| 中文摘要: |
| 采用硬脂酸对绢云母进行表面改性，研究改性绢云母用量对绢云母/顺丁橡胶复合材料性能的影响。结果表明，随着改性绢云母用量的增大，复合材料的硫化速度加快，转矩和门尼粘度增大，加工性能下降；邵尔A型硬度、热导率和介电常数逐渐增大，拉伸强度、拉断伸长率、拉断永久变形、撕裂强度、表面电阻率和体积电阻率均先增大后减小，而击穿电压变化不大。 |
| 英文摘要: |
| The surface of sericite was modified by stearic acid，and the effect of addition level of modified sericite on the properties of sericite/BR composite was investigated.The results showed that，as the addition level of modified sericite increased，the curing rate of composite increased，the torque and Mooney viscosity increased，so the processibility decreased.The Shore A hardness，heat conduction coefficient and dielectric constant increased，the tensile strength，elongation at break，tensile set at break，tear strength，surface resistivity and volume resistivity increased at first and then decreased，but the breakdown voltage changed little. |
