| Abstract: |
| The effects of the addition level of curing agent zinc oxide and stearic acid on the properties of BIIR were investigated.The results showed that，when the addition level of stearic acid was 1 phr，as the addition level of zinc oxide increased，the Mooney viscosity of BIIR compound generally increased，while the curing behavior，crosslink density and physical properties changed little.When the addition level of zinc oxide was 1 phr，as the addition level of stearic acid increased，the Mooney visco-sity of BIIR compound generally decreased，the curing time shortened，the crosslink density of the vulcanizates increased at first and then decreased，and the physical properties tended to decrease. |
