Photocuring 3D printing ceramic slurry as well as preparation method and application thereof
The invention relates to the technical field of 3D printing materials, and discloses photocuring 3D printing ceramic slurry as well as a preparation method and application thereof. The ceramic slurry comprises ceramic powder; wherein the ceramic powder comprises the following components in percentage by mass: 5-25% of ceramic powder with the average particle size of 4 mu m, 10-40% of ceramic powder with the average particle size of 1 mu m and 40-80% of ceramic powder with the average particle size of 0.2 mu m. Mixing a part of the dispersing agent with the ceramic powder, and reacting to obtain modified ceramic powder; mixing the modified ceramic powder with an active diluent, an active monomer and a photoinitiator, and performing first ball milling to obtain primary ceramic slurry; and mixing the primary ceramic slurry with the residual dispersant, and carrying out second ball milling to obtain the ceramic slurry. The photocuring 3D printing ceramic slurry provided by the invention has the characteristics of low viscosity and high solid content, is good in fluidity, can efficiently form a high-precision ceramic part, and successfully prepares a ceramic part with a complex microporous structure.
本发明涉及3D打印材料技术领域，公开了一种光固化3D打印陶瓷浆料及其制备方法和应用。所述陶瓷浆料包括陶瓷粉末；其中，所述陶瓷粉末按质量百分比计包括以下组分：平均粒径为4μm的陶瓷粉体5‑25％、平均粒径为1μm的陶瓷粉体10‑40％和平均粒径为0.2μm的陶瓷粉体40‑80％。将部分分散剂与陶瓷粉末混合后进行反应得到改性陶瓷粉末；将改性陶瓷粉末与活性稀释剂、活性单体和光引发剂混合后进行第一球磨，得到初级陶瓷浆料；将初级陶瓷浆料与剩余分散剂混合后进行第二球磨，得到所述陶瓷浆料。本发明提供的光固化3D打印陶瓷浆料具有低粘度、高固含量的特点，流动性好，能够高效成形高精度陶瓷制件，成功制备具有复杂微孔结构的陶瓷制件。
