一种陶粒-粉煤灰防火保温材料及其制备方法
摘要：
本发明公开了一种陶粒-粉煤灰防火保温材料及其制备方法，该防火保温材料由陶粒、矿物原料、碱性激发剂、防水剂、减水剂等组成。矿物原料中粉煤灰占70～100wt.％，其他矿物原料含有矿渣、钢渣、石棉尾矿酸浸渣、偏高岭土、循环硫化床底灰、赤泥中的一种或多种；陶粒是矿物原料质量的30～100wt.％；碱性激发剂是矿物原料质量的40～55wt.％；防水剂是矿物原料和玻化微珠总质量的1-3wt.％；减水剂是矿物原料和玻化微珠总质量的1-3wt.％。陶粒、矿物原料、碱性激发剂、防水剂、减水剂充分混合搅拌，可装入模具预制成型，也可浇注成型，在50-90℃下蒸养1～24h。所得防火保温的容重为500～1200kg/m3，抗压强度为2.0-8.0MPa。产品可用作防火材料、保温材料、隔音材料、绝热材料等。
摘要（英）：

The invention discloses a ceramsite-fly ash fireproof thermal insulation material and a preparation method of the ceramsite-fly ash fireproof thermal insulation material. The fireproof thermal insulation material comprises the following raw materials: ceramsite, raw mineral materials, an alkaline exciting agent, a water-proofing agent, a water reducer and the like, wherein the raw mineral materials account for 70-100wt.% of the fly ash; the other raw mineral materials contain one or more of slag, steel slag, asbestos tailings acid slag, metakaolin, circulating fluidized bed bottom ash and red mud; the ceramsite is 30-100wt.% of mass of the raw mineral materials; the alkaline exciting agent is 40-55wt.% of mass of the raw mineral materials; the water-proofing agent is 1-3wt.% of total mass of the raw mineral materials and glass beads; the water reducer is 1-3wt.% of total mass of the raw mineral materials and glass beads; the ceramsite, the raw mineral materials, the alkaline exciting agent, the water-proofing agent and the water reducer are fully mixed and stirred, can be enclosed into a mold to prefabricate and mold, can also be molded in a casting manner, and are steamed and cured at 50-90 DEG C for 1-24 hours; the unit weight of the obtained fireproof thermal insulation material is 500-1200kg/m<3>; and the compressive strength is 2.0-8.0MPa. The product can be used as a fire-proof material, a thermal insulation material, a sound-proof material, an adiabatic material and the like.
