| 研究白炭黑用量、硫黄/过氧化物BIBP并用硫化体系的过氧化物BIBP和助交联剂TAIC用量、发泡倍率、预硫化温度和预硫化时间对丁苯橡胶（SBR）发泡材料性能的影响。结果表明：白炭黑用量增大，SBR发泡材料的100%定伸应力、拉伸强度、静刚度和动静刚度比增大，拉断伸长率减小；随着过氧化物BIBP和助交联剂TAIC用量增大，SBR发泡材料的拉伸强度、拉断伸长率、压缩永久变形和动静刚度比减小，100%定伸应力和静刚度增大；随着发泡倍率增大，SBR发泡材料的静刚度减小，动静刚度比增大；预硫化温度为125 ℃和预硫化时间为16 min时，SBR发泡材料的减振性能最佳，此时泡孔直径较小及分布均匀。 |
| 英文摘要: |
| The effects of silica amounts，peroxide BIBP and crosslinking agent TAIC amounts of sulfur/peroxide BIBP blending co-vulcanization system，foaming rates and pre-vulcanization temperatures and time on the properties of butadiene styrene rubber（SBR） foaming materials were investigated.The results showed that，as the silica amounts increased，the tensile stress at 100% elongation，tensile strength，static stiffness and dynamic/static stiffness ratio of SBR foam material increased，while the elongation at break decreased.As the peroxide BIBP and crosslinking coagent TAIC amount increased，the tensile strength，elongation at break，compression set and dynamic/static stiffness ratio of SBR foam material decreased，while the tensile stress at 100% elongation and static stiffness increased.As the foaming ratio increased，the static stiffness of SBR foam material decreased and the dynamic/static stiffness ratio increased.When the pre-vulcanization temperature was 125 ℃ and the pre-vulcanization time was 16 min，the vibration reduction properties of SBR foam material was optimal，the pore diameter was smaller and pore distribution was uniform. |
