Lightweight refractory material prepared from construction wastes and preparation method thereof
The invention discloses a lightweight refractory material prepared from construction waste and a preparation method thereof, the raw materials of the lightweight refractory material comprise a base material and an auxiliary material, the base material comprises 60-80 wt% of construction waste, 5-30 wt% of mineral raw material bauxite, 5-30 wt% of industrial raw material aluminum hydroxide, and 3 wt% of additive aluminum fluoride; and the auxiliary materials comprise 20-40wt% of fly ash hollow beads with different particle sizes and different mass ratios and 5-9wt% of PVA binder. The material prepared by the invention has the advantages of light weight, high strength, good thermal shock resistance, simple preparation process, easily available raw materials, low cost and facilitation of industrialization, fully utilizes building wastes and power plant solid wastes, greatly reduces the use of high-quality mineral raw materials, not only can replace increasingly exhausted kaolin porcelain raw materials, but also the environment protection is promoted, and resources are effectively saved. Therefore, the method has great economic and social values.
本发明公开一种利用建筑废弃物制备的轻质耐火材料及其制备方法，其原料由基料和辅料组成，基料组成为建筑废弃物60～80wt％、矿物原料铝矾土5～30wt％、工业原料氢氧化铝5～30wt％、添加剂氟化铝3wt％，辅料为不同颗粒级配不同质量配比的粉煤灰空心珠20～40wt％、PVA粘结剂5～9wt％。本发明所制备的材料具有轻质、高强、抗热震性能好，制备工艺简单，原料易得，成本低廉，有利于实现产业化，本发明充分利用了建筑废弃物及电厂固体废弃物，大大降低了优质矿物原料的使用，不仅可以替代正日益枯竭的高岭土类瓷质原料，还对环境的保护起到了促进作用，有效地节约了资源。因此本发明具有较大的经济和社会价值。
