High solid content piezoelectric ceramic slurry for direct writing 3D printing and preparation method thereof
The invention relates to high solid content piezoelectric ceramic slurry for direct writing 3D printing and a preparation method thereof, the piezoelectric ceramic slurry comprises 85%-90% of a piezoelectric ceramic base material, 8.0%-12% of PVA, 1.0%-2.0% of glycerin and 1.0%-2.0% of a dispersant, and the piezoelectric ceramic base material is lead zirconate titanate or barium titanate piezoelectric ceramic powder with the particle size of about 500 nm. According to the direct-writing slurry, water serves as a solvent, the problem of solvent volatilization is effectively solved, polyvinyl alcohol and ammonium polyacrylate are both light toxic and harmless to the human body, the slurry preparation method is simple, and the defects that ceramic slurry materials prepared through similar technologies are high in toxicity, high in cost and complex in preparation process can be overcome. And in the subsequent sintering process, the problems of collapse, volume shrinkage and the like can be reduced due to the high solid phase content.
本发明涉及一种直写3D打印用高固相含量压电陶瓷浆料及其制备方法，其压电陶瓷浆料，包括85％～90％的压电陶瓷基料、8.0％～12％的PVA、1.0％～2.0％的甘油和1.0％～2.0％的分散剂，所述压电陶瓷基料为粒径约为500nm的锆钛酸铅或钛酸钡压电陶瓷粉体。本发明直写浆料以水为溶剂，有效解决溶剂挥发的问题，而且聚乙烯醇和聚丙烯酸铵均对人体轻毒无害，浆料配置方法简单，可以克服同类工艺制备陶瓷浆料材料毒性高，成本高，配制过程复杂的缺陷。并且在后续的烧结中，由于高固相含量可以减少塌陷和体积收缩等问题。
