摘　　要：研究不同添加量的白炭黑对天然橡胶/顺丁橡胶复合材料性能的影响。结果表明:当白炭黑加入量为10~60份时,随着白炭黑用量的增多,NR/BR复合材料的焦烧时间和正硫化时间逐渐延长,最大扭矩逐渐增大;硬度、拉伸强度、100%定拉伸强度,撕裂强度逐渐增大,断裂伸长率和耐磨性能先增大后减小;干式防滑性能随着白炭黑用量的增加呈下降趋势,湿式防滑性能随白炭黑用量的增加变化不明显。The effects of different amounts of silica on the properties of natural rubber/cis-polybutadiene rubber composites were investigated.The results showed that when the amount of silica was 10~60 phr,with the increase of silica content,the scorch time and positive vulcanization time and the maximum torque of NR/BR composites gradually increased.Hardness,tensile strength,stress at 100%elongation,and tear strength gradually increased.Elongation at break and wear resistance first increased and then decreased.The dry skid performance decreased with the increase of the amount of silica,and the wet skid performance did not significantly change with the increase of the amount of silica.
