摘　　要：光伏背板在复合时易出现氟膜褶皱,通过实验室模拟,并测试基材收缩率、背板层间粘结力、剪切强度,对氟膜褶皱原因进行了分析。结果表明,氟膜和PET的剪切强度对背板表观影响较大,而当胶黏剂没有较明显固化时,胶黏剂的分子量对剪切强度影响较大。Fluorine film fold is easy to appear in the composite of photovoltaic backsheet,through laboratory simulation and test of substrate shrinkage,interlaminar bonding force and shear strength,the causes of fluorine film fold were analyzed.The results show that,the shear strength of fluorinated film and PET has great influence on the backsheet appearance,when the adhesive is not cured obviously,the molecular weight of the adhesive has a great influence on the shear strength.
