Description

一种改性锆钛酸铅粉体、其制备方法及压电陶瓷成型坯体
技术领域
本发明属于压电陶瓷技术领域,尤其涉及一种改性锆钛酸铅粉体、其制备方法及压电陶瓷成型坯体。
背景技术
压电陶瓷是一种能够将机械能和电能互相转换的信息功能陶瓷材料,是信息功能材料的重要组成部分。由于其具有较高的机电耦合系数、价格便宜、易于批量生产等优点,在通讯、声学、光学等各方面都获得了广泛的应用。如用于通讯设备中的陶瓷滤波器、陶瓷鉴频器以及陶瓷衰减器等;用于水下通讯和探测的水声换能器以及鱼群探测器等;用于电声器件中的扬声器、送话器等;此外在精密测量、导航、超声探伤、超声清洗、超声诊断等方面应用的器件也很多。而与其他压电材料相比,锆钛酸铅压电陶瓷具有较高的居里温度(380℃)和压电性能,并且易掺杂改性、稳定性好,是研究和使用最多的铁电材料。
传统的锆钛酸铅陶瓷成型技术,如干压、轧膜、流延等成型方法只能制备出几何形状简单的压电陶瓷器件,而注射成型法虽然能制备出几何形状相对复杂的陶瓷器件,但依然摆脱不了传统成型方法需要模具束缚。压电陶瓷器件具有体积小、精度高、几何形状复杂等特点,如何快速、方便的制备得到微小、精密、复杂的压电陶瓷器件成为本领域研究的热点。
3D打印是一种新兴的快速成型技术,与传统的成型技术相比,3D打印技术成型速度快,成型过程不需要模具和机械加工,且可以直接成型出几何形状复杂的器件,立体光固化成型技术(Sterolithography Apparatus,SLA)是目前世界上研究最为深入、技术最为成熟、应用最为广泛的一种3D打印技术。压电陶瓷器件具有体积小、精度高、几何形状复杂等特点,将3D打印技术应用于压电器件的制备中,不仅可以实现微小、精密、复杂形状的压电器件的快速制备,而且打印工艺简单、效率高、成本低,具有重大的科研和经济意义。而光固化成型技术对陶瓷粉体要求较高,使用现有的陶瓷粉体进行3D打印所制备的压电陶瓷很难成型、且致密度低、烧结样品存在变形、开裂和孔隙较多等缺陷,因此电学性能较差阻碍了实际应用。

实施例4打印制备压电陶瓷坯体
将30g的聚氨酯丙烯酸酯、70g的聚乙二醇(400)二丙烯酸酯、0.1g的α-羟基酮、0.1g的聚合物型分散剂取出经超声或磁力搅拌处理混合均匀,得光敏树脂。
将233g的实施例3所制得的Pb0.92Nb0.05Ni0.03(Zr0.55Ti0.45)O3粉体分10批(每批23.3g)加入到光敏树脂中,经超声处理混合均匀,再以300r/min的速率球磨60min,得到质量分数为70wt%的陶瓷浆料;陶瓷浆料如图3所示,所述球磨介质为500g直径为5mm的氧化锆陶瓷球。
将陶瓷浆料置于立体光刻机中的工作台内,设置设备参数:基层层数为10层,基层曝光时间为30s,单层打印时间为5s,单层打印厚度为20μm。按所设计陶瓷模型进行光固化成型,得成型后的陶瓷生坯,图4为成型的陶瓷坯体;所述立体光刻机的光源为紫外光,波长为405nm,曝光量为220mJ/cm2

Figure GDA0001569083930000091
而立体光固化机的分层层厚为20~100μm,激光功率为6~20mW/cm2,因此,采用本发明技术制备的锆钛酸铅粉体可用于立体光固化成型。
比较例
采用与实施例4相同的方法,将30g的聚氨酯丙烯酸酯、70g的聚乙二醇(400)二丙烯酸酯、0.1g的α-羟基酮、0.1g的聚合物型分散剂取出经超声或磁力搅拌处理混合均匀,得光敏树脂。
分别将233g的江西某公司生产的PZT粉、河北某公司生产的PZT5-1粉、山东某公司的PZT-5粉(分别称为:PZT-1#、PZT-2#、PZT-3#)分10批(每批23.3g)加入到光敏树脂中,经超声处理混合均匀,再以300r/min的速率球磨60min,配制成质量分数为70wt%的三种陶瓷浆料;陶瓷浆料如图5~7所示,所述球磨介质为500g直径为5mm的氧化锆陶瓷球。三种陶瓷浆料的特性如表2所示,不同激光功率下三种陶瓷浆料的固化深度如表3所示。
表2本发明比较例中陶瓷浆料的特性

表3本发明比较例中陶瓷浆料的固化性能(单位:μm)
Figure GDA0001569083930000093
Figure GDA0001569083930000101
从表2与表3可以看出,仅PZT-2#粉体的浆料特性较好,适用于立体光固化成型,但其固化效果差,不能应用于光固化成型,而PZT-1#、PZT-3#粉体的浆料特性及成型效果均差,难以光固化成型。因此,PZT-1#、PZT-2#、PZT-3#三种锆钛酸铅粉均不能应用于光固化成型。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
