Cutting fluid and preparation method thereof

Abstract

The invention provides cutting fluid. The cutting fluid is prepared from the following components in percentage by weight: 15 to 25 percent of triethanolamine borate, 2 to 3 percent of sebacic acid, 3to 5 percent of a tricarboxylic acid rust inhibitor, 1 to 2 percent of a non-ferrous metal inhibitor, 6 to 10 percent of synthetic ester, 3 to 5 percent of a water-based extreme pressure lubricant, 5to 10 percent of a cationic surfactant, 3 to 5 percent of a coupling agent, 5 to 8 percent of fatty acid amide, 3 to 5 percent of synthetic sodium sulfonate, 8 to 10 percent of tall oil fatty acid, 3to 5 percent of a bactericide, 0.2 to 0.5 percent of a defoaming agent, 2 to 3 percent of a mildew preventive and the balance of base oil, wherein the sum of the weight percent of all the componentsis 100 percent. The invention also provides a preparation method of the cutting fluid. The cutting fluid provided by the invention can meet general requirements of the cutting fluid, and also has theadvantages of better sterilization, mildew property and antioxidant property.

Description

technical field [0001] The invention relates to a cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid (coolant) is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. Cutting fluid is made of a variety of super functional additives through scientific compounding At the same time, it has good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, and easy dilution. Cutting fluid overcomes the shortcomings of traditional soap-based emulsion, which is easy to smell in summer, difficult to dilute in winter, and poor anti-rust effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is currently a leading grinding product. . [0003] Chinese patent application CN201710373163.8 discloses an environment-friendly microemulsion cutting fluid and its pr...
