Abstract

The invention provides an antirust cutting fluid and a preparation method therefor. The antirust cutting fluid comprises, by weight, 18-30% of polyaniline, 2.5-4.5% of benzoic acid, 10-20% of polyvinyl chloride latex, 0.02-0.2% of non-ionic polyacrylamide, 0.3-1.5% of alkyl sulfanilamide sodium acetate, 3-10% of tetrazole, the balance being water. During the preparation processes, according to the formula ratio, polyaniline, benzoic acid, polyvinyl chloride latex, non-ionic polyacrylamide, alkyl sulfanilamide sodium acetate and 20-50% of water are added into a reactor, and mixed evenly. Then according to the formula ratio, tetrazole and the rest water are added, the mixture is dispersed and stirred evenly by a dispenser, and the antirust cutting fluid is obtained. The antirust cutting fluid is low-cost, friendly to human body and the environment, has excellent anticorrosion performance and lubrication capability, and has stable performances at high temperature.

Description

technical field [0001] The invention belongs to the technical field of chemical additives for metal cutting, and in particular relates to an antirust cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used for cooling and lubricating cutting tools and workpieces in the process of metal cutting, cutting and grinding. As well as the characteristics of easy dilution, it belongs to a new type of coolant. Traditional cooling liquid, also known as saponified oil, is a soap-based emulsion composed of mineral oil and emulsifiers. It has the disadvantages of easy rancidity in summer, difficult dilution in winter, and poor anti-rust effect. At the same time, it consumes a lot of energy, produces high costs, and seriously endangers the environment. and the human body. With the enhancement of environmental protection awareness, people have taken the synthesis of environmentally friendly water-based cutting fluids as an i...
