PROBLEM TO BE SOLVED: To improve more vibration-proof characteristic and noise-proof characteristic of vibration-proof material having foamed synthetic resin and vibration-proof rubber combined to each other as compared with that of conventional vibration-proof material.SOLUTION: This invention relates to vibration-proof material 10 comprising a flat plate-like foamed synthetic resin body 1 and vibration-proof rubber 2 arranged to pass through this foamed synthetic resin body 1 in its thickness direction, the vibration-proof rubber 2 is formed by vulcanizing vibration-proof rubber material containing relative to 100 mass% of rubber component including natural rubber, 30 to 50 mass% of carbon black, 0.3 to 0.7 mass% of N-p-toryl thio phthalic imide, 0.7 to 2.5 mass% of sulfur, 0.2 to 4.0 mass% of tetrakis [2-sebacate] thiuram disulfide, and 0.2 to 4.0 mass% of N-tert-butyl-2-benzothiazolyl sulfenic amide.SELECTED DRAWING: Figure 1 |
