Abstract

The invention relates to an environment-friendly water-soluble cutting fluid for magnesium alloy cutting, which comprises the following components in parts by weight: 5-20 parts of organic acid, 15-30 parts of organic amine, 5-16 parts of lubricant, 3-11 parts of emulsifier, 1-6 parts of corrosion inhibitor, 0.1-0.5 part of defoaming agent, 0.1-3.5 parts of bactericide and 15-70 parts of water. The magnesium alloy cutting fluid has the advantages of favorable abrasion resistance, favorable hard water resistance, favorable rust and corrosion resistance, and is capable of effectively protecting the cutter and prolonging the service life of the cutter. The water-soluble cutting fluid can quickly take away the heat generated in the machining process, lower the temperature of the machined surface and effectively avoid the defect of high flammability of the magnesium chips due to high temperature. The aluminum-magnesium alloy cutting fluid provided by the embodiment of the invention does not release hydrogen when being used for magnesium alloy cutting, thereby ensuring the safe proceeding of the production process.

Description

technical field [0001] The invention relates to a metal processing fluid, in particular to an environment-friendly water-soluble cutting fluid for magnesium alloy cutting. Background technique [0002] Magnesium alloys have the advantages of low density, high specific strength and specific stiffness, good dimensional stability and machinability, and excellent electrical and thermal conductivity; in addition, they also have excellent performance in electromagnetic shielding and shock absorption. As a good lightweight structural material, magnesium alloys are widely used in many fields such as automobiles, ships, aerospace, electronic appliances, etc. [0003] Magnesium is an active metal, and the corrosion resistance of magnesium and magnesium alloys is poor, which is the bottleneck restricting the application potential of magnesium as a structural material. Water-based magnesium alloy cutting fluid has two major technical difficulties: one is to effectively inhibit the corr...
