Energy-saving and environment-friendly light wall material and preparation method thereof

The invention provides an energy-saving and environment-friendly light wall material, which is prepared from the following raw materials in parts by weight: 40-60 parts of agricultural wastes containing cellulose, 30-60 parts of Portland cement, 30-50 parts of foamed polystyrene, 15-30 parts of glass fibers, 10-15 parts of basalt, 15-25 parts of slag, 10-15 parts of calcium carbonate, 15-20 partsof diatom ooze, 5-15 parts of aluminum hydroxide, 12-17 parts of phase change energy storage microcapsules, 2-7 parts of a water reducing agent, 3-8 parts of a binder, 1-5 parts of an antioxidant and30-60 parts of water. According to the invention, the raw materials are wide in source and low in cost, the preparation method is simple, most of the wastes are changed into valuable things, and the prepared wall material meets the requirements on mechanical properties such as hardness, durability, tensile strength and the like; and after diatomite is added as an environmentally-friendly raw material, the properties such a
