Improved difficult-flaking waterproof coating material

Abstract

The invention discloses an improved difficult-flaking waterproof coating material. The improved difficult-flaking waterproof coating material is prepared from the following raw materials in parts by weight: 2.5-3.8 parts of hexabromocyclododecane, 3.5-7 parts of tetrahydrofuran, 3.5-4.7 parts of nonylphenol polyoxyethylene ether, 3-7 parts of polyvinyl acetate emulsion, 1.2-1.7 parts of phenethyl naphthol polyoxyethylene ether, 2.5-5 parts of octadecanol polyoxyethylene ether, 1.2-2.2 parts of N-methyl fatty amide taurine salt and 1.8-3.6 parts of fatty alcohol sorbate. Compared with the existing waterproof coating materials, the waterproof coating material has the advantages that the water resistance and waterproofing performance are higher, the tensile strength is high, the waterproof coating material is healthy and environmental-friendly, the environmental pollution is reduced, and wall body flaking caused by rainwater scouring can not occur during long-time use; the waterproof coating material can prevent acid rain scouring, and a coated film can not flake off after the coated film is subjected to rainwater scouring, so that the probability that loss is caused due to the fact that rainwater penetrates into wall faces and corrodes the wall faces is reduced.

Description

technical field [0001] The invention relates to an improved 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, corro...

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
