Flame-retardant thermal-insulation light wall material and preparation method thereof

The invention provides a flame-retardant thermal-insulation light wall material, which is prepared from the following raw materials in parts by weight: 30-40 parts of fly ash ceramsite concrete or flyash ceramsite, 60-90 parts of desulfurized gypsum, 20-30 parts of diatomite, 15-20 parts of aluminum oxide, 15-25 parts of phase change energy storage microcapsules, 12-17 parts of bentonite, 10-15 parts of glass fiber, 2-7 parts of an antioxidant, 1-3 parts of an expanding agent, 5-10 parts of a flame retardant, 2-5 parts of a binder and 30-60 parts of water. According to the invention, the rawmaterials are wide in source and low in cost, the preparation method is simple and convenient, the raw materials are energy-saving and environment-friendly, and due to addition of the diatomite and the phase change energy storage microcapsules, the density of the wall material is effectively reduced, the heat preservation and insulation performance and the like are improved, and wide application prospects are achieved. 本发明
