NOVELTY - A graphene wallpaper comprises a substrate layer, a water permeable layer on the upper surface of the substrate layer, a self-adhesive waterproof layer on the lower surface of the substrate layer and a lower surface of the self-adhesive waterproof layer is provided with a release layer. The substrate layer comprises 40-200 pts. wt. polycarbonate resin, 30-100 pts. wt. phenolic resin, 22-27 pts. wt. corn starch-polyacrylamide copolymer, 1-3 pts. wt. bamboo powder, 1-5 pts. wt. silver nanoparticles, 3-6 pts. wt. titanium dioxide, 5-10 pts. wt. ultrafine talc powder, 3-5 pts. wt. cresyl phosphate, 6-9 pts. wt. dioctyl phthalate, 9-18 pts. wt. graphene, 2-10 pts. wt. antifoaming agent, 6-18 pts. wt. mold removing agent and 3-9 pts. wt. nano titanium dioxide. USE - Graphene wallpaper. ADVANTAGE - A graphene wallpaper has antibacterial property and strong water repellency, and purify the indoor environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene wallpaper, which involves (1) adding a polycarbonate resin, a phenolic resin, a corn starch-polyacrylamide copolymer, a bamboo powder, a silver nano particle, a titanium dioxide, an ultrafine talc powder, a cresol phosphate, dioctyl phthalate, graphene, antifoaming agent, mold removing agent, nano titanium dioxide, mixing and stirring to obtain a mixture (M1), (2) heat treating the mixture (M1) is to form a fusion (M2), (3) extrusion molding and processing the fusion (M2) into a substrate layer, (4) adhering waterproof gas permeable layer to the upper surface of the base material layer, applying a self-adhesive waterproof layer to the lower surface of the base material layer, and then adhering the release layer to the lower surface of the self-adhesive waterproof layer.
