Abstract

The invention discloses an antibacterial, antiviral, anti-formaldehyde and stain-resistant interior wall full batch powder, and a preparation method thereof. The antibacterial, antiviral, anti-formaldehyde and stain-resistant interior wall full batch powder comprises a full-batch powder main material and a water-based coating; the water-based coating is prepared from a component A and a componentB. The component A comprises water-based hydroxyl acrylic resin, water-based functional titanium dioxide slurry, a mildew-proof bactericide, water and the like, and the component B is hydrophilic aliphatic isocyanate. The full-batch powder main material comprises ash calcium, coarse whiting, cement, deionized water and the like. The preparation method comprises the following steps: preparing the full-batch powder main material, preparing the water-based coating and the like. The surface of the full-batch powder main material is coated with the water-based coating in a spraying or brushing mode, and natural drying is conducted. According to the invention, formaldehyde and indoor VOC are degraded into water and carbon dioxide with the multifunctional water-based coating and a photocatalyst,secondary release does not exist, the coating is high in hardness, cracking and powder falling are avoided after scratching, and a coating layer has good waterproof and mildew-resistant capacity.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a formaldehyde-resistant, anti-bacterial, anti-virus, and anti-pollution interior wall full-batch powder material and a preparation method thereof Background technique [0002] With the development of society and the improvement of people's living standards, people pay more and more attention to the quality of life and at the same time have higher and higher requirements for health and living environment. As an important part, wall coating paint has also attracted much attention. In addition to requiring water-based environmental protection for wall coatings, functional requirements are also put forward for walls used in hospitals, schools and public places. As a place with dense flow of people, medical institutions are also places where multiple germs and viruses exist widely. Some specific places in hospitals are often polluted by blood stains, medical reagents, ...
