| Abstract: |
| The effect of the feeding methods of vulcanization system on the properties of natural rubber（NR）/butadiene rubber（BR） blends was studied.The results showed that the tear strength of NR/BR blends was greatly affected by the feeding mode of the vulcanization system，while the tolerance of Shore A hardness，tensile strength and elongation at break was relatively high.When zinc oxide，stearic acid and sulfur were all added into BR phase，NR/BR blends had good wear resistance，low dynamic loss under large strain，showing good comprehensive performance. |
