Abstract
The present invention provides a heat resistant fuel hose comprising a rubber inner pipe with an inner layer and an outer layer in the inner pipe. The inner layer of the inner pipe comprises a hydrogenated acrylonitrile butadiene rubber (H-NBR) that is mixed with zinc oxide (ZnO) and magnesium oxide (MgO) as acid acceptors and is peroxide vulcanized. The outer layer of the inner pipe comprises an epoxy cross-linking type acrylic rubber (ACM) that has been vulcanized bonded to the inner layer of the inner pipe. The inner layer and outer layer of the inner pipe of the heat resistant fuel hose of the present invention are strongly bonded, and the rubber inner pipe has excellent heat resistance.
