Refractory castable and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a refractory castable and a preparation method thereof. The refractory castable comprises the following components in percentage by mass: 50%-80% of aggregate with the particle size of 0.075-3mm, 0-40% of aggregate with the particle size of less than 0.075 mm, 0-20% of powder with the particle size of less than 0.075 mm and 0.1%-20% of a binding agent, a water reducing agent accounting for 0.1-10% of the total weight of the raw materials and water accounting for 5-10% of the total weight of The binding agent is a potassium-based aluminosilicate geopolymer or/and a cesium-based aluminosilicate geopolymer. The refractory castable disclosed by the invention is good in new energy positive electrode material precursor erosion resistance and has excellent high-temperature mechanical property and thermal shock stability, the service life of the refractory material lower body is greatly prolonged, meanwhile, pollution of the new energy positive electrode material in the calcining process can be effectively avoided, and the prepared new energy positive electrode material is high in quality and good in performance.
本发明涉及耐火材料技术领域，具体涉及一种耐火浇注料及其制备方法。按质量百分含量计，耐火浇注料的成分组成为：粒度为0.075～3mm的骨料50%～80%、粒度＜0.075mm的骨料0～40%、粒度＜0.075mm的粉体0～20%、结合剂0.1%～20%；外加占上述原料总重0.1%～10%的减水剂和5%～10%的水；所述结合剂为钾基铝硅酸盐地聚物或/和铯基铝硅酸盐地聚物。本发明耐火浇注料抗新能源正极材料前驱体侵蚀性能好，具有优异的高温力学性能和热震稳定性，极大地提高了耐火材料下体的使用寿命，同时也能够有效避免煅烧过程新能源正极材料的污染，制备的新能源正极材料品质高，性能佳。
