Method for preparing zirconia ceramic material by DLP (Digital Light Processing) technology and zirconia ceramic material
The invention is suitable for the technical field of ceramic materials, and provides a method for preparing a zirconia ceramic material through a DLP technology and the zirconia ceramic material. The method comprises the following steps: adding photosensitive resin, paraffin and a defoaming agent into modified zirconium oxide, and continuously carrying out ball milling treatment to obtain light-cured slurry; printing the photocuring slurry by using a DLP (Digital Light Processing) technology to obtain a part blank, cleaning the part blank, soaking in a degreasing solvent, drying, carrying out thermal degreasing treatment in a degreasing furnace, degreasing at 100-500 DEG C at a heating rate of 0.1-0.5 DEG C/min, heating to 950-1000 DEG C, carrying out heat preservation treatment, sintering at 1450-1500 DEG C for 2-4 hours after degreasing is completed, and cooling to room temperature to obtain a finished product. The zirconia ceramic material is obtained. By optimizing system components and improving the degreasing process, the yield of the high-length-diameter-ratio through-hole thin-wall material prepared through the DLP technology is increased, and the finished product keeps good mechanical performance.
本发明适用于陶瓷材料技术领域，提供了DLP技术制备氧化锆陶瓷材料的方法、氧化锆陶瓷材料。所述方法包括：在改性氧化锆加入光敏树脂、石蜡和消泡剂进行继续球磨处理，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，将零件坯体经清洗后置于脱脂溶剂中进行浸泡处理，再经干燥处理，置于脱脂炉进行热脱脂处理，在100～500℃中使用0.1～0.5℃/min的升温速率，脱脂后升温到950～1000℃进行保温处理，脱脂完成后置于1450～1500℃下烧结2～4h，得氧化锆陶瓷材料。本发明通过优化体系成分以及改进脱脂工艺，提高了DLP技术制备高长径比、通孔薄壁材料的成品率，并使成品保持较好的力学性能。
