Description

一种防爆护眼保护膜
技术领域
本发明涉及电子应用胶带领域，具体为一种新型防爆护眼保护膜。
背景技术
随着电子产品的普及，各大LED显示电子产品，如手机、电脑、电视机、平板等深入千家万户，成为了日常生活不可或缺的一部分。但是电子产品显示领域，高能量的蓝光、及近紫外光的高能量光波，对人眼视网膜的伤害越来越大，而且在早教电子产品缺乏有效的护眼保护膜，导致近年儿童近视越来越多。市场上已有具有综合防蓝光和钢化膜功能的保护膜，但真正影响视力及眼睛健康的还有高能量的近紫外光，而且其防蓝光效果实测并不理想。
发明内容
本发明要解决的技术问题是克服现有技术的不足，提供一种集缓冲减震、柔性防爆、防蓝光、防UV、耐磨防刮等功能于一体，能同时实现防刮防爆和护眼的防爆护眼保护膜，以解决上述背景技术中的缺点。
为解决上述技术问题，本发明提出的技术方案为：
一种防爆护眼保护膜，包括基材，所述基材为光学级的缓冲材料TPU或EVA基材，所述TPU或EVA基材的一面涂覆亚克力胶水层并复合一层防蓝光PET，防蓝光PET外层涂覆硅胶层并复合一层离型膜，所述TPU或EVA基材的另一面涂覆一层防UV亚克力胶层，并于防UV亚克力胶层外复合一层高硬度防蓝光PET薄膜，所述高硬度防蓝光PET膜外复合一层离型膜；所述高硬度防蓝光PET薄膜是由防蓝光PET经过硬化处理得到，硬度≥3H。
作为上述技术方案的进一步改进：
优选的，所述的防UV亚克力胶层内添加有能吸收高能量UV的助剂（如CeO2、Er荧光粉）或能吸收蓝光的染料（如偶氮类有机物等）。
优选的，所述防爆护眼保护膜的厚度为0.08~0.4mm。
优选的，所述基材的透光率高于90%，所述助剂对高能UV光波的吸收率达90%。
与现有技术相比，本发明的优点在于：
本发明的防爆护眼保护膜，采用光学级的缓冲材料TPU作为基材，其透光率高于90%，缓冲性良好；防UV亚克力胶水，添加有能吸收高能量UV的助剂，对高能UV光波的吸收达到90%，能够有效减少高能紫外光对视网膜的伤害；防蓝光PET经过硬化处理得到高硬度防蓝光PET，其在保证高硬度的同时，具有防刮、耐磨、防指纹及防蓝光的功能。因此本发明集缓冲减震、柔性防爆、防蓝光、防UV、耐磨防刮等功能于一体，能同时实现防刮防爆和护眼等功能，可以取代传统护眼钢化膜以及单纯的防蓝光保护膜，可用于手机和笔记本等触摸显示保护，电子教育产品儿童视力保护等领域。
附图说明
图1为本发明较佳实施例的示意图。
图例说明：
1、离型膜；2、高硬度防蓝光PET；3、防UV亚克力胶层；4、基材；5、亚克力胶水层；6、防蓝光PET；7、硅胶层。
具体实施方式
为了便于理解本发明，下文将结合说明书附图和较佳的实施例对本发明作更全面、细致地描述，但本发明的保护范围并不限于以下具体的实施例。
参见图1所示，一种本发明的防爆护眼保护膜的较佳实施例，在本实施例中，防爆护眼保护膜的厚度为0.08~0.4mm，其基材4为光学级的缓冲材料TPU或EVA基材，在TPU或EVA基材的一面涂覆亚克力胶水层5并复合一层防蓝光PET6，防蓝光PET6外层涂覆硅胶层7并复合一层离型膜1；TPU或EVA基材的另一面涂覆防UV亚克力胶层3，并于防UV亚克力胶层3外复合一层高硬度防蓝光PET薄膜2，高硬度防蓝光PET薄膜2外也复合一层离型膜1，形成本发明的具有柔性防爆防蓝光抗UV功能的护眼保护膜。采用光学级的缓冲材料TPU作为基材，其透光率高于90%，缓冲性良好；防UV亚克力胶水，添加有能吸收高能量UV的助剂，对高能UV光波的吸收达到90%，能够有效减少高能紫外光对视网膜的伤害；防蓝光PET经过硬化处理得到高硬度防蓝光PET，硬度≥3H。其在保证高硬度的同时，具有防刮、耐磨、防指纹及防蓝光的功能。因此本发明集缓冲减震、柔性防爆、防蓝光、防UV、耐磨防刮等功能于一体，能同时实现防刮防爆和护眼等功能。
本实施例中，防UV亚克力胶层内添加有吸收高能量UV的助剂如CeO2、Er荧光粉或能吸收蓝光的染料如偶氮类有机物等。
本实施例中，采用的防蓝光PET6本身的性能方面就能有效提高护眼保护膜的护眼性能；而高硬度防蓝光PET薄膜2是防蓝光PFT6经过硬化处理得到，使其在保证高硬度的同时，还具有防刮、耐磨、防指纹及防蓝光的功能，更有效地提高了护眼保护膜的优良性能。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
