| 中文摘要: |
| 研究硫黄和发泡剂OBSH-75用量及预硫化工艺对顺丁橡胶/丁苯橡胶并用发泡材料性能的影响。结果表明：添加2份硫黄和3份发泡剂的发泡材料的泡孔直径较小、泡孔均匀且为闭孔结构，动静刚度比较小，物理性能和减震性能较好；预硫化温度为125 ℃、预硫化时间为14 min时，发泡材料的泡孔密度适中，动静刚度比较小，减震性能较好。 |
| 英文摘要: |
| The effects of the amount of sulfur and foaming agent OBSH-75，and the pre-curing process on the properties of butadiene rubber（BR）/styrene-butadiene rubber（SBR） foaming materials were investigated. The results showed that the cell diameter of the foaming materials with 2 phr sulfur and 3 phr foaming agent was smaller，the cell was uniform with closed structure，the dynamic and static stiffness ratio was smaller，and the physical properties and shock absorption property were better. When the pre-curing temperature and pre-curing time were 125 ℃ and 14 min，respectively，the cell density of the foaming materials was moderate，the dynamic and static stiffness ratio was small，and the shock absorption property was good. |
