Problems solved by technology

However, there are several major technical problems in the magnesium alloy cutting fluid: first, the magnesium alloy is very active, and the machining fluid is required to effectively inhibit its corrosion; The total hardness of the water is reduced, resulting in demulsification of water-based cutting fluid layers; 3. Magnesium alloy cutting powder is easy to deposit, easy to corrode and discolor during processing, and has problems such as oxidative combustion.

Abstract

The invention discloses anticorrosive, anti-fading and environmentally-friendly water-based magnesium alloy cutting fluid. The anticorrosive, anti-fading and environmentally-friendly water-based magnesium alloy cutting fluid is prepared from the following components in percentage by mass: 5 to 10 parts of base oil, 5 to 15 parts of an oiliness agent, 10 to 25 parts of organic amine, 5 to 15 parts of a synthetic rust inhibitor, 15 to 25 parts of a functional polyether surfactant, 0.2 to 3 parts of an extreme pressure additive, 3 to 8 parts of a solubilizer, 0.1 to 2 parts of a metal corrosion inhibitor, 0.1 to 2 parts of a magnesium alloy anti-fading agent, 0.1 to 2 parts of a bactericide, 0.1 to 1 part of an antifoaming agent, 0.1 to 10 parts of a pH regulator and 15 to 30 parts of water. The nticorrosive, anti-fading and environmentally-friendly water-based magnesium alloy cutting fluid is outstanding in ticorrosive and lubricating and has water resisting performances, and is high in cleaning and cooling effects, and effectively reduces the major technical problems such as corrosion, oxidative combustion, fading of magnesium alloy, demulsification and layering of the cutting fluid in the magnesium alloy processing process; the pH ranges from 9 to 11, and therefore, the demand of magnesium alloy cutting process can be met well.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an anti-corrosion, anti-discoloration and environment-friendly water-based magnesium alloy cutting fluid. Background technique [0002] Magnesium alloys are mainly divided into Mg-Al-Mn series, Mg-Al-Zn-Mn series, Mg-Al-Si-Mn series, Mg-Al-RE series, Mg-Zn-RE series and Mg -Zn-Zr system. The density of magnesium alloy is small, about 2 / 3 of the density of aluminum. It has high specific strength and specific stiffness, strong shock absorption, strong resistance to electromagnetic interference, good dimensional stability, machinability, Electrical and thermal conductivity, etc.; low temperature dependence, small linear shrinkage, high recycling rate, in line with environmental protection requirements. Therefore, magnesium alloys have gained widespread attention in many fields such as automobiles, electronic appliances, and aviation. [0003] With the increasing application of magne...
