摘　　要：以顺丁橡胶(BR)为基体,石榴石微波铁氧体(YIG)为改性组分,制备了YIG/BR复合弹性体。实验对复合弹性体的结构和微观面貌进行了表征,并分别对YIG含量和BR含量对复合弹性体的性能影响进行了探讨。结果表明,YIG含量对力学性能、硫化性能和阻尼性能的影响作用显著,当其含量增大时,复合弹性体的拉伸强度和邵尔硬度上升,断裂伸长率先上升后下降,最低硫化转矩和最高硫化转矩上升,焦烧时间和硫化时间减小,拉伸恢复力和压缩恢复力上升。而BR含量对阻尼系数影响显著,复合弹性体的最大阻尼系数与BR含量呈正相关联系。Polybutadiene based composite elastomer was prepared by using polybutadiene as matrix and garnet microwave ferrite as modified component.The structure and microscopic appearance of the composite elastomer were characterized,and the effects of the content of YIG garnet microwave ferrite and polybutadiene rubber on the properties of the composite elastomer were investigated.The results show that the content of YIG garnet microwave ferrite has a significant impact on mechanical properties,vulcanization properties,and damping properties.As its content increases,the tensile strength and shore hardness of the composite elastomer increase,the fracture elongation first increases and then decreases,the minimum and maximum vulcanization torque increase,the scorch time and vulcanization time decrease,and the tensile and compressive recovery force increase.The content of polybutadiene has a significant impact on the damping coefficient,and the maximum damping coefficient of the composite elastomer is positively correlated with the content of polybutadiene.
