The cutting fluid comprises the following components, by weight: 10-12 parts of poly alpha-olefins, 8-10 parts of soybean salad oil, 3-5 parts of triethanolamine, 8-10 parts of diisopropanolamine, 12-14 parts of boric acid, 16-18 parts of oleic acid, 3-5 parts of fatty alcohol-polyoxyethylene ether, 1-2 parts of benzotriazole, 0.6-1 part of phosphate, 1-2 parts of ethylene glycol, 3-4 parts of propylene glycol monomethyl ether, 0.4-0.8 part of imidazoline, 0.5-1 part of methyl silicone oil, 0.4-0.6 part of polyether and 25-35 parts of water.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a microemulsion cutting fluid with good defoaming performance. Background technique [0002] According to the chemical composition of oil, cutting fluid is divided into two categories: non-water-soluble (oil-based) fluid and water-soluble (water-based) fluid. Oil-based cutting fluids have better lubricating properties and poorer cooling effects. Compared with oil-based cutting fluid, water-based cutting fluid has relatively poor lubricating performance and better cooling effect. [0003] The emulsion combines the lubricity and antirust properties of oil with the excellent cooling properties of water, and at the same time has good lubricating and cooling properties, so it is very effective for high-speed and low-pressure metal cutting where a large amount of heat is generated. Compared with oil-based cutting fluids, the advantages of emulsions are greater heat dissipation,...
