摘　　要：分别通过PRA2000橡胶加工分析仪和炭黑分散度仪对混炼胶和硫化胶中炭黑分散度进行测定,并对两种方法的测定结果进行对比。结果表明,通过橡胶加工分析仪测得的混炼胶中炭黑分散CBDI值与通过炭黑分散度仪测得的硫化胶中炭黑分散等级有很好的相关性,可根据胶料状态选择适宜的炭黑分散度测试表征方法。The dispersion of carbon black in the compound and vulcanizate was measured by PRA2000 Rubber Processing Analyzer(RPA)and carbon black dispersion meter respectively,and the measurement results of the two methods were compared.The results showed that the CBDI value of carbon black dispersion in the compound measured by RPA had a good correlation with the carbon black dispersion grade in the vulcanizate measured by the carbon black dispersion meter.The appropriate characterization method of carbon black dispersion could be selected according to the state of the compound.
