Foaming ceramic prepared from tailings rich in calcium, magnesium and molybdenum and preparation method of foaming ceramic
The invention discloses foamed ceramic prepared from calcium-magnesium-rich molybdenum tailings and a preparation method, raw materials of the foamed ceramic comprise a base material and a foaming agent, the base material comprises the following components by mass: 50-70% of molybdenum tailings, 15-25% of fly ash, 10-25% of kaolin, 5-15% of silicon tailings, and 2-8% of alumina; the mass of the foaming agent is 0.4-1.0% of the mass of the base material; the foamed ceramic is based on a Si-Al-Mg-Ca component system, the high utilization rate of the molybdenum tailings is achieved, meanwhile, other solid waste materials in the region are fully utilized, the utilization rate of the solid waste materials in the foamed ceramic is further increased, the utilization rate of the molybdenum tailings is not lower than 50%, the proportion of all solid waste materials is not lower than 70%, and the foamed ceramic is suitable for being used in the field of building materials. The foamed ceramic has a uniform and dense pore structure.
本发明公开了一种利用富钙镁钼尾矿制备的发泡陶瓷及制备方法，其原材料由基料以及发泡剂组成，其中，基料按质量百分比计，组成如下：钼尾矿50‑70％，粉煤灰15‑25％，高岭土10‑25％，硅尾矿5‑15％，氧化铝2‑8％；所述发泡剂的质量为基料质量的0.4‑1.0％；本发明所提供的发泡陶瓷基于Si‑Al‑Mg‑Ca组分体系，不仅实现了钼尾矿的高利用率，同时充分利用该地区其他固废材料，进一步提高固废材料在发泡陶瓷中的利用率，本发明中钼尾矿利用率不低于50％，全固废材料占比不低于70％，发泡陶瓷要具备均匀且绵密的孔结构。
