技术领域
本发明涉及反光膜技术领域，具体是设计一种耐候性聚碳酸酯涂覆膜。
背景技术
反光膜是一种广泛应用于交通设施中的产品，当今的反光膜产品的基材主要使用PVC或亚克力材质，虽然聚碳酸酯基材具有更好的反光效率，但是受限于聚碳酸酯薄膜耐候性差的原因，现今市场上只有少量的聚碳酸酯反光膜产品，这些聚碳酸酯反光膜表面都需要覆盖一层亚克力进行保护（其耐候也不会超过5年）。因此为提高反光膜的耐候年限，急需一种高耐候性的聚碳酸酯薄膜，以满足反光膜领域应用的需求。
发明内容
针对上述存在的技术问题，本发明的目的是：提出了一种高耐候性聚碳酸酯涂覆膜，该涂覆膜具有超强的耐候性能，能够满足反光膜长达10年的耐候需求。
本发明的技术解决方案是这样实现的：一种耐候性聚碳酸酯涂覆膜，包括：
A层，为含氟树脂层或有机硅树脂层，所述A层的厚度为3-50um；
B层，为PC层，所述PC层包括PC和紫外吸收剂，所述PC质量份数98-100份，紫外吸收剂0.1~2份；
所述A层覆盖于所述B层至少一面，由此所述涂覆膜具有A-B两层结构或者A-B-A三层结构。
优选的：所述含氟树脂层是醚型FEVE共聚氟碳涂料、聚四氟乙烯树脂、聚三氟氯乙烯树脂中的一种。
优选的：所述有机硅树脂层是聚甲基硅树脂、聚乙基硅树脂、聚甲基苯基有机硅树脂、聚乙基苯基有机硅树脂中的一种或多种。
优选的：所述紫外吸收剂为二苯甲酮类或苯并三唑类。
优选的：所述A层和B层采用涂覆或者淋膜形式相结合。
优选的：所述PC层至少一面设有改性层；所述改性层由改性剂对PC层表面进行改性处理得到；所述改性剂为氨烃基硅烷偶联剂、含季氨烃基硅烷偶联剂、甲基丙烯酰氧烯烃硅烷偶联剂，烯烃基硅烷偶联剂、环氧烃基硅烷偶联剂中的一种；所述改性层厚度为0.01~5um。
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：本发明的一种耐候性聚碳酸酯涂覆膜，A层、B层和改性层通过涂覆或者淋膜技术实现结合。该涂覆膜具有超强的耐候性能，能够满足反光膜长达10年的耐候需求，可广泛应用于反光膜技术领域。
