Description

一种低表面光泽度聚偏氟乙烯薄膜及其制备方法
技术领域
本发明涉及一种低表面光泽度聚偏氟乙烯薄膜及其制备方法,属于太阳能光伏电池应用领域。
背景技术
太阳能是取之不尽、用之不竭的清洁能源。太阳能电池是通过光电效应直接把光能转化为电能的装置。太阳能电池组件一般包括前板钢化玻璃、EVA胶膜、电池片、背板、边框及接线盒等。电池片不耐候,尤其在潮湿的环境中电转换效率急剧下降,甚至损坏。背板处于太阳能组件的北面,其作用是保护电池片,起封装、绝缘与阻水隔气的作用。常见的背板一般具有三层结构:内层为聚乙烯(PE)薄膜或含氟涂层;中间层为双向拉伸的聚对苯二甲酸乙二醇酯(PET)薄膜;外层是氟膜,包括聚氟乙烯(PVF),聚偏氟乙烯(PVDF)或其他含氟材料。
聚偏氟乙烯是一种性能优异的含氟材料,具有突出的耐高低温、耐化学腐蚀、耐候性以及优异的电绝缘性,这些优良性能使PVDF能够满足太阳能电池封装背板外层保护膜的要求。美国的Akema公司制备了PVDF薄膜,商品名为Kynar,但存在以下缺点,即薄膜表面光泽度高,超过了50度,由于剧烈反光而影响了背板的自动层压工艺,逐渐被市场淘汰。CN102010554A公开了一种PVDF薄膜专用料,其优点在于流动性好,易成型;专用料制备的聚偏氟乙烯薄膜具高机械强度、高耐候性、低热收缩率及高水、汽阻隔性等优点。此专利中制备的也是表面光泽度高的PVDF薄膜。塑料薄膜表面光泽度的测量参照国家标准GB8807-88“塑料镜面光泽实验方法”进行,对样品均采用45°角测量。本发明要解决的技术问题之一是:研制具有低薄膜表面光泽度,即表面光泽度低于30,且性能满足要求的PVDF薄膜,用于太阳能电池背板上对太阳能电池组件进行封装。
