Description

复合靶材及其制备方法
技术领域
本发明涉及一种复合靶材及其制备方法，尤其涉及一种可制取具有疏水、防紫外线及自清洁功能透明薄膜的复合靶材及该复合靶材的制备方法。
背景技术
在玻璃表面镀膜的方法较多，主要有物理气相沉积、化学气相沉积及溶胶-凝胶等。物理气相沉积中常用的真空磁控溅射技术可设计多层复杂膜系，在玻璃基体上镀覆出性能较佳的膜层，是目前使用最广泛的玻璃镀膜技术之一。
基于玻璃基材的特殊性能，对玻璃镀膜的膜层有较高的要求，通常要求膜层具有较高的透光率，选择性透光，高阻隔比，如高的红外线、紫外线阻隔效果等，因此膜层的选择设计十分重要。目前要实现在玻璃上制备具有疏水、防紫外线、自清洁效果的透明功能薄膜，通常需要设计相应的多层复合膜系结构，如此一来导致制备薄膜的工艺时间长，产品的成本增加。
发明内容
有鉴于此，有必要提供一种可制取具有疏水、防紫外线及自清洁功能透明薄膜的复合靶材。
另外，还有必要提供一种上述复合靶材的制备方法。
一种复合靶材，其含有质量百分比为50％-85％的氧化钛以及余量的氧化锡或氧化铝。
一种复合靶材的制备方法，其包括以下步骤：
将质量百分比为50％-80％的氧化钛粉体，质量百分比为15％-50％的氧化锡粉体或氧化铝粉体及质量百分比为5％-10％的粘结剂混合均匀，制得一混合物；
将所述混合物放入模具中热压制成一坯体；
对所述坯体进行高温烧结；
烧结后自然冷却。
本发明复合靶材可用于真空磁控溅射制备具有疏水、防紫外线及自清洁功能的透明薄膜；本发明复合靶材的制备方法工艺简单、制程周期短，易于设计及控制、应用范围广泛。
具体实施方式
本发明一较佳实施方式的复合靶材，其含有质量百分比为50％-85％的氧化钛以及余量的氧化锡或氧化铝。
上述复合靶材的制备方法包括如下步骤：
将质量百分比为50％-80％的氧化钛粉体，质量百分比为15％-50％的氧化锡或氧化铝粉体，质量百分比为5％-10％的粘结剂混合搅拌均匀，制得一混合物。该氧化钛粉体的纯度可为97-99％，粒度可为70-90μm。该氧化锡粉体的纯度可为97-99％，粒度可为70-90μm。该氧化铝粉体的纯度可为97-99％，粒度可为70-90μm。该粘结剂中含有正硅酸乙脂及有机溶剂，其中正硅酸乙脂及有机溶剂的质量比可为1∶10。该有机溶剂可为乙醇或丙酮。
取适量上述混合物放入模具中，将该混合物压制成一坯体。压制的温度范围可为100-300℃，压力可为100-200吨。
对压制成型的坯体进行高温烧结，烧结温度为900-1800℃，烧结时间为3-4h。烧结过程中所述粘结剂中的有机溶剂及有机物被燃烧去除，而该粘结剂中的硅在烧结后以二氧化硅的形式存在于所述复合靶材中。
烧结完成后自然冷却，制得所述的复合靶材。
