Geopolymer microsphere with hollow shell-shell structure as well as preparation method and application of geopolymer microsphere
The invention discloses geopolymer microspheres with a hollow shell-shell structure as well as a preparation method and application of the geopolymer microspheres. The preparation method comprises the following steps: mixing a gel material with alkali-activated activity or acid-activated activity, an activator, water and a solvent immiscible with water into uniform slurry according to different proportions by adopting a dispersion-suspension-curing method; the geopolymer raw materials used in the method are wide in source and belong to solid waste utilization, the method is simple in preparation process operation, low in energy consumption and environmentally friendly, the prepared hollow microspheres are good in sphericity degree, and the method is suitable for large-scale production. According to the present invention, the prepared hollow microspheres have characteristics of large pore volume, large specific surface area, high efficiency and controllable particle size, can be used as a novel adsorption material and a novel catalytic material, and have excellent characteristics of high strength, high temperature resistance, corrosion resistance, stable chemical property and the like, and the method has great advantages and application prospects in the fields of hollow microsphere preparation, adsorption, catalysis and the like.
本发明公开了一种空心壳‑壳结构地聚物微球及其制备方法、应用，采用分散‑悬浮‑固化法将具有碱激发活性或酸激发活性的凝胶材料、激发剂、水和与水不互溶的溶剂按照不同的比例混合成均匀浆料，然后倒入高速分散的热硅油中使其固化成球，再经过养护、抽滤、清洗、干燥及煅烧后得到不同粒径的空心微球，本发明使用的地聚物原料来源广泛，属于固废利用，制备流程操作简单、能耗低、绿色环保，且制备的空心微球的球形度好，具有较大的孔体积和比表面积，效率高，粒径可控，还可以作为一种新型的吸附材料和催化材料，具有强度高、耐高温、耐腐蚀、化学性质稳定等优异特性，该方法在空心微球制备方面及吸附和催化等领域具有很大的优势和应用前景。
