Abstract A new modification method of pyrolysis carbon black CBp was developed. Firstlythe CBp was upgraded by hybridization with cellulose via ball milling of CBp and micro fibrillated cellulose MFC and then spray dried to obtain the hybrids CNCH. The effect of CBp/MFC mass ratio on the structural morphology of the prepared CNCH and its properties of reinforced natural rubber was investigated in detail. A series of studies have shown that co-ball milling of CBp/MFC can efficiently achieve the refinement of CBpnanosizing of MFC and hybridization of bothand the obtained CNCH has a special chain bead-like morphologyand with the increase of MFC content in the CNCH fractionespecially when the mCBpmMFCis 4∶1compared with CBpthe CNCH-reinforced NR has more excellent vulcanization characteristicsmechanical properties and higher wear resistance than CBp. This implies that CNCH has obvious advantages as a reinforcing filler for tire rubber compounds. In additionthe upgrading process is simpleenvironmentally friendly and suitable for industrial applications.
