Problems solved by technology

The paint used on the exterior wall of the building is exposed to the air with the wind and the sun, and the dust is easy to adhere to the surface of the paint. After a period of time, the brand-new exterior wall paint will become dirty and inconvenient to clean. For the sake of beauty, only Can be repainted, resulting in a great waste of resources
[0003] At present, the antifouling coatings for construction on the market have the following problems: first, most of them are solvent-based systems, and the environmental protection effect is poor; After -5 years, it is easy to get dust, which will cause the light paint to become dirty and need to be cleaned frequently

Abstract

The invention discloses building antifouling coating. The building antifouling coating mainly comprises polyacrylate, light calcium carbonate, titanium dioxide powder, infrared ceramic powder, hollowceramic micro-spheres, a nanometer-sized antifouling auxiliary, dispersing agents, antifreezing agents, thickening agents, wetting agents, defoaming agents, coalescing agents, film formation catalystsand water. Inorganic modified graphene oxide is used as the antifouling auxiliary. The building antifouling coating has the main advantages that metal ions are attached to the surfaces of the graphene oxide, are treated by polycarboxylic acid type efficient water reducers and then are no longer bonded with calcium ions generated after the light calcium carbonate in the building antifouling coating is dissolved, good dispersion effects can be realized, trace titanium dioxide P25 is attached to the surfaces of the graphene oxide, and accordingly excellent self-cleaning effects can be realized;the added trace film formation catalysts act with organosilicon compounds and the polyacrylate, and accordingly the film formation properties can be obviously improved; the building antifouling coating does not contain harmful organic solvents or other toxic and harmful substances and is an environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation coatings, in particular to an antifouling coating for buildings and a preparation method thereof. Background technique [0002] Most of the exterior walls of modern buildings are constructed of building materials such as reinforced concrete, cement prefabricated parts or masonry, and the main component of most of the substrates that exterior wall coatings face is cement. The paint used on the exterior wall of the building is exposed to the air with the wind and the sun, and the dust is easy to adhere to the surface of the paint. After a period of time, the brand-new exterior wall paint will become dirty and inconvenient to clean. For the sake of beauty, only It can be repainted, resulting in a great waste of resources. [0003] At present, the antifouling coatings for construction on the market have the following problems: first, most of them are solvent-based systems, and the...
