Preparation process of micro-nano cross-scale ceramic slurry
The invention discloses a preparation process of micro-nano cross-scale ceramic slurry. The ceramic slurry is prepared from ceramic powder, a solvent, a dispersing agent, an adhesive, a plasticizer and the like. The ceramic powder comprises micron powder and nano powder; the nano ceramic powder is modified by a coupling agent; the micron ceramic powder is coated with organic resin. By utilizing a nano ceramic powder surface modification technology and a micron powder surface coating technology, on one hand, the activation index of the nano powder is improved, so that the nano powder has relatively strong hydrophobicity, and on the other hand, the buoyancy of the micron ceramic powder is increased through a core-shell structure, so that the hydrophobicity of the nano powder is improved. Therefore, the problem of high settling rate of micron particles in a ceramic slurry system is solved. The prepared micro-nano cross-scale ceramic slurry can be stored for a long time in a room temperature environment, and a solid foundation is laid for tape casting and stable quality of a substrate.
本发明公开了一种微纳跨尺度陶瓷浆料的制备工艺，所述陶瓷浆料由陶瓷粉、溶剂、分散剂、粘接剂、增塑剂等组成；所述陶瓷粉包括微米粉体和纳米粉体；所述纳米陶瓷粉体经偶联剂改性处理；所述微米陶瓷粉体经有机树脂包覆处理。本发明利用纳米陶瓷粉体表面改性技术以及微米粉体表面包覆技术，一方面提高了纳米粉体的活化指数，使得纳米粉体具有较强的疏水性，另一方面通过核壳结构来增大微米陶瓷粉体的浮力，从而改善陶瓷浆料体系中微米颗粒沉降速率快的问题。本发明制备的微纳跨尺度陶瓷浆料可在室温环境下实现长时间的存储，为流延成型及基板的质量稳定奠定坚实的基础。
