Abstract

The invention relates to an antimicrobial and mildewproof paint and a preparation method thereof. The antimicrobial and mildewproof paint is prepared from the following raw materials by weight: 15-18 parts of water, 0.2-0.5 part of hydroxyethyl cellulose, 0.1-0.3 part of a water-based multifunctional additive, 0.5-1.0 part of a water-based dispersant, 0.1-0.2 part of a water-based wetting agent, 0.2-0.4 part of a water-based defoaming agent, 8-12 parts of titanium dioxide, 5-7 parts of kaolin, 8-10 parts of talc powder, 8-10 parts of calcium carbonate, 43-45 parts of a styrene acrylic emulsion, 1.5-3.0 parts of a coalescing agent, 0.8-1.0 part of an antifreezing agent, 0.1-0.2 part of a biocide mildewcide, and 0.3-0.8 part of a thickening agent. The antibiont of the antimicrobial and mildewproof paint prepared in the invention is not directly contacted by people and articles, and can achieve antimicrobial and mildewproof effects. And the antimicrobial and mildewproof paint has the advantages of high antimicrobial efficiency, good durability, high safety, and low drug resistance, etc.

Description

technical field [0001] The invention relates to an antibacterial and antimildew coating and a preparation method thereof. Background technique [0002] Microorganisms widely exist in nature, and the suitable conditions for reproduction and growth are usually a temperature of 23°C to 38°C and a relative humidity of 85% to 100%. Therefore, microorganisms can multiply rapidly in many places, especially in areas with frequent moldy and rainy seasons in the south. The reproduction is more rapid; the mass reproduction of microorganisms not only affects the appearance and quality of items, but also pollutes the environment, and even endangers the growth of animals and plants and human health; therefore, antibacterial and antifungal coatings are increasingly favored by consumers. [0003] At present, there are many antibacterial coatings on the market, most of them are antibacterial with nano-silver and other antibacterial substances. The surface of the film will change color, form...
