Description

耐腐蚀PET反光膜
技术领域
本实用新型涉及一种反光膜,尤其涉及一种耐腐蚀PET膜。
背景技术
现有的反光膜依次由设置的树脂层、聚酯树脂层、玻璃微珠层、聚焦层、金属反射层、压敏胶层和防粘纸组成,其表面虽然具有粘附力强、耐候性好的特点,但是聚酯树脂层与玻璃微珠层之间粘结牢度差,容易脱落、损坏,以及表面耐候性差而失去标识的反光效果,从而缩短了寿命。
实用新型内容
针对现有技术的不足,本实用新型提供一种耐腐蚀PET反光膜。
为了实现上述目的,本实用新型解决其技术问题所采取的技术方案是:
一种耐腐蚀PET反光膜,包括PET面层、PET中间层和PET底层,PET底层表面依次设置有反光层、压敏胶层和保护膜,压敏胶层中分布有玻璃微珠,PET中间层添加一PET回料。
所述的反光层为镀铝层。
所述的保护膜为缩丁醛保护膜。
本实用新型的有益效果:该实用新型采用PET三层共挤薄膜作为基材,耐腐蚀性能好;通过压敏胶层粘附玻璃珠,粘附性能好,不易剥离,缩丁醛保护膜耐候性强,各层材料共同作用,大大延长了使用寿命。
附图说明
图1为本实用新型的层状结构示意图。
具体实施方式
如图1所示,一种耐腐蚀PET反光膜,包括PET面层1、PET中间层2和PET底层3,PET底层3表面依次设置有反光层4、压敏胶层5和保护膜6,压敏胶层5中分布有玻璃微珠5.1,PET中间层2添加一PET回料,所述的反光层4为镀铝层,所述的保护膜6为缩丁醛保护膜。本实用新型的有益效果:该实用新型采用PET三层共挤薄膜作为基材,耐腐蚀性能好;通过压敏胶层粘附玻璃珠,粘附性能好,不易剥离,缩丁醛保护膜耐候性强,各层材料共同作用,大大延长了使用寿命。
