| 中文摘要: |
| 研究隐晶质石墨部分替代炭黑N550对乙烯-丙烯酸酯橡胶（AEM）胶料性能的影响。结果表明：隐晶质石墨部分替代炭黑N550，可以大大缩短AEM胶料的硫化时间，在保持耐油性能和耐热老化性能的前提下，降低生热和原材料成本；45 μm粒径的隐晶质石墨替代炭黑N550的比例不宜超过40%；对于拉伸强度要求高的AEM胶料，适合采用5 μm粒径的隐晶质石墨部分替代炭黑N550，替代比例不宜超过30%。 |
| 英文摘要: |
| Cryptocrystalline graphite was used in the ethylene-acrylate rubber（AEM） compound to replace part of the carbon black N550 and its effect on the properties of the compound was investigated in this study. The results showed that the vulcanization time of AEM compound with part of the carbon black replaced by cryptocrystalline graphite was significantly shortened，the oil resistance and heat aging resistance were maintained，the heat build-up and the cost of raw materials were reduced. The replacement of carbon black N550 by cryptocrystalline graphite with an average particle size of 45 μm was inadvisable to exceed 40%. In the compound for high tensile strength performance，cryptocrystalline graphite with an average particle size of 5 μm was more suitable to replace part of the carbon black N550，but the ratio should not exceed 30%. |
