Waterborne coating adsorbing hazardous substances

Abstract

The invention discloses a waterborne coating adsorbing hazardous substances. The waterborne coating is prepared from, by weight, 30-40 parts of waterborne urea resin, 15-20 parts of waterborne nitrocellulose emulsion, 50-70 parts of waterborne alkyd resin, 2-4 parts of cross-linking agent, 20-30 parts of mica sheet, 30-40 parts of corn core powder compound, 2-4 parts of pigment, 2-4 parts of plasticizer, 2-4 parts of anti-flash-rust agent, 2-4 parts of salt-fog resistance agent, 1-2 parts of dispersant, 1-2 parts of defoamer, 1-2 parts of thickener and 50-70 parts of water. The waterborne coating adsorbing the hazardous substances is free of hazardous substances of formaldehyde, benzene, ammonia and the like, can adsorb the hazardous substances emitted by indoor floors, furniture and the like, meanwhile is strong in adhesive force, not easy to peeling-off and good in water resistence, and cannot generate peeling.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based coating that absorbs harmful substances. Background technique [0002] With the rapid development of the paint industry, various special paints for interior walls emerge in endlessly. Manufacturers attract the attention of consumers in terms of color, material and safety. , usually prone to the following problems: the wall is prone to mildew or oxidation, causing the paint to fall off, especially during the rainy season in the south, when the air is humid, it is more likely to have mildew on the interior wall, and the water resistance is poor. Bring a lot of inconvenience. And in most of existing paint products, contain harmful substances such as certain formaldehyde, volatile organic compound, can send out unpleasant smell for a long time usually, environmental performance is relatively poor, brings lasting harm to people's health. Contents of the invention ...
