3D printing zirconia composite ceramic slurry as well as preparation method and application thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to 3D printing zirconia composite ceramic slurry as well as a preparation method and application thereof. The slurry comprises ceramic powder, a surface modifier, a dispersing agent, a cross-linking agent, a diluent and a photoinitiator, the mass of the surface modifier, the mass of the dispersant, the mass of the cross-linking agent, the mass of the diluent and the mass of the photoinitiator are respectively 8%-12%, 2%-6%, 12%-15%, 13%-16% and 3%-6% of the mass of the ceramic powder; the particle size of the ceramic powder is less than or equal to 10 microns; the ceramic powder comprises the following components in percentage by weight: 80%-94% of zirconium oxide, 1.5%-12% of yttrium oxide and 4.5%-15% of aluminum oxide. Due to the specific component proportion, the slurry can maintain low viscosity and support 3D printing forming while having high solid content, the performance of the finally obtained ceramic is not affected, and the obtained ceramic is excellent in mechanical property.
本发明属于陶瓷材料技术领域，具体涉及一种3D打印氧化锆复合陶瓷浆料及其制备方法和应用。该浆料包括陶瓷粉末，表面改性剂，分散剂，交联剂，稀释剂，光引发剂；表面改性剂、分散剂、交联剂、稀释剂、光引发剂的质量分别为陶瓷粉末质量的8％～12％、2％～6％、12％～15％、13％～16％、3％～6％；陶瓷粉末的粒径≤10μm；陶瓷粉末中包含以下重量百分数的组分：氧化锆80％～94％，氧化钇1.5％～12％，氧化铝4.5％～15％。特定的组分配比使该浆料在高固含量的同时，能保持较低的粘度且可以支撑3D打印成型，不会影响最终所得到的陶瓷的性能，所得到的陶瓷力学性能优异。
