Abstract: |
The epoxidized natural rubber(ENR)/nitrile rubber(NBR) blends were prepared using
dicumyl peroxide(DCP) as a curing agent,and their properties were studied. The results showed that the
ENR/NBR blending ratio and the curing agent DCP dosage had little effect on the scorching time and curing
rate of ENR/NBR compound. When the curing agent DCP dosage was 3 phr and the ENR/NBR blending
ratio was 5/95~15/85,the physical properties of ENR/NBR vulcanizate were slightly improved compared
to NBR vulcanizate. When the ENR/NBR blending ratio was 20/80 and the curing agent DCP dosage was
2 phr,the tensile strength and elongation at break of ENR/NBR vulcanizate were the largest. The hysteresis
loss analysis revealed that the ENR/NBR vulcanizate consumed more energy during the stretching process. |
