Micro-nano-pore heat insulation refractory material containing calcium hexaluminate and preparation method of micro-nano-pore heat insulation refractory material
The invention belongs to the field of refractory materials, and particularly relates to a calcium hexaluminate-containing micro-nano pore heat insulation refractory material and a preparation method thereof. The heat insulation refractory material is prepared from a basic raw material, an additive and water, the refractory material contains a calcium hexaluminate crystal phase, and the mass percentage of CaO in the chemical composition of the refractory material is 3.5-15%. The micro-nano pore heat insulation refractory material containing calcium hexaluminate is white, sub-white, faint yellow or yellow in appearance; in the refractory material, the pore size distribution of pores is 0.006-250 [mu] m, and the average pore size is 0.1-20 [mu] m. The existence of the micro-nano pore structure in the refractory material ensures that the product has better heat insulation performance under the conditions of low volume density and high strength.
本发明属于耐火材料领域，具体涉及一种含六铝酸钙的微纳孔绝隔热耐火材料及其制备方法。该绝隔热耐火材料由基础原料、添加料和水制成；耐火材料含有六铝酸钙晶相，耐火材料的化学组成中CaO的质量百分含量为3.5～15％。该含六铝酸钙的微纳孔绝隔热耐火材料外观呈白色、亚白色、淡黄色或黄色；耐火材料中，气孔孔径分布在0.006～250μm间，平均孔径0.1～20μm。耐火材料中微纳米尺寸气孔结构的存在保证了制品在低体积密度、高强度下较佳的绝隔热性能。
