Graphene enhanced photocuring 3D printing silicon-based ceramic as well as preparation method and application thereof
The invention provides a graphene enhanced photocuring 3D printing silicon-based ceramic, which is prepared from photosensitive resin and silicon-based composite ceramic powder, the silicon-based composite ceramic powder is composed of a matrix material, a mineralization modifier and graphene, and the photosensitive resin is composed of an initiator, a dispersant and a crosslinking auxiliary agent. The preparation method comprises the following steps: mixing and ball-milling the photosensitive resin and the silicon-based composite ceramic powder, printing in a ceramic 3D printer, degreasing, and sintering. The method can be used for ceramic core precision casting. The forming precision of the photocuring additive manufacturing silicon-based ceramic core can be effectively adjusted, sintering shrinkage can be inhibited, generation of interlayer cracks in the degreasing and sintering process can be avoided, and the silicon-based ceramic core with excellent comprehensive performance can be obtained.
本发明提供了一种石墨烯增强光固化3D打印硅基陶瓷，由光敏树脂、硅基复合陶瓷粉体制成，硅基复合陶瓷粉体由基体材料、矿化改性剂、石墨烯组成，光敏树脂由引发剂、分散剂和交联助剂组成。还提供了制备方法:将光敏树脂和硅基复合陶瓷粉体混合球磨后，置于陶瓷3D打印机中打印，然后进行脱脂处理、烧结而成。能用于陶瓷型芯精密铸造。本发明可有效调节光固化增材制造硅基陶瓷型芯成形精度并抑制烧结收缩，可避免脱脂烧结过程中层间裂纹的产生，可获得综合性能优异的硅基陶瓷型芯。
