| Abstract: |
| By blending NBR/hindered phenol AO-60 hybrid materials（abbreviated as NBR/AO-60）with NR，the NR/NBR/AO-60 composites were prepared. The microstructure，damping property and physical properties of the composites were investigated by transmission electron microscopy，differential scanning calorimetry，dynamic mechanical analyzer and rubber processing analyzer. The results showed that，the compatibility of NR with NBR/AO-60 was good，and when the blending ratio of NR/NBR/AO-60 was 50/50/20，the composites exhibited a co-continuous morphology. With the weight of NBR/AO-60 increasing，the loss factor of the composites increased significantly within the temperature range of －20～＋40 ℃ and the strain range of 0～150%，which showed the high damping property to meet the application requirements of seismic isolation bearing. This NR/NBR/AO-60 composites（blending ratio was 50/50/20）which possessed high damping，high strength and high flexibility had good application prospects in the field of rubber seismic isolation bearing. |
