摘　　要：研究了不同用量的两种填料(炭黑、白炭黑)对EVM-GMA/XNBR并用胶的加工性能、力学性能、Payne效应、DIN磨耗的影响,并进行了微观结构的分析。结果表明,炭黑和白炭黑作为EVM-GMA/XNBR并用胶的补强填料能够缩短工艺正硫化时间,提高硫化效率;同时使复合材料的机械性能和耐磨性能提高。当炭黑做补强填料时,复合材料的压缩永久变形较小,炭黑的用量为40份时,复合材料的综合性能最好。The effect of different amounts of two kinds fillers(carbon black and silica)on the processing performance,mechanical properties,Payne effect,DIN abrasion and microstructure of EVM-GMA/XNBR blends were studied.The results showed that carbon black and silica as the reinforcing filler of the EVM-GMA/XNBR blends could shorten optimum curing time,improve the vulcanization efficiency,and improve the mechanical properties and wear resistance of the composite.When carbon black was used as reinforcing and the dosage was 40 phr,the compression set was better,and the comprehensive performance was the best.
