摘　　要：研究不同粘合体系对普通硫化体系和低硫高促硫化体系天然橡胶(NR)胶料与汽车衬套骨架粘接性能的影响。结果表明,MEGUM 3270/THIXON 520-PEF,MEGUM 3270/MEGUM 538和THIXON P-6-EF/THIXON OSN-2-EF三种底涂胶粘剂/面涂胶粘剂粘合体系均适合普通硫化体系和低硫高促硫化体系NR胶料与汽车衬套骨架的粘接,其中采用MEGUM 3270/THIXON 520-PEF粘合体系的NR胶料衬套的最大破坏力大于采用其他两种粘合体系的NR胶料衬套。The effects of different adhesive systems on the adhesive properties between natural rubber(NR)compounds with ordinary vulcanization system and low-sulfur high-accelerator vulcanization system and automobile bushing frame were studied.The results showed that all of the three kinds of primer/top coating adhesive bonding systems MEGUM 3270/THIXON 520-PEF,MEGUM 3270/MEGUM 538 and THIXON P-6-EF/THIXON OSN-2-EF were suitable for the bonding between NR compounds with ordinary vulcanization system and low-sulfur high-accelerator vulcanization system and automobile bushing frame,and the maximum destructive force of the bushing of NR compound with MEGUM 3270/THIXON 520-PEF bonding system was greater than those with the other two bonding systems.
