Method for preparing hierarchical porous ceramic based on thermosensitive emulsion in combination with direct-writing printing forming
The invention discloses a method for preparing hierarchical porous ceramic based on thermosensitive emulsion in combination with direct-writing printing forming, and belongs to the technical field of porous ceramic materials. The method comprises the following steps: ball-milling and mixing ceramic powder and/or ceramic powder oxide sol nanoparticles with epoxy resin and a diluent to obtain a uniform ceramic suspension, adding a surfactant, deionized water and a curing agent, and fully mechanically stirring to obtain the stable thermosensitive emulsion. The heat-sensitive emulsion is used as paste for direct-writing printing forming so as to form a part with a complex shape, and then the hierarchical porous ceramic is obtained through the steps of thermocuring, degreasing and sintering. According to the invention, the thermocuring characteristic of the epoxy resin is utilized, and the characteristics of simplicity, convenience and adjustable pore structure of an emulsion method are combined, so that rapid curing molding is realized, and a novel paste source is provided for a direct-writing printing molding technology, so that the hierarchical porous ceramic with a complex shape is prepared.
本发明公开了一种基于热敏型乳液结合直写打印成型制备多级孔陶瓷的方法，属于多孔陶瓷材料技术领域。该方法将陶瓷粉体和/或陶瓷粉体氧化物溶胶纳米颗粒与环氧树脂、稀释剂进行球磨混合得到均匀陶瓷悬浮液后，加入表面活性剂、去离子水和固化剂，经充分机械搅拌制得稳定的热敏型乳液。将上述热敏性乳液作为直写打印成型的膏体以成型具有复杂形状的零部件，再经热固化、脱脂和烧结步骤得到多级孔陶瓷。本发明利用环氧树脂的热固化特性，结合乳液法简单方便、孔结构可调的特点，实现快速固化成型，并为直写打印成型技术提供新型膏体来源，以制备具有复杂形状的多级孔陶瓷。
