Novel antibiosis exterior wall high solid emulsion paint

Abstract

The invention discloses a novel antibiosis exterior wall high solid emulsion paint, which comprises the following ingredients: 10-20 parts of glycol, 1-3 parts of phosphatidylcholine bilayer, 10-20 parts of stearamide, 2-6 parts of dimethicone, 1-3 parts of sodium benzoate, 200-300 parts of ultrafine TiO2, 100-200 parts of ultrafine SiO2, 100-200 parts of light calcium, 50-60 parts of barium sulfate, 400-500 parts of pure propanal emulsion, 10-20 parts of ester alcohol-12, 2-6 parts of ethoxylated alky-sodium sulfide, 3-5 parts of ammoniacal liquor, 2-5 parts of naphthopyrans and 100-200 parts of water. The invention also discloses a preparation method of the novel antibiosis exterior wall high solid emulsion paint. The novel antibiosis exterior wall high solid emulsion paint has the advantages of strong antibiosis capability, high color change efficiency and simple preparation technology.

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...

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.
