General efficient paint remover

Abstract

The invention relates to a general efficient paint remover and its preparing method. The paint remover is prepared by mixing methylene chloride, methanol, formic acid, resordinol, paraffin, surfactant and corrosion inhibitor according to rated proportion and making then react under a certain condition. It has fast depainting speed, good depainting effect, wide application range, and little corrosion to keelson, and non-combustible and hypotoxicity.

Description

technical field [0001] The invention belongs to the technical field of paint removers, and relates to a fast, efficient and safe paint remover and a preparation method thereof. Background technique [0002] During the long-term use of aircraft, ships, bridges, furniture and other objects, the paint film will be eroded by various corrosive media and damaged by mechanical damage, aging, cracking, peeling and peeling will occur, causing the paint film to lose its protection and decoration If you want to repaint, you need to remove the old paint film. To remove the old paint film, mechanical methods have been used in the past, such as manual removal with a scraper, etc., but this method is not only time-consuming and laborious, but also easy to cause mechanical damage to the surface of the substrate, especially for some parts with complex geometric shapes. , and the use of paint strippers can easily solve these problems, especially the use of organic solvent-based paint strippe...

Problems solved by technology

To remove the old paint film, mechanical methods have been used in the past, such as manual removal with a scraper, etc., but this method is not only time-consuming and laborious, but also easy to cause mechanical damage to the surface of the substrate, especially for some parts with complex geometric shapes. , and the use of paint strippers can easily solve these problems, especially the use of organic solvent-based paint removers, which can quickly and easily remove various old paints without causing major damage to the substrate

In recent years, many different kinds of chemical paint strippers have appeared on the market. Although they save time and labor compared with mechanical stripping methods, they also have many limitations, such as limited types of paint stripping, slow stripping speed, and harmful effects on the substrate. In addition, most of these paint removers contain solvents such as benzene and ether, which are flammable and highly toxic
