Energy-saving environment-friendly indoor building material

The invention discloses an energy-saving environment-friendly indoor building material. The material is prepared from, by weight, 6-14 parts of expanded perlite powder, 10-16 parts of diatomaceous earth, 4-8 parts of sepiolite powder, 5-7 parts of low-melting-point glass powder, 4-6 parts of floating beads, 2-4 parts of nano silicon particles, 6-9 parts of hollow fly ash microspheres, 5-7 parts oforganosilicone modified acrylic resin, 4-7 parts of linear low-density polyethylene, 10-15 parts of liquefied waste polyurethane foamed plastic, 1.3-1.7 parts of sticky rice mortar, 0.052-0.102 partof aluminum sulfate, 11-21 parts of phase-change material, 3-7 parts of nano calcium carbonate, 3-9 parts of asbestos wool, 0.5-0.9 part of chitosan and the like. The material has excellent sound absorption and sound insulation performance, corrosion resistance and bending-resistant strength, can greatly reduce the energy consumption for cooling/heating in buildings, and has an energy saving effect far superior to a tradit
