Title:
RUBBER COMPOSITION
Document Type and Number:
Japanese Patent JP2014234448
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber composition capable of simultaneously realizing, at advanced dimensions, grippability on a dry road surface, grippability on a wet road surface, and abrasion resistance.SOLUTION: The provided rubber composition includes: a rubber component including, as a modified conjugated dienic polymer, a conjugated dienic polymer including at least one type of functional group selected from the group consisting of substituted amino groups and cyclic amino groups; a silica-containing filler; and a low-softening-point resin having a softening point of 145°C or below. The ratio of the modified conjugated dienic polymer with respect to the rubber component is 10-40 wt.%. The mixing ratio of the filler with respect to 100 parts.wt. of the rubber component is 80-110 parts.wt. The mixing ratio of the low-softening-point resin with respect to 100 parts.wt. of the rubber component is 5.0-40 parts.wt. The ratio of silica with respect to the filler is 60-95 wt.%.
