| 研究不同品种炭黑混炼胶在不同测试条件下的加工流变性能。结果表明：炭黑N550的混炼加工性能好，炭黑N134混炼时更易聚集，分散差；混炼胶的门尼粘度和结合橡胶含量随着炭黑结构的增高和比表面积的增大而增大，与炭黑CDBP吸油值的相关性好，相关因数均为0.95；混炼胶的Payne效应与炭黑比表面积和应力松弛面积的相关性好，相关因数均为0.98；混炼胶的挤出胀大比受混炼胶中结合橡胶和包容胶含量的双重影响。 |

| Abstract：The processing rheological properties of the compounds filled with different types of carbon
black under various testing conditions were studied. The results showed that carbon black N550 had good
mixing performance，while carbon black N134 was more likely to aggregate and had poor dispersion in
the mixing process. The Mooney viscosity and bound rubber content of the compound increased with the
increase of carbon black structure and specific surface area，and they had good correlations with the CDBP
oil absorption value of the carbon black with a correlation coefficient of 0. 95. In addition，the Payne effect
of the compound had a good correlation with the specific surface area and stress relaxation area of the carbon
black，and the correlation factor was 0. 98. The extrusion swelling ratio of the compound was affected by the
content of both bound rubber and trapped rubber. |
