Fly ash-based geopolymer 3D printing material and preparation method thereof
The invention relates to a fly ash-based geopolymer 3D printing material and a preparation method thereof. The fly ash-based geopolymer 3D printing material is prepared from the following raw materials: a base material, quartz sand, a toughening agent, a thickening agent, dispersible latex powder and a composite excitant, wherein the base material comprises the following components in percentage by weight: 80%-90% of fly ash, 5%-10% of mineral powder and 5%-10% of silica fume; wherein the composite excitant is prepared from water glass and NaOH. The geopolymer 3D printing material is preparedfrom the fly ash, the mineral powder and the silica fume, on one hand, the resource utilization way of solid waste is expanded, solid waste reduction, resource utilization and high-value resource utilization are achieved, the problem of pollution caused by the fact that waste is stacked and occupies a site is solved, and a new way is created for protecting the ecological environment; and on the other hand, the fly ash based geopolymer material is innovatively combined with the 3D printing technology, a geopolymer system for 3D printing of buildings is established, and the strategy of nationalintelligent high-end manufacturing and civil engineering sustainable development is met.
本发明涉及一种粉煤灰基地聚合物3D打印材料及其制备方法，包括以下组分的原料：基料、石英砂、增韧剂、增稠剂、可分散乳胶粉和复合激发剂；其中，所述基料包括以下重量百分比的组分：粉煤灰80％～90％、矿粉5％～10％、硅灰5％～10％；所述复合激发剂由水玻璃和NaOH配制而成。本发明利用粉煤灰、矿粉和硅灰制备地聚合物3D打印材料，一方面不仅扩展了固体废弃物的资源化利用途径，也实现了固废减量化、资源化和高价值资源化利用，且解决了废弃物堆放占用场地的污染问题，为保护生态环境创建了新途径；另一方面，创新性地将粉煤灰基地聚合物材料与3D打印技术结合，建立用于3D打印建筑的地聚合物体系，满足国家智能高端制造与土木工程可持续发展的战略。
