Technical Field

The invention relates to the technical field of metal cooling liquid, in particular to noble metal cooling liquid.

Background

The metal processing cooling liquid is cutting liquid, which is industrial liquid used for cooling and lubricating cutters and workpieces in the metal cutting and grinding process, and is formed by scientifically compounding and matching various super-strong functional additives, and has the characteristics of good cooling performance, lubricating performance, antirust performance, oil removal and cleaning functions, anticorrosion function and easiness in dilution. The defects that the traditional soap-based emulsion is easy to smell in summer, difficult to dilute in winter and poor in antirust effect are overcome, the lathe paint is not affected, and the soap-based emulsion is suitable for cutting and grinding ferrous metal and belongs to the most advanced grinding product at present. The cutting fluid has various indexes superior to those of saponified oil, has the characteristics of good cooling, cleaning, rust prevention and the like, and has the characteristics of no toxicity, no odor, no corrosion to human bodies, no corrosion to equipment, no pollution to the environment and the like.

However, as modern machining progresses in the direction of high speed, high strength and precision, the development of hard-to-machine materials such as super-hard materials and super-strength materials also makes the cutting process increasingly difficult. The reasons for the two aspects are that the friction force and the friction heat in the cutting process are greatly improved, and the metal working fluid is required to have better lubricating, cooling, cleaning and rust preventing properties so as to obtain an ideal working surface. Mineral lubricating oil has excellent lubricating and antirust performance, but poor cooling and cleaning performance; the emulsion and the water-based cutting fluid are excellent in cooling and cleaning properties, but poor in lubricating and rust-preventing properties.
