| 研究了用炭黑N293，N330和N550作导电填料的NR，NBR 和EPDM导电橡胶的压敏性和热敏性。结果得出，用高结构、小粒径的炭黑N293作导电填料的NR，NBR和EPDM导电橡胶，压敏性和热敏性均差；用中等结构、较大粒径的炭黑N550作导电填料的NR和EPDM导电橡胶，压敏性较好，热敏性较差；用中等结构、中等粒径的炭黑N330作导电填料的NBR导电橡胶压敏性较好，在一定压力范围内热敏性也较好。 |
| 英文摘要: |
| The pressure-sensitivity and thermo-sensitivity of NR，NBR and EPDM were investigated by using N293，N330 and N550 carbon blacks as the conductive fillers.The results showed that both the poor pressure-sensitivity and the poor thermo-sensitivity for NR，NBR and EPDM conductive rubbers were obtained by using N293 with high structure and small particle size as the conductive filler；the better pressure-sensitivity and the poor thermo-sensitivity for NR and EPDM conductive rubbers were obtained by using N550 with medium structure and greater particle size；the better pressuresensitivity and the better thermo-sensitivity under certain pressure for NBR conductive rubber were obtained by using N330 with medium structure and medium particle size. |
