Title:
RUBBER COMPOSITION FOR TIRES AND CONSTRUCTION VEHICLE TIRE USING THE SAME
Document Type and Number:
Japanese Patent JP2021187900
Kind Code:
A
Abstract:
To provide a rubber composition for tires capable of simultaneously improving a storage modulus and heat build-up properties.SOLUTION: The rubber composition for tires is obtained by blending 100 pts.mass of a diene rubber containing 65-100 pts.mass of at least one selected from the group consisting of a natural rubber and a synthetic isoprene rubber and 0-35 pts.mass of a styrene-butadiene copolymer rubber with: 40-80 pts.mass of carbon black having a nitrogen adsorption specific surface area (N2SA) of 85-120 m2/g; 5-35 pts.mass of silica having a nitrogen adsorption specific surface area (N2SA) of 140-200 m2/g; and 0.5-10 pts.mass of a phenolic resin having at least one ethyleneamine-derived structural unit represented by -(NH-C2H4)- in the molecule.SELECTED DRAWING: None
