Preparation method of ceramic paste for direct ink writing 3D printing
The invention discloses a preparation method of ceramic paste for direct ink writing 3D printing. The preparation method comprises the following steps: accurately weighing raw powder, a solvent and adispersing agent according to the chemical composition of ceramic, and sequentially carrying out ball-milling mixing, drying, grinding, low-temperature calcining and graded screening to obtain ceramicprecursor powder; separately weighing a water-soluble thickener and high-purity deionized water in proportion, and conducting sufficient stirring and uniform mixing to obtain polymer gel; separatelyweighing the ceramic precursor powder and the polymer gel in proportion, conducting sufficient stirring and uniform mixing, and then putting the uniformly mixed ceramic paste into a centrifugal vacuumstirrer for vacuum defoaming treatment so as to obtain the high-density ceramic paste. The prepared ceramic paste has extremely high solid content and shear thinning performance and a wide viscoelasticity controllable interval, so the ceramic paste shows good rheological properties; and the preparation method is simple in steps, controllable in conditions and easy to promote.
本发明公开了一种浆料直写成型3D打印用陶瓷膏体的制备方法，步骤是：根据陶瓷的化学组成精确称量原料粉体、溶剂、分散剂，然后依次经过球磨混合、烘干、研磨、低温煅烧以及分级过筛步骤得到陶瓷前驱体粉体；按比例分别称量水溶性增稠剂与高纯去离子水，并进行充分搅拌混合均匀得到高分子凝胶体；按按比例分别称量陶瓷前驱体粉体和高分子凝胶体，并充分搅拌混合均匀，然后将混匀的陶瓷膏体置于离心真空搅拌机中进行真空脱泡处理，得到高致密的陶瓷膏体。本发明制备的陶瓷膏体具有极高的固含量和剪切变稀性能以及宽的粘弹性可控区间，显示出该陶瓷膏体具有良好的流变性能，制备步骤简单，条件可控，易于推广。
