Problems solved by technology

The anti-mold coatings sold on the market also have anti-mold function, but after 1-2 years, the surface of the paint film will be severely molded, which will affect the appearance. , did not play a corresponding role. This type of antifungal agent is highly water-soluble, and if it is in a high-moisture environment for a long time, the antifungal agent in the paint film will flow into the water and fail; , when the temperature is high, it will decompose and change. If the temperature is too high during production or storage, the antifungal agent will change, so that the antifungal effect will not be achieved; Lose the anti-mold effect; (4) The anti-mold property is single and only inhibits common mold species

Abstract

The invention provides a preparation method of mildew-proof waterproof paint. The preparation method comprises the following steps: mixing butyl acrylate, vinyltriethoxysilane, tert-amyl alcohol and carboxylic butadiene-styrene latex, stirring and mixing at a rotation speed of 1000-2000 revolutions per minute for 40-60 minutes to obtain a mixed solution A for later use; mixing tetraethyl orthosilicate, nano-silver, nano-copper, nano-zinc oxide and citric acid, stirring and mixing at the rotation speed of 1000-2000 revolutions per minute for 30-70 minutes to obtain a mixed solution B for lateruse; mixing the mixed solution A and the mixed solution B, regulating the pH value to be 7.8-8.8, raising the temperature to 80-100 DEG C, adding nonylphenol polyoxyethylene ether and 1,2-benzisothiazole, and stirring at a rotation speed of 1500-2500 revolutions per minute for 25-35 minutes; adding polyacrylamide and hydroxyethylmethylcellulose, regulating the temperature to 60-80 DEG C, stirringat a rotation speed of 1000-2000 revolutions per minute for 30-50 minutes, and cooling, thereby obtaining the mildew-proof waterproof paint.

Description

Technical field [0001] The invention relates to the technical field of paint preparation, in particular to a method for preparing an anti-mold and waterproof paint. Background technique [0002] In recent years, the production of architectural coatings has developed rapidly, among which the development of waterproof coatings has been more prominent, the product structure has been continuously optimized, and the development of diversification and functionality is positive. The construction of the paint is to maintain the perfection of the wall decoration. Generally speaking, effective anti-microbial growth materials are added to the paint to achieve anti-mildew and antibacterial effects. At the same time, the anti-mildew materials in the paint can effectively inhibit mold Corrosion to organic matter, thereby extending the service life of the coating. [0003] Especially in the south, the weather in the south is long overcast and rainy, with a lot of rain and heavy humidity, and the...
