Description

technical field [0001] The invention relates to a paint remover, specifically an alkaline paint remover, especially an alkaline paint remover containing a highly active corrosion inhibitor nitrobenzene disulfide or a mercaptoquinoline compound. Paint remover can be used to remove the paint layer on the surface of electronic products such as computers and mobile phones. Background technique [0002] Before repainting appliances or equipment parts, it is often necessary to strip the old paint layer. The removal of the old paint layer needs to be based on different requirements, different substrates, and different coatings. Corresponding requirements are put forward for the universality of the paint remover to remove various paint films.

[0004] Most of the inorganic paint removers are sodium hydroxide, which is relatively low in cost and safe to use, but ...

AI Technical Summary

Problems solved by technology

The paint remover overcomes the disadvantages of strong corrosion and long paint removal time of simple inorganic paint removers, and at the same time avoids the shortcomings of organic paint removers such as high toxicity, strong volatility, and serious pollution, and achieves low Toxicity, non-corrosion, fast paint removal and environmental friendly requirements
