A kind of stable emulsion type cutting fluid and preparation method thereof

Abstract

The invention provides a stable emulsion type cutting fluid which is prepared from the following raw materials in parts by weight: 12-15 parts of epoxidized soybean oil, 10-12 parts of methoxypolyethylene glycols, 2-3 parts of aluminate coupling agent DL-411, 3-4 parts of dual fourteen carbon alcohol ester, 4-6 parts of butyl acetate, 10-12 parts of polyalkylene glycols, 2-3 parts of (sodium dodecyl benzene sulfonate, 1-2 parts of boric acid, 6-8 parts of additives and 200 parts of water. According to invention, through the adoption of organic esters such as epoxidized soybean oil and the like, under the action of a solvent and a surfactant, the formed emulsion not only has a good lubricating property and high stability, but also has difficulty in turbid sedimentation; moreover, the emulsion has excellent performance in cooling, cleaning, defoaming and rust resistance. The cutting fluid provided by the invention is applicable to cutting and grinding processes of various metal materials; moreover, the service life is long and zero emission can be achieved.

Description

technical field [0001] The invention relates to the field of metal cutting lubrication, in particular to a stable emulsion 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 p...
