The invention belongs to the technical field of refractory materials, and particularly relates to a special corundum castable for a circulating fluidized bed boiler and a preparation method thereof, the castable comprises the following raw materials: 20-50 parts of 3-5mm white corundum particles, 5-10 parts of alpha-alumina micro powder, 2-5 parts of silica fume, 1-5 parts of a binder, 0.5-1 part of a water reducer, and 1-5 parts of a SiC-ZrB2/chitosan quaternary ammonium salt modified graphene composite material. The material formed by the obtained castable has the properties of low apparent porosity, good mechanical properties, high corrosion resistance and the like.
本发明属于耐火材料技术领域，具体涉及一种循环流化床锅炉专用刚玉浇注料及其制备方法，其中，浇注料的原料包括：3～5mm的白刚玉颗粒20～50份、α‑氧化铝微粉5～10份、微硅粉2～5份、粘结剂1～5份、减水剂0.5～1份、SiC‑ZrB2/壳聚糖季铵盐改性石墨烯复合材料1～5份。本发明所得浇注料成型后的材料具有显气孔率低、机械力学性能好、耐腐蚀性强等性能。
