红外截止膜以及镀有红外截止膜的产品
技术领域
本发明涉及光学技术领域，具体涉及一种红外截止膜以及镀有红外截止膜的产品。
背景技术
近年来，随着科学技术的飞速发展，红外截止膜产品的应用领域也日渐广泛，如建筑的外幕墙或门窗，微波炉或冰箱上的玻璃门，汽车、高铁或飞机上的玻璃窗户等等。传统该类产品主要采用金属材料作为整个产品的功能层，尤以银材料最为常见。
然而，上述该类产品也有局限性，如金属材料性能不稳定，该类产品如果单片裸露在应用场所，外界干扰物(例如水汽、汗液、唾液、其他的化学试剂等)可穿透膜层中的介质层和保护层使金属功能层受到破坏，从而造成其截止红外线的功能将减弱或消失。为了使产品能正常使用，目前的解决措施主要是将产品以中空结构在各种应用场合使用；即一般情况下需要将镀膜产品通过间隔条与另一片玻璃做成中空结构(见图1)，并辅以干燥剂及多层密封胶对膜层进行保护，使其使用寿命得到增加。但是，此种膜层结构生产的产品，制作工艺复杂，在实际加工制作过程中不良率偏高，生产效率低下，成本费用高，且终端产品在使用一定年限后具有失效风险。基于此，为了解决上述缺陷，提供一种新型的红外截止膜具有重要意义。

优选地，采用磁控溅射法在基材上镀红外截止膜，控制磁控溅射的本体真空度<8×10-6mbar；且镀膜材料的种类大于或等于两种时，相邻两个不同工艺气氛的隔离系数>20；之后将镀膜后的基材进行钢化处理，最终得到红外截止膜。当然，本领域技术人员可以选用其他方法制备具有上述组成和结构的红外截止膜。
第二方面，本发明提供一种镀有红外截止膜的产品，镀有红外截止膜的产品结构采用单片式结构、夹胶式结构和中空式结构中的一种或多种。
