Chloride-free extreme pressure microemulsion cutting fluid and preparation method therefor

Abstract

Provided is a chloride-free extreme pressure microemulsion cutting fluid. The cutting fluid is prepared from the following raw materials, by weight, 4-5 parts of boric acid, 1-2 benzotriazole, 1-2 parts of octyl decanoic acid, 1-2 parts of lauryl sodium sulfate, 3-4 parts of polyacrylamide, 2-3 parts of urea, 0.8-1.2 parts of span 40, 0.5-1 part of lanthanum nitrate, 12-15 parts of kerosene, 6-8 parts of auxiliary agents and 200 parts of water. The cutting fluid contains no harmful substances of sodium nitrite, phenol, chlorine, mercury and the like, and is safe and environmentally friendly. Through application of boric acid and lanthanum nitrate, the cutting fluid has excellent extreme pressure performances, and workpieces are not easy to damage. The cutting fluid is advantaged by stable emulsification, no delamination, no coacervation, long service time and low cost. The cutting fluid is suitable for processing of a plurality of materials such as cast iron, steel, aluminum, copper, magnesium alloy and the like, and can meet a plurality of processing technology requirements of turning, drilling, grinding, center processing and the like.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a chlorine-free extreme pressure microemulsion 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 t...
