High-performance water-based magnesium alloy processing liquid

Abstract

The invention relates to a high-performance water-based magnesium alloy processing liquid which comprises the following raw materials in parts by weight: 3-5 parts of a water-soluble antirust agent, 2-5 parts of a special anti-hard water dispersing agent, 10-20 parts of modified self-emulsifying ester, 3-5 parts of a special coupling agent, 3-5 parts of special amine, 2-5 parts of special phosphate and 2-3 parts of a surfactant, 20-30 parts of base oil and the balance of water. The high-performance water-based magnesium alloy processing liquid provided by the invention has excellent lubricity,and the combination of the special hard water resistant dispersant and the modified self-emulsifying ester enables the product to have an excellent magnesium ion resistant effect and to resist 15000ppm magnesium ions. The special amine and the special phosphate are compounded, so that the product has excellent performance of preventing the magnesium alloy from discoloring, the discoloring of theproduct is effectively prevented, and an excellent use effect is achieved.

Description

technical field [0001] The invention relates to the technical field of magnesium alloy processing fluid, in particular to a high-performance water-based magnesium alloy processing fluid. Background technique [0002] Magnesium alloy is an alloy composed of magnesium and other elements. In the international metal processing industry, the use of water-based lubricating cooling medium for magnesium alloy processing began in the mid-1990s. It first benefited from With the rapid development of the application of materials in the automotive industry and the development of metalworking fluids, there are two main problems in the processing of magnesium alloys: 1. The low ignition point and slow heat dissipation during processing will cause blue light burning; 2. Oxidation and precipitation of magnesium ions lead to The hardness of the cutting fluid increases rapidly. Under the condition of high hardness, the cutting fluid is easily demulsified and delaminated, and it is easy to chan...

[0002] Magnesium alloy is an alloy composed of magnesium and other elements. In the international metal processing industry, the use of water-based lubricating cooling medium for magnesium alloy processing began in the mid-1990s. It first benefited from With the rapid development of the application of materials in the automotive industry and the development of metalworking fluids, there are two main problems in the processing of magnesium alloys: 1. The low ignition point and slow heat dissipation during processing will cause blue light burning; 2. Oxidation and precipitation of magnesium ions lead to The hardness of the cutting fluid increases rapidly. Under the condition of high hardness, the cutting fluid is easily demulsified and delaminated, and it is easy to change color. Therefore, the cutting fluid has a short service life and needs to be replaced frequently. Therefore, there is an urgent need for a high-performance The water-based magnesium alloy processing fluid prevents the discoloration of magnesium alloys during processing
