Abstract

The invention relates to a making method of a graphene oxide-containing antibiosis and mildew prevention wallpaper, and the antibiosis and mildew prevention wallpaper obtained through the method. The method is characterized in that an antibiosis and mildew prevention agent prepared in the invention is uniformly distributed on a base paper through a sprinkling technology to obtain the antibiosis and mildew prevention wallpaper. Synergism of nanometer graphene oxide, Purpleflower Crotalarla Herb extract and nanometer cerium oxide makes the antibiosis, mildew prevention and peculiar smell removal effects of the wallpaper are substantially improved, the mildew prevention grade is 0 grade, the antibiosis rate to Staphylococcus aureus and Escherichia coli reaches up to 99.9%, and the antibiosis rate to moulds is 100%. The wallpaper does not contain formaldehyde or other toxic substances, so the formaldehyde adsorption effect can reach 98%, improvement of household environment is facilitated, physical and mental pleasant feeling is brought for users, and the use values and the economic benefit of the wallpaper are improved.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of graphene oxide-containing antibacterial and mildew-proof wallpaper. It belongs to the field of new material technology. Background technique [0002] Wallpaper, also known as wallpaper, is a widely used interior decoration material. Because wallpaper has the characteristics of changeable style, various colors, rich patterns, safety and environmental protection, convenient construction, reasonable price, easy to replace and many other interior decoration materials, it is popular in developed countries and regions such as Europe, America, Southeast Asia, Japan and South Korea. gained considerable popularity. With the improvement of people's living standards in our country, wallpaper is widely favored by consumers because of its variety of colors and styles. However, silk wallpapers on the market today are prone to mildew, especially in the Jiangnan area. [0003] ...
