The invention relates to a building material, in particular to a new wall material. The new wall material comprises a rubber material and an additive promoter, and is characterized in that the rubbermaterial comprises 20 to 30% of plastic, 50 to 70% of silicon micro-ash and 10 to 20% of cement in percentage by weight; and the additive promoter comprises 15 to 25% of maleic anhydride modified polypropylene, 2 to 4% of aluminum powder paste, 1 to 2% of aluminum powder, 8 to 12% of phenolic resin, 2 to 4% of bisstearamide, 8 to 12% of magnesium hydroxide, 45 to 55% of water, 1 to 2% of stone-like coating, 1 to 2% of silicone oil and 1 to 2% of pigment in percentage by weight. The wall material prepared by the invention is light in weight and easy to move and can change the use appearance ofthe wall material according to corresponding design requirements during the use process, thereby being convenient to use and good in use appearance.
