Preparation method of photocuring 3D printing aluminum oxide ceramic paste slurry
The invention discloses a preparation method of photocuring 3D printing aluminum oxide ceramic paste slurry, which comprises the following steps: S1, pretreating aluminum oxide ceramic powder to obtain surface modified aluminum oxide ceramic powder; s2, ball-milling and mixing the surface modified aluminum oxide ceramic powder and prepared photosensitive resin, adding a dispersing agent, a defoaming agent and a photoinitiator, continuously ball-milling, finally adding a rheological agent, stirring, uniformly ball-milling and mixing, and standing for more than 10 hours to obtain ceramic paste slurry. The prepared ceramic paste slurry not only is uniform in dispersion, but also has excellent anti-settling performance and better system stability, and a degreased ceramic green body is not prone to cracking and higher in density.
本发明公开了一种光固化3D打印氧化铝陶瓷膏状浆料的制备方法，包括包括以下步骤：S1：对氧化铝陶瓷粉体进行前处理，得到表面改性氧化铝陶瓷粉体；S2：将表面改性氧化铝陶瓷粉体与配制好的光敏树脂球磨混合后，加入分散剂、消泡剂和光引发剂继续球磨，最后加入流变剂搅拌，经球磨混合均匀，静置10小时以上，从而得到陶瓷膏状浆料。本发明制备得到的陶瓷膏状浆料不仅分散均匀，而且具有优异的抗沉降性能，体系稳定性更优，脱脂后陶瓷坯体不易开裂，致密度更高。
