Problems solved by technology

The coating of architectural exterior wall coatings is exposed to the atmospheric environment and is subjected to changes in the natural environment such as wind, sun, rain, sand, smog, etc., and with the increasingly serious environmental pollution, dust in the atmosphere and suspended If there are more pollutants, it will be easier to powder, discolor, peel off, stain the coating, etc., so that the coating will lose its original decorative effect. For coatings with a strong three-dimensional decorative effect, the coating is easier stained with stains

Abstract

The invention discloses self-cleaning water-based finish-coat paint and a preparation method thereof, and belongs to the field of paint. The self-cleaning water-based finish-coat paint comprises deionized water, a special emulsion for a finish coat, a self-cleaning functional material, a multifunctional auxiliary agent, a dispersing agent, a filming aid, an antifoaming agent, an antifreezing agent, a preservative and a thickening agent. The special emulsion for the finish-coat is used as a main film forming matter and is matched with the modified nano titanium dioxide material to form a paintfilm surface layer and a hydrophobic inner layer with a hydrophobic effect, so that the finish-coat paint for the outer wall has relatively high pollution resistance. The finish-coat paint has good air permeability and waterproofness, the situation that the exterior of a building is damp and the interior of the building is wet is effectively avoided, under the natural condition, the finish-coat paint can achieve the self-cleaning effect through rain wash, and a good environment is provided for living of people. Meanwhile, the production process of the self-cleaning water-based finish-coat paint is simple and efficient.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a self-cleaning water-based finish paint and a preparation method thereof. Background technique [0002] In recent years, natural stone paint, textured paint, and colorful products with strong decorative three-dimensional effect such as natural sand mining paint have been more and more used in the decoration of building exterior walls. The coating of architectural exterior wall coatings is exposed to the atmospheric environment and is subjected to changes in the natural environment such as wind, sun, rain, sand, smog, etc., and with the increasingly serious environmental pollution, dust in the atmosphere and suspended If there are more pollutants, it will be easier to powder, discolor, peel off, stain the coating, etc., so that the coating will lose its original decorative effect. For coatings with a strong three-dimensional decorative effect, the coating is easier Get stained. Therefor...
