摘要

研究了共混比对三元乙丙橡胶/丁腈橡胶共混物固化和输运特性的影响。研究表明，最大扭矩值随着丁腈橡胶在共混体系中所占比例的增加而增加。随着丁腈橡胶在共混物中掺量的增加，渗透剂输运率降低。实验结果与共混物的形貌相关联;经扫描电镜照片证实。在一定的混合比下，与渗透剂性质有关的平衡吸附顺序为:苯>甲苯>二甲苯。输运机制与菲克趋势有轻微偏差。实验结果与现有的理论模型进行了比较。

Transport of Aromatic Hydrocarbons through EPDM/NBR Blends

The effect of blend ratio on the cure and transport characteristics of EPDM/NBR blends has been investigated. Cure studies showed that the maximum torque values increased with increase of the percentage of NBR in the blend system. As the percentage of NBR in the blends increased, the penetrant transport has been found to be decreased. The experimental observations have been correlated with the morphology of the blends; attested by SEM photographs. The equilibrium sorption with respect to the nature of penetrant has been observed to follow the order: benzene > toluene > xylene for a given blend ratio. A minor deviation from Fickian trend has been observed for the mechanism of transport. The experimental observations have been compared with the existing theoretical models.

期刊介绍： The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
