| Abstract: |
| The brominated butyl rubber（BIIR）/butadiene rubber（BR）/C5 resin composite damping material was prepared by mechanical blending of BIIR/BR in the first stage mixing，and then adding different amounts of C5 resin into the blend.The influence of the amount of C5 resin on the properties of composite damping materials and the tem erature dependence of damping properties were studied. The results
showed that，when the amount of C5 resin was 20 phr，the vulcanization characteristics，physical properties，aging resistance，damping property and low temperature resistance of the BIIR/BR/C5 resin composite damping material were better. |
