摘　　要：以环保大豆油用作丁腈橡胶(NBR)增塑剂,研究其用量对NBR胶料门尼粘度、流变性能和物理性能的影响,并与增塑剂261进行对比。结果表明:与增塑剂261增塑NBR胶料相比,大豆油增塑NBR胶料的门尼粘度和表观粘度较小,增塑效果和加工性能较好;当增塑剂用量为5份时,大豆油增塑NBR硫化胶的拉伸强度和拉断伸长率较大;但随着增塑剂用量的增大,大豆油增塑NBR硫化胶的物理性能变差。Soybean oil was evaluated as plasticizer of NBR, and the effect of addition level of soy- bean 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 soy- bean 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 com- pound became worse.
