Problems solved by technology

[0003] At present, there are few types of anti-mildew coatings in China, and the timeliness is poor, which cannot meet the needs of the market
Among the existing antifungal coatings, most of them are solvent-based coatings with good performance, but they are not conducive to environmental protection, especially not suitable for use in hospitals, biological preparation workshops and other places; moreover, some highly toxic antifungal agents are also used Mercury (phenylmercury acetate, phenylmercuric chloride) phenols (pentachlorophenol and its sodium salt) and tin compounds (tributyltin chloride, tributyltin oxide, etc.)

Embodiment 1

[0040] Put 26.5% of deionized water, 0.2% of bactericide, 0.5% of dispersant, 0.1% of wetting agent, 0.5% of leveling agent, 2% of antifreeze, and 0.5% of defoamer into a high-speed disperser to disperse, and add pigment 17%, filler 23%, after adding, stir at medium and high speed (800-2000rpm), and then disperse at high speed with a sand mill until the fineness is ≤45um; while stirring at medium and low speed (400-800rpm), gradually add film-forming aid 2 %, 25% acrylate emulsion, adjust the pH value of the latex paint within the range of 8.3±0.2 with a pH regulator, add 1.0% antifungal agent and stir well, and adjust the viscosity of the latex paint to 30±2mPa.s with 1.5% thickener (25°C), filter to make an environment-friendly long-lasting anti-mildew coating.

Embodiment 2

[0042] Put 21.8% of deionized water, 0.2% of bactericide, 0.5% of dispersant, 0.1% of wetting agent, 0.5% of leveling agent, 2% of antifreeze, and 0.5% of defoamer into a high-speed disperser to disperse, and add pigment 15%, filler 20%, after adding, stir at medium and high speed (800-2000rpm), then disperse at high speed with a sand mill until the fineness is ≤45um; under medium and low speed (400-800rpm) stirring, gradually add film-forming aid 2 %, 35% acrylate emulsion, adjust the pH value of the latex paint within the range of 8.3±0.2 with a pH regulator, add 1.0% antifungal agent and stir well, and adjust the viscosity of the latex paint to 30±2mPa.s with 1.2% thickener (25°C), filter to make an environment-friendly long-lasting anti-mildew coating.

Embodiment 3

[0044] Put 21.5% of deionized water, 0.2% of bactericide, 0.5% of dispersant, 0.1% of wetting agent, 0.5% of leveling agent, 2% of antifreeze, and 0.5% of defoamer into a high-speed disperser to disperse, and add pigment 17%, filler 23%, after adding, stir at medium and high speed (800-2000rpm), and then disperse at high speed with a sand mill until the fineness is ≤45um; while stirring at medium and low speed (400-800rpm), gradually add film-forming aid 2 %, 30% acrylate emulsion, adjust the pH value of the latex paint within the range of 8.3±0.2 with a pH regulator, add 1.5% antifungal agent and stir well, and adjust the viscosity of the latex paint to 30±2mPa.s with 1.0% thickener (25°C), filter to make an environment-friendly long-lasting anti-mildew coating.

Abstract

The utility model relates to an anti-mold cleaning solution and an anti-mold method. The anti-mold cleaning solution consists of, by weight percentage, a special cleaning agent 0.01 to 5% for preventing mold, a cosolvent 0 to 50% and water 50 to 99.9%. The anti-mold method comprises the following steps of: (1) subjecting a base layer to anti-mold treatment using the anti-mold cleaning solution; (2) coating the base layer subjected to anti-mold treatment with an anti-mold coating; and (3) carrying out daily maintenance of the base layer by using the anti-mold cleaning solution.

Description

Technical field: [0001] The invention relates to an anti-mildew lotion and an anti-mildew method. Background technique: [0002] In many industrial production fields, especially in the production environment of organic materials or products rich in microbial nutrient sources, such as food, pharmaceutical, beverage, wine, leather, grain and other industries, coatings are often used as building interior and exterior decoration materials. However, due to the particularity of the production environment in these industries, the humidity and temperature are very suitable for the reproduction and growth of mold and bacteria. The mold growth on the inner wall and ceiling of the production workshop is quite serious, and widespread mold can be seen everywhere. It directly or indirectly It pollutes the environment, makes agricultural and sideline products and industrial products moldy, discolored, and deteriorates, and also infects diseases. At the same time, it will also cause the coa...
