Continuous carbon fiber toughened mullite castable based on direct-writing forming 3D printing and preparation method of continuous carbon fiber toughened mullite castable
The invention discloses a continuous carbon fiber toughened mullite castable based on direct-writing forming 3D printing and a preparation method of the continuous carbon fiber toughened mullite castable. The preparation method comprises the following steps: adding 55-75 parts by mass of mullite aggregate, 10-20 parts by mass of alumina micro powder, 2-6 parts by mass of silica powder and 2-6 parts by mass of calcium aluminate cement into a stirrer for mixing and stirring, then adding 0.1-0.5 part by mass of a dispersant, 0.5-1.5 parts by mass of a binder and 10-20 parts by mass of water into the stirrer for mixing and stirring to obtain a mixture, and after the mixture is subjected to spheroidizing, carrying out extrusion molding to obtain a finished product. Printing slurry is obtained; after gas in the printing slurry is exhausted, the printing slurry is loaded into a direct-writing forming 3D printer stock bin, Microsoft 3DBuilder software is used for designing and establishing a porous ceramic filter model, and a continuous fiber toughened mullite castable green body is obtained through printing of a direct-writing forming 3D printer; and naturally drying the green body, and baking to obtain the continuous fiber toughened mullite castable green body. The process is simple, the cost is low, and the prepared castable has the advantages of being high in specific fracture energy, outstanding in breaking strength and the like.
本发明公开了一种基于直写成形3D打印连续碳纤维增韧莫来石质浇注料及其制备方法。将55‑75份质量的莫来石骨料、10‑20份质量的氧化铝微粉、2‑6份质量的硅微粉、2‑6份质量的铝酸钙水泥加入搅拌机混合搅拌，随后向搅拌机中加入0.1‑0.5份质量的分散剂、0.5‑1.5份质量的粘结剂和10‑20份质量的水混合搅拌，得到混合料，将混合料球墨后，得到打印浆料；将打印浆料中的气体排出后，装入直写成形3D打印机料仓中，利用Microsoft 3DBuilder软件设计并建立多孔陶瓷过滤器模型，通过直写成形3D打印机打印得到连续纤维增韧莫来石质浇注料生坯；将生坯自然干燥后进行烘烤，得到连续纤维增韧莫来石质浇注料坯体。本发明工艺简单，成本低廉，所制备的浇注料具有比断裂能高及抗折强度突出等优点。
