Neutral water-soluble paint remover

Abstract

The invention provides a neutral water-soluble paint remover, comprising paraffin, OP emulsifier, alkali, methyl cellulose, phenol, and dichloromethane. Its main advantages are as follows: less volatilization of the solvent and low toxicity; the paint remover is stable Good performance and easy to clean; the paint remover is neutral and will not cause corrosion to the metal substrate and the paint primer on the surface of the substrate; the paint removal efficiency is high, and it can be used in 1.5 hours for various domestic paint films with a thickness of about 50 μm. Internal paint removal, the paint removal efficiency is 100%; the preparation method of the paint remover is simple, the preparation time is short, the stability is good, the paint removal effect is stable, and it can be stored in a sealed place in the dark for half a year or even longer, and it will not affect the use after being stirred evenly Effect.

Description

Neutral water-soluble paint remover technical field [0001] The present invention relates to a paint remover, in particular to a neutral water-soluble paint remover and a preparation method thereof. Background technique Dichloromethane can quickly penetrate into the macromolecule gap of paint film due to its small molecular size, so that paint film can quickly Rapid swelling produces tensile stress that destroys the bonding force between the paint film and the substrate, and the paint film automatically falls off from the surface of the substrate. But it has It is highly volatile and can cause harm to people and the environment. Generally, some volatilization inhibitors are used to control its volatilization for Improve the paint stripping efficiency and storage stability of dichloromethane, and reduce environmental pollution. Industrial paraffin is mostly used as volatile oil in the market Hair inhibitors, because they are not easy to wash off with water, cause post...
