Description

一种手机贴膜
技术领域
本发明涉及一种手机贴膜。
背景技术
随着通信技术的发展，5G的时代即将来临，在原有电子产品中，金属手机后盖由于存在遮挡5G信号的问题，已满足不了现有的无线通讯技术，并且轻量化、薄片化、外观多样化的需求也越来越大。
目前越来越多手机等无线通讯设备，其外壳或后盖的生产倾向于采用塑料或者玻璃，并使用IMD注塑工艺来完成，具体地，需要把塑料制备成所需异形壳料或者对玻璃进行CNC加工，同时在表面进行丝印、电镀等处理，实现壳料的不同纹理、光栅效果，目前的工艺一般为GMF工艺，其步骤一般为：1.透明PC+PMMA复合板材，表面硬化，进行注塑或者热弯成型或者直接采用玻璃；2.内部贴合PET防爆膜，在PET防爆膜表面进行UV转印纹理或者拉丝，再在表面电镀颜色、然后进行表面丝印，最后与透明PC+PMMA复合板材复合热压成型或者直接与玻璃复合。采用上述工艺需要将防爆膜材料模切成片状，再进行UV转印、电镀以及印刷，整个工序的良品率和效率都极低。
发明内容
本发明所要解决的技术问题：针对现有技术的不足而提供一种手机贴膜，以解决上述问题。
本发明所解决的技术问题可以采用以下技术方案来实现：
一种手机贴膜，其特征在于，依次包括第一副膜、粘结层、基层、防爆层、第二副膜，所述第一副膜和第二副膜为离型层，所述粘结层为用于粘在表面的不干胶层，所述基层为光学级膜，所述防爆层包括以下重量份的各组分：丙烯酸树脂20-30份，聚氯乙烯40-50份，磷酸钙6-10份，二氧化硅2-12份，苯甲醇1-7份，硼化二钼5-10份，玻璃纤维素3-8份，2-羟基-4-甲氧基二苯甲酮2-6份，聚苯硫醚2-5份，钛白粉4-9份。
在本发明的一个优选实施例中，所述防爆层包括以下重量份的各组分：丙烯酸树脂25份，聚氯乙烯45份，磷酸钙8份，二氧化硅6份，苯甲醇8份，硼化二钼8份，玻璃纤维素5份，2-羟基-4-甲氧基二苯甲酮4份，聚苯硫醚4份，钛白粉6份。
在本发明的一个优选实施例中，所述防爆层与第二副膜之间还设置有抗蓝光膜层。
在本发明的一个优选实施例中，所述抗蓝光膜层与第二副膜之间还设置有防静电涂层。
在本发明的一个优选实施例中，所述基层为PET膜或PC膜或PMMA膜。
由于采用了如上的技术方案，本发明利用多层膜的复合结构，而且防爆层采用特殊的配方制成，大大增加了防爆性能。本发明还具有蓝光防护和静电防护功能。
