Abstract

The invention provides environment-friendly degradable trace cutting fluid. The cutting fluid is characterized by being prepared from raw materials including chitosan polyethylene glycol fatty acid ester, wherein the use amount of chitosan polyethylene glycol fatty acid ester is 30%-100% of total weight of the raw materials. With the adoption of prepared lubricant composition, synthesized chitosanpolyethylene glycol fatty acid ester has excellent lubricity, good extreme-pressure anti-wear property and excellent water solubility, is a good surfactant and can completely or partially replace a traditional extreme-pressure anti-wear agent containing chlorine, sulfur and phosphorus to be applied to the trace cutting fluid, and requirements for lubrication, cooling, extreme-pressure wear resistance and rust protection of metal processing can be met by a small amount of trace cutting fluid; under cooperation with a trace lubricating device for use, the use amount of the cutting fluid can besaved by 90% or higher, and energy-saving, emission-reducing and environment-protecting effects are remarkable.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and relates to an environment-friendly degradable trace cutting fluid 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 recently. The micro-quantity lubrication technology has solved the above problems such as large amount of lubricant used and serious pollution. The main problem is that the lubrication and cooling problems cannot be solved well. [0003] In addition, micro lubricants often need to add a large amount of sulfur-contai...
