Mullite composite castable with enhanced anti-seismic property and preparation method of mullite composite castable
The invention discloses a mullite composite castable capable of enhancing anti-seismic property. The mullite composite castable is prepared from the following components in percentage by mass: 18 to 20 percent of andalusite aggregate, 35 to 50 percent of corundum aggregate, 4 to 5 percent of micro powder, 7.5 to 8.5 percent of silica sol, 0.5 to 1.2 percent of cold-proof agent, 0.8 to 1.0 percent of steel fiber, 0.4 to 0.6 percent of silicon carbide nano particles and the balance of porous mullite, the preparation method of the mullite composite castable comprises the following steps: S1, mixing the raw materials; and S2, molding and firing. The mullite composite castable disclosed by the invention is compounded with corundum, so that the mullite composite castable has good high-temperature strength, thermal shock resistance and chemical stability; and in the preparation process, the porous mullite is mixed step by step according to pore diameters, and the vacuum degree is synchronously adjusted, so that the density and the overall anti-seismic property of the composite castable are improved.
本发明公开了一种增强抗震性能的莫来石复合浇注料，按质量比计包括：18～20％的红柱石骨料、35～50％的刚玉骨料、4～5％的微粉、7.5～8.5％的硅溶胶、0.5～1.2％的防寒剂，0.8～1.0％的钢纤维、0.4～0.6％的碳化硅纳米颗粒以及余量的多孔莫来石；上述莫来石复合浇注料的制备方法包括S1、原料混合和S2、成型烧制；本发明莫来石复合浇注料通过与刚玉复合，具有良好的高温强度、抗热震性和化学稳定性；并在制备过程中通过分孔径分步混合多孔莫来石，同步调节真空度，提高复合浇注料的密度以及整体抗震性能。
