摘要
介绍动态力学性能分析(DMA)仪的原理、应用和测试影响因素,从DMA数学模型分析储能模量、损耗模量、损耗因子偏差的原因。分析测试条件、氢键、并用胶对胶料动态力学性能的影响,并提出动态力学性能优化方案,推荐使用交联型白炭黑超级偶联剂SCBD。建议分析胶料动态力学性能时注意偏差,避免误判。
This paper introduced the principle, application and test factors of dynamic mechanical property analysis （DMA） apparatus, and analyzed the reasons which cause the deviation of storage modulus, loss modulus and loss factor from DMA mathematical model. The effects of test conditions, hydrogen bonding and blending on the dynamic mechanical properties were discussed, and improvement methods of dynamic mechanical properties were proposed. The cross-linkable super coupling agent SCBD for silica was a good candidate to improve the dynamic mechanical properties of rubber compound. In the analysis of test results, it was recommended to pay close attention to bias in order to avoid misjudgment.
