Normal-temperature paint remover and preparation method thereof

Abstract

The invention provides a normal-temperature paint remover and a preparation method thereof. The normal-temperature paint remover comprises, in parts by weight, 2-9 parts of formic acid, 5-20 parts of dimethylaniline, 3-10 parts of propylene phosphate, 2-7 parts of solvent naphtha, 2-5 parts of isopropanol, 1-3 parts of benzoic acid, 2-5 parts of paraffin, 0.2-1.5 parts of organic glass powder, 0.5-3.2 parts of acetophenone, 1-5 parts of benzoic acid, 1.2-4.5 parts of benzaldehyde, 0.2-1.5 parts of aromatic alcohol, 2-8 parts of ethyecellulose, 0.4-2.3 parts of amyl alcoholate, 0.8-2.5 parts of alkylphenol ethoxylates, 0.8-4.5 parts of trichloroacetic acid, 0.5-1.2 parts of ethanol amine, 1-5 parts of triacetate fibres, 2-7 parts of sodium alkyl benzene sulfonate and 0.1-0.6 parts of corrosion inhibitor. The preparation method comprises the step of mixing the various constituents. The paint removal rate of the normal-temperature paint remover provided by the invention can achieve more than 90% and is far higher than the paint removal rate of commercially available products, and the normal-temperature paint remover has an excellent paint removal effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a normal temperature paint remover and a preparation method thereof. Background technique [0002] Along with the rapid development of my country's economy, more and more people have cars, but automobiles are damaged from time to time due to accidents. When refurbishing, the original parts need to be stripped. The paint stripping 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. 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 pa...

Problems solved by technology

Alkaline paint strippers and acidic paint strippers need to be heated when they are used, and the paint stripping efficiency is not high. During the operation, they will produce greater toxicity and severe corrosion to the metal substrate.
