Abstract
This invention is directed to a rubber laminate that produces a sufficient bonding strength between a FKM layer and a NBR layer. The FKM layer is made of a FKM compound containing a polyol vulcanization system in which a vulcanization accelerator is incorporated in an amount more than usual, or a FKM compound of peroxide vulcanization system in which a vulcanizing agent and accelerator used for the polyol vulcanization system is incorporated along with the peroxide vulcanization system. The NBR layer is made of a NBR compound incorporated with an oxide or hydroxide of a metal selected from Goups II to IV of the Periodic Table such as calcium hydroxide in an amount more than usual. The rubber laminate of this invention is suitable for rubber hoses and rubber diaphragm.
