Waterproof paint not liable to peel off

Abstract

The invention discloses waterproof paint not liable to peel off. The paint is prepared from following raw materials by weight: 2.5-3.8 parts of dibromomethane, 3.5-3.7 parts of tetrahydrofuran, 3.5-4.7 parts of nonylphenol polyoxyethylene ether, 3-7 parts of kaolin, 1.2-1.7 parts of phenylethyl naphthol polyoxyethylene ether, 2.5-5 parts of octadecanol polyoxyethylene ether, 1.2-2.2 parts of N-methyl-alkylamido taurine salt and 1.8-3.6 parts of a sorbitol-fatty acid ester. Compared with waterproof paint at present, the paint provided by the invention has high water resistance, high water proofness and high tensile strength and is healthy and environmental friendly; environment pollution is reduced and wall peeling off caused by rain wash after longtime use is avoided; the paint provided by the invention can prevent being washed by acid rain; and the paint film wound not peel off after rain wash, thus reducing the probability that rain permeates into the wall and corrodes the wall to cause losses.

Description

technical field [0001] The invention relates to a waterproof paint which is not easy to fall off, and belongs to the field of building materials. Background technique [0002] At present, traditional paints are widely used in the decoration of building walls. Most of the paints are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Therefore, it is generally only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the outdoor decoration is getting more and more attention. But outdoors are different from indoors. Environmental pollution is getting more and more serious. The rainwater outside is acid rain, so waterproofing alone is not enough. It is also necessary to prevent rain from acidifying the coating. Otherwise, the paint film will be damaged after being washed by rainwater. If the whole peels off, the rainwater will seep into the wall, corrode the wal...

Problems solved by technology

However, outdoors are different from indoors. The environmental pollution is getting more and more serious. The rainwater outside is acid rain, so it is not enough to be waterproof, and it must be able to prevent the rain from acidifying the coating. Otherwise, the paint film will be damaged after being washed by rainwater. If the whole peels off, rainwater will seep into the wall, corrode the wall, and cause damage
