具体的,所述单银低辐射玻璃100包括玻璃基底1和镀于玻璃基底1上的叠层结构的膜,所述玻璃基底1作为衬底,起到支撑的作用,所述膜起到阻挡红外辐射的作用。在本发明实施例中,叠层结构的膜通过溅射镀膜一层层形成于玻璃基底1上,溅射镀膜是一种新型的物理气相镀膜方式,就是用电子枪系统把电子发射并聚焦在被镀的材料上,使其被溅射出来的原子遵循动量转换原理以较高的动能脱离材料飞向基片淀积成膜。在其它实施例中,叠层结构的膜还可以通过蒸发镀膜、化学沉积等方法形成于所述玻璃基底1上,在此不做限定。本发明实施例的低辐射玻璃可以应用于建筑玻璃,车窗玻璃,以及其它需要低辐射能的场景。
具体的,玻璃基底1上的叠层结构的膜从下到上依次包括:底层电介质组合层10、第一电介质组合层20、第一阻挡层30、银层40、第二阻挡层50、第二电介质组合层60和顶层电介质组合层70。其中银层40作为功能层影响单银低辐射玻璃100的保温性能,其它电介质组合层和阻挡层调节玻璃的颜色。
具体的,底层电介质组合层10中包括金属层12和透明电介质材料层14,金属层12设置在透明电介质材料层14之间,起到外反射可以减反射的作用,减少可见光在透过玻璃时的反射率,增加可见光透过玻璃时的透过率,可以控制单银低辐射玻璃100的透过色,从而调节单银低辐射玻璃100的颜色,使得单银低辐射玻璃100在保证其颜色的情况下,银层40可以更厚。
具体的,底层电介质组合层10、第一电介质组合层20、第二电介质组合层60和顶层电介质组合层70分别设置为低折射率材料、高折射率材料、低折射率材料和更高折射率材料搭配,从而在玻璃基底1上形成高、低折射率材料搭配的减反射膜,减反射膜也可以减少可见光在透过玻璃时的反射率,增加可见光透过玻璃时的透过率,从而可以调节玻璃的颜色,提高银层40厚度,提升玻璃产品性能。
更具体的,第二电介质组合层60由高折射率透明电介质材料层和低折射率透明电介质材料层交替形成,从而在第二电介质组合层60也形成减反射膜,进一步提高单银低辐射玻璃100的膜层的减反射作用。
本发明技术方案通过在单银低辐射玻璃100的底层电介质组合层10的透明电介质材料层14之间设置金属层12,并且将各个膜层之间设置为高、低折射率材料搭配的结构,起到减反射膜的作用,使银层40厚度可以在传统厚度上大大增加,U值在原来基础上降低,使该低辐射玻璃对可见光有较高的透射率,对红外线有很高的屏蔽,具有良好的高保温性能。

性能测试
制备好上述实施例1至实施例6,以及对比例1至对比例3的单银低辐射玻璃,然后分别进行性能测试,性能测试包括决定单银低辐射玻璃的颜色的玻面反射颜色和透过色。另外将实施例1至实施例6,以及对比例1至对比例3的单银低辐射玻璃合成中空玻璃产品,测试不同实施例和对比例的单银低辐射玻璃制备的中空玻璃对应的透过率和U值,影响玻璃产品保温性能的指标。各实施例和对比例的性能检测结果如表2所示。
