Problems solved by technology

[0002] With the rapid development of the paint industry, various environmentally friendly paints emerge in endlessly, most of which are relatively expensive. The existing environmentally friendly paints, especially the environmentally friendly paints on the wall, are usually prone to the following problems during use: the walls are prone to Mildew spots or oxidation lead to paint falling off, especially during the rainy season in the south, when the air is humid, it is more likely to have mildew on the wall, and the water resistance is poor, which brings a lot of inconvenience to consumers; most of the existing paint products Contains certain harmful substances such as formaldehyde and volatile organic compounds, usually emits an unpleasant smell for a long time, and...

Abstract

The invention discloses an environmental-protection coating which is composed of following components, by weight, 200-300 parts of water, 1-3 parts of an alkaloid composition, 1-3 parts of an wetting agent, 4-6 parts of a dispersing agent, 4-6 parts of a defoaming agent, 200-250 parts of titanium dioxide, 40-80 parts of talcum powder, 30-70 parts of seaweed mud powder, 30-70 parts of bovine bone powder, 30-70 parts of shell powder, 30-50 parts of medical stone powder, 200-250 parts of an acrylic emulsion, 20-50 parts of a vegetable gum composition, 15-30 parts of glycerin, 2-4 parts of alcohol and 2-4 parts of an extract of flos sophorae. The invention is simple in technology and low in cost. With combination of components such as the shell powder and the like with the extract of flos sophorae, functions such as strong adsorption, sterilization, and anti-mildew are achieved and the coating is fresh in small. The coating is free of toxic substances such as formaldehyde and the like and can absorb harmful substances volatilized from in-door floors. In addition, the coating has excellent air penetrability so that a wall surface has a breathing function and in-door air humidity can be adjusted automatically.
