摘　　要：研究丁腈橡胶(NBR)/乙烯-乙酸乙烯酯共聚物(EVM)并用比对并用胶物理性能、耐老化性能、耐油性能和耐热性能的影响。结果表明:随着EVM用量的增大,NBR/EVM并用胶的100%定伸应力、拉伸强度、撕裂强度和压缩永久变形增大,脆性温度和拉断伸长率变化很小,耐老化和耐热性能改善,耐油性能小幅下降。NBR与EVM具有良好的相容性。The effect of blending ratio of NBR/EVM on the physical properties,aging property,oil resistance and heat resistance of NBR/EVM blends was investigated. The results showed that, as the addition level of EVM increased, the modulus at 100% elongation, tensile strength, tear strength and compression set of NBR/EVM blends increased, the brittleness temperature and elongation at break changed a little,the aging property and heat resistance were improved,and the oil resistance decreased slightly. The compatibility of NBR and EVM was good.
