High-uniformity emulsified ceramic slurry and preparation method thereof
The preparation method comprises the following steps: S1, preparation of a dispersing agent: mixing polyacrylic acid and a collagen polypeptide aqueous solution according to a ratio of (10-15): 1, adding ultrapure water with the same volume as the polyacrylic acid and the collagen polypeptide aqueous solution as a solvent, and uniformly stirring to obtain the dispersing agent; s2, preparing ceramic slurry: weighing the ceramic powder according to a stoichiometric ratio, adding a dispersing agent accounting for 0.2-1.0 wt% of the ceramic powder, adding ultrapure water to adjust the volume solid content of the ceramic slurry to 14-18 vol.%, and then performing ball milling to obtain emulsified ceramic slurry; s3, post-treatment of the ceramic slurry: adding polypropylene glycol accounting for 1.0-1.5 wt.% of the ceramic powder into the emulsified ceramic slurry, then removing water, and stirring to obtain the final ceramic slurry. According to the preparation method, long-acting stable multi-bubble emulsified ceramic slurry can be directly prepared, the preparation problems that ceramic slurry is difficult to store, poor in uniformity, poor in stability and the like are solved, the preparation process is simple, and industrial production is easy.
本发明公开了一种高均匀性乳化型陶瓷浆料及其制备方法，包括以下步骤：S1分散剂配置：将聚丙烯酸与胶原多肽水溶液按10～15：1的比例混合，加入等体积的超纯水作为溶剂，搅拌均匀，得到分散剂；S2陶瓷浆料配置：将陶瓷粉体按化学计量比称取，加入陶瓷粉体0.2～1.0wt.％的分散剂，加入超纯水调节陶瓷浆料的体积固含量为14～18vol.％，然后进行球磨，即可得到乳化型陶瓷浆料；S3陶瓷浆料后处理：将乳化型陶瓷浆料加入陶瓷粉体1.0～1.5wt.％的聚丙二醇，然后进行水分脱除，搅拌后即可得到最终的陶瓷浆料。该制备方法能够直接实现长效稳定、多气泡的乳化陶瓷浆料制备，解决陶瓷浆料难存储、均匀性差、稳定差等制备难题，制备工艺简单，易于工业化生产。
