Problems solved by technology

[0003] The methods of wax removal treatment mainly include organic solvent method, chemical method, electrochemical method and water-based cleaning agent method, etc. Commonly used organic solvents cannot completely remove polishing wax, especially polishing materials such as metal oxides and carbides on it. Can not be effectively cleaned, chemical or electrochemical wax removal and degreasing must use strong acid or alkali, so it is not suitable for steel cleaning, therefore, the research on wax removal water is of great significance
[0004] At present, there are many kinds of metal wax removal water on the market. Although the cleaning effect of most of the wax removal water is relatively ideal, there are still problems. The metal ions in the wax are relatively sensitive, and after several uses of the wax removal water, a large amount of metal ions dissolved will greatly reduce the wax removal ability, making it difficult to achieve more recycling. On the other hand, the stability of the wax removal water is easy Affected by various factors such as raw materials, preparation process, storage environment, etc., the stability is poor

Abstract

The invention provides wax removing water for cleaning steel parts or copper parts and a preparation method thereof. The wax removing water is prepared from the following components in parts by weight: 20 to 40 parts of oleic acid, 15 to 25 parts of alcohol amine, 15 to 30 parts of nonionic surfactant, 5 to 15 parts of carboxylate surfactant, 2 to 10 parts of dispersant and 10 to 20 parts of water, wherein the nonionic surfactant is a nonionic surfactant compound with different HLB (hydrophile-lipophile balance) values; the carboxylate surfactant is a glycosyl carboxylate surfactant; the dispersant is a compound of sodium polyacrylate and maleic acid-acrylic acid copolymer. The wax removing water provided by the invention is used for surface treatment of the steel parts or the copper parts, has higher wax removing rate and better corrosion resistance, has lower requirements on water quality, can be recycled for multiple times, and has better stability under high-temperature or low-temperature conditions.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a wax-removing water used for cleaning iron and steel parts or copper parts and a preparation method thereof. Background technique [0002] Various alloy materials and iron and steel materials are processed and then mechanically polished, leaving a large amount of solid particle adherents such as polishing paste on the polished surface. These adherents are mainly composed of paraffin, fatty acid, rosin soap, metal oxides, etc. It will cause adverse effects such as foaming and peeling to the electroplating in the subsequent process. It is necessary to thoroughly clean these adherents before leaving the factory or proceeding to the next step, that is, to perform wax removal treatment. [0003] The methods of wax removal treatment mainly include organic solvent method, chemical method, electrochemical method and water-based cleaning agent method, etc. Commonly used o...
