Abstract
【解決手段】 ガラス転移温度の違うアクリル系のブロックポリマー、粘着付与剤、希釈剤および酸化防止剤を配合したホットメルト系感圧接着剤組成物及びこの接着剤を含む製品。
【選択図】なし
Description
本発明は、この要求を満足する。
さらに、本発明は、接着剤を含んでなる製品を提供する。接着剤の性質は工業用テープの製造、特に医療の用途 (例えば、皮膚適用) および不織物の用途において特に有用である。
今回、配合された接着剤中に低いレベルのアクリルブロックコポリマーを使用するとき、アクリルブロックコポリマーを使用して高い剪断応力、強力な粘着力および剥離力および低い粘度を有するホットメルト接着剤を得ることができることが発見された。必要な最終用途に要求される性質を得るために、異なる種類および量の粘着付与剤および/または希釈剤を、アクリルブロックコポリマーに配合する。
ポリマーブロックBは好ましくは少なくとも50質量%の量で存在する。特に好ましい態様において、A1およびA2はメチルメタクリレートであり、そしてBはn−ブチルアクリレートである。
例
試料の調製
すべての配合物はシグマブレードを有する600 gのブラベンダーミキサー中で調製した。各場合において、ミキサーを約163℃(ほぼ325 °F)に予熱した。比較試料E、FおよびGの調製において、2つの成分を均質になるまで一緒に混合した。比較試料A〜Dおよび試料1〜13の調製において、ポリマーおよび酸化防止剤をまず添加し、約5%の粘着付与剤および希釈剤と混合した。いったん均質になると、粘着付与剤を徐々に添加した。最後に、残りの希釈剤を添加した。
表1に記載するポリマーを使用して、実施例の試料配合物を調製した。
ABCP1、ABCP2、ABCP3、ABCP4、ABCP5およびABCP6は、特開平11−302617号に記載されているアニオン重合により製造したブロックコポリマーである。
レオメトリックス・ダイナミック・メカニカル・アナライザー (Rheometrics Dynamic Mechanical Analyzer) (RDA 700型) を使用して、弾性 (G’) および損失 (G”) 弾性率/温度を得た。リオス (Rhios) ソフトウェアバージョン4.3.2により、計器を制御した。約2 mmのギャップで分離された直径8 mmの平行板を使用した。試料を装入し、次いで約−100 ℃に冷却し、試験を開始した。プログラム試験は温度を5 ℃の間隔で増加させ、次いでソーク時間を各温度において10秒存在させた。試料を含有する対流炉を窒素で連続的にフラッシュした。周期数を10ラド/秒に維持した。試験開始における初期歪は0.05%であった (板の外側へりにおいて) 。ソフトウェアのオートストレイン (autostrain) オプションを使用して、試験全体を通じて正確に測定可能なトルクを維持した。ソフトウェアが許す最大の加えられた歪が50%であるように、オプションを構成した。オートストレインプログラムは、下記の手順を使用して正当化される場合、各温度増分における歪を調節した。トルクが200 g/cm以下である場合、歪を現在の値の25%だけ増加させた。トルクが1200 g/cm以上である場合、歪を現在の値の25%だけ減少させた。200および1200 g/cmの間のトルクにおいて、その温度増分において歪を変化させなかった。トルクおよび歪のデータから、剪断記憶または弾性率 (G’) および剪断損失弾性率 (G”) を計算する。また、それらの比G”/G’ (tanδとしても知られている) を計算した。
異なるレベルのポリマーを含有する接着剤配合物を比較した。使用したポリマーはABCP1であった。使用した粘着付与剤はKE−311 (95 ℃の軟化点を有する不均化、水素化ロジンエステル、Arakawa Chemical Industries, Co. から入手可能である) であった。Plasthall(商標) DIDA (アジピン酸ジイソデシル、C. P. Hall Co. から入手可能である) を希釈剤として使用した。
種々のレベルの異なるポリマー、粘着付与剤および希釈剤を含有する接着剤配合物を比較した。各配合物を調製するために使用した成分および量および生ずる粘度を表3に示す。
KE−100は、100 ℃の軟化点を有する不均化ロジンエステル (Arakawa Chemical Industries, Co. から入手可能である) である。
KE−311は、95 ℃の軟化点を有する不均化、水素化ロジンエステル (Arakawa Chemical Industries, Co. から入手可能である) である。
Foral 85は、85 ℃の軟化点を有する水素化ロジンエステル (Hercules Inc. から入手可能である) である。
Plasthall(商標)DTDA およびPlasthall(商標)DIDAは、それぞれ、アジピン酸ジトリデシルおよびアジピン酸ジイソデシル (C. P. Hall Co. から入手可能である) である。
Poly−G(商標)20−28およびPoly−G(商標)26−150は、それぞれ、分子量4000および775のポリプロピレングリコール (Arch Chemicals, Inc. から入手可能である) である。
Irganox 1010は、酸化防止剤 (Chiba Specialty Chemicals Corp. から入手可能である) である。
