Method for manufacturing fuel hose and ultraviolet crosslinking composition used therefor

摘要

A method for manufacturing a fuel hose which can efficiently produce heat-resistant and flexible fuel hoses. The method for manufacturing a fuel hose forms a protector layer on an outer peripheral surface of a resinous inner layer, and includes the steps of extruding an ultraviolet crosslinking composition for a protector layer that contains the following components A to D, on the outer peripheral surface of the resinous inner layer; and subsequently, irradiating ultraviolet rays to polymerize the ultraviolet crosslinking composition, thus forming the protector layer:(A) ethylene-propylene-diene rubber;(B) acrylate-based monomer;(C) silica; and(D) photopolymerization initiator.
