Description

一种太阳能膜片
技术领域
本发明涉及一种用于太阳能膜片。
背景技术
目前聚乙烯醇缩丁醛(PVB)膜片是用于制造安全玻璃、防弹玻璃的特殊产品。安全玻璃是在两层普通玻璃之间夹入一层具有独特粘接性能，良好的低温抗冲击性能、良好的曲挠性、良好的透光性能以及耐光、耐候、隔音、隔紫外线等性能均佳的聚乙烯醇缩丁醛(PVB)膜片而制成的特种玻璃，在受到外界强烈冲击时，PVB膜片能够吸收冲击能量，使这种玻璃不发生破碎及产生碎片而伤人，而且加入聚乙烯醇缩丁醛膜片的安全玻璃具有透明度高、耐水、耐老化的特性，并且能在-60℃的环境里使用，此外还可以代替有机玻璃作透明材料等产品，多层复合即可制成军用防弹玻璃。
近年来，随着国民经济的发展，光伏产业在国家大型工程项目、推广计划和国际合作项目的推动下，以前所未有的速度迅速发展。目前，中国已经成为世界上产量最大的太阳能消费品生产国。由于PVB独特的物理化学性能，PVB成为制造夹层玻璃的最佳选择，并作为封装材料开始应用在光伏组件上。与传统光伏组件封装材料EVA相比，PVB膜片拥有库存时间更长，重复层压无交联发生，耐候性更好等性能。而与普通PVB膜片相比，应用于太阳能光伏组件上的PVB膜片，需要有更好的透光率、更好的耐候性、以及绝佳的绝缘性。
