Solid-waste-based high-toughness geopolymer for 3D printing and preparation method of solid-waste-based high-toughness geopolymer
The invention relates to a solid waste-based high-toughness geopolymer for 3D printing and a preparation method thereof. The geopolymer is prepared from the following components in parts by mass: 100 parts of an aluminosilicate precursor material, 13.5 to 16.5 parts of a composite solid activator, 1.0 to 4.0 parts of a thixotropic agent, 120 to 140 parts of fine aggregate, 0.60 to 1.20 parts of fiber and 36 to 44 parts of water, the method specifically comprises the following steps: soaking fibers in a dispersion liquid; mixing and stirring to obtain a geopolymer composite dry blend; mixing and stirring the geopolymer composite dry blend and water to obtain geopolymer slurry; and performing 3D printing on the geopolymer slurry to obtain a 3D printing geopolymer entity. Compared with the prior art, the problems that a bi-component geopolymer is poor in toughness and a strongly alkaline liquid exciting agent is difficult to transport, store and mix are solved, and the problem that the printability in the 3D printing technology is degraded due to slurry rheological property weakening caused by geopolymer fiber doping is solved.
本发明涉及一种用于3D打印的固废基高韧性地聚合物及其制备方法,该地聚合物各组分以质量份数计分别为铝硅酸盐前驱体材料100份、复合固体激发剂13.5‑16.5份、触变剂1.0‑4.0份、细骨料120‑140份、纤维0.60‑1.20份和水36‑44份;该方法具体为:将纤维于分散液中浸泡;混合搅拌得到地聚合物复合干混料;将地聚合物复合干混料和水混合搅拌,得到地聚合物浆体;将地聚合物浆体3D打印,得到3D打印地聚合物实体。与现有技术相比,本发明克服双组分地聚合物的韧性差以及强碱性液体激发剂运输、储备和混合困难问题,解决地聚合物纤维掺入引起的浆体流变性能弱化进而引发在3D打印技术中的可打印性劣化问题。
