中文摘要: |
研究丁腈橡胶(NBR)/乙烯乙酸乙烯醋共聚物(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。 |
英文摘要: |
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. |
