of the environment-friendly degradable minimal quantity lubricating oil can meet the lubrication cooling, extreme pressure antiwear and antirust requirements of metal processing; by matching with a minimal quantity lubrication device, consumption of cutting oil can be saved by 95% or higher, 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 an environment-friendly and degradable trace 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. . [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 mainly that the lubrication and cool...
