Abstract:
      The effects of the advance preparation methods of powdered carbon black（hereinafter referred to as carbon black） on the properties of wet mixed（gelled） compounds were studied and compared with traditional dry mixed compound.The results showed that the properties of carbon black wet mixed compounds were significantly better than those of dry mixed compound，among them the comprehensive performance of wet mixed compound with ground carbon black was the best.The comprehensive performance of wet mixed compound with non granulated carbon black was not significantly improved compared to dry mixed compound due to its extremely light weight and difficult to be dispersed.Ground carbon black and sieving and screened and crushed carbon black could achieve gel with natural rubber latex in a short time，and their wet mixing efficiencies were higher.
