中文摘要:
      采用大分子偶联剂改性纳米氮化硅，研究改性纳米氮化硅用量对改性纳米氮化硅/NBR复合材料性能的影响。结果表明，对纳米氮化硅进行改性可以改善其在NBR基体中的分散性；采用少量（0.5~1.5份）改性纳米氮化硅填充NBR可以提高复合材料的物理性能和动态力学性能，并大幅延长相应油封制品的使用寿命。
英文摘要:
      The influence of addition level of nano-Si3N4 modified by macromolecular coupling agent on the properties of modified nano-Si3N4/NBR composites was investigated.The results showed that，after modification， the dispersity of nano-Si3N4 in NBR was improved；the physical properties and dynamic properties of the composite，and the service life of oil seal articles were improved，by adding 0.5~1.5 phr modified nano-Si3N4 in NBR compound.
