Zirconia ceramic slurry, preparation method and application thereof, 3D printing zirconia ceramic and application thereof
The invention provides zirconia ceramic slurry, a preparation method and application thereof, 3D printing zirconia ceramic and application thereof, and relates to the technical field of additive materials. The zirconia ceramic slurry provided by the invention comprises modified zirconia powder, a resin premixed solution, an additive, a photoinitiator and a thermal initiator, the modified zirconium oxide powder is obtained by modifying yttrium oxide doped zirconium oxide powder with one or more modifiers of methacrylic acid, 3-(methacryloyloxy) propyltrimethoxysilane and stearic acid; the resin premixed liquid comprises the following components: an acrylate oligomer and an active diluent. The zirconia ceramic slurry provided by the invention is high in solid content and low in viscosity, and is suitable for various types of DLP printers of ultraviolet light and visible light, and the 3D printing zirconia ceramic obtained through 3D printing, photocuring, thermocuring, degreasing and sintering is high in density and excellent in mechanical property, and can meet the mechanical property standard of dental prostheses.
本发明提供了一种氧化锆陶瓷浆料及其制备方法和应用、3D打印氧化锆陶瓷及其应用，涉及增材技术领域。本发明提供的氧化锆陶瓷浆料的组成包括改性氧化锆粉、树脂预混液、添加剂、光引发剂和热引发剂；所述改性氧化锆粉由氧化钇掺杂氧化锆粉经甲基丙烯酸、3‑(异丁烯酰氧)丙基三甲氧基硅烷和硬脂酸中的一种或几种改性剂改性后得到；所述树脂预混液的组分包括丙烯酸酯类低聚物、活性稀释剂。本发明提供的氧化锆陶瓷浆料固含量高且粘度低，适用于紫外光、可见光的多种型号的DLP打印机，经3D打印、光固化、热固化、脱脂和烧结得到的3D打印氧化锆陶瓷密度高、力学性能优异，能够满足牙科修复体的力学性能标准。
