Abstract

The invention discloses water-based cutting fluid for metal processing and a preparation method of the water-based cutting fluid. The cutting fluid mainly consists of a lubricating agent, a metal antirust agent, an anti-wear reagent at extreme pressure, a nonionic surfactant, a dispersing agent, an antifoaming agent and water, and the cutting fluid comprises the following components in percentage by weight: 8-12 percent of oleic acid, 1.8-2.5 percent of triethanolamine, 0.3-0.6 percent of boric acid, 0.2-0.5 percent of benzotriazole, 5-8 percent of sodium carbonate, 10-12 percent of polyethylene glycol, 0.2-0.5 percent of dodecylphenol polyoxyethylene ether (OP-10), 0.7-1 percent of glycine betaine, 0.5-0.8 percent of glycerin polyoxypropylene ether and the balance of water. According to the water-based cutting fluid disclosed by the invention, the problems that the conventional water-based cutting fluid is poor in antirust and lubricating performances, low in recycling period and harmful to the human and environment are solved, and the aims of improving the lubricating effect and the antirust performance, realizing harmlessness to the environment and a human body and reducing the production cost of metal processing are achieved by virtue of synthesis of polybasic esters.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a water-based cutting fluid for metal processing 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. According to its medium condition, it can be divided into oil-based cutting fluid and water-based cutting fluid. Oil-based cutting fluid has good rust resistance and lubricity, but its biodegradability is poor, and it pollutes the environment. The cracked products during use are harmful to organisms, and the overall cost of its production Higher, does not meet the requirements of energy conservation and environmental protection. Water-based cutting fluid has good cooling performance and cleaning performance, and the cost is lower than oil-based cutting fluid, and the pollution is small. Its consumption accounts for about 95% ...
