Mehrschichtiger Gummischlauch und Verfahren zu seiner Herstellung
摘要
<p>A multi-layer rubber hose in which a fluorinated rubber (FKM) layer and a nitrile rubber (NBR) layer adjacent thereto have been vulcanization-adhered to each other. The FKM layer is formed from the vulcanizate of an FKM compound containing a ternary FKM as a polymer component. The vulcanization system is an organic polyol system and a quaternary ammonium salt, and the vulcanization induction time (T10) satisfies the following equation, 4 minutes </=T10+determined vulcanization temperature -170 DEG C.) minutes/10 DEG C.</=7 minutes. The NBR layer is formed from the vulcanizate of the NBR compound, and the NBR comound is a stock rubber into which a functional group having an active hydrogen has been introduced. The vulcanization system is an oragnic peroxide system. The multi-layer rubber hose of the presnt invention is suitable as a fuel hose for cars and has a high resistance to gasohol.</p>
