本申请要求于2022年2月15日提交中国专利局，申请号为202210138592.8，发明名称为“一种可阻断紫外线的EVA热熔胶膜及其制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及EVA热熔胶技术领域，尤其涉及一种可阻断紫外线的EVA热熔胶膜及其制备方法。
 背景技术
EVA热熔胶是以乙烯-醋酸乙烯热塑性聚合物为主体材料，与增粘剂、蜡类、增塑剂、抗氧剂、填料等其它高分子材料通过熔融共混合成的新型合成胶粘剂。它运输安全贮存便利，耗能较低，操作简易，利用加热的方法使胶粘剂软化熔融处于流态对粘接界面进行涂布，在脱离热源的很短时间内借冷却固化即实现粘接。
太阳光是一个巨大的能量体，因臭氧层被破坏导致强烈的紫外光直接照射地球，而紫外线因其具有较高的频率所以含有较大的能量，可以破坏一些有机聚合物的化学键使其老化。光伏组件是将太阳能转化成电能的设备，其包含有光电转换装置，即晶体硅电池片，若晶体硅电池片长期直接暴露在空气中，会降低其光电转换效率，失去实用价值，一般情况下，晶体硅电池片是借助两层高分子封装膜将其封装在其内，再通过EVA胶膜将其他材料封装在一起，使产品能够有效地防止外界的水、气、灰尘等等。
传统技术中EVA胶膜添加有紫外线吸收剂，对紫外线进行吸收，但仍然有少部分的紫外线能够穿过胶膜，使胶膜内产生由紫外线引发的自由基反应，使胶膜易于老化，进而进一步地影响晶体硅电池片的使用寿命。
