FIBER-REINFORCED RUBBER HOSE

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced rubber hose having excellent adhesiveness of an ethylene acrylic copolymer rubber and a epichlorohydrine rubber to fibers and suitably usable under high temperature atmosphere such as in an engine room of an automobile. SOLUTION: In this fiber-reinforced rubber hose, a reinforcement layer is installed between an inner layer rubber layer and an outer layer rubber layer at least one of which is formed of the ethylene acrylic copolymer rubber or a epichlorohydrine rubber. The reinforcement layer is formed of aramid fiber cords formed by adding a treatment agent containing a compound formed by co-condensing resorcine-firmalin-ritrile-butadiene rubber latex (RFL), p-chlorophenol, and resorcin with formaldehyde to fiber cords to which polyepoxide compound is adhered after the aramid fibers to which the polyepoxide compound is adhered are twined beforehand or to which the polyepoxide compound is adhered after the aramid fibers are twined.
