| 中文摘要: |
| 研究抗硫化返原剂WK-901用量对橡胶隔震支座胶料及成品性能的影响。结果表明：抗硫化返原剂WK-901对胶料的t10和t90基本无影响，但对硫化平坦性有显著影响；抗硫化返原剂WK-901对胶料老化前的物理性能有一定影响，对老化后的物理性能有显著影响；随着抗硫化返原剂WK-901用量的增大，成品橡胶隔震支座内层胶的拉伸强度增大，拉断伸长率降低，支座的屈服后刚度和等效水平刚度均增大。 |
| 英文摘要: |
| The effects of the addition level of anti-reversion agent WK-901 on the properties of the compound and finished product of the rubber isolation bearing were studied.The results showed that anti-reversion agent WK-901 had no effect on t10 and t90，but had a significant effect on vulcanization flatness.The anti-reversion agent WK-901 had certain effect on the physical properties of the compound before aging，and had significant effect on the physical properties of the compound after aging.With increase of the addition level of anti-reversion agent WK-901，the hardness and tensile strength of the inner compound of finished rubber isolation bearing increased，the elongation at break decreased，and both the post-yield stiffness and equivalent horizontal stiffness of the bearing increased. |
