Problems solved by technology

[0002]As a new type of wall decoration material, wallpaper has the advantages of beautiful appearance, low price and convenient use. Its application has become more and more extensive in recent years. With the increase of buildings, the types and patterns of wallpaper are also emerging in an endless stream. The production process of wallpaper is generally to coat wood pulp base paper, print or cover the surface with plastic, and then leave the factory for use after cutting into shape. Due to technological limitations, the flame retardant performance of wallpaper has declined compared with previous decorative materials, and paper-based materials have the disadvantages of being easy to absorb water and not being mildew-proof. Therefore, the current market urgently needs a Mildew effect wallpaper to meet the needs

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.

Description

technical field [0001] The invention relates to the technical field of wallpaper, in particular to a mold-proof and flame-retardant wallpaper and a preparation method thereof. Background technique [0002] As a new type of wall decoration material, wallpaper has the advantages of being beautiful, cheap and easy to use. Its application has become more and more widespread in recent years. The process is generally to coat, print or cover the surface of wood pulp base paper, and then leave the factory for use after cutting and shaping. However, due to the limitations of the raw materials and process of wallpaper production, the flame retardant performance of wallpaper is better than that of previous decorative materials. It has declined, and paper-based materials still have the disadvantages of being easy to absorb water and not being mildew-proof. Therefore, the current market urgently needs a wallpaper with both flame-retardant and mildew-proof effects to meet the demand. Co...
