Abstract
Official abstract text for this publication.
Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit surface discoloration of a rubber article. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one amine compound represented by formula (I) shown below. In formula (I), R 1 and R 2 each represent, independently of one another, an alkyl group having a carbon number of 1-10, an aralkyl group, or a phenyl group, and A represents an alkylene group having a carbon number of 6-30 that may include an interposed phenylene group.
First claim
Opening claim text (preview).
The invention claimed is: 1. An amine compound represented by formula (I) shown below where, in formula (I), R 1 and R 2 each represent a phenyl group, A represents an alkylene group having a carbon number of 6-30, and A does not include an interposed phenylene group. 2. An anti-aging agent for natural rubber and diene-based synthetic rubber-use comprising the amine compound of claim 1 . 3. A rubber composition comprising at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one amine compound represented by formula (II) shown below where, in formula (II), R 1 and R 2 each represent a phenyl group and m represents an integer of 8-16. 4. The rubber composition of claim 3 , wherein a blending amount of the at least one amine compound is in a range of from 0.2 parts by mass to 10 parts by mass relative to 100 parts by mass of the at least one rubber component. 5. A tire comprising a tire member comprising the rubber composition of claim 3 . 6. The tire of claim 5 , wherein the tire member is either or both of a tread and a sidewall.
