Lightweight porous material prepared from construction waste and preparation method thereof
The invention discloses a lightweight porous material prepared from construction waste and a preparation method thereof, the raw materials of the lightweight porous material comprise a base material, a reinforcing material and a PVA binder, the base material comprises the construction waste, bauxite, aluminum hydroxide, aluminum fluoride and manganese dioxide; the reinforcing material is prepared from fly ash hollow beads, aluminum hydroxide, aluminum fluoride and vanadium pentoxide with different grain sizes and different mass ratios. The prepared material has the advantages of light weight, porosity, high strength, good thermal stability, acid and alkali corrosion resistance, simple preparation process, easily available raw materials and low cost, is beneficial to industrialization, makes full use of building wastes and power plant solid wastes, can replace increasingly exhausted kaolin porcelain raw materials, and the environment protection is promoted, and resources are effectively saved. Therefore, the method has great economic and social values.
本发明公开了一种利用建筑废弃物制备的轻质多孔材料及其制备方法，其原料由基料、增强料以及PVA粘结剂组成，其中基料组成为建筑废弃物、铝矾土、氢氧化铝、氟化铝、二氧化锰，增强料为不同颗粒级配不同质量配比的粉煤灰空心珠、氢氧化铝、氟化铝、五氧化二钒组成。本发明所制备的材料具有轻质、多孔、高强、热稳定性好、耐酸碱腐蚀，制备工艺简单，原料易得，成本低廉，有利于实现产业化，充分利用了建筑废弃物及电厂固体废弃物，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。
