Description

一种车窗节能反射膜
技术领域
本发明涉及汽车领域，尤其涉及一种车窗节能反射膜。
背景技术
目前普通汽车中车窗方面用的玻璃均为普通的光学玻璃，具有优秀的透光性，有利于驾驶员观察路面和交通情况。但是由于实际驾驶环境复杂，多有日光、来往车辆的远、近光灯产生的逆光或其他视线干扰；再加上日光长期直射车内会对车内部件产生老化或损坏。因此，需要在车窗上进行贴膜，汽车贴膜能够起到防紫外线、红外反射、防爆、防眩目、保护隐私以及美观等作用。然而，在目前的市场上有很多就采用普通染色的聚酯膜，无法实现全功能防护，不仅无法抗紫外、红外隔热，而且在强烈的太阳光下就分解、老化，有的还会产生有毒气体危害车主的身体健康，特别是对红外线的防护，尤其需要加强。
发明内容
发明目的：本发明为解决上述问题，提供了一种车窗节能反射膜。
技术方案：一种车窗节能反射膜，包括基膜、防雾抗刮层、防红外线层、防可见光层、防紫外线胶粘层、高硬度涂层；在所述基膜的上表面涂覆有防雾抗刮层；在所述基膜的下表面从内到外依次层叠防紫外线胶粘层、防可见光层、防红外线层、高硬度涂层；所述防红外线层包括外保护层、金属银层、金属钛层、ITO层、内保护层；所述防红外线层按远离基膜方向依次层叠外保护层、金属银层、金属钛层、ITO层、内保护层。
作为本发明的一种优选方案，所述基膜为PET薄膜。
作为本发明的一种优选方案，所述外保护层和外保护层为氧化硅膜层。
作为本发明的一种优选方案，所述金属银层厚度为20-40nm，所述金属钛层为10-30nm，所述ITO层厚度为20-40nm。
作为本发明的一种优选方案，所述内保护层和外保护层的厚度为20-60nm。
作为本发明的一种优选方案，所述防可见光层为染色聚酯膜层。
有益效果：本发明与现有技术相比，其优点在于，本发明提供的车窗节能反射膜能够有效降低可见光、红外线和紫外线，防爆、防眩目，耐候性好，并且不易变色和老化，使用寿命长。特别是防红外线层，传统车窗膜的防红外线层采用单一的金属膜层，一方面金属膜层容易被氧化变色，失去效果，另一方面金属膜层过薄的话防护效果不好，金属膜层过厚的话，影响车窗的可见度。本发明采用复合型的金属膜层，一方面提高了膜系的耐候性、耐腐蚀性，金属银膜层结合金属钛层，共同降低了热辐射；同时，通过综合调整2个金属膜层的厚度，可实现低辐射率、可见光高透过率、红外高反射率的调整，并且可以调整车窗节能反射膜的色度。另外ITO层和保护层可以防止有效防止金属膜层被氧化。
附图说明
图1是本发明的结构示意图。
其中，1为基膜；2为防雾抗刮层；3为防紫外线胶粘层；4为防可见光层；5为防红外线层；6为高硬度涂层。
具体实施方式
下面结合具体实施方式，进一步阐明本发明。
结合图1，本发明公开了一种车窗节能反射膜，包括基膜1、防雾抗刮层2、防红外线层5、防可见光层4、防紫外线胶粘层3、高硬度涂层6；在所述基膜1的上表面涂覆有防雾抗刮层2；在所述基膜1的下表面从内到外依次层叠防紫外线胶粘层3、防可见光层4、防红外线层5、高硬度涂层6；所述防红外线层5包括外保护层、金属银层、金属钛层、ITO层、内保护层；所述防红外线层5按远离基膜1方向依次层叠外保护层、金属银层、金属钛层、ITO层、内保护层。
具体的，所述基膜1可以选用PET薄膜。所述外保护层和外保护层为氧化硅膜层。所述金属银层厚度为20-40nm，优选为30nm；所述金属钛层为10-30nm，优选为25nm；所述ITO层厚度为20-40nm，优选为35nm。所述内保护层和外保护层的厚度为20-60nm。所述防可见光层4为染色聚酯膜层。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
