Paint removing agent

Abstract

The present invention discloses a paint removing agent, which comprises, by weight, 1-5 parts of dichlorine, 2-6 parts of formic acid, 1-5 parts of carbon tetrachloride, 1-6 parts of ethyl acetate, 5-25 parts of methyl cellulose, 5-11 parts of benzyl alcohol, 3-7 parts of tartaric acid, 3-10 parts of alkylphenol polyoxyethylene ether, 5-11 parts of ethylene glycol anisole, 8-15 parts of methyltriazole, 8-15 parts of mineral oil, 6-12 parts of trichloroacetic acid, 9-18 parts of benzoic acid, 1-8 parts of trichlorotrifluoroethane, 1-7 parts of methyl benzotriazole, 1-5 parts of potassium permanganate, and 1-7 parts of triacetate fiber. According to the present invention, the paint removing agent uses potassium permanganate, such that a certain oxidation effect is provided, and the paint removing efficiency can be improved; carbon tetrachloride, dichloromethane and ethyl acetate are used as the mixed solvent, such that the paint cured on the surface of the substrate can be well dissolved and stripped; and by adding mineral oil, the performance of the paint removing agent can be further improved, the volatility can be reduced, and the paint film on the surface can be well dissolved.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a paint remover. Background technique [0002] With the rapid development of my country's economy, more and more people have cars. However, the paint damage of cars occurs from time to time due to accidents. When refurbishing, the original parts need to be stripped. The paint stripping principle of the paint remover is to use the solvent to dissolve or swell the film-forming substance to destroy the spatial structure of the paint film or the bonding force between the paint film and the substrate. [0003] Common methods for removing paint film include physical methods and chemical methods. Physical methods include flame method, sand blowing method, sand grinding method, etc., but these methods will cause deformation and damage of the substrate, and the effect is not ideal in practical applications. The chemical method usually uses a paint remover to peel off the pai...
