Problems solved by technology

[0003] However, antibacterial coatings in the domestic market currently have disadvantages such as poor antibacterial effect, poor adhesion, porous structure, easy moisture absorption, and easy shedding. Penetrate into the wall and corrode the wall, which not only has no antibacterial effect, but also affects the decorative appearance of the building and reduces the service life of the building

Abstract

The invention belongs to the field of building materials, and specifically relates to an antibacterial coating and a preparation method thereof. The antibacterial coating is prepared from the following main raw materials in parts by weight: lupeol, palmatine hydrochloride, coptisine, bergenin, citronellol, rutin, ursolic acid, nanometer Chlorite-schist powder, titanium dioxide, trimethylolpropane,hydrogenated castor oil and manganese acetate. According to the invention, the lupeol, the palmatine hydrochloride, the citronellol, the rutin and the ursolic acid with antibacterial effects are added into the antibacterial coating to improve antibacterial properties of the coating and reduce propagation of bacteria on the surface of the coating; and after the antibacterial coating is coated ontothe surface of a building which is in an environment with easy propagation of bacteria, the building is insusceptible to mildewing.

Description

【Technical field】 [0001] The invention belongs to the field of building materials, and in particular relates to an antibacterial coating and a preparation method thereof. 【Background technique】 [0002] Microorganisms widely exist in nature. Usually, the natural conditions suitable for the reproduction and growth of mold are temperature 23°C-38°C and relative humidity 85%-100%. The walls, ceilings, floors, and underground works of the workshop are suitable for the growth of molds. They multiply rapidly and produce various metabolites of enzymes, acids, and toxins, which affect the appearance and quality of items, pollute the environment, and endanger animals. Plant growth and human health. If ordinary decorative paint is used, it will be corroded by mold to varying degrees, and mold is more serious for organic paint coatings, and the coating corroded by mold will fade, stain, and even fall off. This is because after the mold erodes the coating, it will secrete enzymes, and...
