The invention discloses a novel energy-saving and environment-friendly material. The novel energy-saving and environment-friendly material is prepared from 5 to 10 parts of sepiolite, 5 to 10 parts ofwood fiber, 15 to 20 parts of diatomite, 5 to 10 parts of gypsum, 3 to 5 parts of plant ash, 3 to 5 parts of calcium silicate powder, 3 to 5 parts of silica aluminum powder, 3 to 5 parts of river sand micro powder, 10 to 12 parts of cement, 10 to 14 parts of pore-opening expanded pearlite powder, 3 to 5 parts of sodium polyacrylate, 5 to 8 parts of anti-cracking material, 3 to 6 parts of glazed hollow bead, 5 to 8 parts of the gypsum and 5 to 10 parts of a flame retardant. The energy-saving and environment-friendly material provided by the invention has the advantages of being wide application range and not limited to the external wall insulation of buildings. In addition, the main body structure can be effectively protected, and fire resistance and water resistance are realized; stable room temperature is favorably kept, so that the novel energy-saving and environment-friendly material enables people not to feel hot in summer or cold in winter and has the properties of energy savingand environment friendliness.
