摘要
粘接强度是影响EVA太阳能电池封装胶膜使用性能的一个重要因素,通过添加偶联剂和增粘树脂可明显提高其粘接性能。研究探索了硅烷偶联剂类型和增粘树脂种类、含量对老化前后粘接性能的影响。实验结果表明,硅烷偶联剂KH550和KH570复配,然后加入0.2%(质量分数)的增粘树脂改性松香,可以得到初粘力在85 N/cm的封装胶膜,并且具有良好的湿热稳定性。
The adhesion strength of EVA encapsulation films to glass substrates is an important factor influencing the performance, reliability and durability of photovoltaie modules. Coupling agent and tackifying resins were applied to improve the adhesion strength. The effect of the type of silane coupling agents, the content and type of tackifying resins on the peeling strength between EVA and glass substrates were discussed. The experimental results showed that the initial adhesion strength of EVA encapsulation film reached 85N/cm when the mixtures of KH570, KH550 silane coupling agents and 0.2% modified rosin resin was added.
