Description
ポリアクリル酸(日本触媒(株)製、分子量(Mw)10,000)1質量部を水87.77質量部に溶解した水溶液にオキサゾリン基含有ポリマー(日本触媒(株)製、エポクロス(登録商標)WS−700、分子量20,000)を1質量部加え、さらにpH調整剤として25%アンモニア水をpHが9になるように加えた混合液を厚さ0.2mm、幅35mm、長さ45mmの銅(リード導体)の表面に塗布した後120℃で5分間乾燥して複合皮膜層を形成した。
リード導体として厚さ0.2mm、幅35mm、長さ45mmのニッケルめっき銅を用い、実施例1〜3、比較例1と同様に複合皮膜層を形成し、表1に示す割合の熱融着層を用いてリード線を作製した。
作製したリード線を10mm幅に切断し、熱融着層とリード導体との接着力を180°剥離試験で測定した。なお引張速度は100mm/分とした。接着力が6N/cm以上のとき、良好と接着していると判断した。
エチレンカーボネート(EC)、ジエチルカーボネート(DEC)、炭酸ジメチル(DMC)を1:1:1の体積比率で混合し、電解質として六フッ化リン酸リチウム(LiPF6)を1.0mol/lとなるように溶解した電解液を準備した。この電解液にリード線を浸漬し、電解液の水分率が1000ppmになるように調整して60℃の恒温槽内に表1に示す期間放置した後、初期接着力の評価と同様に熱融着層とリード導体との接着力を測定した。
作製したリード線を136℃、130℃、125℃の恒温槽内に放置した後、180°に曲げた状態でクラックが発生するまでの日数を観察した。以上の結果を表1に示す。
