Title (EN) AIR-IMPERMEABLE FILM AND METHOD FOR PRODUCING PNEUMATIC TIRE
(FR) FILM IMPERMÉABLE À L'AIR ET PROCÉDÉ DE PRODUCTION DE BANDAGE PNEUMATIQUE
(JA) 耐空気透過性フィルム及び空気入りタイヤの製造方法
Abstract:
(EN) A method for producing an air-impermeable film according to one embodiment comprises melt-kneading and thereby dynamically crosslinking a thermoplastic resin, and a rubber composition having a melt viscosity lower than that of the thermoplastic resin at 230°C and a vulcanization rate of 0.70 dN·m/min or higher at 200°C, to obtain a dynamically crosslinked product in which the thermoplastic resin is in a continuous phase, and the rubber composition is in a dispersed phase. As a result, an air-impermeable film having excellent durability is obtained.
(FR) Selon un mode de réalisation, la présente invention concerne un procédé de production d'un film imperméable à l'air consistant à malaxer à l'état fondu et de ce fait à réticuler de manière dynamique une résine thermoplastique, et une composition de caoutchouc ayant une viscosité à l'état fondu inférieure à celle de la résine thermoplastique à 230 °C et une vitesse de vulcanisation de 0,70 dN·m/min ou plus à 200 °C, afin d'obtenir un produit réticulé de manière dynamique, la résine thermoplastique étant dans une phase continue, et la composition de caoutchouc étant dans une phase dispersée. Par conséquent, un film imperméable à l'air présentant une excellente durabilité est obtenu.
(JA) 実施形態に係る耐空気透過性フィルムの製造方法は、熱可塑性樹脂と、前記熱可塑性樹脂よりも230℃での溶融粘度が低くかつ200℃での加硫速度が0.70dN・m/分以上であるゴム組成物と、を溶融混練し動的架橋させることにより、前記熱可塑性を連続相とし、前記ゴム組成物を分散相とした動的架橋体を得ることを含むものである。これにより、耐久性に優れた耐空気透過性フィルムが得られる。
