Wax solvent for cleaning magnesium alloy or aluminum alloy workpiece

Abstract

The invention discloses a wax solvent for cleaning a magnesium alloy or aluminum alloy workpiece. The wax solvent is formed by mixing the following components in part by weight: 15 to 20 parts of triethanolamine, 20 to 30 parts of oleic acid, 6 to 10 parts of detergent agent, 8 to 12 parts of anionic surfactant, 10 to 15 parts of coconut diethanolamide, 3 to 6 parts of absolute ethanol and 2 to 5 parts of penetrant. The wax solvent has the wax removal efficiency of over 97 percent and is high in wax removal speed, and the using cycle (which is reflected by using frequency) of the wax solvent is prolonged, so that the working efficiency is effectively improved, and the production cost is obviously saved; and the wax solvent cannot corrode base materials.

Description

Technical field [0001] The invention involves a waxing water for cleaning magnesium alloy or aluminum alloy workpiece. Background technique [0002] Magnesium alloy and aluminum alloy have excellent physical and chemical properties and excellent surface treatment performance, and are extremely widely used. In order to improve their performance, surface smoothness and decorative effects, magnesium alloy and aluminum alloy will be treated with a series of surface refinement.In recent years, the mechanical cloth wheel polishing technology has emerged. When the magnesium alloy and aluminum alloy are polished by mechanical polishing, a special polishing wax of aluminum alloy should be accompanied by the fine throwing wheel to polish the alloy surface to the mirror surface.Coloring, etc.) Before, these residual wax must be washed off.The wax dirt with polished wax is mainly composed of paraffin, fatty acids, muck, metal oxides, and certain inorganic solids.The solid particles are mainl...

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
