Embodiment Construction

[0011] The following implementation examples further describe the present invention in detail.

[0012] Add an equimolar amount of benzotriazole and 40% formaldehyde aqueous solution to a one-necked flask, then add a certain amount of acetic acid and deionized water, mix well, react at 25°C for 2 hours, and filter and dry the reaction product .

[0013] Add a certain amount of oleic acid into the three-necked flask and heat it to 70°C, then add diethanolamine (half the amount of oleic acid), raise the temperature to 170°C for 3 hours, cool down to 85°C and add diethanolamine (half the amount of oleic acid) ) and a certain amount of potassium hydroxide, continue the reaction, and the amine value of the reactant does not change, which is the end of the reaction. Add boric acid and n-butanol, heat up to 150 ° C, keep the reaction for 4 hours, and end the reaction. Distill the unreacted n-butanol under reduced pressure Alcohol, prepared oleic acid diethanolamide borate.

Abstract

The invention discloses an environmentally-friendly metal cutting fluid, and belongs to a metal cutting fluid suitable for metal processing in the technical field of machining. The environmentally-friendly metal cutting fluid comprises, by weight, 20-35 parts of barium petroleum sulfonate, 5-15 parts of borax, 20-30 parts of triethanolamine, 1-2 parts of methyl silicone oil, 1-5 parts of a calciumand magnesium ion softener, 5-15 parts of an extreme pressure anti-wear agent, and the balance of water, wherein the extreme pressure anti-wear agent is obtained through the following steps: reactingoleic diethanolamide borate with hydroxymethylbenzotriazole to obtain organic borate, and compounding the organic borate with mildly-alkaline calcium sulfonate. The environmentally-friendly metal cutting fluid has the advantages of environmental protection, no pollution, harmlessness to the human body, excellent lubricating and anti-wear performances, avoiding of the generation of cutting bue, and effectiveness in protecting cutters.

Description

technical field [0001] The invention belongs to a metal cutting fluid suitable for metal processing in the technical field of mechanical processing. Background technique [0002] The issue of sustainable development is one of the important issues facing society today, and the metal processing and manufacturing industry is gradually developing towards green manufacturing. Metal cutting is carried out on the basis of extensive use of cutting fluid, and the annual consumption of cutting fluid in my country reaches about 60,000 tons. With the development of the manufacturing industry, the environmental problems caused by metal cutting fluids have become increasingly prominent, because it is of great significance to develop suitable green cutting fluids. [0003] my country has made some progress in water-based cutting fluids, but there are still some differences with foreign water-based cutting fluids, especially in the extreme pressure and anti-wear characteristics of products...
