Photocuring molding-based phosphate low-expansion ceramic material and preparation method thereof
The invention is suitable for the technical field of ceramic materials, and relates to a phosphate low-expansion ceramic material based on photocuring molding and a preparation method thereof. Comprising the following steps: uniformly mixing and stirring photosensitive resin, a photoinitiator, a dispersing agent and phosphate powder, and carrying out ball milling to obtain photocuring slurry; printing the photocuring slurry by using a DLP technology to obtain a part blank; the resin is removed by a degreasing process to obtain a photocuring ceramic biscuit, and the photocuring ceramic biscuit is sintered to obtain the phosphate ceramic material which is stable in structure, excellent in mechanical property and low in expansion characteristic. The method has the advantages of being high in forming precision, controllable in process, capable of directly manufacturing ceramics through photocuring and suitable for batch production, is suitable for preparing low-expansion ceramic materials with complex shapes and internal structures, and solves the problem that the ceramics with complex structures are difficult to obtain through a traditional forming process.
本发明适用于陶瓷材料技术领域，涉及一种基于光固化成型的磷酸盐低膨胀陶瓷材料及其制备方法。包括以下步骤：将光敏树脂、光引发剂、分散剂和磷酸盐粉末混合搅拌均匀，球磨，得光固化浆料；使用DLP技术将光固化浆料打印得到零件坯体；通过脱脂工艺将树脂去除，得到光固化陶瓷素坯，经烧结获得结构稳定、力学性能优异，具有低膨胀特性的磷酸盐陶瓷材料。本发明具有成型精度高、工艺可控、能够通过光固化直接制造陶瓷、适于批量生产的优点，适用于制备具有复杂形状及内部结构的低膨胀陶瓷材料，解决了传统成型工艺难以获得具有复杂结构陶瓷的问题。
