中文摘要: |
研究聚醚型混炼型聚氨酯(MPU)/丁腈橡胶(NBR)并用比对MPU/NBR并用胶性能的影响。结果表明:随着NBR用量的增大,胶料的MH增大,t90延长,硫化速率下降;硫化胶的交联密度增大,压缩永久变形减小,热稳定性和耐低温性能提高,耐臭氧老化性能下降,耐油性能变化不大。 |
英文摘要: |
The effect of the blending ratio of millable polyether polyurethane(MPU)and NBR on the properties of MPU/NBR blend was investigated.The results showed that,as the addition level of NBR increased,the MH of the compound increased,t90 was extended,and curing rate decreased.With more NBR,the crosslinking density of the vulcanizate increased,permanent compression set decreased,thermal stability and low temperature resistance were improved,ozone aging resistance decreased,and oil resistance changed little. |
