Description
技术领域
本实用新型属于镀膜玻璃技术领域，具体的说是涉及一种三银LOW-E镀膜玻璃。
背景技术
三银LOW-E玻璃，即一种新型高端的低辐射玻璃，是在玻璃表面镀制包括三层银层在内的多层金属及其它化合物组成的膜系产品。由于银层具有低辐射的特性，从而使得该LOW-E玻璃对可见光有较高的透射率，对红外线有很高的反射率，具有优良的隔热和保温性能。目前，市场上的三银LOW-E玻璃一般都是低透型，市场可供选择的局限性比较大。
随着国家对低碳理念的推行，市场对LOW-E玻璃的节能环保性能要求越来越高，单一的遮阳型三银LOW-E产品已不能满足其需求，因此急需开发出一种透过率高，性能稳定，遮阳系数更低，光学性能和热工性能优良的高透型三银LOW-E玻璃，以满足市场对三银LOW-E高透市场的需求。
实用新型内容
本实用新型所要解决的技术问题在于克服现有技术之缺陷，提供一种透过率高，性能稳定，遮阳系数更低，光学性能和热学性能优良的三银LOW-E镀膜玻璃。

优选地，上述第一电介质层的厚度为20～60nm。
优选地，上述第一中间过渡电介质层的厚度为20～50nm，第二中间过渡电介质层的厚度为10～50nm。
优选地，上述第二电介质结合层厚度为5～25nm。
优选地，上述顶层电介质保护层的厚度为20～50nm。
优选地，上述金属氧化物保护层厚度为3～15nm。
优选地，上述第一阻挡层、第二阻挡层和第三阻挡层选自NiCr层、Nb层、Cr层、NiCrOx层、NbOx层、CrOx层、NiCrNx层、NbNx层、CrNx层中的一层或多层；所述第一阻挡层、第二阻挡层和第三阻挡层的厚度为0.5nm～8nm。
优选地，上述第一银层的厚度3～8nm，第二银层的厚度3～10nm，第三银层的厚度3～12nm。
上述三银LOW-E镀膜玻璃采用多层结构叠加设置而成，与传统的LOW-E玻璃相比，该三银LOW-E镀膜玻璃具有更加优良的光学与热学性能，更低的辐射率和遮阳系数以及优良稳定性能。优良的光学与热学性能使得该三银LOW-E镀膜玻璃对光的反射率更低，可使建筑物外视效果更加通透明亮，并有效减少眩光现象；更低的辐射率和更低的遮阳系数，使得该三银LOW-E镀膜玻璃具有更好的保温和隔热性能。

为了使本实用新型要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
本实用新型实施例提供一种透过率高，性能稳定，遮阳系数更低，光学性能和热学性能优良的三银LOW-E镀膜玻璃。如图1所示，该三银LOW-E镀膜玻璃包括玻璃基底层1，以及与该玻璃基底层1依次叠加设置的第一电介质层2、金属氧化物保护层3、第一银层4、第一阻挡层5、第一中间过渡电介质层6、第二银层7、第二阻挡层8、第二中间过渡电介质层9、第三银层10、第三阻挡层11、第二电介质层12、顶层电介质保护层13。
这样，上述三银LOW-E镀膜玻璃采用多层结构叠加设置而成，与传统的LOW-E玻璃相比，该三银LOW-E镀膜玻璃具有更加优良的光学与热学性能，更低的辐射率和遮阳系数以及优良稳定性能。优良的光学与热学性能使得该三银LOW-E镀膜玻璃对光的反射率更低，可使建筑物外视效果更加通透明亮，并有效减少眩光现象；更低的辐射率和遮阳系数，使得该三银LOW-E镀膜玻璃具有更好的保温和隔热性能。其中，三层银层具有低辐射的特性，赋予了该三银LOW-E镀膜玻璃优良的隔热和保温性能；三层阻挡层在有效的降低该三银LOW-E镀膜玻璃膜层厚度的同时，有效保护了三层银层不被氧化，提高了该三银LOW-E镀膜玻璃的稳定性能和增透性能；两层中间过渡电介质层具有良好的连接能力，使该三银LOW-E镀膜玻璃结构紧凑，牢固的同时，具有对光的高透过率；金属氧化物保护层3起到保护功能层的作用，保证该三银LOW-E镀膜玻璃的稳定性；第一电介质层2和第二电介质层12有效的增大了光的折射率，从而增强了该三银LOW-E镀膜玻璃增透性，同时又能很好的起到膜层连接作用和颜色的调控作用。

进一步优选地，如图1所示，第一电介质层2、第一中间过渡电介质层6、第二中间过渡电介质层9、第二电介质层12和顶层电介质保护层13选自TiO2层、ZnSnOx层、SnO2层、ZnO层、SiNxOy层、BiO2层、Al2O3层、Nb2O5层、SixNy层、Si3N4层中的至少一层，或者为TiO2、ZnSnOx、SnO2、ZnO、SiNxOy、BiO2、Al2O3、Nb2O5、SixNy、Si3N4中的至少两种混合的混合物层。

优选地，如图1所示，第一阻挡层5、第二阻挡层8和第三阻挡层11选自NiCr层、Nb层、Cr层、NiCrOx层、NbOx层、CrOx层、NiCrNx层、NbNx层、CrNx层中的一层或多层，该第一阻挡层5、第二阻挡层8和第三阻挡层10的厚度为0.5nm～8nm。该优选的三层阻挡层结构能进一步降低该三银LOW-E镀膜玻璃膜层厚度，进一步保护了三层银层不被氧化，提高了该三银LOW-E镀膜玻璃的稳定性能和增透性能。
优选地，如图1所示，上述第一银层4的厚度3～8nm，第二银层7的厚度3～10nm，第三银层10的厚度3～12nm。该优选的三层银层结构进一步提高该三银LOW-E镀膜玻璃隔热和保温性能，同提高了该三银LOW-E镀膜玻璃的光透过率。
