摘要
分别采用聚丙烯酸铵和海因环氧树脂为分散剂和凝胶剂,制备锆钛酸铅(PZT)压电陶瓷浆料,研究了分散剂含量、球磨时间、固相含量以及树脂含量等因素对浆料流变性能的影响,结果表明,当分散剂加入量为0.6%、球磨时间为24 h及固相体积含量为55.0%时,浆料流变特性最佳.浆料粘度随着树脂含量增加而增大,但即使树脂含量高达25.0%,浆料流动性依然能较好满足浇注成型的需求.
The lead zirconate titanate（ PZT） suspensions were prepared using the ammonium polyacrylate and Hydantion epoxy resin as the dispersant and the gelling agent,respectively.The effects of the dispersant concentrations,the milling time,the solid loading and the epoxy resin content on the rheological properties of the PZT suspensions were systematically investigated.The results show that the rheological property of the PZT suspesion was the best when the dispersant concentration,the milling time and the solid loading were0. 6%,24 h and 55.0%,respectively. Although the viscosities of the suspensions increasedwith the increase of the epoxy resin content,the fluidity of the suspension even with 25.0%resin was still good for the requirement of the gelcasting process.
