Problems solved by technology

The utility model patent "Anti-Radiation Wallpaper" (authorized announcement number: CN203080365U) achieves the purpose of anti-radiation by introducing an electromagnetic wave absorbing layer on the wallpaper substrate, but does not specify its shielding effect on Wi-Fi signals
Invention patent "A Preparation Method for Sound-absorbing Wallpaper" (authorized announcement number: CN101831837B) introduces a method of soaking metal powder aqueous solution at room temperature to prepare sound-absorbing wallpaper, but the metal medium only relies on physical adsorption on the surface of the wallpaper Simple interaction, which leads to poor adhesion on the wallpaper surface, easy powder shedding, and ultimately reduces the sound absorption effect
Among them, organic antibacterial agents have disadvantages such as toxicity and poor heat resistance, and natural antibacterial agents also have disadvantages such as poor heat resistance. Although inorganic antibacterial agents have the advantages of long-acting and high heat resistance, they are difficult to disperse and expensive. while limited in application
At present, there are some related patents on antibacterial wallpaper, such as the invention patent "A Humidity Deodorization Antibacterial and Moldproof Wallpaper" (authorized announcement number: CN100526554C), which uses the material containing inorganic antibacterial agents to be added to PVC to make a paste and then coated Get antibacterial wallpaper on the surface of the wallpaper, but this method reduces its environmental protection due to the presence of PVC
In addition, the invention patent "A Method for Making Highly Filled Synthetic Paper-Based New Environmentally Friendly Wallpaper" (Application No.: 201210552587.8) adopts new environmentally friendly high-filled synthetic paper, composite antibacterial agent and water-based paint to obtain PVC-free environmental protection, ecology, and health. Antibacterial wallpaper, but it basically does not have the functions of shielding Wi-Fi signal and sound insulation and noise reduction, which limits its application in some special fields
