Abstract

The invention discloses mildew-proof and flame-retardant wallpaper and a preparation method thereof. According to the invention, the mildew-proof layer is arranged on the surface of the wallpaper, so that the antibacterial ability of the wallpaper is enhanced, and the self-cleaning performance of the surface of the wallpaper is enhanced by virtue of the decomposition ability of N-doped zinc oxide contained in the mildew-proof layer; and birnessite used in the flame-retardant layer is utilized to adsorb moisture and decompose formaldehyde, so that the environment-friendly property of the wallpaper is enhanced while the ink layer is protected from stripping, the harm to a human body is reduced, and the wallpaper has a wide application prospect.
