Problems solved by technology

[0003] According to domestic investigation and analysis, the surface of polluted buildings, especially some food processing, breweries, manufacturing plants and other workshops and warehouses, wall molds mainly include Aspergillus terreus, Aspergillus niger, Penicillium fungus and Aureobasidium pullulans. Especially during the rainy season in the south, these molds are extremely active and reproduce at an alarming rate, polluting the wall, affecting the decorative effect, and endangering the health of animals, plants and humans
[0004] At present, most of the anti-mold coatings on the market use the method of directly adding organic anti-mold additives to improve the anti-mold properties of the coatings. The action time is short. With the decomposition of organic matter, the anti-mold properties will gradually disappear, and harmful microorganisms will form drug resistance. And some microbes can negatively impact humans and the environment

Abstract

The invention discloses a mildew-resistant water-based paint for an interior wall and a preparation method thereof. The mildew-resistant water-based paint for the interior wall comprises 25-35 parts by weight of an acrylic emulsion complexed with silver ions, 5.0-7.5 parts by weight of an opaque polymer, 16-18 parts by weight of titanium dioxide, 3-5 parts by weight of diatomite, 7.5-10 parts by weight of ground calcium carbonate, 0.8-1 part by weight of a freezing-and-thawing-resistant stabilizer, 1-2 parts by weight of a film-forming aid, 0.5-0.8 part by weight of a dispersing agent, 0.3-0.5part by weight of a thickener, 0.1-0.2 part by weight of a wetting agent, 0.1-0.3 parts by weight of an antifoaming agent, 0.1-0.3 part by weight of a preservative, 0.5-0.8 part by weight of an anti-mold agent, 0.2-0.3 part weight of a leveling agent and 20-30 parts by weight of water. The mildew-resistant water-based paint of the invention has the advantages of friendliness to environment, highcovering power, strong adhesion, good leveling properties, excellent and long-lasting mildew resistance, good comprehensive performance, high cost performance, strong applicability, low gloss at a measurement angle of 85 degrees, etc., and can be widely used in food processing plants, pharmaceutical plants, underground garages, grain depots, breweries and other places.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular, the invention relates to an anti-mildew interior wall paint and a preparation method thereof. Background technique [0002] Anti-mildew coating is a functional coating that can inhibit the growth of mold. Traces of mold can be seen in damp buildings, exterior surfaces, walls, floors, ceilings, and underground works of workshops with constant temperature and humidity. Affected by mold, the surface of the coating will be discolored, black spots, stained or even peeled off. The main reason is that the mold will secrete enzymes after eroding the coating, and the enzymes will decompose the organic film-forming substances in the coating film as nutrients, thereby damage the coating. [0003] According to domestic investigation and analysis, the surface of polluted buildings, especially some food processing, breweries, manufacturing plants and other workshops and warehouses, wall molds ...
