Problems solved by technology

[0005] In recent years, with increasing concern for health and the environment, people have gradually realized that traditional chloride solvent-based paint strippers are gradually being restricted and abolished, even though different levels of dispersants, surfactants, High-efficiency corrosion inhibitors, high-efficiency volatilization inhibitors and thickeners, etc., can reduce the harmful performance of chlorinated solvent-based paint strippers, but this field will not become the development direction of paint strippers in the future

Abstract

The invention provides a high-efficiency paint remover and a preparation method thereof. The paint remover is prepared from hexadecyl trimethyl amine bromide, methyl cellulose, sodium carboxymethyl cellulose, ethylene glycol monobutyl ether, hexamethylenetetramine, triethanolamine, ethyl 3-ethoxy propionate, polyethylene terephthalate, polyvinyl butyral, a penetrant, a corrosion inhibitor, pine oil, dimethyl carbonate, liquid paraffin and deionized water. The preparation method comprises the following steps: adding the hexadecyl trimethyl amine bromide, ethylene glycol monobutyl ether and hexamethylenetetramine into the deionized water, stirring uniformly, adding the methyl cellulose, sodium carboxymethyl cellulose, ethyl 3-ethoxy propionate, polyethylene terephthalate and polyvinyl butyral, stirring, adding the triethanolamine, penetrant and corrosion inhibitor, stirring, adding the rest of components, heating and stirring to obtain the paint remover. The paint remover is used for removing the paint coating on the metal product surface at normal temperature or low temperature, and does not damage the metal product or pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of metal products, and in particular relates to a high-efficiency paint remover and a preparation method thereof. Background technique [0002] Paint remover, also known as paint remover or paint remover, refers to the use of solvents and the interaction between solvent components to effectively remove the surface coverings of various substrates such as metals, templates, furniture, equipment, aircraft and ships ( A class of compounds in paints, coatings, etc.). [0003] The paint film mainly has decoration, protection and special functions, and is generally composed of film-forming substances, solvents, additives and pigments. The paint film is usually obtained by cross-linking and curing of thermoplastic resin at room temperature, such as epoxy paint, alkyd paint, phenolic paint, nitro paint and polyurethane paint, etc. The paint film of such polymers can be swelled or dissolved by su...
