Abstract
A rubber composition for adhering to steel cords, having excellent heat-resistant adhesion and moist heat-resistant adhesion, as well as initial adhesion, and performance at a level comparable to or higher than that of the related art in resistance to rubber fracture, is made from components (A) and (B), which are blended to 100 weight parts of rubber components containing natural rubber and/or diene synthetic rubber, wherein component (A) is a mixture of a compound containing nickel and a compound containing molybdenum; or a compound containing nickel and molybdenum simultaneously, in a metal-converted amount of 0.01 to 10 weight parts; and component (B) is a mixture of (b1), which is 0.2 to 20 weight parts of hexamethylenetetramine or a melamine derivative, and (b2), which is 0.1 to 10 weight parts of at least one selected from the group consisting of phenol resins, resorcin, resorcin derivatives, and cresol resins.
