Water-based cleaning agent for magnesium aluminum alloy and preparation method of water-based cleaning agent

Abstract

The invention provides a water-based cleaning agent for magnesium aluminum alloy and a preparation method of the water-based cleaning agent. The cleaning agent comprises stearic acid, phosphatidylcholine, sodium polyacrylate, propanediol butyl ether, sodium xylene sulfonate, dimethyl silicon oil, alkanolamide, sodium metasilicate, benzotriazole, sodium allysulfonate, diacetone acrylamide, dimethylaminoethyl acrylate, a defoaming agent and deionized water. The preparation method comprises the steps of firstly, adding stearic acid, phosphatidylcholine, sodium polyacrylate, propanediol butyl ether and diacetone acrylamide into the deionized water, heating and stirring to obtain a mixture I; then, adding sodium xylene sulfonate, dimethyl silicon oil and alkanolamide into the mixture I, and stirring while adding to obtain a mixture II; next, adding sodium metasilicate, benzotriazole and sodium allysulfonate into the mixture II, and stirring while adding to obtain a mixture III; and finally, adding the left components into the mixture III, heating, stirring, and cooling by standing to obtain the water-based cleaning agent. The cleaning agent is rather high in cleaning rate under the condition of normal temperature, capable of favorably replacing an organic solvent type cleaning agent and free of corrosion to metal.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of metal products, and in particular relates to a magnesium-aluminum alloy water-based cleaning agent and a preparation method thereof. Background technique [0002] Metal cleaning is an essential link in the process of mechanical processing. Metal parts will leave various residues on the metal surface during the process of transportation, processing, manufacturing and maintenance. Therefore, cleaning of metal parts before further use is essential. Moreover, the quality of cleaning also directly affects the service life of metal parts and machines assembled with them, especially for some precision instrument products, such as electronic products, medical products and aviation products. A reasonable cleaning process coupled with a suitable cleaning agent can quickly and effectively remove the dirt and impurities attached to the surface of the metal parts, thereby reducing the corrosion o...

AI Technical Summary

Problems solved by technology

Ordinary cleaning agents leave a lot of residue after use, and it is difficult to meet the requirements for cleaning efficiency

Although there are many water-based cleaning agents for magnesium alloys and aluminum alloys on the market, most of them are high-temperature cleaning, and the cleaning effect is not very good at room temperature.

However, the cleaning rate of some water-based cleaning agents at room temperature on the market is often not high-efficiency. Therefore, it is necessary to study a high-efficiency, environmentally friendly, magnesium, aluminum and its alloy water-based cleaning agent used at room temperature.
