PURPOSE: A rubber composition for carcass is provided to improve fatigue property caused by heat resistance and aging property by using a dione compound including 2,3-dihydronaphthalene-1,4-dione as a vulcanization accelerator. CONSTITUTION: A rubber composition for carcass comprises a base rubber 100.0 parts by weight and a dione compound 0.1-1.0 parts by weight as a vulcanization accelerator. The dione compound is 2,3-dihydronaphthalene-1,4-dione. The base rubber is natural rubber or a mixed rubber of natural rubber and butadiene rubber. The mixed rubber comprises natural rubber and synthetic rubber in a weight ratio of 1:9~9:1. |
