Problems solved by technology

[0004] So far, there are many kinds of metal wax removal water on the market, but most of the products have slow wax removal speed, unsatisfactory wax removal effect, poor rust resistance of the cleaned metal products, and slight corrosion to the substrate. It is not environmentally friendly and pollutes the water environment

Abstract

The invention discloses a wax solvent for cleaning steel pieces or copper pieces and a preparation method of the wax solvent and relates to the technical field of metal surface treatment. The wax solvent is prepared from, by weight, 15-25 parts of diethylenetriamine, 8-16 parts of monoethanolamine, 4-12 parts of triethanolamine, 10-20 parts of coconut oil fatty acid diethanolamide, 2-8 parts of methyl alcohol, 15-25 parts of oleic acid, 2-10 parts of nonylphenol polyoxyethylene ether and 10-18 parts of water. The wax solvent has the good wax removing effect on the steel pieces and the copper pieces, has very high solubilizing and dispersing ability and can completely remove wax scales on the workpiece surfaces in a short time, and the wax removing efficiency reaches more than 95%; and meanwhile, a layer of protective film is formed on the surface of each steel piece and each cooper piece by the wax solvent, the corrosion inhibition is achieved, and therefore the antirust period is long.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a dewaxing water used for cleaning iron and steel parts or copper parts. Background technique [0002] Various alloy materials (copper alloy, aluminum alloy, zinc alloy) and iron and steel materials will be mechanically polished after processing, and solid particles such as polishing paste will remain on the polishing surface. Blistering, peeling and other adverse effects. Wax removal is the first process of pre-treatment of metal plating parts. The speed of wax removal and the thoroughness of wax removal are of great significance to the subsequent processing of alloy materials. Therefore, it is of great significance to choose a good wax removal water. [0003] At present, the wax removal methods mainly include the following categories: organic solvent method, chemical method, electrochemical method and water-based lotion method. Commonly used organic solvents c...
