Problems solved by technology

[0004] However, most anti-friction and extreme pressure microemulsion cutting fluids on the market now use sulfur, phosphorus, and chlorine type extreme pressure additives. The existence of chloride ions can easily cause corrosion of ferrous metals, and sulfur-containing systems are not suitable for copper and copper. Copper alloy processing, in addition, these additives can easily cause the reproduction of microorganisms, affect the performance of the working fluid, and it is troublesome to manage

Description

technical field [0001] The invention relates to a high-performance microemulsion cutting fluid, which belongs to the field of metal cutting fluid. Background technique [0002] Metalworking fluid chemistry evolved from simple pure oils (cutting oils) to complex water-based technologies throughout the 20th century. From 1910 to 1920, in order to improve the cooling performance of cutting oil and overcome its shortcoming of being easy to catch fire, emulsion was first developed. The water in this metalworking fluid keeps the tool cool and reduces wear, thus extending the life of the tool, but it has poor rust resistance. In the 1950s, fully synthetic metalworking fluids appeared on the market for the first time. Compared with emulsion fluids, fully synthetic fluids have better cooling and rust protection in machining, as well as better hard water stability and biological stability, resulting in longer service life; but their lubricity is not as good as Emulsion, difficult t...
