Wax solvent for cleaning magnesium alloy or aluminum alloy workpiece

Abstract

The invention discloses wax removal water for cleaning magnesium alloy or aluminum alloy workpieces. The wax removal water is prepared by mixing the following components in parts by weight: 15-20 parts of triethanolamine, 20-30 parts of oleic acid, and 6 parts of soap oil ~10 parts, 8~12 parts of anionic surfactant, 10~15 parts of coconut oil diethanolamide, 3~6 parts of absolute ethanol, 2~5 parts of penetrating agent. The wax removal efficiency of the wax removal water of the present invention reaches more than 97%, the wax removal speed is fast, and the service cycle (reflected in the number of uses) is increased, thereby effectively improving work efficiency and significantly saving production costs. The material is not corroded.

Description

technical field [0001] The invention relates to a dewaxing water used for cleaning magnesium alloy or aluminum alloy workpieces. Background technique [0002] Magnesium alloys and aluminum alloys have excellent physical and chemical properties and excellent surface treatment properties, and are widely used. In order to improve their performance, surface finish and decorative effect, magnesium alloys and aluminum alloys will undergo a series of surface finishing treatments. In recent years, mechanical cloth wheel polishing technology has emerged. When magnesium alloy and aluminum alloy are mechanically polished, the fine polishing cloth wheel should be accompanied by aluminum alloy polishing wax, so that the alloy surface can be polished to a mirror surface. After the alloy is polished, post-treatment (oxidation, These residual waxes must be washed off before coloring, etc. The wax scale of polishing wax is mainly composed of paraffin wax, fatty acid, rosin soap, metal oxide...

AI Technical Summary

Problems solved by technology

Commonly used organic solvents cannot completely remove polishing wax, especially the polishing materials such as metal oxides and carbides on it cannot be effectively cleaned; and chlorine-containing solvents are not only highly toxic, but also tend to hydrolyze. The workpiece will be corroded, not suitable for cleaning magnesium alloy and aluminum alloy, etc.

At the same time, strong acid or alkali is used for wax and degreasing, so it is not suitable for cleaning aluminum alloys and magnesium alloys. Magnesium alloys and aluminum alloys are active metals and are easy to corrode, so they are better than stainless steel, copper alloys, and zinc alloys. The requirements for wax removal water should be strict. At present, some common wax removal water can basically meet its production requirements, but due to the defects of the composition, content and preparation method of wax removal water, there are still slow wax removal speeds and short service life. There is a slight corrosion problem on the base material, and it is not environmentally friendly, and pollutes the water environment
