Title (EN) COMPOSITE MOLDING AND PROCESS FOR PRODUCING THE SAME
(FR) MOULAGES COMPOSITES ET LEUR PROCEDE DE PRODUCTION
(JA) 複合成形体及びその製造方法
Abstract: front page image
(EN)A composite molding comprising a resin member of polyamide resin and, directly bonded thereto, a resin member of thermoplastic polyurethane resin, wherein the polyamide resin is constituted of a polyamide block copolymer containing polyether segment (A) having an imino group at at least its terminal. The polyamide resin may have free amino groups whose concentration is ≥ 10 mmol/kg. This composite molding can be produced by, for example, heating at least either a polyamide resin or a thermoplastic polyurethane resin and thereafter coupling them with each other. The thus obtained composite molding finds suitable application in shoe sole parts, industrially used rollers, etc. By virtue of this process, the polyamide resin member and thermoplastic polyurethane resin member having different properties can be easily bonded to each other fast in a straightforward manner.
(FR)L'invention porte sur un moulage composite comportant un élément de résine de polyamide et, lui étant directement fixé, un élément de résine thermoplastique de polyuréthane. La résine de polyamide, qui consiste en un copolymère bloc contenant un segment de polyéther (A) présentant un groupe imino à au moins l'un de ses terminaux, peut présenter des groupes amino libres dont la concentration est $m(G) à 10 mmol/kg. Le moulage composite peut s'obtenir par exemple en chauffant au moins une résine de polyamide ou une résine thermoplastique de polyuréthane puis en les liant ensemble. Ce moulage composite peut servir à la fabrication de semelles de chaussures ou de rouleaux à usage industriel. Ce procédé permet de lier ensemble facilement et directement deux résines aux propriétés différentes.
(JA) ポリアミド系樹脂で構成された樹脂部材と、熱可塑性ポリウレタン系樹脂で構成された樹脂部材とが直接接合した複合成形体において、前記ポリアミド系樹脂を少なくとも末端にイミノ基を有するポリエーテルセグメント(A)を含むポリアミドブロック共重合体で構成する。前記ポリアミド系樹脂の遊離のアミノ基濃度は、10mmol/kg以上であってもよい。前記複合成形体は、例えば、ポリアミド系樹脂及び熱可塑性ポリウレタン系樹脂の少なくともいずれか一方を加熱し、両者を接合することにより製造できる。得られた複合成型体は靴底部品、産業用ローラーなどに適する。このような方法では、簡便に、互いに性質の異なるポリアミド系樹脂部材と熱可塑性ポリウレタン系樹脂部材とを直接的かつ強固に接合できる。
