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.
