Description
技术领域
本发明涉及一种半反半透玻璃，属于节能技术领域。
背景技术
随着触摸屏显示行业的产品升级换代，其器件上的光学薄膜已不再是传统意义上简单的一层导电膜，而是需要兼具特殊的光学特性和功能性，对透过率、反射率、膜层颜色、膜层表面硬度、耐腐蚀性等都提出了严格的要求。然而，光学膜单层的厚度普遍在纳米量级，特别是多层光学膜叠加后，如何进行膜系设计，如何保证膜层量产的重复性，对于大多数企业而言绝非易事。
现有的平板电脑、触屏手机等智能触控电子产品，往往需要在表面贴半反半透光学膜，以实现半反半透的光学性能，在智能触控产品待机时可以起到镜面反射效果，可以作为镜子用于整理妆容、或梳理头发。也有在背盖玻璃上贴半反半透光学膜，从而前盖正常显示、触控，而后盖具备一定的镜面反射消影。
还有部分汽车，采用半反半透光学膜作为车载后视镜，从而即可以清楚观察到后面的交通情况，也可以避免后面车辆远视灯打开时，照射过来的光线经后视镜反射后并非全部强光反射，而是部分反射、部分透过，从而避免强光反射进入司机眼睛内而干扰司机的正常驾驶。
传统的半反半透光学膜是镀在PET柔性基材上再贴到手机、平板电脑的盖板玻璃上。一方面，贴膜时间长会气泡、剥离，影响半透半反的效果，另一方面，传统的半反半透膜的硬度不够高，在使用过程中容易划伤，从而影响产品的美观，而且耐酸碱性、耐溶剂型以及耐水性比较差。

优选地，所述第二功能膜层的厚度范围为60～80nm。
优选地，所述类金刚石膜层的厚度范围为1～5nm。
优选地，所述第一功能膜层和第二功能膜层通过真空磁控溅射镀膜工艺形成，所述真空磁控溅射工艺采用双交流旋转阴极、双交流平面阴极、双直流平面阴极、单直流平面阴极、单直流旋转阴极的至少其中之一在氩氧或氩氧氮氛围中沉积成膜。
