Abstract:
      The effect of trans polybutadiene-isoprene rubber（TBIR） on the properties of natural rubber （NR）/styrene butadiene rubber（SBR） blend was studied. The results showed that the compatibility of NR and SBR of NR/SBR/TBIR blend was improved when 15 phr TBIR was used to replace NR，while the tensile strength and tensile stress at a given elongation were slightly reduced，and the wear resistance，compression fatigue resistance and flexural fatigue resistance were improved. When 15 phr TBIR was used to replace SBR，the compatibility of NR and SBR of NR/SBR/TBIR blend was significantly improved，the tensile properties had a little change，and the wear resistance，compression fatigue resistance and flexural fatigue resistance were improved. When 15 phr TBIR was used to replace NR/SBR blend，most of the properties of the NR/SBR/TBIR blend were between the properties of the blends in which TBIR was used to replace either NR or SBR，the wet skid resistance was improved，and rolling resistance was reduced. When 6 phr TBIR was directly added to the NR/SBR blend，the compatibility between NR and SBR of NR/SBR/TBIR blend was also improved，the wear resistance，compression fatigue resistance and flexure fatigue resistance were improved，and the wet skid resistance and rolling resistance were reduced.
