A kind of environmental protection coating and preparation method thereof

Abstract

The invention discloses an environmentally friendly coating, which is composed of the following components in parts by weight: 200-300 parts of water, 1-3 parts of alkaloid composition, 1-3 parts of wetting agent, 4-6 parts of dispersing agent, 4‑6 parts of defoamer, 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 acrylic emulsion, 20-50 parts of plant gum composition, 15-30 parts of glycerin, 2-4 parts of ethanol, and 2-4 parts of Sophora japonica extract. The invention has simple process and low cost, and the combination of shell powder and other ingredients with Sophora japonica extract has strong adsorption, sterilization, and anti-mold effects, and has a fresh smell; the product does not contain toxic substances such as formaldehyde and can absorb indoor floors, etc. It also has good air permeability, so that the wall mask has a breathing function and automatically adjusts the indoor air humidity.

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
