| 中文摘要: |
| 试验研究硅烷偶联剂Si69，Si75和KH560对白炭黑填充溴化丁基橡胶（BIIR）/天然橡胶（NR）并用胶性能的影响。结果表明：随着硅烷偶联剂Si75或KH560用量的增大，胶料的挤出膨胀率呈增大趋势，门尼粘度和Fmax减小，Payne效应减弱，定伸应力和拉伸强度呈增大趋势，拉断伸长率和撕裂强度呈减小趋势，加工性能和老化后耐屈挠性能改善；硅烷偶联剂Si75和KH560能够明显改善白炭黑填充BIIR/NR并用胶的加工性能和老化后的耐屈挠性能。 |
| 英文摘要: |
| The effects of silane coupling agents Si69，Si75 and KH560 on the properties of brominated butyl rubber（BIIR）/natural rubber（NR） blend filled with silica were studied. The results showed that with the increase of the amount of silane coupling agent Si75 or KH560，the extrusion expansion rate of the compound increased，the Mooney viscosity，Fmax and the Payne effect decreased，the modulus and tensile strength increased，the elongation at break and tear strength decreased，and the processability and flex resistance after aging were improved.Silane coupling agents Si75 and KH560 could significantly improve the processability and flex resistance after aging of BIIR/NR blend filled with silica. |
