Surface self-cleaning coating and preparation method thereof

Abstract

The invention discloses a surface self-cleaning coating and a preparation method thereof. The surface self-cleaning coating comprises such components as 4-15% of deionized water / ester compound, 0.3-2% of flatting agent, 0.3-0.6% of defoamer, 0.4-0.6% of dispersant, 5-10% of nano mineral filler, 30-40% of binder, 1-3% of plasticizer, 10-15% of pigment paste, 1-3% of surface active additive, 1-2% of anti-staining seal-cleaning non-sticking agent, 2-4% of antifungal and moss / sludge / alga growing preventing inhibitor, and 18-28% of curing agent. The surface self-cleaning coating is capable of effectively preventing graffiti and resisting scaling, and self-cleaning; heavy metals or other toxic substances such as organic tin are not contained in the formula, and no chemical surfactant and alkaline products are adopted, and therefore, the film formed after the coating is cured has better durability and the surface of the film cannot be damaged by effective cleaning.

Description

technical field [0001] The invention relates to a functional environment-friendly paint, in particular to a surface self-cleaning paint and a preparation method thereof. Background technique [0002] The problems of polluting the environment and destroying the beauty of the city caused by graffiti and posting on historical buildings, residential and commercial buildings have not been solved. So far, there is no coating on the market that can resist graffiti and posting. Once the walls have been painted with graffiti, it is difficult to remove, unless highly abrasive solvents are used, but this will have a certain impact on the building. [0003] In the prior art, there are some paint protective films used on the surface of buildings to prevent graffiti, but they are only temporary, not the root cause, because it is very difficult to remove graffiti on the surface of buildings. It is necessary to use chemical products, such as organic solvents and chemical surfactants, which...

[0003] In the prior art, there are some paint protective films used on the surface of buildings to prevent graffiti, but they are only temporary, not the root cause, because it is very difficult to remove graffiti on the surface of buildings. It is necessary to use chemical products, such as organic solvents and chemical surfactants, which not only cause harm to the environment, but also affect people's health. As the graffiti on the surface of the building is cleaned, the protective film of the paint is also slow. lose slowly
