▎ 摘　　要

NOVELTY - Air purifying wallpaper comprises a decorative surface layer and a wallpaper base material layer under the decorative surface layer. A photocatalyst coating is coated on the upper surface of the decorative surface layer. Three waterproof and breathable films are arranged between the decorative surface layer and the wallpaper substrate layer. A graphene layer is sandwiched between adjacent waterproof and breathable membranes. The photocatalyst coating comprises a nano titanium dioxide particle layer. The thickness of the waterproof and breathable film is 1.3-1.8 mm. The thickness of the graphene layer is 0.8-1.2 mm. USE - The wallpaper is useful for degrading formaldehyde, benzene, toluene, ammonia and other harmful substances in the air. ADVANTAGE - The wallpaper: can be made thinner; has good flexibility, higher mechanical strength and longer service life; eliminates bad odors; has natural antibacterial and deodorizing functions, which can effectively purify the air. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the air purifying wallpaper.
