The cutting fluid consists of the following components in part by weight: 10 to 12 parts of triethanolamine, 3 to 4 parts of glycerol, 5 to 7 parts of polyethylene glycol, 3 to 5 parts of nanometer silicon dioxide, 1.5 to 2.5 parts of isopropanol, 5 to 7 parts of sodium molybdate, 2 to 3 parts of sodium benzoate, 3 to 5 parts of monoethanolamine benzoate, 5 to 7 parts of ethylene diamine tetraacetic acid disodium, 7 to 8 parts of water-soluble borate, 1.5 to 2 parts of sodium silicate, 1.5 to 2.5 parts of methyl triazole and 70 to 80 parts of water.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to an environment-friendly water-based metal cutting fluid. Background technique [0002] Cutting fluid is widely used in the process of metal cutting, and its role is to cool, lubricate, clean, and prevent rust of metal parts. The cutting fluid used in my country's machinery industry is developed from the formula introduced from the former Soviet Union. It is an oil-based emulsion, which belongs to a mixed aqueous solution. Its ingredients contain more or less sodium nitrite, which has certain toxic and side effects for users; use In the process, it is easy to deteriorate, the smell is serious, and the environment is polluted. With the continuous progress and development of the machinery industry, the cutting speed of metal cutting equipment continues to increase. The development of machinery also puts forward higher requirements for the precision and performance of mechanica...
