Problems solved by technology

The surface of the place where bacteria grow can threaten human health, and it also affects the actual use value of the surface of the object or causes surface denaturation
Traditional antibacterial coatings are added with mercury salts, lead salts, acid salts, etc., which are highly toxic and have a long residual effect, and have been banned from use; however, although the amount of synthetic organic fungicides is small and the effect is good, there are short effective periods and toxicity. Disadvantages such as large size and narrow application range
In the past, activated carbon was widely used to remove odor in the air. With the enrichment of gas on the surface of activated carbon, its adsorption capacity decreased significantly, which limited its application.
Moreover, the current paint color is relatively single, which is difficult to meet human requirements for art and beauty.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a novel antibacterial high-solid latex paint for exterior walls. Background technique [0002] Microorganisms are found on almost all non-biological surfaces, especially in public places, such as: medical care institutions; public places with high risk of infection: stations, hotels, hotels, airports; In the above-mentioned sensitive areas, so-called multi-drug resistant bacteria and pathogenic bacteria and fungi tend to increase. Bacterial growth on the surface of the place can threaten human health, and it can also affect the actual use value of the surface of the object or cause surface denaturation. Traditional antibacterial coatings are added with mercury salts, lead salts, acid salts, etc., which are highly toxic and have a long residual period, and have been banned from use; however, although the amount of synthetic organic fungicides is small and the eff...
