Document Type and Number:
Japanese Patent JP6421614
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To overcome a problem that abrasion resistance is reduced with a method of blending a hollow polymer for enhancing on-ice performance of a studless tire conventionally and a problem that elongation s reduced and abrasion resistance is reduced with a method of blending a dispersion for carbon black.SOLUTION: The above described problem is solved by a rubber composition for winter tire by blending 100 pts.mass of a diene rubber having average Tg-100°C to -75°C, 30 to 200 pts.mass of a reinforcement filler, 0.1 to 20 pts.mass of a compound having a structure of quinones and a structure of sulphonic acid and a salt thereof in a molecule and/or a compound having a structure of quinones and a structure of thiosulfate or a salt thereof in a molecule and 20 pts.mass or more of a softening agent, where 30 mass% or more is carbon black and 10 mass% or more is silica in the reinforcement filler.SELECTED DRAWING: None
