Abstract
【解決手段】エチレン系共重合体および架橋剤からなるウェブとライナーとを積層し、該ウェブと該ライナーを共に搬送し、該ウェブを加熱溶融し、エンボス加工を施してなる太陽電池モジュール組立時の加熱架橋時にフィルムの縦方向(MD)及び横方向(TD)に共に実質的に寸法変化しないことを特徴とする太陽電池モジュール用封止フィルムによって解決する。

Description
エチレン−酢酸ビニル共重合体(酢酸ビニル含有量28%、MFR 20g/10分、融点 71℃)100質量部、t−ブチルパーオキシ2−エチルへキシルモノカーボネート1.0質量部、2−ヒドロキシ−4オクトオキシベンゾフェノン0.3質量部をリボンブレンダーでドライブレンドし、押出機(一軸、口径90mm)で溶融混練し、Tダイ1を用いてウェブ2を押し出した。Tダイ1の温度は90℃でスクリュー回転数は20rpmであった。押し出されたウェブ2をライナー巻き出しロール5からキャストロール3上に巻き出したライナー4(剥離紙、商品名:N−73GS、王子特殊紙製)と積層した後、搬送ローラー7によって搬送しながら、120℃のオーブン6によってウェブ2をライナー4と共に30秒間加熱した(ウェブ2の表面温度は90℃)。その後、エンボスロール9とゴムロール8間でエンボス加工を施し、冷却固化した後、剥離ロール10でライナー4と分離し、封止フィルム14を得た。
実施例1においてオーブン6における加熱処理時間を45秒とした(ウェブ2の表面温度は110℃)他は実施例1と同様にして封止フィルム14を得た。
実施例1においてオーブン6の温度を135℃、加熱処理時間を15秒とした(ウェブ2の表面温度は110℃)他は実施例1と同様にして封止フィルム14を得た。
実施例3においてオーブン6における加熱処理時間を30秒とした(ウェブ2の表面温度は120℃)他は実施例1と同様にして封止フィルム14を得た。
実施例1においてライナー4を用いないで製膜した。
実施例1においてライナー4を用いず、またオーブン6における加熱処理条件を100℃、15秒とした(ウェブ2の表面温度は75℃)他は実施例1と同様にして封止フィルム14を得た。
実施例1においてオーブン6における加熱処理条件を100℃、15秒とした(ウェブ2の表面温度は75℃)他は実施例1と同様にして封止フィルム14を得た。
実施例1においてライナー4を用いず、かつ、加熱処理をしないで製膜した他は実施例1と同様にして封止フィルム14を得た。
