Abstract

The invention discloses a metal cutting fluid with high extreme pressure resistance, which comprises the following components in part by weight: 16 to 18 parts of barium petroleum sulfonate, 10 to 12 parts of lead naphthenate, 8 to 10 parts of oleic acid, 22 to 28 parts of triethanolamine, 2 to 3 parts of boric acid, 4 to 6 parts of sodium molybdate, 0.5 to 1 part of methyl silicone oil, 3 to 5 parts of borax, 10 to 12 parts of diethanolamine boric acid polycarboxylic acid composite ester, 8 to 10 parts of diethanolamine boric acid maleic anhydride composite ester, 2 to 3 parts of sodium silicate, 3 to 5 parts of nitrobenzoic acid, and 40 to 50 parts of water. A method for synthesizing the diethanolamine boric acid polycarboxylic acid composite ester comprises the step that diethanol amine, polycarboxylic acid and boric acid are subjected to esterification reaction for 2 to 4 h at 150 to 155 DEG C at a mole ratio of 3:1:1. Another method for synthesizing the diethanolamine boric acid maleic anhydride composite ester comprises the step that diethanol amine, maleic anhydride and boric acid are subjected to esterification reaction for 2 to 4 h at 150 to 155 DEG C at a mole ratio of 3:1:1.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a metal cutting fluid with good extreme pressure resistance. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, cutting and grinding. The cutting fluid is composed of various functional additives, and should have good cooling, lubrication, rust prevention and cleaning functions at the same time. In order to save energy, metal cutting oils at home and abroad are currently developing towards the trend of substituting water for oil. Countries around the world are paying more and more attention to the use of water-based cutting fluids. Although my country has made some progress in this regard, there are still some problems compared with foreign samples. There is a big difference, and it still mainly depends on imports from abroad, while the United States has widely used water-based cu...
