Abstract

The invention discloses a diester-type semisynthetic cutting fluid with high lubrication and high hard water resistance. The cutting fluid comprises, by weight, 30-40% of synthetic ester, 3%-5% of a surface active agent, 12%-20% of an antirust, 2%-5% of a solubilizer, 1%-5% of a corrosion inhibitor, 0.2%-0.5% of an aluminum corrosion inhibitor, 0.5%-1% of a defoaming agent, 2%-5% of a bactericidal agent and the balance of water. The invention also provides a preparation method of the semisynthetic cutting fluid. The method is as below: adding the surface active agent, antirust agent, corrosion inhibitor, solubilizer, aluminum corrosion inhibitor, defoaming agent, bactericidal agent and water in the synthetic diester in order, and mixing evenly to obtain the diester-type semisynthetic cutting fluid with high lubrication and high hard water resistance. The diester-type semisynthetic cutting fluid with high lubrication and high hard water resistance has superior performances in lubrication, hard water resistance, aluminum corrosion inhibition, corrosion resistance, rust proof and defoaming.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a cutting fluid, in particular to a high-lubrication and high-hard-water-resistant diester semi-synthetic cutting fluid and a preparation method thereof. Background technique [0002] Semi-synthetic cutting fluid is the trend and trend of metalworking fluid development today. Its advantages and disadvantages are between emulsion and fully synthetic fluid. It has good cooling, cleaning and rust resistance. The disadvantage is that its lubricity is not as good as Emulsion, hard water resistance is not as good as fully synthetic fluid. [0003] At present, the shortcomings of semi-synthetic cutting fluids used in large-scale machinery, automobiles, bearings and other manufacturing industries at home and abroad are fully exposed. The hard water property is not good, so it cannot be used for the water quality requirements of some areas with high hard water. Seriously restrict the devel...
