Iron-based geopolymer precursor, iron-based geopolymer gel material and preparation methods of iron-based geopolymer precursor and iron-based geopolymer gel material
The invention discloses an iron-based geopolymer precursor, an iron-based geopolymer gel material and a preparation method thereof.The iron-based geopolymer precursor and the iron-based geopolymer gel material are prepared by the steps that firstly, waste iron slag and waste aluminum ash are decomposed, crushed and ground and then added into a salicylic acid solution and a citric acid solution to be fully activated, then the mixture is fully and evenly mixed with a mixed solution of isopropyl alcohol ethyl silicate, and an Al-Fe-Si mixed system solution is formed; the preparation method comprises the following steps: heating in a water bath, drying, calcining and grinding to obtain an iron-based geopolymer precursor, and mixing the iron-based geopolymer precursor with an alkali activator to obtain the iron-based geopolymer gel. The method widens the resource utilization way of the waste steel and aluminum ash, and has important significance on improving the recycling rate of the waste steel and aluminum ash. Meanwhile, the problem that the product performance fluctuates greatly due to uncertainty of raw material components and structures in traditional geopolymer gel prepared from solid waste is solved, the production process is simple, the raw materials are wide and easy to obtain, and the method has good social and economic values and has great application potential in the future.
本发明公开一种铁基地聚物前驱体、铁基地聚物凝胶材料及制备方法，先将废铁渣和废铝灰分解破碎研磨后分别加入水杨酸溶液和柠檬酸溶液中充分活化，再与异丙醇硅酸乙酯的混合液充分混匀，形成Al‑Fe‑Si混合体系溶液，通过水浴加热、烘干、煅烧和研磨后得到铁基地聚物前驱体，将铁基地聚物前驱体与碱激发剂混合制得铁基地聚物凝胶。本发明实现拓宽了废钢铁和废铝灰的资源化利用途径，对提高废钢铁和铝灰回收利用率有重要意义。同时，本发明克服了传统固废制备地聚物凝胶由于原材料组分和结构的不确定性而导致产品性能出现大幅波动的问题，并且生产工艺简单，原料广泛易得，具有良好的社会和经济价值，未来极具应用潜力。
