Abstract
本发明提供了一种与电池片具有强粘结力的封装胶膜、形成其的组合物及应用。按重量份计，形成封装胶膜的组合物包括：100份聚合树脂，0.01～1份交联剂，0.01～1份助交联剂和0.01～1份助粘结剂，助粘结剂在封装温度下能够与电池片表面的二氧化硅发生化学反应。交联剂能够使聚合树脂之间发生交联，形成网状结构。在封装温度下，分布在聚合树脂中的助粘结剂能够与电池片上Si3N4表面的二氧化硅发生化学反应，这不仅有利于提高其形成封装胶膜与电池片之间的粘结强度，还有利于提高电池片中作为钝化层的氮化硅层的致密性，这有利于减少电池片的反射率，从而能够提高光伏组件的光电转换性能。
Description
技术领域
本发明涉及光伏领域，具体而言，涉及一种与电池片具有强粘结力的封装胶膜、形成其的组合物及应用。
背景技术
现有光伏领域，大尺寸光伏硅片研发成为本领域的研发热点。大尺寸光伏硅片对产业链成本的降低，不仅在于自身成本能低多少，更重要的在于大尺寸光伏硅片能够降低本领域中非硅部分的成本，使得产业链中各环节的相对竞争力增强，投资收益提升。但大尺寸光伏硅片的研发也给下游厂商带来了难题。比如在封装胶膜方面，原本依靠前后层封装胶膜粘接保护其中电池片，现在硅片尺寸变大会造成电池片的间隙变小，导致胶膜与胶膜粘接处变少，这使得本领域对封装胶膜与电池片之间的粘接力有了更高的要求。
现有文献提供了一种太阳能封装材料，采用三烯丙基异氰脲酸酯作为助交联剂，且三个烯丙基中一个或两个烯丙基被烷氧基甲硅烷基取代，从而提高了对透明基板如玻璃的粘和强度。
另一篇现有文献还提供了一种添加改性耦合剂的封装胶膜，通过在常用耦合剂570中添加0.1％～0.3％的2，6-二叔丁基对甲苯酚，增强偶联剂活性，利用甲基丙烯酰氧基基团与EVA中的碳碳双键相连，甲氧基基团与玻璃相连，从而使得玻璃与EVA薄膜粘黏起来，以增强EVA封装膜与玻璃之间的粘接力。
上述两种封装胶膜能够提高封装胶膜与基板或玻璃间的粘接强度，但是无法有效提高胶膜与电池片的粘接强度。鉴于上述问题的存在，有必要提供一种与电池片粘结力更加优异的封装胶膜。
发明内容
本发明的主要目的在于提供一种与电池片具有强粘结力的封装胶膜、形成其的组合物及应用，以解决现有的封装胶膜与电池片之间的粘接强度无法满足大尺寸光伏硅片对粘度方面的要求。
为了实现上述目的，本发明一方面提供了一种形成封装胶膜的组合物，按重量份计，形成封装胶膜的组合物包括：100份聚合树脂，0.01～1份交联剂，0.01～1份助交联剂和0.01～1份助粘结剂，其中，助粘结剂在封装温度下能够与电池片表面的二氧化硅发生化学反应。
进一步地，助粘结剂选自稀土氧化物、稀土氧化物与金属氧化物形成的二元或三元复合物、稀土氟化物与金属氧化物形成的二元或三元复合物组成的组中的一种或多种。
进一步地，助粘结剂选自Y2O3、镧系稀土氧化物、稀土氧化物与Al2O3形成的二元或三元复合物、稀土氧化物与MgO形成的二元或三元复合物和稀土氟化物与MgO形成的复合物组成的组中的一种或多种。
进一步地，助粘结剂选自Y2O3、Gd2O3、Eu2O3、Yb2O3、La2O3、Lu2O3、Y2O3-Al2O3复合物、Yb2O3-MgO2复合物、LaF3-MgO复合物、CeF3-MgO复合物和YF3-MgO复合物组成的组中的一种或多种。
进一步地，聚合树脂选自乙烯共聚物、聚丙烯、聚丁烯、聚氨酯弹性体、聚乙烯醇缩丁醛和有机硅橡胶组成的组中的一种或多种。
进一步地，按重量份计，形成封装胶膜的组合物还包括0～1份抗氧剂、0～1份光稳定剂、0～1份紫外光吸收剂、0～1份增粘剂和0～1份填料。
进一步地，按重量份计，形成封装胶膜的组合物包括100份聚合树脂，0.1～1份交联剂，0.1～1份助交联剂，0.1～0.3份助粘结剂，0～0.5份抗氧剂、0.02～0.3份光稳定剂、0～0.3份紫外光吸收剂、0.05～1份增粘剂和0～1份填料。
