Abstract
This invention provides a rubber hose in which an outer rubber layer is laminated by means of extrusion on the outer peripheral surface of an inner rubber layer, wherein: the inner rubber layer is a fluororubber layer 2; the outer rubber layer is a reinforcing yarn-woven silicone rubber layer 1 having reinforcing yarns woven therein; an intermediate rubber layer having an adhesive component for the adhesion with the fluororubber layer is provided between the fluororubber layer 2 and the reinforcing yarn-woven silicone rubber layer 1; and the intermediate rubber layer is an intermediate silicone rubber layer 3 having a hardness lower than those of the reinforcing yarn-woven silicone rubber layer and the fluororubber layer; and a method for manufacturing the rubber hose. Further, this invention provides a rubber hose in which an outer rubber layer is laminated by means of winding on the outer peripheral surface of an inner rubber layer, wherein: the inner rubber layer is a fluororubber layer 5; the outer rubber layer is a fabric-reinforced silicone rubber layer 4; an intermediate rubber layer containing an adhesive component for the adhesion with the fluororubber layer 5 is provided between the fluororubber layer 5 and the fabric-reinforced silicone rubber layer 4; and the intermediate rubber layer is an intermediate silicone rubber layer 6 having a hardness lower than that of the fabric-reinforced silicone rubber layer; and a method for manufacturing the rubber hose.
