Problems solved by technology

[0003] Through the search of existing patent documents, it is found that Chinese invention patents with publication numbers 202010845698.2 and 202010803801.7 disclose technical solutions for anti-virus interior wall coatings, but these patents are based on water-based acrylic resin and / or styrene-acrylic resin / EVA / Organic resins such as vinegar-acrylic water-based emulsion are film-forming substances, and film-forming aids need to be added in the production and film-forming process. There are harmful organic solvents and residues, which will continue to affect the health of users.
Moreover, the interior wall decorative paint of the existing organic resin has low hardness after film formation, poor scrub resistance, short life, and is difficult to clean after the wall is dirty.
[0004] The Chinese invention patent with the application number 202010640905.0 discloses the technical solution of anti-virus interior wall paint, which uses composite silicate as the film-forming material, and its scrub resistance can only reach about 6000 times; Mildew; and the coating is not acid-resistant, and will crack and fall off when encountering acid
[0005] The Chinese invention patent with the application number 202010615798.6 discloses a technical solution for a long-acting slow-release bactericidal antiviral coating and its preparation method and application. Inorganic materials such as calcium carbonate and nano-silicon dioxide are used as film-forming substances. Although this solution can Long-acting slow-release bactericidal antiviral agent, but the water resistance of the wall is poor, and it is not easy to clean the wall after it is dirty, which affects the appearance

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an antibacterial and antiviral functional coating, in particular to an antibacterial and antiviral inorganic ceramic interior wall coating and a preparation method thereof. Background technique [0002] At present, the most commonly used interior wall decoration paint is latex paint, which is a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion, which will continuously release volatile organic compounds such as formaldehyde, and the concentration of harmful gases can be several times higher than that of outdoors. Dozens of times. At the same time, in crowded public places such as hospitals, schools, kindergartens, and catering units, germs (including new coronaviruses, etc.) spread quickly, which can easily cause cross-infection and the spread of infectious diseases, and also aggravate indoor air pollution. In addition, there are a lot of ele...
