Problems solved by technology

However, the temperature of the indoor environment where the wallpaper is located will change greatly with the change of seasons, and the air permeability of the resin glue surface layer is extremely poor, which makes the local area of ​​the wallpaper prone to bubbling and affects the decorative effect
Bubbles on the surface of the wallpaper will affect the waterproof and moisture-proof effect of the wallpaper, and the humidity in the indoor environment is also changing, which makes the surface of the wallpaper easy to be damp and moldy, and it is easy to breed and attach bacteria on the surface of the wallpaper
Both the resin surface layer and the adhesive contain a large amount of organic solvent additives, such as formaldehyde, benzene, toluene, etc., which are likely to cause environmental problems

Abstract

The invention relates to an antibacterial and mildew-proof wallpaper with excellent performance, and sequentially comprises an adhesive layer, a paper base layer and an antibacterial waterproof layer,the adhesive layer is located on the lower side of the paper base layer and used for stably bonding the wallpaper and a wall to be decorated together, and the antibacterial waterproof layer is located on the upper side of the paper base layer and has antibacterial, waterproof and mildew-proof effects. A proper amount of hollow silicon dioxide particles are added into the paper base layer, and thehollow silicon dioxide particle structure can form an air hole channel penetrating through the two faces of the paper base layer in the paper base layer. The antibacterial waterproof layer is also provided with micro-nano porous structures which are uniformly distributed, and the porous structures can provide channels for a small amount of gas to penetrate through the wallpaper. Through combination, the air permeability of the wallpaper can be effectively guaranteed, and the bubbling problem of the wallpaper is avoided. In addition, the surface of the antibacterial waterproof layer has uniform micro-nano surface roughness, and an excellent hydrophobic surface structure can be provided. The perfluoropolyether emulsion in the antibacterial waterproof layer can provide excellent hydrophobicand oleophobic performance.

Description

technical field [0001] The invention relates to the field of wallpaper production, in particular to an antibacterial and mildew-resistant wallpaper with excellent performance and a preparation method thereof. Background technique [0002] Wallpaper is a decorative material widely used in modern interior decoration. Compared with traditional paint, wall paint and other interior decoration materials, wallpaper has the advantages of safety and environmental protection, easy construction, and rich and varied color patterns. However, the wallpaper itself also has certain shortcomings, such as not being resistant to wear, easy to be scratched and damaged, easy to be damp and moldy, and easy to breed bacteria. [0003] Compared with fibers, resin materials have better wear resistance, water and moisture resistance. Therefore, people apply a layer of resin glue surface layer on the surface of traditional fiber-based wallpaper to improve the durability, waterproof and moisture resis...
