| 摘 要： | 研究了助交联剂液体乙烯基聚丁二烯对氢化丁腈橡胶(HNBR)硫化过程和物理机械性能的影响，结果表明：当其用量为4份时，弹性扭矩最大，拉伸强度24．8MPa，拉断伸长率334％，分别比空白样提高13％和50％；表观交联密度适宜，压缩永久变形29％低于空白样的44％，6份时的47％和8份时的55％；热空气老化后仍保持较高的强伸性能。

| Abstract: | The effect of liquid vinyl polybutadiene as coagent on curing course and physical properties of HNBR was investigated.The results showed that when liquid vinyl polybutadiene was 4 phr,the elastomeric torque was highest,the tensile strength was 24.8 MPa and the elongation at break was 334%,which increased by 13% and 50% than those of the control compound,respectively;the apparent crosslink density was proper,the compression set was 29%,which was lower 44% than that of the blank compound,and it was lower 47% and 55%,respectively,as liquid vinyl polybutadiene 6 phr and 8 phr.The tensile properties remained high after thermal aging. |
