<p>PROBLEM TO BE SOLVED: To reduce dynamic magnification without impairing heat resistance.SOLUTION: The rubber composition for vibration-proof rubber contains 10-100 pts.mass of carbon black based on 100 pts.mass of a diene-based rubber component including natural rubber, and 0.3-5 pts.mass of a compound represented by formula (1) based on 100 pts.mass of carbon black. In the formula, Rrepresents a hydrogen atom, a 1-6C alkyl group or alkenyl group, or a 3-6C cyclic alkyl group or alkenyl group; A represents NH, NR, O, or S; Rrepresents a 1-6C alkyl group or alkenyl group, or a 3-6C cyclic alkyl group or alkenyl group; n represents an integer of 1-6; and x represents an integer of 1-4.</p> |
