Environmental-protection coating and preparation method

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.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a wall coating and a preparation method. Background technique [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 It contains certain harmful substances such as formaldehyde and volatile organic compounds, usually emits an unpleasant smell for a long time, and has poor environmental protection ...

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 has poor environmental protection performance

Although the products of the existing paint manufacturers can meet the limit standards for harmful substances stipulated in the national standards, they have not clearly stated that they do not contain certain harmful substances. The harmful substances in the existing paints not only cause harm to the human body, but also polluted environment

Existing environmentally friendly coatings, whether water-based or solvent-based, are mixed with anti-mildew agents in liquid paints. However, most of these agents mixed into paints are pesticides, and sometimes they are also used Organic mercury-based or arsenic-based compounds, so the paint is more or less toxic. Although the effect is good, the ubiquitous safety problems need to be solved
