Abstract

An environment-friendly water-soluble alkaline paint remover is prepared from, by weight, 90-110 parts of glycol ether, 95-115 parts of methyl ethyl ketone, 130-150 parts of magnesium aluminum silicate, 40-60 parts of water glass, 5-15 parts of sodium hydrogen carbonate and 90-110 parts of water. The preparation method includes: adding water into a glass container, adding glycol ether, and stirring for dissolving; sequentially adding methyl ethyl ketone, sodium hydrogen carbonate and water glass respectively, and stirring for dissolving; adding magnesium aluminum silicate to obtain the environment-friendly water-soluble alkaline paint remover. The paint remover is high in paint removing capability, low in toxicity, environment-friendly and nonflammable, is a slightly alkaline agent, thereby being free of corrosion to a matrix, is a water-soluble agent, thereby being free of volatilization, and is harmless to environment and human body and high in applicability.

Description

technical field [0001] The invention belongs to the field of surface treatment of metallurgical materials, and in particular relates to an environment-friendly water-soluble alkaline paint remover and a preparation method thereof. Background technique [0002] Organic coatings are widely used in daily life and industrial production. On the one hand, the role of coatings is to provide a certain protective effect on the substrate, and on the other hand, it is to beautify the appearance of the coated object. In real life, under environmental effects and physical and mechanical effects, with the prolongation of service time, the coating often fails locally or in large areas, such as loss of gloss, powdering, peeling, cracks, scratches, substrate corrosion, etc., or in Defects such as orange peel, cracks, pulverization, etc. occur during the coating preparation process, resulting in the appearance of unqualified products, which requires the coating to be completely removed and r...
