NOVELTY - Preparing building decoration material comprises e.g. crushing base material, polished brick waste, polishing glaze waste, graphene powder, marble waste, quartz stone waste, quartz sand, glass waste and toner, mixing with water-soluble resin to obtain processed powder, and adding into the mold, carrying out high temperature steam treatment for 10-15 minutes, and then extruding in molding machine to obtain final product. USE - The method is useful for preparing building decoration material (claimed). ADVANTAGE - The method has high structure intensity of the material processed by the method, and adopting waste or natural raw material, rich material and no pollution. DETAILED DESCRIPTION - Preparing building decoration material comprises (i) crushing base material, polished brick waste, polishing glaze waste, graphene powder, marble waste, quartz stone waste, quartz sand, glass waste and toner to obtain base material, (ii) taking stainless steel utensils mold, attaching to the surface of the mold layer of polyethylene film, (iii) fixing the second mold in the mold on the relative inner side of the mold evenly with a filament, (iv) mixing the base material prepared in step (i) with water-soluble resin to obtain processed powder, and (v) adding the processed powder obtained in step (iv) into step (ii) of the mold, carrying out high temperature steam treatment for 10-15 minutes, and then extruding in molding machine to obtain final product.
