Abstract
Description
本発明は、熱可塑性ゴム、熱可塑性ポリオレフィン樹脂及び化学的発泡剤を含有し、ロボットによる押出しにより押し出され得て、かつ発泡され得る、熱可塑性エラストマー組成物(TPE)に関する。
ロボットによる押出しは、熱可塑性ポリマーの寸法規制された形材の、自動取扱い単位装置(ロボット)の加工領域に配置された物品上への押出しを容易にする。押出機において溶融されたポリマーが、加熱された耐圧ホースにより、自動取扱い単位装置により案内され、押出しダイを備えた加熱された押出機ヘッドに供給される。そのポリマーは押し出され、物品上に堆積される。押出機のシリンダーと押出しノズル/ダイとの連接は、電気により加熱された耐高圧ホースによりなされる。耐高圧ホースは、操作温度において少なくとも約250バールの圧力に耐えなくてはならない。そのホースは、ホースに約200℃の温度に規則的な加熱を与える電気による加熱コイルを有する。一方、耐高圧ホースは、制限なく押出しダイの動きに従うことができ、ロボットの動きを邪魔しないように十分に柔軟性でなくてはならない。耐高圧ホースは、特定の状況において押出し操作に干渉することができる特定の捩り剛性を必然的に有する。
本発明は、得られた発泡体の溶融強度のような良好な化学的発泡性を維持しながらロボットによる押出しにより押し出され発泡されることができるように、低い粘度及びショアーA硬度並びに良好な流動性を有するTPV類を提供することを目的とする。
(A)(i).完全に硬化されたゴム及び
(ii).熱可塑性ポリオレフィンホモポリマー又はコポリマー
を含有し、約35乃至約85のショアーA硬度(5秒の遅れにおいてASTM D2240−02により測定される)を有する、熱可塑性ゴム、
(B)エチレンと酢酸ビニルのコポリマー(EVA)、C2乃至C12モノオレフィンのターポリマー及びそれらの混合物から成る群から選ばれ、約0.2乃至約10.0の溶融流量(230℃/2.16kg荷重においてASTM D1238−01により測定される)を有する熱可塑性樹脂及び
(C)化学的発泡剤
を含有する発泡性熱可塑性エラストマー組成物に関する。
熱可塑性ゴム(A)
成分(A)として本発明により用いられる熱可塑性ゴム(エラストマー)組成物は、熱可塑性及び弾性の両方の組み合わせ(熱可塑性エラストマー、TPE)を有する。熱可塑性ゴム組成物は、一般的に、エラストマーが熱可塑性ポリオレフィンの連続相内で離散した粒子相として均質に均一に分散されるように、熱可塑性ポリオレフィンをエラストマー組成物(ゴム)とブレンドすることにより得られる。加硫された組成物に関する初期の研究は、Gesslerへの米国特許第3,037,954号に見出され、静的加硫、並びに加硫性エラストマーが樹脂状の熱可塑性ポリマー中に分散され、そのポリマーブレンドを連続的に混合し、剪断する間に、前記エラストマーが硬化される動的加硫の技術が開示されている。得られた組成物(熱可塑性エラストマー加硫ゴム“TPV”)は、ポリプロピレンのような熱可塑性ポリマーの未硬化マトリックス中の、ブチルゴム、塩素化ブチルゴム、ポリブタジエン、ポリイソブテン等のような硬化されたエラストマーのミクロゲル分散体である。
i.未硬化ゴム及び
ii.熱可塑性ポリオレフィンホモポリマー又はコポリマー、及び
iii.従来の添加剤及び充填剤
を混合すること、
次に、均質なブレンドが得られるまで、その混合物を混練下に溶融させること
により製造され得る。加熱及び剪断の条件下での混合の間の硬化剤(架橋材又は加硫剤ともいう)のそのブレンドへの添加により、熱可塑性マトリックス中に分散された完全に硬化された(完全に加硫された又は完全に架橋されたともいう)ゴムが得られる。
約100gの熱可塑性エラストマー組成物の試料を計量し、微細な断片に切断(大きさ:0.5mm×0.5mm×0.5mm)する。密閉容器中で試料を30mlのシクロヘキサン中に23℃で48時間浸す。次に、その試料を取り出し、ろ紙上に置き、室温で一定重量に達するまで72時間以上乾燥させる。乾燥残査の重量から、ポリマー成分以外のすべてのシクロヘキサン不溶性成分(例えば、繊維充填剤、充填剤、顔料)の重量を差し引く。得られた値を「補正された最終重量(Y)」とする。一方、試料重量から、ポリマー成分以外のシクロヘキサン可溶性成分(例えば柔軟剤)の重量及びシクロヘキサン不溶性成分(例えば、繊維充填剤、充填剤、顔料)の重量を差し引く。得られた値を「補正された最初の重量(X)」とする。ゲル含量(シクロヘキサン不溶性成分の含量)は、下記の等式:
