Self-emulsified cutting fluid and preparation method thereof

Abstract

A self-emulsified cutting fluid is prepared from the following raw materials in parts by weight: 3-4 parts of sodium molybdate, 2-3 parts of disodium ethylenediamine tetraacetate, 2-3 parts of sodium silicate, 3-4 parts of linoleic acid, 1-2 parts of alkenyl butanedioic acid, 20-23 parts of soybean oil, 20-24 parts of propylene glycol, 1-2 parts of trimethylolpropane, 3-4 parts of sodium dodecyl benzene sulfonate, 1-2 parts of ammonium persulfate, 6-8 parts of an auxiliary agent and 200 parts of water. The cutting fluid provided by the invention has excellent lubricity by employing soybean oil and has excellent antirust anti-corrosion property by employing sodium molybdate, disodium ethylenediamine tetraacetate, linoleic acid and alkenyl butanedioic acid; and the cutting fluid has no peculiar smell, no toxicity and no pollution, good stability and extremely high hard-water resistance, and is suitable for cutting processing of various aluminium, magnesium alloy, cast iron and stainless steel.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a self-emulsifying cutting fluid and a preparation method thereof. Background technique [0002] The cutting fluid should have good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, and easy dilution. At present, cutting fluid can be divided into two categories, oil-soluble cutting fluid and water-soluble cutting fluid. Generally, oil-soluble cutting fluid has good lubricating performance, but poor cooling performance, and contains a large amount of organic matter, which pollutes the environment. Although some water-soluble cutting fluids have good cooling performance, they also have the problem of poor lubricity and anti-rust effect. It is very important to have a cutting fluid that does not corrode the equipment and does not pollute the environment. Contents of the invention [0003] The ob...
