1、摘要本文对反相微乳液法制备多组分陶瓷墨水及非水反相微乳液陶瓷墨水进行了研究。继续采用AE09,正丁醇/正辛烷/水反相微乳液体系作为配制陶瓷墨水的基本体系。在体系最佳组分配比和最佳温度为AE09:正丁醇:正辛烷=25.7wt%:16.8wt%:57.5wt%(25℃)时,采用直接合成法和间接合成法研究常规反相微乳液ZrO:-Ti02系和BaO.Zr02系多组分陶瓷墨水的工艺与参数。初步考察了MOA.5膊/正辛烷,水反相微乳液体系,绘制了不同组分配合后的体系拟三元相图。首次采用非水反相微乳液作为制备陶瓷墨水的反应介质,研究了AE09/正丁醇/『E辛烷/乙醇非水反相微乳液体
2、系。确定了反相微乳液区在体系拟三元相图中的位置,并分析了温度对相区的影响情况,得到最佳组分配比为AE09:正丁醇:正辛烷=29.1wt%:19.4wt%:51.5wt%。温度控制在30℃左右。在该体系中利用氧氯化锆乙醇溶液与氨水乙醇溶液反应,制备了Zr02非水反相微乳液陶瓷墨水。结果表明,墨水中Zr02陶瓷颗粒含量可达1.4wt%,平均粒径在50ran以内,均匀分散,能长时期稳定存在,墨水各项理化指标(除pH值偏低外)均满足间歇式喷墨打印机性能要求,电导率也接近连续式喷墨打印机的要求下限。由该体系所制备的Zr02陶瓷墨水的性能优于AE09系常规反相微乳液陶瓷墨水,说明
