| 中文摘要: |
| 研究促进剂TBzTD对白炭黑补强天然橡胶（NR）/溶聚丁苯橡胶（SSBR）并用胶性能的影响。结果表明：在白炭黑补强NR/SSBR并用体系中，随着促进剂TBzTD用量的增大，胶料的门尼焦烧时间缩短，硫化速率增大，硫化胶的300%定伸应力和拉伸强度增大，拉断伸长率减小，撕裂强度先增大后减小，耐磨性能和抗湿滑性能提高，滚动阻力降低；促进剂TBzTD用量为0.5份时，胶料的耐老化性能最佳。 |
| 英文摘要: |
| The effect of accelerator TBzTD on the properties of natural rubber（NR）/solution polymerized styrene butadiene rubber（SSBR） blend reinforced with silica was studied.The results showed that in the NR/SSBR blend system reinforced with silica，with the increase of the dosage of accelerator TBzTD，the Mooney scorch time of the compound was shortened，the curing rate was increased，the modulus at 300% elongation and tensile strength of the vulcanizate were increased，the elongation at break was decreased，and the tear strength increased at first and then decreased，and wear resistance and wet skid resistance was improved，the rolling resistance was reduced.When the dosage of accelerator TBzTD was 0.5 phr，the aging resistance of the compound was the best. |
