【摘要】 <正>在最近的研究中,我们首次在丁腈橡胶／聚氯乙烯(NBR／PVC)合金中添加无水硫酸铜 (CuSO4)粉末,在没有任何交联剂的存在下,混合物可通过NBR中所含的腈基(-CN)同CuSO4 粒子之间的配位作用实现交联,这是有别于传统的新颖交联方法。研究中我们还发现,硫酸铜粒子除了作为交联剂,还起到了无机增强填料的作用,使得最终的材料具有非常优异的力学性能。因此,考察(NBR／PVC)／CuSO4混合物的配位交联行为对于探究材料的交联机理,选更多还原

【Abstract】 The crosslinking behaviors of NBR/PVC alloy filled with anhydrous copper sulfate (CuSO4) compounds were investigated by DMA. Under calefactive testing, the curve of (NBR/PVC)/CuSO4 compound showed two transitions, suggesting that the crosslinking mechanism is complicated. From isothermal testing results, E’ of all the samples, except that of NBR/PVC alloy, increased obviously due to the crosslinking induced by the coordination between -CN and CuSO4.更多还原
