针对上述存在的技术问题，本发明的目的是：提出了一种纤维增强型高性能复合薄膜。
本发明的技术解决方案是这样实现的：一种纤维增强型高性能复合薄膜，包含外保护层、基础层和增强层，外保护层为PVDF薄膜，基础层为铝箔，增强层为沿经向和纬向铺设的纤维丝束；所述外保护层通过粘结剂设置在基础层的一侧，增强层按经纬向呈网格状铺设于基体层的另一面，外保护层与基础层的层间剥离强度不低于3磅/英寸，外保护层、基础层和增强层的整体总厚度为35μm-100μm。
优选的，所述外保护层的厚度为18-25微米。
优选的，所述基础层的厚度为6.5-12μm。
优选的，所述纤维丝束为尼龙或芳纶纤维，纤维丝束之间平行且间隔距离为2.5mm-10mm，纤维丝束铺设前均经过粘结剂浸渍处理。
优选的，所述粘结剂由丙酮、VMA和聚氨酯组成，丙酮、VMA和聚氨酯的比例为1：3：0.4。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：
本发明的纤维增强型高性能复合薄膜，以PVDF为薄膜为外保护层，以铝箔为基础层，以纤维丝束为增强层，使整体具备良好的耐候性、耐久性等基础性能；外保护层与基础层通过特殊的粘结剂粘结，提高了剥离强度，并以纤维丝束为增强层，提高了整体强度。
附图说明
下面结合附图对本发明技术方案作进一步说明：
附图1为本发明的一种纤维增强型高性能复合薄膜的结构示意图。
具体实施方式
下面结合附图来说明本发明。
如附图1所示，本发明所述的一种纤维增强型高性能复合薄膜，包含外保护层1、基础层2和增强层3；所述外保护层1为PVDF薄膜，外保护层1的厚度为18-25微米；所述基础层2为铝箔，基础层2的厚度为6.5-12μm；所述增强层3为沿经向和纬向铺设的纤维丝束，纤维丝束为尼龙或芳纶纤维，纤维丝束之间平行且间隔距离为2.5mm-10mm，纤维丝束铺设前均经过粘结剂浸渍处理；所述外保护层1通过粘结剂设置在基础层2的一侧，增强层3按经纬向呈网格状铺设于基体层的另一面，外保护层1与基础层2的层间剥离强度不低于3磅/英寸，外保护层1、基础层2和增强层3的整体总厚度为35μm-100μm；所述粘结剂为由丙酮、VMA和聚氨酯组成的胶水，丙酮、VMA和聚氨酯的比例为1：3：0.4。
所述复合薄膜的制备方法如下：在铝箔上铺设胶水，将PVDF与铝箔用热熔复合机复合，温度为75-85℃，滚筒压力为4kg，然后放在熟化室内熟化2天，熟化温度为35-45℃；最后将复合品置于热压机上，将胶水铺设于铝箔上，将纤维丝束置于铝箔上，热压温度为90℃，时间为45s，间隔20min，重复热压3次。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
