Manufacture method of sterilization formaldehyde-removing wallpaper

Abstract

The invention discloses a manufacture method of sterilization formaldehyde-removing wallpaper, belonging to the technical field of functional building decoration material manufacture. The manufacture method comprises the following characteristics that: 1, the wallpaper is produced by using the known rolling process productive technology; 2, a wallpaper laminated structure comprises a protective layer and a paper layer according to the top down sequence, the protective layer and the paper layer are adhered by using an adhering agent; 3, design and color patterns of the wallpaper are printed on the paper layer; and 4, a nano titanium dioxide photochemical catalyst is added in the protective layer of the wallpaper, formaldehyde and volatile organic compounds (VOC) are decomposed by using a photocatalysis principle, bacteria are killed and bacterium bodies can be decomposed. The sterilization formaldehyde-removing wallpaper manufactured by using the method has the advantages of simple production process, simple laminated structure and low production cost, and has a function of purifying air, such as sterilizing, removing formaldehyde and the like; the cleanness of the wallpaper can be kept a certain extent, and frequent cleaning is not needed, thus the wallpaper has a certain self-cleaning function. Proved by sterilization experiments, the wallpaper has bacterium killing rate reaching 60 percent when being irradiated by natural light.

Description

technical field [0001] The invention relates to a method for manufacturing sterilized and aldehyde-removing wallpaper, which belongs to the technical field of manufacturing functional building decoration materials. Background technique [0002] Wallpaper, also known as wallpaper, is a specially processed paper used to decorate walls. The birthplace of wallpaper is in Europe, and now it is the most popular in developed countries in Northern Europe, with the best environmental protection and quality, followed by Southeast Asian countries, and the penetration rate of wallpaper in Japan and South Korea is as high as nearly 90%. [0003] Wallpapers are generally composed of protective layers, printing layers, support layers, and paper base layers through adhesives. Due to the extensive use of chemical raw materials such as adhesives, a large amount of formaldehyde volatilizes from the adhesive layers, causing serious pollution to indoor air.

Problems solved by technology

[0003] Wallpapers are generally composed of protective layers, printing layers, support layers, and paper base layers through adhesives. Due to the extensive use of adhesives and other chemical raw materials, a large amount of formaldehyde volatilizes from the adhesive layers, causing serious pollution to indoor air.

Winter and summer are the peak seasons for air conditioners, and they are also the most active seasons for indoor bacteria and viruses. People are very susceptible to various epidemic infectious diseases; people tend to produce a large amount of volatile organic pollution such as formaldehyde, benzene, ammonia, etc. after purchasing new houses for decoration. substances that pose serious risks to the health of residents

Traditional wallpaper occupies a large amount of surface area in the interior decoration space, but it cannot use the surface area to purify the indoor air, which has always been a pity in the field of wallpaper application
