| Abstract: |
| Graphite was added into SE2155 damping silicone rubber material by means of open mixing，
and the physical properties and dynamic mechanical properties of graphite/SE2155 damping silicone rubber
composite were studied. The results showed that，with the increase of graphite amount，the processing
properties of graphite/SE2155 damping silicone rubber compound were deteriorated，the tensile strength of
graphite/SE2155 damping silicone rubber vulancinate increased first and then decreased，and it reached 9. 2
MPa when graphite amount was 10 phr. Graphite/SE2155 damping silicone rubber vulcanizate had better
comprehensive properties when graphite amount was 5 phr. When graphite amount did not exceed 20 phr，the
addition of graphite did not change the changing trend of the modulus and damping characteristics of SE2155
damping silicone rubber with temperature，frequency and strain. |
