A kind of wall coating and preparation method thereof

Abstract

The invention discloses a wall paint, which is composed of the following components in parts by weight: 250-300 parts of water, 2-4 parts of alkaloid, 2-4 parts of wetting agent, 3-6 parts of dispersing agent, disinfectant 3-5 parts of foaming agent, 150-250 parts of titanium dioxide, 40-75 parts of talc powder, 90-180 parts of shell powder, 200-250 parts of acrylic emulsion, 30-60 parts of vegetable gum composition, 15-35 parts of glycerin, 2-4 parts of ethanol, 3-5 parts of anti-insect and antibacterial agent. The coating of the present invention has simple preparation process and low cost, and the combination of shell powder and insect-proof and antibacterial agent has good insect-proof and sterilizing effects, the wall is not easy to grow mold, and the smell is fresh; it does not contain volatile substances such as formaldehyde, benzene, and ammonia. Toxic substances, and can absorb formaldehyde and other substances emitted from floors, furniture, etc.; the coating also has good air permeability, so that the wall 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 wall paints emerge in an endless stream. Manufacturers attract the attention of consumers in terms of color, material and safety. Most of their prices are relatively expensive. The following problems are prone to occur: the wall is prone to mildew or oxidation, causing the paint to fall off, especially during the rainy season in the south, the air is humid, and the wall is more prone to mildew, and the water resistance is poor, which brings many problems to consumers. Inconvenient; Most of the existing paint products contain certain harmful substances such as formaldehyde and volatile organic compounds, which usually emit an unpleasant smell for a long time and have poor environmental protection performance. Although the products of existi...

Problems solved by technology

[0002]With the rapid development of the paint industry, various wall paints emerge in endlessly. Manufacturers attract the attention of consumers in terms of color, material and safety. Most of their prices are relatively Expensive, the existing wall coatings are usually prone to the following problems during use: mildew or oxidation on the wall is prone to occur, causing the paint to fall off, especially during the rainy season in the south, the air is humid, and the wall is more likely to grow Mildew phenomenon, poor water resistance, brings a lot of inconvenience to consumers; most of the existing paint products contain certain harmful substances such as formaldehyde and volatile organic compounds, which usually emit unpleasant smell for a long time, which is environmentally friendly poor performance

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

At present, the existing coatings with anti-insect and mildew-inhibiting properties, whether water-based or solvent-based, are mixed with anti-mildew agents into the liquid coatings. However, most of the agents mixed into the coatings are pesticides. type, and sometimes organic mercury-based or arsenic-based compounds are also used, so the paint is more or less toxic, harmful to human health, and relatively expensive. Therefore, it is urgent to find a cheap, non-toxic Toxic, environmentally friendly paint with antibacterial and insect-resistant effects
