Description
1. 第1の接着剤層溶液の製造
水分吸着剤としてCaO(平均粒径5μm未満)溶液(固形分20%)を製造し、前記溶液を分散させてCaOが均一に分布されるようにした。また、これとは別に、エポキシ樹脂(YD−128、KUKDO化学)100g及びフェノキシ樹脂(YP−70、東都化成)70gをメチルエチルケトンで希釈した溶液(固形分70%)を製造した後、溶液を均質化した。前記均質化された溶液にあらかじめ準備したCaO溶液250gを投入し、硬化剤であるイミダゾール(四国化成)5gを投入した後、1時間の間高速撹拌して第1の接着剤層の溶液を製造した。
エポキシ樹脂(YD−128、KUKDO化学)100g及びフェノキシ樹脂(YP−70、東都化成)90gをメチルエチルケトンで希釈した溶液(固形分70%)を製造した後、溶液を均質化した。硬化剤であるイミダゾール(四国化成)5gを投入した後、1時間の間高速撹拌して第2の接着剤層の溶液を製造した。
前記準備した第1の接着剤層の溶液を離型PETの離型面にコンマコートを使用して塗布し、乾燥器で130℃に3分間乾燥し、厚さが50μmの第1の接着剤層を形成した。
実施例1の製造過程で、第1の接着剤層の厚さを40μmに変更し、第2の接着剤層の厚さを10μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=4)。
実施例1の製造過程で、第1の接着剤層の厚さを30μmに変更し、第2の接着剤層の厚さを15μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=2)。
実施例1の製造過程で、第1の接着剤層の厚さを15μmに変更し、第2の接着剤層の厚さを15μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=1)。
実施例1の製造過程で、第1の接着剤層の厚さを5μmに変更し、第2の接着剤層の厚さを50μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=0.1)。
実施例1の製造過程で、第1の接着剤層の厚さを60μmに変更し、第2の接着剤層の厚さを3μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=20)。
実施例1の製造過程で、第1の接着剤層の厚さを20μmに変更し、第2の接着剤層の厚さを2μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=10)。
実施例1の製造過程で、第1の接着剤層の厚さを100μmに変更し、第2の接着剤層の厚さを20μmに変更したこと以外は、実施例1と同一に実施して接着フィルムを製造した(厚さの割合T1/T2=5)。
実施例1と同一の接着フィルムの製造過程を実行するが、実施例1の第1の接着剤層のみからなる厚さが45μmの接着フィルムを製造した。
実施例1と同一の接着フィルムの製造過程を実行するが、実施例1の第2の接着剤層のみからなる厚さが45μmの接着フィルムを製造した。
実施例1と同一の接着フィルムの製造過程で実施するが、実施例1の第2の接着剤層溶液のフェノキシ樹脂を20gに変更したことの以外は、実施例1と同一に実施して接着フィルムを製造した。
実施例1〜実施例4及び比較例1〜比較例7の接着フィルムの水分遮断特性を調査するために、カルシウムテストを進行した。具体的には、100mm×100mmサイズのガラス基板上にカルシウム(Ca)を5mm×5mmのサイズ及び100nmの厚さで9個(9 spot)蒸着し、これとは別に、実施例1〜実施例4及び比較例1〜比較例7の接着フィルムを、図4に示したように、17mm×17mmサイズの上板ガラスに80℃で1分間加熱圧着した。その後、上板ガラスに合着された接着フィルムを下板ガラスに同一に真空(100mTorr未満)で加熱圧着した。その後、圧着された上下板ガラスを高温乾燥器内で100℃に3時間硬化させた後、得られた試片を恒温恒湿チャンバで85℃の温度及び85%R.H.の環境で1000時間の間放置した後、6mmべゼルを耐える時間を水分浸透による酸化反応によってカルシウムが透明になり始めた時点を評価し、下記表1に示した。
実施例1〜実施例4及び比較例1〜比較例7の接着フィルムを利用して3インチの有機発光パネルを製造し、恒温恒湿チャンバで85℃の温度及び85%R.H.の環境に1000時間の間放置した後、光学顕微鏡で有機素子の損傷を観察し、下記表2に示した(但し、水分浸透による損傷は無視した状態の結果である。)
ARESを利用して実施例1と比較例7の接着フィルムの第1の接着剤層及び第2の接着剤層の粘度を各々測定し、80℃での粘度及びその差を下記表3に示した。
