Preparation method of anorthite-based porous lightweight refractory material
The invention belongs to the technical field of porous lightweight refractory materials, and particularly relates to a preparation method of an anorthite-based porous lightweight refractory material, the preparation method comprises the following steps: taking a tetramethylammonium hydroxide aqueous solution in which a foam stabilizer polyvinyl alcohol is dissolved as an alkaline activator; taking a mixture of metakaolin, calcium oxide and silicon dioxide which are proportioned according to the chemical components of the calcium aluminosilicate as raw material powder, fully stirring and reacting an alkaline exciting agent and the raw material powder, and then stirring at a high speed by taking sodium dodecyl benzene sulfonate as a foaming agent/initiator to prepare a porous calcium aluminosilicate-based geopolymer blank; and finally, firing the dried green body at high temperature to obtain the anorthite-based porous lightweight refractory material. According to the preparation method, metakaolin is taken as a main raw material source, the raw material source is wide, the whole preparation process is pollution-free and waste-free, the cost is relatively low, and the industrial popularization value is relatively high.
本发明属于多孔轻质耐火材料技术领域，具体涉及一种钙长石基多孔轻质耐火材料的制备方法，该制备方法以溶有稳泡剂聚乙烯醇的四甲基氢氧化铵水溶液作为碱性激发剂，将按钙长石化学组分配比的偏高岭土、氧化钙和二氧化硅混料作为原料粉体，待碱性激发剂与原料粉体充分搅拌反应后，再将十二烷基苯磺酸钠作为发泡剂/引发剂高速搅拌制备出多孔的钙铝硅酸盐基地质聚合物坯体，最后将受过干燥处理的坯体在高温下烧制成钙长石基多孔轻质耐火材料。本发明制备方法以偏高岭土为主要原料来源，原料来源广泛、制备过程全程无污染、无浪费、成本较为低廉，有较高的工业推广价值。
