Description
技术领域
本发明涉及焊带技术领域，特别涉及一种提样能电池片黑色焊带的制 作方法。
背景技术
太阳能电池是通过光电效应或者光化学效应直接把光能转化成电能 的装置。太阳能电池在使用前，需要首先通过焊带将太阳能电池片连接起 来，从而汇集并输出太阳能电池片在阳光照射下产生的电流。焊带是电流 收集的关键，对光伏组件的功率影响很大。目前所采用的用于连接太阳能 电池片的焊带为锡的本色(银白色)，无法满足客户的审美要求。
发明内容
针对以上现有技术存在的缺陷，本发明的主要目的在于克服现有技术 的不足之处，公开了一种太阳能电池片黑色焊带，包括焊带和涂覆在焊带 表面的黑色涂料，所述黑色涂料原料是由如下重量份数的各组分组成：
进一步地，有机树脂为丙烯酸树脂。
进一步地，所述发泡剂为碳酸盐。
进一步地，所述散热粉为氮化硼碳、纳米管、石墨烯、氧化铝、氧化 锌、氧化镁及碳化硅中的一种或多种。
进一步地，所述黑色颜料为碳黑。
一种太阳能电池片黑色焊带的制作方法，包括以下步骤：
将偶联剂和黑色颜料、导电粉、散热粉混合分散，使其分散均匀；
加入分散剂、发泡剂、氯化聚烯烃、杜邦DBE和有机树脂混合分散， 分散时间为5分钟，分散转速1000转/分钟，将分散后的混合物放置在 120℃的环境中，放置时间为10分钟，而后升温至270℃，静置1分钟， 取出后加入消泡剂混合分散，分散时间为5分钟，分散转速1000转/分钟； 分散完毕后真空除气，得到黑色胶液；
将所述黑色胶液涂布于焊带表面，并在120-160℃的温度下烘烤固化 至少30分钟，制得黑色焊带。
进一步地，所述黑色颜料为碳黑。
本发明取得的有益效果：
本发明的黑色焊带，通过对黑色涂料工艺和配方的改进，提高颜料的 附着力。黑色颜料选用碳黑，并且配合氯化聚烯烃，有效提高颜色的附着 力。混合分散通过散步实现，首先混合发泡剂，而后在高温中静置，使已 经混入其中的发泡剂产生气泡，进行再次混合，并且在高温下将发泡剂的 气体除尽，降低发泡剂残留对涂料的影响，最后加入消泡剂再次进行混合 分散，进而消除和抑制气泡产生，提高了物料混合分散的均匀程度；另外， 增加导电粉和散热粉提高表面导电能力。
