Abstract

The invention relates to a water-based self-cleaning finish-coat paint, which is prepared from the following components in parts by weight: 30-40 parts of water, 0.1-0.2 part of an antibacterial preservative, 0.1-0.2 part of a mildew preventive, 0.1-0.3 part of a pH modifier, 0.1-0.2 part of a defoaming agent, 0.5-0.7 part of an antifreezing agent, 3.3-3.9 parts of a coalescing agent, 55-65 parts of a styrene-acrylic emulsion, 0.1-0.3 part of a water-based hydrophobic agent, 0.1-0.2 part of nano zinc oxide and 0.1-0.3 part of a thickener. The water-based self-cleaning finish-coat paint has the advantages that the water-based self-cleaning finish-coat paint prepared by combination of the components and the proportions has excellent stain resistance, weather-proof color retention property, water and alkali resistance and adhesiveness, and is safe, nontoxic, environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to the technical field of finish paint, in particular to a water-based self-cleaning finish paint and a preparation method thereof. Background technique [0002] Building exterior wall coatings can beautify the environment and the living room, but due to the poor weather resistance and stain resistance of traditional coatings, the coating will change color and stain after a short period of time. Although the weather resistance can be improved by using glass curtain wall or ceramic tile veneer, it will bring light pollution, increase the self-weight of the building, and have problems such as potential safety hazards. And as urban environmental pollution is intensifying, dust pollution and gas pollution are particularly serious. Building exterior walls, especially high-rise buildings, are being eroded more and more seriously. The ideal external wall protection and decoration materials in the 21st century should be waterproof, UV-r...
