Abstract

The invention discloses a preparation method of an environment-friendly water-based metal cutting fluid. The preparation method comprises the steps that: (1) 1/3 of a total amount of water is heated to a temperature of 40-50 DEG C; triethanolamine, polyethylene glycol, isopropanol, sodium molybdate, ethylene disodium tetraacetate, sodium silicate, and methyl benzotriazole are sequentially added into the water; the mixture is mixed by stirring for 20-30min, such that a mixture is prepared; (2) sodium benzoate and monoethanolamine benzoate are added into the mixture, and the mixture is stirred for 20-30min; (2) 1/3 of a total amount of water is heated to a temperature of 70-80 DEG C; glycerin and water-soluble borate are added to the water, and the mixture is stirred for 10-20min; (4) the solution obtained in the step (3) is mixed with the mixture obtained in the step (2), and the mixture is mixed by stirring for 30-40min under a temperature of 50-60 DEG C; and (5) nano-grade silica is added into the mixed solution obtained in the step (4); and the mixture is stirred for 2-4h, such that the cutting fluid is obtained.

Description

Technical field [0001] The invention relates to the technical field of metal cutting processing, in particular to a preparation method of environmentally friendly water-based metal cutting fluid. Background technique [0002] Cutting fluid is widely used in the metal cutting process, and its function is to cool, lubricate, clean, and prevent rust of metal parts. The cutting fluid used in my country's machinery industry is developed from a formula introduced from the former Soviet Union. It is an oil-based emulsion and is a mixed aqueous solution. Its ingredients contain more or less sodium nitrite, which has certain toxic side effects to users; In the process, it is prone to deterioration, serious smell, and environmental pollution. With the continuous progress and development of the machinery industry, the cutting speed of metal cutting equipment continues to increase. The development of machinery puts forward higher requirements on the accuracy and performance of mechanical par...
