NOVELTY - Aldehyde-free graphene wallpaper and wall cloth comprises aldehyde-free graphene paint or aqueous environmentally-friendly ink. The aldehyde-free graphene paint includes 5-30 pts. deionized water, 0.05-0.5 pts. multifunctional auxiliary agent, 5-50 pts. aqueous resin, 5-30 pts. pigment slurry, 0.05-0.5 pts. dispersant, 0.05-1 pts. waterproof agent, 0.05-0.5 pts. defoamer, 0.05-1 pts. thickener, 0.05-1 pts. fungicide and 0.05-1 pts. anti-formaldehyde additives. The formaldehyde-free adjuvant is a mixture of graphene and nano-titania in a mass ratio of 1:10-10:1. USE - Used as aldehyde-free graphene wallpaper and wall cloth. ADVANTAGE - The wallpaper decomposes harmful substances and has wear-resisting property. DETAILED DESCRIPTION - Aldehyde-free graphene wallpaper and wall cloth comprises aldehyde-free graphene paint or aqueous environmentally-friendly ink. The aldehyde-free graphene paint includes 5-30 pts. deionized water, 0.05-0.5 pts. multifunctional auxiliary agent, 5-50 pts. aqueous resin, 5-30 pts. pigment slurry, 0.05-0.5 pts. dispersant, 0.05-1 pts. waterproof agent, 0.05-0.5 pts. defoamer, 0.05-1 pts. thickener, 0.05-1 pts. fungicide and 0.05-1 pts. anti-formaldehyde additives. The formaldehyde-free adjuvant is a mixture of graphene and nano-titania in a mass ratio of 1:10-10:1. The aqueous environmentally friendly ink comprises 10-30 pts. deionized water, 20-40 pts. aqueous resin, 30-50 pts. pigment paste and 1-5 pts. auxiliary agent. An INDEPENDENT CLAIM is also included for preparing aldehyde-free graphene wallpaper and wall cloth, comprising: (i) preparing aldehyde-free graphene paint or aqueous environmentally-friendly ink coated wallpaper; (ii) preheating the substrate; and (iii) coating the coated wallpaper on a preheated substrate, heating and embossing.
