<P>PROBLEM TO BE SOLVED: To provide a rubber blended material in which the grip performance of a rubber decreased due to T-DAE oil is improved to the same level as in use of DAE oil by blending an alkylphenol resin in the rubber. <P>SOLUTION: The rubber composition includes 100 pts.wt. of a rubber component, ≥10 pts.wt. of T-DAE oil, ≥2 pts.wt. of an alkylphenol resin and 30 to 100 pts.wt. of a filler. The alkylphenol resin is of a novolac type, and contains alkylphenols whose alkyl chain has ≥2 and ≤10 carbon atoms, and has a softening point of 70 to 120°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
