摘　　要：以改性和未改性纳米白炭黑为增强填料制备了乙烯-醋酸乙烯酯(EVA)/线型低密度聚乙烯(LLDPE)/纳米白炭黑复合材料;探讨了纳米白炭黑和EVA接枝马来酸酐(EVA-g-MAH)的用量对复合材料的力学、热学、加工流动性能的影响。结果表明,经γ-缩水甘油醚氧丙基三甲氧基硅烷(KH560)改性的纳米白炭黑用量为10份时,对EVA/LLDPE复合体系的增强效果最好,且添加8.0份的EVA-g-MAH对复合体系有较好的增容效果;一定用量的改性纳米白炭黑能改善EVA/LLDPE复合体系的热稳定性和耐热氧老化性,但却降低了体系的加工流动性。The modified and unmodified nano-silica were as a reinforced filler to prepare ethylene-vinyl acetate （EVA）/LLDPE/nano-silica composites, it discussed the effect of nano-silica and EVA-g-MAH amount on the composite mechanical, thermal, process flow performance. The results showed that： when the γ-glycidoxypropyl trimethoxysilane （KH560） modified nano silica amount of 10 phr, EVA/LLDPE composites had the best enhancements, and adding 8.0 phr of the EVA-g-MAH on the composite system had better compatibilization effect ; a certain amount of modified nano silica can improve EVA/LLDPE composites thermal stability and thermal oxidative aging, but reduce the system＇s processing fluidity.
