摘　　要：对裂解炭黑(CBp)进行改性,并研究改性CBp在乘用轮胎胎侧胶中的应用。结果表明:在胎侧胶中,以CBp等量替代50%的炭黑N375后,胶料的物理性能明显降低;以物理改性(气流粉碎)CBp等量替代50%的炭黑N375,胎侧胶的物理性能有所降低;以化学改性(改性剂为马来酸酐-乙二醇-双环戊二烯共聚物)CBp等量替代50%的炭黑N375,胎侧胶的物理性能变化不大,滚动阻力降低;在胎侧胶中可以用化学改性CBp替代一定比例的炭黑N375,在降低胶料成本的同时有利于环保。Pyrolysis carbon black(CBp) was modified,and the application of modified CBp in passenger tire sidewall compound was studied(replacing 50% carbon black N375 with the same amount of CBp).The results showed that when the CBp was unmodified CBp,the physical properties of the sidewall compound decreased significantly.When the CBp was physically modified(air flow crushing),the physical properties of the sidewall compound were still reduced.However,when the CBp was chemically modified by using maleic anhydride-ethylene glycol-dicyclopentadiene copolymer,the physical properties of the sidewall compound showed little change,and the rolling resistance decreased.Chemically modified CBp could be used to replace a certain proportion of carbon black N375 in the sidewall compound,which was beneficial to environmental protection while reducing compound cost.
