Abstract
Description
本発明の主要な目的は、他の熱可塑性樹脂層との接着性に優れたフッ化ビニリデン系樹脂シート、特にその良好な接着性を生かして、他の熱可塑性樹脂層との積層状態におかれるフッ化ビニリデン系樹脂の押出シートを提供することにある。
得られた重合体のカルボニル基の定量は、以下の方法によって行った。
(合成例1)(フッ化ビニリデン共重合体1の調製)
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.6g、酢酸エチル3g、ジイソプロピルパーオキシジカーボネート4g、フッ化ビニリデン398g、マレイン酸モノエチルエステル2gを仕込み(フッ化ビニリデン:マレイン酸モノメチルエステル=100:0.50)、25℃で42時間懸濁重合を行った。重合完了後、重合体スラリーを脱水、水洗後、80℃で乾燥して粉体状の共重合体1を得た。
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.8g、酢酸エチル2.5g、ジイソプロピルパーオキシジカーボネート4g、フッ化ビニリデン396g、マレイン酸モノエチルエステル4gを仕込み(フッ化ビニリデン:マレイン酸モノメチルエステル=100:1.01)、28℃で47時間懸濁重合を行った。重合完了後、合成例1と同様に処理して粉体状の共重合体2を得た。
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.4g、酢酸エチル8g、n−プロピルパーオキシジカーボネート2g、フッ化ビニリデン400gを仕込み、25℃で22時間懸濁重合を行った。重合完了後、合成例1と同様に処理して粉体状の重合体3を得た。
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.4g、酢酸エチル8g、n−プロピルパーオキシジカーボネート2g、フッ化ビニリデン399.8g、マレイン酸モノエチルエステル0.2gを仕込み(フッ化ビニリデン:マレイン酸モノメチルエステル=100:0.05)、を仕込み、25℃で24時間懸濁重合を行った。重合完了後、重合体スラリーを合成例1と同様に処理して粉体状の共重合体4を得た。
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.6g、酢酸エチル6g、イソプロピルパーオキシジカーボネート4g、フッ化ビニリデン375.2g、クロロトリフルオロエチレン24g、マレイン酸モノエチルエステル0.8gを仕込み(フッ化ビニリデン+クロロトリフルオロエチレン:マレイン酸モノメチルエステル=100:0.20)、を仕込み、25℃で25時間懸濁重合を行った。重合完了後、重合体スラリーを合成例1と同様に処理して粉体状の重合体5を得た。
内容量2リットルのオートクレーブに、イオン交換水1040g、メチルセルロース0.4g、酢酸エチル8g、n−プロピルパーオキシジカーボネート2g、フッ化ビニリデン352g、ヘキサフルオロプロピレン48gを仕込み、25℃で20時間懸濁重合を行った。重合完了後、重合体スラリーを合成例1と同様に処理して粉体状の重合体6を得た。
得られたフッ化ビニリデン(共)重合体を下表1に示すとおり、単独であるいはブレンドして、同方向回転二軸押出機を用いてペレット化することにより、実施例1〜6および比較例1〜2のフッ化ビニリデン(共)重合体組成物を得た。押出に際しては、ダイス出口での樹脂温度が、220〜250℃の範囲内になるようにシリンダー温度条件を調整した。
比較のため市販の接着性改良共重合体フッ化ビニリデン系樹脂(無水マレイン酸グラフトポリフッ化ビニリデン;アルケマ社製「Kynar ADX20」;特許文献3実施例で使用)を用いた。
他の熱可塑性樹脂として、以下の二種のポリアミド樹脂を用いた:
・市販ポリアミド12(ダイセルデクサ社製「ダイアミドX7293」)
・市販接着性改良ポリアミド12(ダイセルデグサ社製「ダイアミドX7297」)。
上記実施例1〜6あるいは比較例1〜3のフッ化ビニリデン系樹脂(組成物)の一種と、上記他の熱可塑性樹脂(ポリアミド)一種とを、単軸スクリュー押出機2台(フッ化ビニリデン系樹脂用とポリアミド用)と、マルチマニホールド多層Tダイとを用いて共押出しして、厚み540μm(フッ化ビニリデン系樹脂層180μm、ポリアミド層360μm)の二層シート18種を得た。
得られた二層シートの外観を目視で観察して、以下の基準で評価した:
A:押出性良好であり、二層シートのいずれの層の外観も良好、
B:押出性良好であるが、二層シートのフッ化ビニリデン系樹脂層の表面にわずかに縦筋が発生した、
C:フッ化ビニリデン系樹脂層の発泡が起こり、表面荒れおよび顕著な縦筋が発生して、連続的な運転が不可能であった。
JIS K6854−3に規定される接着剤のT剥離強度の測定法に準拠し、多層シートのサンプル幅を5mmにして、フッ化ビニリデン系樹脂層−ポリアミド層間の剥離強度を引張試験機(オリエンテック社製「STA−1150」)を用いて測定した。後記表2中における「剥離せず」とは、剥離強度が15N/cmを超え、良好な接着状態であることを意味する。
燃料として、模擬燃料である「Fuel CE10」(イソオクタン/トルエン/エタノール=45/45/10(重量)混合物)を用い、この燃料にフッ化ビニリデン系樹脂層が接するようにフッ化ビニリデン系樹脂/ポリアミド二層シートを配置して、差圧式ガス・水蒸気透過率測定装置(GTRテック社製「GTR−30XAKC」)を用いて温度65度で燃料透過度[g/m2・day・atm]を測定した。
