Abstract:
      The effects of BR/NR blend ratio on the properties of the blend were studied，and the blend was used in rubber isolation bearings to investigate its effects on the mechanical properties and temperature dependence of bearings.The results showed that compared with NR compound，BR/NR blend had better processability and low temperature resistance，hot air aging performance was unchanged basically，and the tensile strength and tear strength gradually decreased with the increase of BR/NR blend ratio.Combination of NR and BR was unfavorable to the mechanical properties of rubber bearings and favorable to the temperature dependence.
