Title:
耐空気透過性フィルム及び空気入りタイヤの製造方法
Document Type and Number:
Japanese Patent JP6676366
Kind Code:
B2
Abstract:
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.
