| 研究了硅烷偶联剂类型以及层压温度对 EVA 太阳能电池封装膜 / 玻璃剥离强度的影响。 发现含双键的硅烷偶联剂直接加入 EVA 胶膜可以有效提高剥离强度,但是剥离强度较低,对层压温度比较敏感,随着层压温度的提高而降低。 然后采用底涂方法,即预先将玻璃表面用不同类型的偶联剂处理,再与不含硅烷偶联剂的EVA 太阳能电池胶膜进行热压复合的方法,研究了硅烷偶联剂类型对剥离强度的影响。 实验结果表明,含双键的硅烷偶联剂 KH-570 和 Z-6032 能非常有效地提高 EVA 胶膜与玻璃之间的剥离强度,而且其效果要明显好于未经硅烷偶联剂处理的玻璃与含硅烷偶联剂的 EVA 胶膜之间的剥离强度。 同时发现,KH570 等疏水性较好的硅烷偶联剂,能够有效地提高湿热老化(双 85 实验)条件下,EVA 胶膜与玻璃之间的剥离强度。 |

| Abstract: |
| The influence of the type of silane coupling agent and lamination temperature on the peeling strength between EVA encapsulation film and glass was investigated. It was found that double bond containing silane coupling agent can effectively improve the peeling strength. However, the peeling strength is still not satisfactory at relatively high curing temperature. Glasses treated with different type of silane coupling agents were adhered with EVA encapsulation films that do not contain silane coupling agents for photovoltaic modules. The peeling strength was found to be determined by the type of silane coupling agent used as the primer of glass. KH570 and Z-6032, which contains methacrylate and vinyl groups, respectively, are the most effective silane coupling agents for the improvement of peeling strength. It was found that the peeling strength between the non-primed glasses and silane coupling agent containing EVA encapsulation films is relatively lower than primed glass and EVA films without silane coupling agent. Several primer formulations, especially hydrophobic silane KH570, were found in damp-heat test to be able to remarkably improve the EVA peeling strength in damp-heat conditions. |
