| 中文摘要: |
| 通过开炼方式在SE2155阻尼硅橡胶材料中加入石墨，研究石墨/SE2155阻尼硅橡胶复合材料的物理性能和动态力学性能。结果表明：随着石墨用量的增大，石墨/SE2155阻尼硅橡胶混炼胶的加工性能变差，硫化胶的拉伸强度先增大后减小；在石墨用量为10份时，硫化胶的拉伸强度达到9.2 MPa；石墨用量为5份时，石墨/SE2155阻尼硅橡胶硫化胶的综合性能较好，石墨用量超过20份，石墨的加入不改变SE2155阻尼硅橡胶材料模量及阻尼特性随温度、频率及应变变化的趋势。 |
| 英文摘要: |
| 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. |
