| 中文摘要: |
| 研究增粘树脂对减震衬套（铁骨架）用天然橡胶（NR）胶料粘接性能的影响。结果表明：选用ME3270/ME538粘合体系，对2～6 mm胶层厚度的粘接试样（粘接基材为铁片）进行剥离试验，铁片剥离面残留很厚的胶层；添加2～4份BN-1增粘树脂的减震衬套胶料的硫化特性和物理性能无明显变化；采用ME3270/ME538粘合体系、选择BN-1增粘树脂用量为2份的NR胶料、采用大的注胶压力（21 MPa）制备的减震衬套的粘接性能和台架试验结果满足要求。 |

| The effect of tackifying resin on the adhesive properties of natural rubber（NR） compounds for the shock absorber bushings（iron skeleton） was studied.The results showed that using the ME3270/ME538 adhesive system，peeling tests were conducted on adhesive samples（with iron sheet as adhesive substrate） with a thickness of 2～6 mm，and a thick compound layer remained on the peeled surface of the iron sheet.Adding 2～4 phr of BN-1 tackifying resin did not result in significant changes in the curing characteristics and physical properties of the shock absorbing bushing compound.The bench test results and adhesive property of the shock absorbing bushing product prepared with the ME3270/ME538 bonding system，the NR compound with 2 phr of BN-1 tackifying resin and a high injection pressure（21 MPa） met the requirements. |
