Biomass material-solid waste-based 3D printing magnesium phosphate cementing material and preparation method thereof
The invention discloses a biomass material-solid waste based 3D printing magnesium phosphate cementing material and a preparation method thereof. The cementing material is prepared from the following components in parts by weight: 5 to 20 parts of biomass material, 30 to 70 parts of dead burned magnesium oxide, 10 to 25 parts of dibasic hydrogen phosphate, 5 to 30 parts of silica fume, 5 to 30 parts of industrial solid waste, 10 to 50 parts of powder filler, 0.2 to 0.4 part of additive and 10 to 24 parts of water, wherein the biomass material is rice hull ash; according to the invention, a large amount of amorphous SiO2 in the silica fume and the rice hull ash is activated by alkali, silicon-aluminum active minerals in industrial solid wastes are activated, and the structural characteristics of the rice hull ash are utilized, so that the interlayer bonding performance, yield performance, thixotropy and constructability of the material are improved, the deformation rate of a printing structure is reduced, and the printing cost is reduced. The prepared cementing material has the advantages of controllable rheological property, easiness in coloring, excellent mechanical property and durability, and has good economic benefits and environmental benefits.
本发明公开了一种生物质材料‑固废基3D打印磷酸镁胶凝材料及其制备方法；所述胶凝材料以重量份计包括以下组分：生物质材料5～20份、重烧氧化镁30～70份、磷酸氢二盐10～25份、硅灰5～30份、工业固体废弃物5～30份、粉末填料10～50份、外加剂0.2～0.4份、水10～24份，所述生物质材料为稻壳灰；本发明通过碱激发硅灰和稻壳灰中大量无定型的SiO2，同时激发工业固废中的硅铝质活性矿物，还利用稻壳灰的结构特性，提高材料的层间粘接性能、屈服性能、触变性及可建造性能，降低打印结构的变形率，制得的胶凝材料具有流变性能可控、易着色，优异力学性能及耐久性的优势，具有良好的经济效益及环境效益。
