Abstract:
      Carbon black/NR composite was prepared by wet continuous mixing process，and compared with traditional dry mixing process.The physical properties of the composite and carbon black dispersion were studied.The results showed that，the combination of wet process and continuous mixing process could achieve green environmental mixing of the composite.Compared with the compound used by dry mixing process，the Mooney viscosity of the compound used by continuous wet mixing process increased ，and the t90 shorten.Compared with the vulcanizate used by the traditional dry mixing process，the tensile strength，wear resistance and cutting resistance of the vulcanizate used by the wet continuous mixing process increased，the Payne effect and the loss factor at 60 ℃ decreased，so that its comprehensive physcial properties were excellent.The carbon black dispersion of the vulcanizate used by continuous mixing process was uniform，large aggregates did not appear，the carbon black dispersion grade X was 7.9，and the average aggregate size was 3.4 μm.
