Description

一种抗紫外线的保护膜
技术领域
本发明属于保护膜技术领域，具体涉及一种抗紫外线的保护膜。
背景技术
玻璃、金属板材、塑料板材等材料在搬运和使用过程中，其表面容易受到接触性污染或磨痕划伤，所以通常采用保护膜覆盖在其表面使之免受损伤和污染。当待保护的材料为塑料等易受紫外线影响的高分子材料时，在日光和荧光下，因紫外线的作用，产生自动氧化反应，导致聚合物的降解而劣化，使外观及机械性能变坏。因此，有必要提供一种具有抗紫外线功能的保护膜。
发明内容
本发明是为了解决现有的抗紫外线功能的保护膜的抗紫外线效果不佳的技术问题，而提供一种抗紫外线的保护膜。
为了实现上述目的，本发明采用以下技术方案。
一种抗紫外线的保护膜，由紧贴于预保护基体一侧向外依次是基材层、电晕处理层、胶黏剂层、抗紫外线涂层和防刮耐磨层。
优选的，本发明制备的抗紫外线的保护膜厚度不超过0.2mm。
优选的，所述的基材层为聚对苯二甲酸乙二醇酯薄膜、双向拉伸聚丙烯薄膜、聚丙烯薄膜、聚乙烯薄膜或者聚酰亚胺薄膜。
优选的，所述的胶黏剂层为有机硅胶黏剂。
优选的，所述的电晕处理层的制备方法是，在所述的基材层上作电晕处理，形成覆盖有电晕处理层的基材层。
优选的，所述的抗紫外线涂层是由如下质量份的原料制备而成的：纳米二氧化硅3-7份、纳米二氧化锌5-7份、纳米二氧化钛3-5份、去离子水15-25份、异丙醇25-35份、KH570硅烷偶联剂8-12份、水性聚氨酯200-300份、有机硅树脂10-15份、氟硅树脂10-20份，其中，水性聚氨酯对紫外线短波有较强的吸收能力，纳米二氧化硅和纳米二氧化钛具有吸收紫外线的能力，纳米氧化锌禁带宽度大于4.5ev，吸收波长为280-320nm的紫外线，另外纳米氧化锌的颗粒尺寸远小于紫外线的波长，纳米粒子可将作用于其上的紫外线向各个方向散射，从而减少照射方向的紫外线强度。
优选的，所述的防刮耐磨层能够避免因意外对抗紫外线涂层的刮伤、撕裂，提高使用寿命。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
本发明与现有技术相比具有很好的隔热效果以及抗紫外线的能力，膜是多层结构，耐用性好等优点；经检测，该保护膜可阻挡波长为200~380nm的紫外光线，其阻挡率达到99%以上，可有效防止塑料和其他高分子材料在日光和荧光下，因紫外线的作用，产生自动氧化反应，导致聚合物的降解而劣化，使外观及机械性能变坏。
