Abstract

本发明公开了一种太阳能背板膜，包括以下重量百分比组分：聚偏二氟乙烯40%-45%，聚甲基丙烯酸甲酯10%-12%，黑色聚酯母料20%-27%，碳二亚胺化合物15%-20%，稀土1%-2%；本发明的背板膜内加入了稀土，增强了背板膜的耐腐蚀，也提高了背板膜的表面强度，从而提高了太阳能背板膜的使用寿命，使使用寿命达到26年以上，较一般的背板膜，使用寿命，提高了30%以上。

Description

一种太阳能背板膜
技术领域
本发明涉及一种太阳能背板膜。
背景技术
太阳能电池背板膜是用在太阳能铝框的一层薄膜，一般为白色20-25μm，分含氟和不含氟两种，主要起防水、隔离的作用。随着光伏产业的发展，太阳能背板膜需求大量增长，但是这类太阳能背板膜的耐腐蚀及强度均较低，不适合长时间的使用。
发明内容
本发明所要解决的技术问题是提供一种太阳能背板膜，该太阳能背板膜具有较长的使用寿命。
为了解决上述技术问题，本发明的技术方案是：
一种太阳能背板膜，其包括以下重量百分比组分：
优选的下重量百分比组分：
所述稀土的颗粒在2000目以上。所述碳二亚胺化合物是结构中含有碳二亚胺基团的化合物。
本发明的背板膜内加入了稀土，增强了背板膜的耐腐蚀，也提高了背板膜的表面强度，从而提高了太阳能背板膜的使用寿命，使使用寿命达到26年以上，较一般的背板膜，使用寿命，提高了30%以上。
具体实施方式
实施例1
选择下述原料：
将上述原料混合、结晶干燥经挤出机挤出，经纵向拉伸机、横向拉伸机拉伸，冷却后切边、收卷得到本发明薄膜。通过实验，较一般产品使用寿命提高至26年（实验数据换算获得）。
实施例2
选择下述原料：
将上述原料混合、结晶干燥经挤出机挤出，经纵向拉伸机、横向拉伸机拉伸，冷却后切边、收卷得到本发明薄膜。通过实验，较一般产品使用寿命提高至26年（实验数据换算获得）。
实施例3
选择下述原料：
将上述原料混合、结晶干燥经挤出机挤出，经纵向拉伸机、横向拉伸机拉伸，冷却后切边、收卷得到本发明薄膜。通过实验，较一般产品使用寿命提高至26年（实验数据换算获得）。
上述实施例不以任何方式限制本发明，凡是采用等同替换或等效变换的方式获得的技术方案均落在本发明的保护范围内。
