| 发明名称 | Rubber composition and run-flat tire using same | ||
| 摘要 | The present invention can provide a rubber composition, in which all of strength at break, low heat-build up property, run-flat durability and low fuel consumption can be improved since the rubber composition comprises 5 to 120 parts by weight of flake-like graphite having an average aspect ratio of 3 to 80 and an average particle diameter of 2 to 80 μm on the basis of 100 parts by weight of a diene rubber component, and a run-flat tire using the rubber composition. | ||

| 主权项 | 1. A rubber composition, comprising 5 to 120 parts by weight of a flake-like graphite having an average aspect ratio of 3 to 80 and an average particle diameter of 2 to 80 μm on the basis of 100 parts by weight of a diene rubber component; wherein said diene rubber component comprises 20 to 80% by weight of a butadiene rubber; and wherein the graphite is layered graphite having a crystal structure of hexagonal, plate-like form. | ||
