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.
