Problems solved by technology

Traditional cutting fluids generally contain mineral oil or vegetable oil or surfactants, which are often prone to odor and deterioration in summer, unpleasant smell, high viscosity in winter, difficult to use, more foam during use, non-transparent is not conducive to observing the workpiece, and high price , increase the cost of use, poor anti-rust effect and other issues, which ultimately affect the processing quality of the product
Water-based cutting fluid is popular for its advantages of environmental protection, non-toxicity, easy cleaning, no nitrite, and good emulsification stability. However, the anti-rust and lubricating effects of water-based cutting fluid need to be improved

Abstract

The invention discloses an antirust aqueous cutting fluid and a preparation method thereof. The antirust aqueous cutting fluid is prepared from 18-26 parts by weight of polyaniline, 5-12 parts by weight of serine, 6-14 parts by weight of polyvinyl alcohol, 2-5 parts by weight of sebacic acid, 1-5 parts by weight of a calcium-magnesium ion softener, 5-11 parts by weight of a lubricant, 1-4 parts by weight of an antiseptic, 3-9 parts by weight of sodium cumenesulfonate, 5-10 parts by weight of triethylamine, 2-5 parts by weight of an antirust agent and 20-35 parts by weight of tap water. The antirust aqueous cutting fluid has good corrosion resistance and lubricity, solves the problems of the traditional aqueous cutting fluid, has the advantages of environmental protection, no toxicity, cleaning easiness and no nitrite, is conducive to cutting operation environment and worker health and has a wide application value.

Description

technical field [0001] The invention belongs to the field of metal working fluids, and relates to an aqueous cutting fluid and a preparation method thereof, in particular to an antirust aqueous cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, cutting and grinding. It can reduce the cutting force during cutting and take away the heat generated in the cutting area in time to reduce the The cutting temperature can improve the durability of the tool, thereby improving the production efficiency, improving the surface roughness of the workpiece, and ensuring the machining accuracy of the workpiece. Traditional cutting fluids generally contain mineral oil or vegetable oil or surfactants, which are often prone to odor and deterioration in summer, unpleasant smell, high viscosity in winter, difficult to use, more foam during use, non-transpa...
