| 中文摘要: |
| 研究不同分子结构的功能树脂对以天然橡胶及其与丁苯橡胶的并用体系为基体的阻尼橡胶材料性能的影响，探索提高阻尼橡胶材料的阻尼性能的方法。通过功能树脂调整阻尼橡胶材料的损耗因子（tanδ）曲线是在保持其高弹性的同时提高其阻尼特性的一种有效方法。不同分子结构的树脂与橡胶相容性的差异对于调整不同温度范围内使用的橡胶阻尼材料的tanδ曲线具有重要意义。试验结果表明，通过树脂分子结构的调控，可以实现特定温度范围内橡胶阻尼材料的tanδ的增大，从而提升橡胶阻尼制品的阻尼性能。 |
| 英文摘要: |
| The effects of functional resins with different molecular structures on the properties of
damping rubber materials based on natural rubber（NR） and its blend with styrene butadiene rubber（SBR）
were studied，and the methods to improve the damping properties of damping rubber materials were explored.
Adjusting the loss factor（tanδ） curves of damping rubber materials by functional resins was an effective
method to maintain their high elasticity and improve their damping properties. The difference in compatibility
between resins with different molecular structures and rubber had great significance for adjusting the tanδ
curves of damping rubber materials used in different temperature ranges. The test results showed that the
tanδ of damping rubber materials in a specific temperature range could be improved by adjusting the resin
molecular structures，so as to improve the damping properties of damping rubber products. |
