| 中文摘要: |
| 采用单体接枝改性法制备炭黑填充型NBR复合材料，并对其性能进行研究。结果表明，在NBR胶乳与炭黑的混合体系中加入适当的单体M[丙烯酸丁酯（BA）或甲基丙烯酸甲酯（MMA）]和引发剂，可以使单体M与NBR分子链发生接枝反应的同时也与炭黑表面的活性基团发生反应，从而制备NBR/M/炭黑复合材料，采用该方法制备的NBR/M/炭黑复合材料的炭黑分散性良好，物理性能和热稳定性优异。 |
| 英文摘要: |
| A carbon black/NBR composite was prepared by monomer graft modification and its properties were investigated.The results showed that a carbon black/NBR composite was prepared by adding a suitable monomer M [butyl acrylate（BA） or methyl methacrylate（MMA）] and an initiator into the carbon black/NBR latex mixture to make M graft to the molecular chain of NBR and react with the active group on carbon black surface simultaneously；and the obtained composite possessed good black distribution and excellent physical properties and heat stability. |
