Ceramic product based on binder jet printing technology, preparation method and ceramic mobile phone backboard
The invention discloses a ceramic product based on a binder jet printing technology, a preparation method and a ceramic mobile phone backboard, and relates to the technical field of ceramic additive manufacturing. According to the preparation method provided by the invention, during granulation, the curing agent, the ceramic powder and the forming agent are granulated together, the obtained ceramic particles are used for binder jet printing, the curing agent in the ceramic particles can uniformly react with the printing binder to realize blank forming and curing, and the problems that the printing binder is incompatible with the forming agent, and the forming agent is not compatible with the printing binder are solved. And a green body is difficult to cure. The method further comprises the step of carrying out infiltration treatment on the degreased green body by adopting a ceramic suspension, so that the relative density of the sintered ceramic part is improved. The preparation method provided by the invention effectively solves the problems of low flowability, difficult solidification and low density of powder in the BJ technology, expands the application scene of the BJ technology, and ensures the mechanical properties of ceramic products. By adopting the preparation method disclosed by the invention, the high-complexity and high-performance ceramic product or mobile phone backboard can be prepared.
本发明公开了一种基于粘结剂喷射打印技术的陶瓷制品、制备方法及陶瓷手机背板，涉及陶瓷增材制造技术领域。本发明提供的制备方法在造粒时将固化剂与陶瓷粉体、成型剂一同造粒，得到的陶瓷颗粒用于粘结剂喷射打印，陶瓷颗粒中的固化剂能够均匀地与打印粘结剂发生反应实现坯体成型固化，解决了打印粘结剂与成型剂不兼容，坯体难固化的问题；该方法还包括对脱脂后的坯体采用陶瓷悬浮液进行浸渗处理，提高烧结后陶瓷件的相对密度。本发明的制备方法有效解决了BJ技术中粉体的流动性低、难以固化和致密度较低的问题，扩展了BJ技术的适用场景，保证了陶瓷制品的力学性能。采用本发明的制备方法能够制备出高复杂度、高性能的陶瓷制品或手机背板。
