摘　　要：通过改变炭黑的比表面积,对比动态热机械分析仪(DMA)与橡胶加工分析仪(RPA)检测炭黑填充胎面胶的动态力学性能。结果表明,DMA与RPA测试的炭黑胶料的动态力学性能变化趋势相同,由于RPA制样简便,除低温下,可以采用RPA测试,减少DMA测试的工作量,降低测试成本。Dynamic thermomechanical analyzer(DMA) and rubber processing analyzer(RPA) were compared in the characterization of the dynamic mechanical properties of the tread compound filled with carbon black with different surface area. The results showed that the dynamic mechanical properties of carbon black filled compounds tested by DMA and RPA had the same trend. When the test temperature didn’t include low temperature range,RPA test was a better choice with reduced workload and test cost compared with DMA,since the sample preparation of RPA testing was simple and convenient.
