<P>PROBLEM TO BE SOLVED: To provide a heat-resistant air hose achieving cost reduction by using a versatile rubber and having excellent heat resistance and interlayer adhesiveness. <P>SOLUTION: The heat-resistant air hose includes an inner layer 1 and an outer layer 2 formed on an outer circumference of the inner layer. The inner layer 1 is formed of an acrylic rubber composition containing components of (a) an acrylic rubber and (b) carbon black having a hydroxyl group on the surface thereof. The outer layer 2 is formed of an ethylene-propylene rubber composition containing components of (A) an ethylene-propylene rubber and (B) a crosslinking agent. The inner layer 1 and the outer layer 2 are adhered to each other by using a silane-based adhesive. <P>COPYRIGHT: (C)2013,JPO&INPIT |
