%X 试验研究顺丁橡胶（BR）和白炭黑对炭黑/天然橡胶（NR）复合材料性能的影响。结果表明：与炭黑/NR复合材料相比，炭黑/NR/BR胶料的焦烧时间略有缩短，交联程度增大，硫化胶的300%定伸应力增大，压缩生热降低，抗切割性能下降，耐磨性能提高，滚动阻力减小；炭黑/白炭黑/NR胶料的交联程度减小，硫化胶的拉断伸长率和撕裂强度明显增大，压缩生热略有升高，抗切割性能和耐磨性能提高，滚动阻力增大（须通过加入偶联剂予以改善）。;The effects of BR and silica on the properties of carbon black/NR composite were experimentally investigated.The results showed that，compared to carbon black/NR composite，the scorch time of carbon black/NR/BR compound was reduced slightly，the crosslink degree increased，the modulus at 300% elongation of the vulcanizate increased，the compression heat build-up and cut resistance was decreased，the abrasion resistance was improved and rolling resistance decreased.When silica was added to carbon black/NR compound， the crosslink degree of the compound decreased，the elongation at break and tear strength of the vulcanizate increased significantly，the compression heat build-up increased slightly，the cut resistance and abrasion resistance were improved，but the rolling resistance increased(thus coupling agent must be used)
