摘　　要：研究几种牌号炭黑活性的测试方法。结果表明:对于炭黑N326,N134,N115,N220和N234,相对活性、红外光谱、结合胶含量和物理性能4种方法测试的炭黑活性具有高度一致性。相对活性大的炭黑,红外光谱活性基团吸收峰明显,其胶料结合胶含量大,物理性能和耐磨性能好。建议有条件的企业测试炭黑的相对活性和红外光谱,条件有限的企业测试结合胶含量。Test methods for the activity of several kinds of carbon black were studied. The results showed that, for carbon black N326, N134, N115, N220 and N234, the results tested by four methods including relative activity test, infrared spectroscopy, bound rubber content and physical properties of the filled compound were highly consistent. Carbon black with higher relative activity had more obvious absorption peak of active group in infrared spectrum, and the filled compound had higher bound rubber content, better physical properties and wear resistance. Companies with better testing capability could use the methods of relative activity test and infrared spectroscopy of carbon black, otherwise the test of the bound rubber content of filled compound could be applied.
