RUBBER COMPOSITION, RUBBER-METAL COMPOSITE USING THE SAME, AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition excellent in initial adhesion and moist-heat resistant adhesion and suitable to be used for a rubber-metal composite and a pneumatic tire using the same. SOLUTION: The rubber composition comprises (a) 100 pts.wt. of a diene rubber, (b) 0.2-0.8 pt.wt. (in terms of Co equivalent) of cobalt benzoate or cobalt (II) acetylacetonate and/or cobalt (III) acetylacetonate, and (c) 3-10 pts.wt. of a rosin and/or a derivative thereof. There are provided a rubber-metal composite and a pneumatic tire using the same. COPYRIGHT: (C)2007,JPO&INPIT
