Abstract

The invention discloses a fully synthetic cutting fluid, which comprises the following ingredients in parts by weight: 15-24 parts of polyether, 10-20 parts of triethanolamine, 1-3 parts of boric acid, 0.2-0.5 parts of benzotriazole, phosphoric acid ester 0.5-1 part, 4-10 parts of monobasic acid, 0.2-1 part of acetylenic alcohol ether, 40-70 parts of water, wherein the polyether is a mixture of two trans-block polyethers. The invention also discloses a preparation method of the above-mentioned fully synthetic cutting fluid, which comprises adding the components into a container one by one or simultaneously and stirring them evenly. The present invention does not need to add organic silicon defoamer, relying on the mixing of various substances in proportion to achieve the effect of low foam and self-defoaming; at the same time, the low surface tension of acetylenic alcohol ether and the orientation to the metal surface are used to enhance the fully synthetic processing fluid Adhesion to the substrate, so as to exert excellent lubricating, cooling and antirust performance. The preparation method of the invention has the advantages of simple process, environmental protection and energy saving, and is suitable for large-scale production and use.

Description

technical field [0001] The invention belongs to the technical field of metal cutting and particularly relates to a fully synthetic cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial fluid used in metal cutting and grinding to cool and lubricate tools and workpieces. In addition to lubricating and cooling functions, it usually also has functions such as cleaning and rust prevention. Cutting fluid can be divided into oil-based cutting fluid and water-based cutting fluid. Compared with water-based cutting fluid, oil-based cutting fluid has better lubricating performance, but the cooling effect is poor. At the same time, oil-based cutting fluid also has disadvantages such as easy mildew and difficult follow-up treatment. Water-based cutting fluids can be divided into emulsions, semi-synthetic fluids and fully synthetic fluids. Since fully synthetic cutting fluid does not contain mechanical oil, it is significantly supe...
