Rubber composition for tire-tread having high frictional force on ice and pneumatic tire using same |
摘要 |
1. A rubber composition for a tire tread containing: (i) 100 parts by weight of a diene rubber, and (ii) 1 to 20 parts by weight of an elastic gas-encapsulated thermoplastic resin hollow particle having a particle size of 5-300 mu m, which is obtained by expanding, upon heating during vulcanization, a thermally expansible thermoplastic resin containing an encapsulated liquid or solid substance capable of generating a gas by vaporization, decomposition or chemical reaction upon heating to form the hollow-type expanded particle and, optionally containing (iii) 1 to 20 parts by weight of a short fiber or (iv) 1 to 20 parts by weight of a hard particle.
