| 中文摘要: |
| 研究裂解炭黑（CBp）/炭黑N330并用对天然橡胶（NR）胶料性能的影响。结果表明：随着CBp用量的增大，NR胶料的Fmax－FL减小，即交联密度减小，但CBp可以促进NR胶料的硫化；与CBp相比，在NR基体中炭黑N330的粒径较小且分布均一，分散性较好；随着CBp用量的增大，NR硫化胶的交联密度减小，邵尔A型硬度、定伸应力和拉伸强度减小，耐磨性能变差。 |
| 英文摘要: |
| The effects of pyrolysis carbon black（CBp）/carbon black N330 blend on the properties of natural rubber（NR） compounds were studied.The results showed that with the increase of the addition level of CBp，the Fmax－FL of the compound decreased，which meaned the cross-linking degree decreased，but CBp could promote the vulcanization of NR compound.Compared with CBp，carbon black N330 had a smaller particle size and uniform distribution in NR matrix，with better dispersion.As the addition level of carbon black N330 increased，the cross-linking density of NR vulcanizate decreased，the Shore A hardness，tensile stress at a given elogation and tensile strength decreased，and the wear resistance deteriorated. |
