| 中文摘要: |
| 用RPA2000橡胶加工分析仪研究胶料（丁苯橡胶/顺丁橡胶并用胶）硫化过程中填料的聚集程度。结果表明：随着转矩提高，硫化过程中不同配方胶料动态力学性能[储能模量（G′）、损耗模量（G″）和损耗因子（tanδ）]之间的差异增大；随着防焦剂用量增大，促进剂CZ胶料的焦烧时间延长，ΔG′增大，填料聚集程度提高，tanδ随应变增大的增幅增大；迟效型促进剂DZ胶料的焦烧时间较长，硫化速度较慢，在硫化过程中填料聚集时间较长，聚集程度较高，在大应变下tanδ较大；在硫化过程中填料的聚集效应发生在焦烧期和热硫化初期，在保证胶料加工安全性能下，应尽量缩短设计的配方胶料的焦烧时间，提高硫化速度，以降低填料聚集程度。 |
| 英文摘要: |
| The filler aggregation during the vulcanization process of rubber compound （styrene-butadiene rubber/butadiene rubber blend） was studied with RPA2000 rubber processing analyzer.The results showed that the difference between the dynamic mechanical properties[storage modulus（G′），loss modulus（G″） and loss factor（tanδ）] of different formulations compound increased with the increase of the torque.With increase of the amount of scorch retarder，the scorch time of the compound with accelerator CZ was prolonged，ΔG′ increased，the degree of filler network increased，and tanδ increased with the increase of strain.The scorch time of accelerator DZ compound was long and curing rate was low，therefore the time for filler aggregation during curing process was long and the degree of filler aggregation was high，and the tanδ value was high under large strain.It was found that the filler aggregation occurred mostly during the scorch period and initial curing stage.In order to reduce the filler aggregation，the compound formulation was designed to have short scorch time and fast curing speed as long as it possessed good processing safety property. |
