Abstract

The invention belongs to the technical field of cutting fluid processing, and in particular, relates to a preparation method of microemulsified cutting fluid. The preparation method includes the preparation steps: grafting phosphotungstic acid with a benzothiazole ionic liquid to prepare an immobilized ionic liquid catalyst for catalyzing a catalytic reaction of rosin borate, so as to effectivelyimprove the lubricating and anticorrosion properties of the cutting fluid; then with toll oil as a raw material and liquid SO3 as a catalyst, carrying out a reaction with monoethanolamine to produce tall oil acid monoethanolamine; and finally, with rosin borate, tall oil acid monoethanolamine, tung oil, mineral oil, swill-cooked dirty oil, fatty alcohol-polyoxyethylene ether, polydimethylsilane, polyacrylate, water and a bactericide as raw materials, preparing the microemulsified cutting fluid. The prepared microemulsified cutting fluid has excellent various properties and good lubrication andrust resistance.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid processing, in particular to a preparation method of microemulsion cutting fluid. Background technique [0002] In the process of metal material processing, in order to reduce the friction damage between the workpiece and the tool during processing and take away the heat generated, cutting fluid needs to be injected between the processed metal material and the tool. Metal cutting fluid can be divided into three categories: emulsified oil, microemulsion, and synthetic cutting fluid. [0003] Microemulsion cutting fluid is a transparent or translucent, isotropic, thermodynamically stable system that spontaneously fuses oil, water, surfactants, co-surfactants and other substances according to a certain formula ratio. At the same time, it is also a new type of metalworking fluid product between emulsified oil and synthetic cutting fluid. It has the lubricity of emulsified oil and the cleaning p...
