A special coating for interior walls and its preparation method

Abstract

The invention discloses a special coating for interior walls. The coating consists of the following components in parts by weight: 200-300 parts of water, 1-3 parts of alkaloid, 1-3 parts of wetting agent, 2-5 parts of dispersing agent, 2-4 parts of defoamer, 150-250 parts of titanium dioxide, 50-100 parts of calcium carbonate powder, 50-100 parts of bovine bone meal, 150-250 parts of acrylic emulsion, 20-50 parts of vegetable gum composition, 2-4 parts of ethanol parts, 3-5 parts of plant extracts. The preparation process of the present invention is simple, the cost is low, and the bovine bone meal, plant extract and plant glue are used in combination to play a good role in preventing mildew, repelling insects and sterilizing bacteria, and at the same time has a fresh smell; the coating does not contain formaldehyde, benzene, ammonia, etc. Toxic substances, volatile toxic substances achieve zero discharge, and can absorb harmful substances such as formaldehyde emitted from indoor floors, furniture, etc.; the invention also has good air permeability, so that the wall has a breathing function and automatically adjusts the indoor air humidity.

[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; 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 the environmental protection performance is poor, which brings lasting damage to people's bodies. harm

[0003]Although the products of existing paint manufacturers can meet the limit standards of harmful substances stipulated in the national standards, they do not clearly state that they do not contain certain harmful substances. The existence of harmful substances not only cause harm to the human body, but also pollute the environment

Existing paints for interior walls, whether water-based or solvent-based, are all mixed with anti-mildew agents in the liquid paints. However, most of the agents mixed in the paints are pesticides. Sometimes, Organic mercury-based or arsenic-based compounds are also used, so the coating is more or less toxic, harmful to human health, and expensive, so it is urgent to find a cheap, non-toxic, environmentally friendly Antibacterial interior wall paint
