AI Technical Summary

Problems solved by technology

Magnesium-aluminum alloys have poor corrosion resistance, and usually need to be coated on the surface of magnesium-aluminum alloys to improve their corrosion resistance
During use or in some special cases, when it is necessary to remove the paint on the surface of the magnesium alloy, a paint remover is required, and the main solvent of the conventional paint remover is an organic solvent such as methylene chloride, xylene, toluene, etc. , these organic solvents have a strong corrosion on the magnesium-aluminum alloy substrate, which affects the subsequent performance of the magnesium-aluminum alloy

Abstract

The invention provides a magnesium-aluminum alloy paint remover. The magnesium-aluminum alloy paint remover comprises, by weight, 60-80 parts of acetone, 8-15 parts of methyl methacrylate, 5-12 parts of polyvinyl alcohol resin, 2-5 parts of sodium palmitate, 4-8 parts of glycerin, 3-7 parts of sodium tripolyphosphate, 2-7 parts of chlorinated paraffin, 1-4 parts of 1-bromohexadecane, 4-9 parts of N-methylimidazole and 2-5 parts of a surfactant. The invention provides a preparation method of the magnesium-aluminum alloy paint remover. The magnesium-aluminum alloy paint remover can effectively remove paint on the surface of a magnesium-aluminum alloy, has high removal efficiency, does not produce obvious corrosion to the magnesium-aluminum alloy base after paint removal treatment and effectively solves problems of corrosion of the surface of the magnesium-aluminum alloy base subjected to paint removal.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to a magnesium-aluminum alloy paint remover and a preparation method thereof. Background technique [0002] Magnesium alloy is an alloy composed of magnesium as the base and adding other elements. It has the advantages of low density, high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, and large impact load capacity. It is mainly widely used in aerospace. In the fields of transportation, chemical industry, etc., among the magnesium alloys, the most widely used ones are magnesium-aluminum alloys. Magnesium-aluminum alloys have poor corrosion resistance, and usually need to be coated on the surface of magnesium-aluminum alloys to improve their corrosion resistance. In the process of use or in some special cases, when it is necessary to remove the paint on the surface of magnesium alloy, it is necessary to use a paint remover...
