Geopolymer powder and preparation method thereof
The invention belongs to the technical field of materials, and particularly relates to geopolymer powder and a preparation method thereof. The preparation method of geopolymer powder in the inventioncomprises the following steps: preparing alumina sol by using water or a water-containing mixed solvent as a solvent, and preparing silica sol by using an organic solvent; mixing the aluminum sol andthe silica sol to obtain mixed sol; carrying out water-bath maintenance on the mixed sol to obtain gel; and sequentially aging, drying, calcining and ball-milling the gel to obtain the geopolymer powder. According to the invention, water is used for completely or partially replacing an organic solvent to prepare Al(OH)3 sol, and the Al(OH)3 sol is mixed with the silica sol to obtain uniform and transparent colloid, so uniform mixing of the alumina sol and the silica sol is realized, and the uniformity and purity of geopolymer powder are improved. According to the preparation method provided bythe invention, water is substantially used for completely or partially replacing an organic solvent in the sol, so production cost is reduced, dissolving time is shortened, and the requirement for green production is better met.
本发明属于材料技术领域，特别涉及一种地质聚合物粉体及其制备方法。本发明提供了一种地质聚合物粉体的制备方法，包括以下步骤：以水或含水混合溶剂为溶剂制备铝溶胶，以有机溶剂制备硅溶胶；将铝溶胶和硅溶胶混合，得到混合溶胶；将所述混合溶胶进行水浴养护，得到凝胶；将所述凝胶依次进行陈化、干燥、煅烧和球磨，得到所述地质聚合物粉体。本发明使用水全部或部分替代有机溶剂，获得了Al(OH)3胶体，并且和硅溶胶混合后得到均一透明的胶体，实现了铝溶胶与硅溶胶的均匀混合，有利于提高地质聚合物粉体的均一性和纯度。本发明提供的制备大大以水完全或部分替代溶胶中的有机溶剂，降低了生产成本、缩短了溶解时间，更加符合绿色生产的要求。
