Abstract

The invention discloses a green microemulsion metal cutting fluid and is characterized in that its formula comprises mixed base oil, synthetic ester, an oiliness agent, an extreme pressure antiwear additive, a clean dispersant agent, an antirust anticorrosion additive, an anti-oxidant, an oil mist inhibitor, a bactericide, an antifoaming agent, an anionic surfactant, a nonionic surfactant and a cosurfactant. A preparation method of the green microemulsion metal cutting fluid comprises the following steps of: firstly preparing an oil phase, heating the base oil to 50-60 DEG C, successively adding the oiliness agent, synthetic ester, the extreme pressure antiwear additive, the clean dispersant agent and the antirust anticorrosion additive, uniformly stirring and mixing to prepare an oil phase system; then preparing a water phase, successively adding the bactericide and the antifoaming agent into water, uniformly stirring and mixing to prepare a water phase system; finally emulsifying the systems, and slowly adding the water phase into the oil phase system to form the green microemulsion metal cutting fluid. The green microemulsion metal cutting fluid provided by the invention has advantages of excellent extreme pressure wear resistance, resistance to hard water, long using period and the like.

Description

technical field [0001] The invention relates to a metal cutting fluid, which belongs to the technical field of chemical industry, in particular to a green microemulsion metal cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting fluid should usually have four major functions, namely cooling, cleaning, lubrication and rust prevention. Since metal cutting fluid is widely used in metal processing, it is improved and innovated continuously. There are formulation improvements for non-water-soluble and water-soluble cutting fluids. [0003] Existing patent reports, such as the improvement of non-water-soluble cutting fluid, usually add organic additives to make it stable at high temperature, enhance lubrication and anti-rust effect; and the improvement of water-soluble cutting fluid is usually to choose different The ratio between minerals, fatty acids, rust inhibitors, preservatives and defoamers ensures good stability; in addition, the imp...
