Abstract
Official abstract text for this publication.
Provided is a rubber composition for a tire tread, which includes 1 or greater parts by mass and less than 20 parts by mass of a millable silicone rubber compound per 100 parts by mass of a diene rubber, wherein the millable silicone rubber compound has a storage modulus of 0.3 to 10 kPa at a 450% shear strain at 110° C. and a glass transition temperature and a plasticity with a relationship: 14000<(273+Tg)×Pn<82000, where Tg is the glass transition temperature (° C.) and the Pn is the plasticity at 23° C.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition for a tire tread comprising: 1 or greater parts by mass and less than 20 parts by mass of a millable silicone rubber compound per 100 parts by mass of a diene rubber, wherein the millable silicone rubber compound comprises from 1 to 50 mass % of silica and/or carbon black, and the millable silicone rubber compound has a storage modulus of 0.3 to 10 kPa at a 450% shear strain at 110° C. and has a glass transition temperature and a plasticity with a relationship: 14000<(273+Tg)×Pn<82000 where Tg is the glass transition temperature (° C.) and Pn is the plasticity at 23° C. 2. The rubber composition according to claim 1 , wherein the rubber composition, after vulcanization, has a surface roughness (Ra) measured by a contact-type surface roughness measurement instrument of from 1 to 30 μm. 3. The rubber composition according to claim 1 , further comprising from 0.2 to 20 parts by mass of a thermally expandable microcapsule per 100 parts by mass of the diene rubber. 4. The rubber composition according to claim 3 , wherein the rubber composition comprises a master batch comprising a mixture of the millable silicone rubber compound and the thermally expandable microcapsule. 5. The rubber composition according to claim 1 , further comprising a peroxide-type crosslinking agent. 6. The rubber composition according to claim 2 , further comprising from 0.2 to 20 parts by mass of a thermally expandable microcapsule per 100 parts by mass of the diene rubber. 7. The rubber composition according to claim 6 , wherein the rubber composition comprises a master batch comprising a mixture of the millable silicone rubber compound and the thermally expandable microcapsule. 8. The rubber composition according to claim 7 , further comprising a peroxide-type crosslinking agent.
