Description
真空および110℃での攪拌下で、123.9gのダイマー脂肪酸、1.1gのトリフェニルホスフィン、および57.3gのアジピン酸を、エポキシ含量が5.45当量/kgである658gの液状DGEBAエポキシ樹脂と、一定のエポキシ濃度2.85当量/kgが得られるまで5時間反応させた。その反応の終了後、追加の液状DGEBAエポキシ樹脂の118.2gをその反応混合物に加えた。
真空および110℃での攪拌下で、123.9gのダイマー脂肪酸、1.1gのトリフェニルホスフィン、および95.0gの2,2-ビス(4-ヒドロキシフェニル)プロパン(=ビスフェノール-A)を、エポキシ含量が5.45当量/kgである658gの液状DGEBAエポキシ樹脂と、一定のエポキシ濃度2.95当量/kgが得られるまで5時間反応させた。その反応の終了後、追加の液状DGEBAエポキシ樹脂の118.2gをその反応混合物に加えた。
真空および110℃での攪拌下で、123.9gのダイマー脂肪酸および28.3gのアジピン酸、1.1gのトリフェニルホスフィン、ならびに47.3gのビス(4-ヒドロキシフェニル)スルホンを、エポキシ含量が5.45当量/kgである658gの液状DGEBAエポキシ樹脂と、一定のエポキシ濃度2.85当量/kgが得られるまで5時間反応させた。その反応の終了後、追加の液状DGEBAエポキシ樹脂の118.2gをその反応混合物に加えた。
真空および110℃での攪拌下で、123.9gのダイマー脂肪酸、1.1gのトリフェニルホスフィン、および71.3gのビス(4-ヒドロキシフェニル)スルホンを、エポキシ含量が5.45当量/kgである658gの液状DGEBAエポキシ樹脂と、一定のエポキシ濃度2.82当量/kgが得られるまで5時間反応させた。その反応の終了後、追加の液状DGEBAエポキシ樹脂の118.2gをその反応混合物に加えた。
チキソトロープ剤Cを、特許出願EP1512019A1に詳細に記されているようにして、上記原料を用いたブロック化プレポリマー中で調製した。
真空および90℃での攪拌下、0.08gのジブチル錫ジラウレートが存在する中で、600.0gのポリエーテルポリオール(2000g/モル、OH価57mg/gKOH)を、140.0gのIPDIとイソシアナート含量が一定に留まるまで反応させ、イソシアナート末端のプレポリマーを生成させた。続いて遊離のイソシアナート基をカプロラクタム(2%過剰)でブロックした。
窒素および穏やかな加熱下で、68.7gのMDIフレークを、上記ブロック化プレポリマーの181.3g中で融解した。続いて、上記ブロック化プレポリマーの219.9g中に溶解した40.1gのN-ブチルアミンを、窒素および急速な攪拌下で、2時間以上かけて滴下しながら加えた。そのアミン溶液の添加が完了した後、その白色ペーストをさらに30分間攪拌した。続いて冷却した後、遊離のイソシアナート含量が<0.1%である柔らかな白色のペーストが得られた(尿素誘導体の割合、約21%)。
様々な接着剤組成物を表1に特定したように調製した。接着剤は、50℃で塗布した後、180℃のオーブン中で30分間硬化した。試験はすべて、接着剤が室温まで冷却した後にのみ実施した。
ガラス転移温度Tg(DIN EN ISO 6721-2/DIN EN 61006)
寸法が50×10mmの試験片を、2枚のテフロン(登録商標)フィルムの間に挟んで180℃で30分間硬化した2mm厚さの接着剤のシートから打ち抜いた。
寸法100×25×0.8mmの電気亜鉛めっき鋼(eloZn)を用い、接着剤が、0.3mmの層の厚さで表面積が25×10mmの試験片を用意した。それを180℃で30分間硬化した。引張り速度は、10mm/分とした。
寸法90×25×0.8mmの電気亜鉛めっき鋼(eloZn)を用い、接着剤が、0.3mmの層の厚さで表面積が25×30mmの試験片を用意した。それを180℃で30分間硬化した。衝突速度は、2m/秒とした。
表1の接着剤形成の結果は、高い衝撃強さ、高いガラス転移温度、および高い強度の組合せが、本発明による組成物を用いて実現できることを示している。本発明によらない例1と7は、実施例2および6と比較すると、チキソトロープ剤すなわち尿素誘導体の衝撃強さへのプラス効果を特にはっきりと示している。実施例2から6は、本発明によるエポキシ付加物の使用の効果の結果、衝撃強さの増加およびTgの上昇の両方を同時に実現することができ、一方で引張り剪断強さは変化しないで維持されることを示している。実施例9と10は、実施例2と6との比較であり、組成物が充填されていると充填されていないとに関わらず必要な特性を得ることができることを示している。実施例8と6は、コア/シェル型ポリマーの存在が、衝撃強さにプラスの効果を有しており、けれどもその効果は、チキソトロープ剤、すなわち尿素誘導体より小さいことを示している。
