VIRBRATION-DAMPING MATERIAL AND PRODUCTION METHOD THEREFOR
A highly durable vibration-damping material is provided. The inventive vibration-damping material comprises a thermoplastic polyurethane elastomer as a major component, and carbon black, wherein the carbon black is dispersed essentially only in a soft segment of the thermoplastic polyurethane elastomer.
1 . A vibration-damping material comprising:
a thermoplastic polyurethane elastomer as a major component; and
carbon black;
wherein the carbon black is dispersed essentially only in a soft segment of the thermoplastic polyurethane elastomer.
2 . The vibration-damping material according to claim 1 , wherein the carbon black is present in a proportion of 5 to 50 parts by weight based on 100 parts by weight of the thermoplastic polyurethane elastomer.
3 . A production method for the vibration-damping material according to claim 1 , the method comprising the step of kneading a thermoplastic polyurethane elastomer and carbon black at a temperature of 20° C. to 100° C.
4 . A production method for the vibration-damping material according to claim 2 , the method comprising the step of kneading a thermoplastic polyurethane elastomer and carbon black at a temperature of 20° C. to 100°.
