Cryogenic lubrication cutting fluid

Abstract

The invention discloses a cryogenic lubrication cutting fluid, which is made by the following raw materials in parts by weight: 2.5-5.6 parts of triethanolamine, 1.4-6.5 parts of azobisisobutyronitrile, 2.5-4.5 parts of sodium sulfonate, 1.5-4.2 parts of lead tricarboxylate, 3.5-6.7 parts of diisopropanolamine and 50-80 parts of mixture of plant oil and mineral oil. The cryogenic cutting fluid has excellent lubrication anti-wear performance, cleaning cooling property and antirust corrosion resistance, prevents built-up edges, effectively protects cutters, improves the process quality, takes away a large amount of heat in the process, reduces the temperature of the process surface, effectively avoids the defects such as curling and deforming of workpieces due to high temperature and high-temperature combustion of magnesium chips, greatly improves the process precision of the workpieces, and has excellent antirust corrosion resistance capacity.

Description

technical field [0001] The invention relates to a low-temperature lubricating cutting fluid, which belongs to the field of industrial chemical industry. Background technique [0002] The main characteristics of aluminum-magnesium alloys: the die-casting parts are light and thin, with bright surface, light weight, high strength-to-weight ratio, dimensional stability, good shock absorption, fast heat dissipation, antistatic and so on. As a lightweight structural material, aluminum-magnesium alloys are widely used in aviation, aerospace, defense industry, automobile industry and other fields. With the deepening of application, water-based alloy cutting fluid has gradually become the research direction of people. At present, the commercially available alloy cutting fluid products generally have problems such as insufficient lubricating performance, insufficient rust and corrosion resistance, pungent odor, and oxidative combustion of magnesium chips, which may lead to cutting tu...
