Abstract

The invention relates to a preparation method of an antibacterial and antiviral environment-friendly interior wall modification coating and a product thereof. The preparation method comprises the steps of preparation of nano inorganic antibacterial and antiviral powder, preparation of pure water-based polyurethane acrylate nano narrow-band emulsion and preparation of pure water-based nano antibacterial and antiviral coating. The pure water-based nano-scale dendritic copolyester is used as a base material to prepare the zero-VOC pure water-based antibacterial and antiviral interior wall modification coating, and the pure water-based nano-antibacterial and antiviral coating has the advantages of high coating fullness, good film coating effect, excellent water resistance, air permeability, water impermeability, excellent mildew-proof effect, dust is not prone to falling on the wall facing, stains are not prone to being attached, cleaning is easy, lasting antibacterial and antiviral capacity is achieved, the antibacterial rate of large intestines, golden yellow and the like reaches 99%, and the H1N1 virus killing rate reaches up to 92.3%.

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 a preparation method of an antibacterial and antiviral interior wall coating and a product 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 electric...
