Abstract:
      The preparation of carbon black RE001 with high structure，high coloration strength and low polycyclic aromatic hydrocarbons （PAHs） and properties of natural rubber（NR） compound and NR/butadiene rubber（BR） blend filled with it were studied.The results showed that the main physical parameters of green carbon black RE001 and E7 were basically similar，but the PAHs content of carbon black RE001 was significantly lower than that of carbon black E7.Compared with carbon black N234，carbon black RE001 and E7 particles had significantly different sizes of microcrystals embedded on their surfaces，resulting in a rougher particle surface.The tensile strengths and elongations at break of NR compounds and NR/BR blends filled with carbon black N234，RE001 and E7 were not significantly different.The processing performance and wear resistance of NR compound and NR/BR blend filled with carbon black RE001 were the best，while the loss factor of NR/BR blend filled with carbon black RE001 was the smallest.Overall，the carbon black RE001 prepared by special processes not only met the high structure and high coloration strength requirements of low hysteresis and high wear resistant carbon black，but also achieves low PAHs content，which had good application value.
