A rubber hose for automobiles is provided to improve heat resistance, elongation and elasticity and to enhance the adhesive strength between a fluorocarbon rubber layer and a silicone rubber layer. A rubber hose for automobiles comprises an inner rubber layer which comprises a fluorocarbon rubber; a middle rubber layer which surrounds the inner rubber layer and is formed from the composition comprising 100 parts by weight of a silicone base comprising silicone crude rubber, a silica filler and a processing aid, and 0.5-2 parts by weight of a crosslinking agent comprising dicumyl peroxide, 2,5-dimethyl-2,5-di-(t-butylperoxy)-hexane, di-(2-t-butylperoxyisopropyl)-benzene or their mixture; a layered yarn layer which surrounds the middle rubber layer; and an outer rubber layer which surrounds the layered yarn layer and is formed from the composition comprising 100 parts by weight of a silicone base comprising silicone crude rubber, a silica filler and a processing aid, and 0.5-2 parts by weight of a crosslinking agent comprising di-(2,4-dichlorobenzoyl) peroxide. |
