Photo-curing formed high-solid-content silicon nitride ceramic and preparation method and application thereof
The embodiment of the invention discloses photo-curing formed high-solid-content silicon nitride ceramic as well as a preparation method and application thereof, and relates to the technical field of ceramic materials. The preparation method comprises the steps that a prepared base layer resin mixed solution is placed in a 3D printer trough, and a base layer model is printed; the prepared high-solid-content silicon nitride ceramic slurry is placed in the 3D printer trough, and a model ceramic layer is printed under auxiliary leveling of a scraper; and after forming is finished, the cured base resin and the ceramic layer are cleaned away from a printing platform through a blade, the base resin is removed through a ceramic degreasing technology, and a final light-cured ceramic biscuit is obtained. According to the method for photo-curing the high-solid-content silicon nitride ceramic slurry, the problem that the high-solid-content silicon nitride ceramic slurry is low in forming success rate due to high viscosity and low curing depth can be effectively solved, and meanwhile, the printing method can reduce the forming defect of photo-curing high-solid-content silicon nitride and improve the printing precision.
本发明实施例公开了一种光固化成型的高固相含量氮化硅陶瓷及其制备方法和应用，涉及陶瓷材料技术领域。其中，制备方法包括：将配置好的基层树脂混合液置于3D打印机料槽中，并打印基层模型；将配置好的高固相含量氮化硅陶瓷浆料置于3D打印料槽中，在刮刀的辅助流平下，打印模型陶瓷层；成型结束后，利用刀片将固化后的基层树脂和陶瓷层从打印平台上清理掉，并利用陶瓷脱脂工艺将基层树脂去除，得到最终的光固化陶瓷素坯。本申请提供一种光固化高固相含量氮化硅陶瓷浆料的方法，能够有效解决高固相氮化硅陶瓷浆料由于粘度高、固化深度浅导致成型成功率低的问题，该打印方法同时能够减少光固化高固相氮化硅成型缺陷，提高打印精度。
