Green pollution-free cutting fluid

Abstract

The invention relates to a green pollution-free cutting fluid which is prepared from the following raw materials in parts by weight: 10-17 parts of triethanolamine, 11-16 parts of corn bone or corn straw extract, 2.4-5.5 parts of sodium petroleum sulfonate, 7-10 parts of zinc naphthenate, 0.9-1.6 parts of defoaming agent, 8-13 parts of boric acid, 6-13 parts of coconut diethanol amide and 25 parts of water. The cutting fluid has not environmental pollution and is harmless to the human health.

Description

technical field [0001] The invention relates to a green and pollution-free cutting fluid. Background technique [0002] At present, the cutting fluid based on mineral oil and vegetable oil is mainly used in China. Due to the existence of these oils, the cutting fluid is easily corrupted and smelly, so the service life is very short, and the discharge pollution is large. At the same time, the above-mentioned liquid antirust agents are mostly Sodium nitrite is used. Although sodium nitrite has good anti-rust performance, it has an obvious weakness: one is that it is irritating to the skin, and it is easy to cause skin allergies after workers contact it; The amine in the liquid reacts to produce highly carcinogenic amine nitrite. The use of these cutting fluids not only consumes a large amount of mineral oil and vegetable oil, but also causes environmental pollution. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by...
