Preparation method of tough bionic structure ceramic material for fused deposition 3D printing
The invention discloses a preparation method of a tough bionic structure ceramic material for fused deposition 3D printing, and belongs to the technical field of additive manufacturing. Graphene and an ionic polymer are modified on the surface of flaky ceramic powder, so that the agglomeration and accumulation tendency among the flaky ceramic powder can be inhibited, and the toughness of the ceramic material is improved; the dispersity of the flaky ceramic powder among the alkane printing bonding aids can also be improved, so that the flaky ceramic powder can be oriented under the action of an external field; and meanwhile, graphene introduced in situ is beneficial to improving the strength and toughness of the flaky ceramic powder, the structural integrity of the raw materials in the processing process and the obdurability of the finally sintered ceramic are improved, and the problem that complex components are not easy to prepare in existing ceramic fused deposition 3D printing is solved.
本发明公开了用于熔融沉积3D打印的韧性仿生结构陶瓷材料制备方法，属于增材制造的技术领域，通过在片状陶瓷粉料的表面修饰石墨烯和离子聚合物，不仅可以抑制片状陶瓷粉料之间的团聚和堆积倾向，也可以改善片状陶瓷粉料在烷烃类打印粘结助剂之间的分散性，从而有利于使片状陶瓷粉料在外场作用下取向；同时原位引入的石墨烯有助于提升片状陶瓷粉料的强度和韧性，提升原料在加工过程中的结构完整性和最后烧结陶瓷的强韧性，克服了现有的陶瓷熔融沉积3D打印中的不易制备复杂构件的难题。
