Waterproof coating

Abstract

The invention discloses a waterproof coating, comprising the following raw materials in parts by weight: 15-40 parts of polyacrylic emulsion, 3-10 parts of polyurethane, 1-5 parts of an anti-settling agent, 20-40 parts of cement, 5-10 parts of GR composite titanium dioxide pigment, 0.5-5 parts of rosin modified phenolic resin, 2-4 parts of polyisocyanates, 2-4 parts of phenol, 1-2 parts of dimethylbenzene, 0.5-2 parts of silane coupling agent, 1-2 parts of ethylene glycol monoethyl ether acetate, 0.8-1.4 parts of a flatting agent and 0.5-1 part of a defoamer. The waterproof coating disclosed by the invention is excellent in waterproof property, not easy to mould and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof coating. Background technique [0002] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the exterior decoration of buildings is getting more and more attention. Because it is not water-resistant and not waterproof, the paint film will peel off as a whole after being washed by rainwater, which looks unattractive. The requirements for the coating coating on the outer layer of the object are getting higher and higher. The waterproof and anti-seepage problem of the building is related to people's work and living environment, and affects the service life of the bui...

[0002] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the exterior decoration of buildings is getting more and more attention. Because it is not water-resistant and not waterproof, the paint film will peel off as a whole after being washed by rainwater, which looks unattractive. The requirements for the coating coating on the outer layer of the object are getting higher and higher. The waterproof and anti-seepage problem of the building is related to people's work and living environment, and affects the service life of the building. Therefore, if a waterproof performance is prepared , the coating with long service life has become a technical problem that needs to be solved at present
