中文摘要:
      采用Brabender 转矩流变仪研究高耐磨炭黑（HAF）填充型粉末SBR[P（SBR/HAF）]和块状SBR（SBR/HAF）在较宽的混炼条件范围内（转速40～80 r·min-1，循环油温50～100 ℃）于密炼机中混炼的流变特性，讨论了混炼条件对胶料混炼流变性能的影响。结果表明，在试验的转子转速和循环油温范围内，P（SBR/HAF）比SBR/HAF表现出较高的表观剪切粘度，其对混炼时间的依赖性为SBR/HAF的50%～70%，但两者对转子转速和循环油温的敏感性相近。
英文摘要:
      The effect of different mixing conditions （rotor speed：40～80 r·min-1；temperature of circulating oil：50～100 ℃）on the rheological behavior of HAF black filled powdered SBR [P（SBR/HAF）]was investigated by using Brabender torque rheometer and compared to that of HAF black filled bale SBR （SBR/HAF）.It was found from the test results that at above rotor speeds and mixing temperatures，the higher apparent shear viscosity and 30%～50% lower dependence on mixing time were observed for P（SBR/HAF） when compared to those for SBR/HAF，while two kinds of mixes showed similar dependence on rotor speed and mixing temperature.
