技术领域
本发明涉及太阳能组件领域,尤其涉及多层式太阳能背板的生产工艺。
背景技术
太阳能作为一种绿色环保、取之不尽的能源,无疑是取代传统火力发电的最佳选择,由于太阳能电池需要长期暴露在室外实用,所以光伏组件中的电池片需要加以保护,来防止大气中的水汽、氧气、紫外线等环境因素的影响和俯视。太阳能背板是整个太阳能电池的配件之一,主要起力学支撑和保护电池片免受环境因素渗透的作用,目前现有太阳能背板若反射性能较差易吸收太阳光,这就导致太阳能组件温度升高,大大降低了太阳能组件的光转化效率。
发明内容
本申请人针对上述现有问题,进行了研究改进,提供一种多层式太阳能背板的生产工艺,其具有良好的散热性和反射性,降低了光伏组件的老化速度,进一步提高了太阳能光伏组件的发电效率和寿命。
本发明所采用的技术方案如下:
一种多层式太阳能背板的生产工艺,包括以下步骤:
第一步:由放卷机进行PET基材供卷;
第二步:将配比好的粘合剂通过双辊滚涂机均匀的涂覆于PET基材的一侧表面;
第三步:将第二步中带涂覆粘合剂的PET基板输送至烘房中进行烘干固化,烘干温度为110~120℃,烘干时间为7~8分钟;
第四步:在带有粘合剂的PET基材料表面复合一层银色高反射层;所述银色高反射层包括含有高反射添加剂的聚乙烯、聚丙烯、聚烯烃或聚氨酯树脂中的一种,所述高反射添加剂包括氧化锌、氧化铝、氧化锆、钛白粉或荧光增白剂中的一种;
第五步:将第四步中复合银色高反射层的PET基材卷于纸芯上形成半成品进行晾置,晾置时间为1~5天;
第六步:利用配比好的粘合剂通过双辊滚涂机均匀的涂覆于第五步所得PET基材的另一侧表面;
第七步:将第六步中带涂覆粘合剂的PET基板输送至烘房中进行烘干固化,烘干温度为130~190℃,烘干时间为7~12分钟;
第八步:在带有粘合剂的PET基材料表面复合一层铝箔层;所述铝箔层为经过退火处理的软态高成型性铝箔;
第九步:将第八步所得PET基材卷于纸芯上形成成品背板进行晾置,晾置时间为1~5天;
第十步:将第九步所得背板根据客户需求进行切边、分卷;
第十一步:对第十步所得背板进行抽样检测,检测背板的性能及质量等级。
本发明的有益效果如下:
