Abstract

The invention provides interior wall adornment leather and a preparation method. The interior wall adornment leather comprises base fabric, a foaming layer and a surface layer, wherein an adhesive layer is arranged between the base fabric and the foaming layer; the foaming layer contains foamed water-borne polyurethane resin; the surface layer contains inflaming retardant water-borne polyurethane resin; and the adhesive layer contains adhesive water-borne polyurethane resin. The interior wall adornment leather not only has the advantages of traditional wallpaper sound insulation, heat preservation, gorgeousness and easy adornment, but also has the advantages of safety, environment protection, endurance, ageing resistance and fame resistance, which are incomparable with the traditional wallpaper, and can effectively overcome the defects that the traditional wallpaper is easy to raise margins, does not resist dirt and damp, has poor handfeel, and can not be repaired after wrinkling and the like.
