RUBBER COMPOSITION COMPRISING SILICA COMPOUNDED THEREIN

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition comprising silica compounded therein, eliminating problems of retarded vulcanization and a viscosity increase according to compounding of a large amount of the silica and improving the vulcanization physical properties such as tensile physical properties. SOLUTION: The rubber composition is obtained by compounding 100 pts.wt. of at least one kind of diene rubber with 10-90 pts.wt. of the silica and 0.2-10 pts.wt. of ammonium benzoate.
