Abstract
A composite material made of metal and rubber for use in automotive tires, hoses, conveyor belts and the like. Its object is to increase its durability by improving the adhesion properties between the metal and the rubber. To accomplish this object, a metal provided with an improved plating layer is used in combination with a rubber having such a composition as to be suitable for use with the metal. More specifically, the composite material of metal and rubber contains as basic ingredients a metal plated with a copper-zinc-nickel ternary alloy and natural rubber or synthetic isoplene rubber containing sulfer and adhesion promotors such as cobalt salt of organic acid or silica, resorcin and hexamethylenetetramine. The rubber is vulcanized to be bonded to the metal.
