Environmental-protective solvent-type paint remover

Abstract

The invention aims to prepare an environmental-protective solvent-type paint remover which is mainly characterized by being prepared from following solvents: propanediol butyl ether, ethylene glycol butyl ether, turpentine and ethyl acetate; and following components: a nonionic surfactant high-carbon primary alcobol ethoxylate, a nonionic surfactant high-carbon acid diethanolamide and potassium hydroxide. The environmental-protective solvent-type paint remover is a shallow-yellow liquid in appearance, is slightly soluble in water, is 8-10 in pH value and has a fragrant smell. The paint remover, when being used, can be directly sprayed onto a painted surface of an object by a spray gun. The paint remover is free of chlorine solvents and benzene solvents so that the paint remover does not damage atmosphere and is harmless to human skin. The paint remover is free of waste gas, waste water and solid waste during a preparation process and is in conformity with a national environmental protective production standard.

Description

【Technical field】 [0001] The invention lies in the manufacture of an environment-friendly solvent-based paint remover. 【Background technique】 [0002] Paint coatings can be used to protect and decorate objects, but in the process of use, the paint film will be damaged or gradually deteriorated. Due to aesthetic reasons, these objects often need to be repaired and updated, and the old or damaged coating needs to be removed before being renewed. Spraying of paint. At present, there are physical methods and chemical methods to remove the paint film. Physical methods generally use mechanical methods, including flame method, sand blowing method and knocking shovel method. Sand grinding, knife scraping, fire and other methods often make the substrate uneven, Deformation, even the substrate may be broken down and damaged, and at the same time, it will leave a dead angle, so the mechanical method is time-consuming and laborious, and it is difficult to achieve high removal quality;...

At present, there are physical methods and chemical methods to remove the paint film. Physical methods generally use mechanical methods, including flame method, sand blowing method and knocking shovel method. Sand grinding, knife scraping, fire and other methods often make the substrate uneven, Deformation, even the substrate may be broken down and damaged, and at the same time, it will leave a dead angle, so the mechanical method is time-consuming and laborious, and it is difficult to achieve high removal quality; the chemical method is very convenient to remove paint, efficient, simple, and high-quality paint removal , so the application of chemical paint remover is more and more widely
