Description

一种用于片式电容行业的透气ZrO2涂层的制备方法
技术领域
本发明属于耐火窑具制备技术领域，具体涉及一种用于片式电容行业的透气ZrO2涂层的制备方法。
背景技术
很多电容元件的化学性质都比较活泼，在窑具材料的选择上除了要考虑产品的耐火度、机械强度、热稳定性及使用成本之外，还要特别注意窑具材料的化学稳定性，避免与所接触的电容元件发生化学反应而影响产品的性能和窑具材料的使用寿命。对于片状式电容元件，在烧成过程中还要对窑具的表面透气性有极高的要求。当前，一种氧化锆涂层型窑具产品在片式电容行业得到广泛应用。在窑具材料表面喷涂一层氧化锆，使表面具有良好的特性，电容元件可以直接置于窑具材料上烧成。在窑具材料上使用涂层技术，实现了最佳窑具材料（耐火度高、 耐热冲击性好、 机械强度大）与最佳表面材料（化学惰性好、 平整光滑、 耐磨性高）的理想结合。
目前，市场上氧化锆涂层向着轻质化和表面喷涂的方向发展，大多是以等离子喷涂的方式实施的，虽然氧化锆涂层与刚玉氧化铝或刚玉-莫来石基材的结合强度高，但是其制作过程中因采用超高温等离子喷涂设备，水、电的消耗巨大，超高温下工作亦存在安全隐患等问题，并且等离子喷涂设备价格昂贵。而氧化锆粉体压制成型复合产品，由于氧化锆和氧化铝热膨胀系数的差异导致氧化锆层与刚玉或刚玉-莫来石基材的结合出现分层，均匀性不高等方面问题，而且使用效果不太理想，易出现粘连现象。
发明内容
本发明的目的在于针对背景技术中的不足，提供一种热震性能好，生产工艺简单，生产成本低的用于片式电容行业的透气ZrO2涂层的其制备方法。
为实现本发明的目的，所采用的技术方案如下：
一种用于片式电容行业的透气ZrO2涂层的制备方法，制备方法中ZrO2涂层的组分及各组分的质量百分比为：100～200目氧化锆颗粒30%～55%，氧化锆微粉25%～50%，粘结剂20%～30%；制备方法的具体步骤如下：
1）首先配置粘结剂：在粘结剂中加入分散剂与水混合均匀；
2）按质量百分比将氧化锆原料和粘结剂混合均匀，制备出不易沉降的氧化锆涂料；
3）将窑具材料表面做润湿预处理后，选用普通喷枪采用常温压力雾化喷涂工艺在窑具材料表面形成氧化锆涂层；
4）将喷涂好的窑具材料自然干燥8～12小时，然后入电加热干燥器在120℃下进行8～12小时烘干；
5）烘干后，在1400～1600℃温度下烧制3～4小时。
所述的氧化锆颗粒、氧化锆微粉为氧化钇稳定氧化锆，氧化镁稳定氧化锆，或者氧化钙稳定氧化锆。
