Title:
The rubber composition for tires
Document Type and Number:
Japanese Patent JP6011152
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber composition for a tire, whose rolling resistance is reduced by blending a carbon black whose colloidal property is controlled and which is more improved in stability at handling in the case of becoming a tire than conventional levels.SOLUTION: A rubber composition for a tire is produced by blending 100 pts.wt. of diene rubber, total 1 to 50 pts.wt. of a novolak type phenol resin and a methylene donor, and 60 to 100 pts.wt. of a reinforcing filler containing 30 to 100 pts.wt. of a carbon black, and a mode diameter Dst in a mass distribution curve of a Stokes diameter of the carbon black aggregate is 145 nm or more, a nitrogen adsorption specific surface area NSA is 45 to 70 m/g, and a ratio of the nitrogen adsorption specific surface area NSA to an amount of iodine adsorption IA (unit:mg/g), NSA/I is 1.00 to 1.40.
