Modified auxiliary ceramic powder, preparation method thereof, ceramic slurry and application
The invention belongs to the technical field of photocuring printing, and particularly relates to modified auxiliary ceramic powder, a preparation method thereof, ceramic slurry and application. According to the preparation method of the modified auxiliary ceramic powder, the auxiliary ceramic powder is coated with the aluminum salt sol with specific composition, the absorbance can be remarkably reduced, the modified auxiliary ceramic powder is applied to photo-curing 3D printing forming of a ceramic chopper, the purple light absorption effect of the high-absorbance powder is reduced, more purple light energy is absorbed by photosensitive resin, and the ultraviolet light absorption effect of the high-absorbance powder is improved. The ceramic slurry curing is promoted, and the green body curing depth is improved. Through modification treatment, the high ultraviolet light absorption rate of the auxiliary ceramic powder is improved, and the curing width of the ceramic slurry is reduced, so that the forming precision of the ceramic chopper is improved.
本发明属于光固化打印技术领域，具体涉及一种改性辅助陶瓷粉体及其制备方法、陶瓷浆料和应用。本发明提供的改性辅助陶瓷粉体的制备方法，采用特定组成的铝盐溶胶对辅助陶瓷粉体进行包覆，可显著降低吸光度，应用于陶瓷劈刀的光固化3D打印成型中，使得高吸光度粉体的紫光吸收作用减小，从而更多的紫光能量被光敏树脂吸收，促进了陶瓷浆料固化，提高了坯体固化深度。通过改性处理，改善了辅助陶瓷粉体的高紫外光吸收率，降低了陶瓷浆料的固化宽度，从而提高了陶瓷劈刀的成型精度。
