The invention discloses non-woven cloth wallpaper. The non-woven cloth wallpaper is prepared from 5-10 parts of polyethylene, 5-10 parts of plant fiber, 30-40 parts of polypropylene, 10-15 parts of polystyrene, 10-15 parts of packing, 20-30 parts of VAE emulsion and 50-60 parts of PVC fibers; the polyethylene, the polypropylene, the polystyrene, the inorganic packing, the VAE emulsion, the plant fiber and the PVC fibers are mixed and then compounded through a calendering method. According to the non-woven cloth wallpaper, the noise reduction coefficient NRC is 0.4-0.5, the permeation volume is 710 L/(m<2>s)- 750 L/(m<2>s), the dispersion coefficient is 1.5%-2.0%, the convention moisture regain is 0.4%-0.5%, and the average water evaporation rate is 25.0%-30.0%. The non-woven cloth wallpaper is good in sound absorption effect, bright in color and low in cost.
