Phytic acid silane protection type emulsive cutting fluid added with modified chitosan oligosaccharide surface active agent

Abstract

The invention discloses phytic acid silane protection type emulsive cutting fluid added with modified chitosan oligosaccharide surface active agent. The emulsive cutting fluid is prepared from, by weight, 50-54 parts of polyol ester, 18-19 parts of lauryl diethanol amide, 3-3.3 parts of boric acid, 0.7-0.8 part of p-toluenesulfonic acid, an appropriate amount of petroleum ether, 0.4-0.5 part of methyl triethoxysilane, 5-5.5 parts of phytic acid, an appropriate amount of deionized water, an appropriate amount of absolute ethyl alcohol, 0.2-0.25 part of sodium bromate, 30-34 parts of castor oil polyoxyethylene aliphatate, 8-8.5 parts of petroleum sodium sulfonate, 3-4 parts of sorbitan monooleate, 1-1.5 parts of sodium oleate, 10-11.5 parts of dehydroabietic acid glycidyl ester, 2-2.2 parts of chitosan oligosaccharide, 10-11 parts of 1-Methyl-2-pyrrolidinone and an appropriate amount of acetone. The phytic acid silane protection type emulsive cutting fluid added with the modified chitosan oligosaccharide surface active agent is a waterborne formula, and the lubricating cooling performance is good; meanwhile, in the metal cutting machining process, a layer of protective film can be formed at the surface of metal, and the corrosion inhibition efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of metal processing aids, in particular to a phytic acid silane protected emulsified cutting fluid added with a modified chitooligosaccharide surfactant. Background technique

[0002] With the rapid development of modern machining in the direction of high speed and precision, metalworking cutting fluids are required to have better lubricating, cooling, cleaning and antirust functions in order to obtain ideal machining surfaces. In addition, as people's awareness of environmental protection increases, higher requirements are placed on the environmental performance of cutting fluids. Traditional mineral lubricating oils have excellent lubricating and anti-rust properties, but have poor cooling and cleaning properties and have an impact on the environment; while traditional emulsions and water-based cutting fluids have excellent cooling and cleaning properties and have little impact on the environment, but Lub...
