| Abstract: |
| The reclaimed butadiene rubber （RBR）/polyolefin （POE） thermoplastic vulcanizate（TPV） was prepared by dynamic vulcanization technology，and the curing characteristics of sulfur curing system and the effect of silica on the physical properties and dynamic mechanical properties of RBR/POE TPV were investigated. The results showed that RBR/POE TPV could be further vulcanized with the sulfur curing system. The modulus at 300% elongation and tensile strength of RBR/POE TPV increased as the addition level of silica increased，while the elongation at break and tensile permanent set decreased. Moreover，the modulus at 300% elongation， tensile strength and storage modulus of RBR/POE TPV filled with Si69 modified silica were higher compared with those of RBR/POE TPV filled unmodified silica，respectively，while the elongation at break and tensile permanent setwere lower. |
