Abstract

The applicant of the invention provides a green environmentally friendly efficient paint removal cream. The green environmentally friendly efficient paint removal cream comprises the following raw materials in parts by weight: 35-50 parts of dibasic ester, 8-16 parts of dipropylene glycol monomethyl ether, 4-9 parts of phenylcarbinol, 12-26 parts of water, 0.2-2 parts of benzotriazole, 2-6 parts of formic acid, 2-6 parts of boric acid, 5-15 parts of ethyl alcohol, 0.2-1.2 parts of NP-10, 1-5 parts of sodium gluconate, 0.01-5 parts of hydroxyethyl methyl cellulose, and 0.05-1 part of polyepoxysuccinic acid. The paint removal cream is a cream, is directly applied on a matrix where a patient is to be removed, and does not flow down to affect the construction operation and the environment; and besides, the paint removal cream is water soluble, is safe and environmentally friendly, and is high in paint removal efficiency.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a green and environmentally friendly high-efficiency paint remover paste. Background technique [0002] The paint film is usually thermoplastic resin and room temperature cross-linking curing resin, such as alkyd resin, nitro paint, epoxy resin, polyurethane paint, silicone epoxy resin paint, etc. The paint film of these polymers can dissolve Or swell in an appropriate organic solvent, and these polymer molecules contain certain active functional groups, such as ester bonds, ether bonds, amide bonds, etc., which are prone to acidolysis and alkali hydrolysis under the action of hot acid or alkali The chemical reaction causes its molecular chain to break, so the old paint film is easily removed by organic solvent paint remover or alkaline paint remover, acid paint remover. [0003] The function of the paint remover is to destroy the spatial structure of the paint film or th...
