摘　　要：研究芳纶浆粕对炭黑N990/氟醚橡胶复合材料的物理性能、微观结构和耐低温性能的影响,为高性能氟醚橡胶复合材料的开发提供参考。结果表明:添加1份未经热处理芳纶浆粕和热处理芳纶浆粕的氟醚橡胶复合材料的硫化特性和动态力学性能无明显变化,100%定伸应力、300%定伸应力、拉伸强度和撕裂强度提高;热处理芳纶浆粕在橡胶基体中的分散性和与橡胶基体的界面粘接性较好,对氟醚橡胶复合材料的补强效果更为显著;添加1份未经热处理芳纶浆粕和热处理芳纶浆粕对氟醚橡胶复合材料的耐低温性能影响较小,可在保持氟醚橡胶复合材料良好的耐低温性能的基础上提高其物理性能。The effect of aramid pulp on physical properties,microstructures and low temperature resistance of carbon black N990/fluoroether rubber composites was studied to provide reference for the development of high performance fluoroether rubber composites.The results showed that there was no significant change in the vulcanization characteristics and dynamic mechanical properties of the fluoroether rubber composites with addition of 1 phr non-heat-treated aramid pulp and heat-treated aramid pulp.The modulus at 100%elongation,modulus at 300%elongation,tensile strength and tear strength were increased.The dispersion of heat-treated aramid pulp in the rubber matrix and the interfacial adhesion with the rubber matrix were better,and the reinforcement effect of fluoroether rubber composites was more significant.Addition of 1 phr non-heat-treated aramid pulp and heat-treated aramid pulp had little effect on low temperature resistance of fluoroether rubber composites,and could improve their physical properties of fluoroether rubber composites while maintaining the good low temperature resistance.
