中文摘要: |
研究了预处理短纤维用量对乙炔炭黑填充甲基乙烯基硅橡胶(VMQ)/EPDM共混硫化胶拉伸、撕裂、耐屈挠疲劳和导电性能的影响。实验结果表明,加入适量短纤维对VMQ/EPDM体系有一定的补强作用;纤维用量较大时,导电性能下降。加入4.0份左右的预处理短纤维,可使VMQ/EPDM共混导电橡胶获得良好的物理机械性能和导电性能。 |
英文摘要: |
The influence of the level of the pretreated short-fibre on tensile strength,tear strength,flex fatigue and conductivity of the acetylene black-filled VMQ/EPDM blend vulcanizate was studied. The test results showed that the adequate level of pretreated short-fibre provided a certain reinforcement to VMQ/EPDM blend;the greater level of pretreated short-fibre resulted in the decrease of the conductivity. The addition of 4.0 phr pretreated short-fibre provided good physical properties and conductivity to VMQ/EPDM blend. |
