Lightweight porous mullite ceramic and direct-writing 3D printing preparation method thereof
The invention belongs to the related technical field of inorganic nonmetal ceramic preparation and discloses a lightweight porous mullite ceramic and a direct-writing 3D printing preparation method thereof. The method comprises the following steps: (1) mixing and stirring kaolin powder and pore-forming agent powder to obtain uniformly mixed powder, adding a plasticizer and a solvent into the mixedpowder, stirring to obtain ceramic paste, and degassing the ceramic paste; (2) taking the ceramic paste as a raw material, and printing a porous ceramic green body by adopting a direct-writing 3D printer; and (3) drying and sintering the porous ceramic green body to obtain the lightweight porous mullite ceramic with a specific shape structure. The method is low in cost, high in forming speed andsimple in preparation process, is beneficial to the solution of the recycling problem of waste coal series kaolinite, and has a good application prospect in the fields of chemical engineering and thelike.
本发明属于无机非金属陶瓷制备相关技术领域，其公开了一种轻质多孔莫来石陶瓷及其直写3D打印制备方法，所述方法包括以下步骤：(1)将高岭土粉末及造孔剂粉末混合搅拌以得到混合均匀的混合粉体，再将增塑剂和溶剂加入所述混合粉体中并进行搅拌以得到陶瓷膏料，进而对所述陶瓷膏料进行除气；(2)以所述陶瓷膏料为原料，采用直写3D打印机打印多孔陶瓷坯体(3)将所述多孔陶瓷坯体进行干燥及烧结以得到具有具体形状结构的轻质多孔莫来石陶瓷。本发明成本较低，成形速度较快，制备工艺简单，有利于解决废弃煤系高岭土的再利用问题，在化工等领域具有较好的应用前景。
