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

Embodiment 1

[0010] The invention is an improved exterior wall waterproof coating, which is made of the following raw materials in parts by weight:

[0011] 3.5 parts of polyisocyanate, 5.6 parts of acrylic resin, 4.1 parts of nonylphenol polyoxyethylene ether, 6 parts of kaolin, 1.4 parts of phenylethyl naphthol polyoxyethylene ether, 3.3 parts of stearyl polyoxyethylene ether, N- 1.8 parts of methyl fatty amido taurate and 2.8 parts of sorbitol fatty acid ester.

Embodiment 2

[0013] The invention is an improved exterior wall waterproof coating, which is made of the following raw materials in parts by weight:

[0014] 2.5 parts of polyisocyanate, 3.5 parts of acrylic resin, 3.5 parts of nonylphenol polyoxyethylene ether, 3 parts of kaolin, 1.2 parts of phenylethyl naphthol polyoxyethylene ether, 2.5 parts of stearyl polyoxyethylene ether, N- 1.2 parts of methyl fatty amido taurate and 1.8 parts of sorbitol fatty acid ester.

Embodiment 3

[0016] The invention is an improved exterior wall waterproof coating, which is made of the following raw materials in parts by weight:

[0017] 3.8 parts of polyisocyanate, 7 parts of acrylic resin, 4.7 parts of nonylphenol polyoxyethylene ether, 7 parts of kaolin, 1.7 parts of phenylethyl naphthol polyoxyethylene ether, 5 parts of stearyl polyoxyethylene ether, N- 2.2 parts of methyl fatty amido taurate and 3.6 parts of sorbitol fatty acid ester.

[0018] Compared with the existing waterproof paint, the present invention has higher water resistance and water resistance, higher tensile strength, health and environmental protection, reduces environmental pollution, and will not peel off the wall due to rain washing for a long time; it can prevent acid rain washing , the paint film will not peel off after being washed by rainwater, which reduces the probability of rainwater penetrating into the wall, corroding the wall and causing losses.

Abstract

The invention discloses an improved waterproof coating for external walls, which is prepared by the following raw materials by weight: 2.5-3.8 parts of polyisocyanates, 3.5-7 parts of acrylic resin, 3.5-4.7 parts of polyoxyethylene nonyl phenyl ether, 3-7 parts of kaolin, 1.2-1.7 parts of polyoxyethylene phenethyl naphthol ether, 2.5-5 parts of polyoxyethylene stearyl alcohol ether, 1.2-2.2 parts of N-methyl fatty amido taurine salts, and 1.8-3.6 parts of sorbitol fatty alcohol acid ester. When compared with existing waterproof coatings, the coating of the invention is high in water resistance and waterproofness, high in tensile strength, healthy and environment-friendly, can reduce environment pollution, is not liable to wall flaking due to rainwater wash after long-term use, can resist acid rain wash, is not liable to coating film flaking after rainwater wash, and can reduce the probability of loss caused by rainwater infiltration into walls and wall corrosion.

Description

technical field [0001] The invention relates to an improved exterior wall waterproof coating, which 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 wall,...
