The invention provides a multi-stage pore mullite light heat-insulating brick. The multi-stage pore mullite light heat-insulating brick is prepared from the following raw materials in parts by mass: 30-50 parts of fly ash, 10-20 parts of aluminum oxide, 10-20 parts of kyanite tailings, 5-10 parts of sawdust, 5-10 parts of aluminum hydroxide and 5-15 parts of a polyvinyl alcohol solution. The fly ash and the kyanite tailings are adopted as main raw materials to prepare the mullite light heat insulation material, industrial waste can be fully recycled, environmental pollution caused by direct stacking or landfill of the fly ash and the kyanite tailings is avoided, and the method has the advantages of resource saving, environment friendliness, low production cost, suitability for industrial production and the like.
本发明提供一种多级孔隙莫来石轻质隔热砖，由以下质量份的原料制得：30～50份粉煤灰、10～20份氧化铝、10～20份蓝晶石尾矿、5～10份锯末、5～10份氢氧化铝和5～15份聚乙烯醇溶液。本发明采用粉煤灰和蓝晶石尾矿作为主要原料制备莫来石轻质隔热材料，可以实现工业废弃物的充分回收利用，避免因粉煤灰和蓝晶石尾矿直接堆放或填埋而对环境产生污染，具有节约资源、环境友好、生产成本低、适合工业化生产等优点。
