Abstract

The invention discloses fully synthetic cutting fluid with high abrasion resistance and high antirust performance and a method for preparing the fully synthetic cutting fluid, and belongs to the technical field of technological lubrication. By the aid of the fully synthetic cutting fluid and the method, the problems of poor universality, short user cycles, vulnerability to decaying and deterioration and severe pollution of the traditional cutting fluid mainly can be solved. The fully synthetic cutting fluid comprises, by weight, 0.50%-1.00% of disodium tetraborate decahydrate, 1.00%-2.00% of extreme-pressure agents, 0.02%-0.10% of defoaming agents, 0.08%-0.15% of 1, 2, 3-benzotriazole, 0.50%-1.50% of polyethylene glycol, 1.00%-2.00% of synthetic additive components A and the balance deionized water. The synthetic additive components A in the fully synthetic cutting fluid are multi-effect additives, and oleic acid and triethanolamine are synthesized according to a mass ratio of 1.8-2.0under the condition of constant temperatures ranging from 60 DEG C to 80 DEG C for 3-6 h to obtain the multi-effect additives. The fully synthetic cutting fluid and the method have the advantage thatthe fully synthetic cutting fluid not only is applicable to common cutters, but also is applicable to hard aluminum alloy cutters, can be used for machining diversified materials at high and low speeds and particularly can be used for machining cast iron, carbon steel, stainless steel and the like at high and low speeds.

Description

technical field [0001] The invention relates to the technical field of lubrication and is used for process lubrication in metal processing, in particular to an environment-friendly fully synthetic cutting fluid with high anti-wear and anti-rust performance and a preparation method thereof. Background technique [0002] The development of traditional cutting fluids is based on factors such as process requirements, quality requirements, and economic costs, without considering a series of social development requirements such as resources, environment, and human health. The continuous emergence of new materials has brought new challenges to the development of the metal processing industry, and at the same time made the shortcomings of traditional cutting fluids more prominent. Traditional cutting fluids have poor versatility, short service life, are prone to spoilage due to bacterial growth, and produce pungent odors. In addition, traditional cutting fluids pose certain hazards...
