<P>PROBLEM TO BE SOLVED: To provide a rubber composition enhanced in adhesion durability to a metal reinforcing material such as a steel cord or the like used for a rubber product such as a tire, an industrial belt or the like and in a low-heat buildup property. <P>SOLUTION: The rubber composition comprises a rubber component comprising a low-heat buildup natural rubber, sulfur and a specific sulfenamide vulcanization accelerator. The composition contains 0.1-10 pts.mass of the sulfenamide vulcanization accelerator based on 100 pts.wt. of the rubber component. Preferably, the rubber composition contains 0.03-3 pts.mass, in terms of cobalt, of a cobalt salt of an organic acid based on 100 pts.mass of the rubber component. <P>COPYRIGHT: (C)2012,JPO&INPIT |
