Problems solved by technology

[0002] In the prior art, most of the anti-corrosion coatings are soluble anti-corrosion materials such as glass fiber reinforced plastics, polyurethane, epoxy resin, etc., which are not only inconvenient to use, but also expensive, and the adsorption capacity of materials during construction is poor, especially on the exterior of concrete structures. During surface construction, due to the relatively poor roughness of the outer surface of the concrete structure, it is difficult for anti-corrosion and waterproof coatings with poor adsorption capacity to adhere to the outer surface of the concrete. The protective film cannot achieve the effect of anti-corrosion and waterproof, the surface of the coating is aging faster, and the durability of the product is poor

Abstract

The invention relates to anticorrosive and waterproof materials for buildings, in particular to an anticorrosive and waterproof polymer coating for a concrete structure. The anticorrosive and waterproof polymer coating comprises a liquid material and a powder material, wherein the group A liquid material is prepared from waterborne epoxy resin, polytrifluorochloroethylene resin, vinyl tertcarbonate, silicone resin, polysiloxane, a catalyst, a defoamer and a dispersant; the group B powder material is prepared from graphite flakes, glass flakes, mica flakes, quartz sand, ceramic raw materials, high calcium powder and inorganic pigment by mixing. The anticorrosive and waterproof polymer coating has the cost lower than that of fiber reinforced plastics, polyurethane and epoxy resin, high product adhesion and durability, the surface smoothness of the coating on the outer surface of concrete after construction can be improved substantially, the ageing resistance of the product is good, the coating can be used for longer time, and the anticorrosive and waterproof properties are better.
