| Abstract: |
| Soybean oil was evaluated as plasticizer of NBR，and the effect of addition level of soybean oil on the Mooney viscosity，rheological behavior and physical properties of NBR compound were investigated and compared with plasticizer 261.The results showed that，compared with plasticizer 261 filled NBR compound，soybean oil filled NBR compound had a lower Mooney viscosity，lower apparent viscosity，and better processability，indicating that the plasticizing effect of soybean oil was better.When the addition level of plasticizer was 5 phr，the tensile strength and elongation at break of soybean oil filled NBR compound were higher than those of plasticizer 261 filled NBR.However，when the addition level of plasticizer further increased，the physical properties of soybean oil filled NBR compound became worse. |
