摘要: 采用液體丁氰橡膠及納米SiO2對環氧樹脂進行改性,借助于掃描電鏡(SEM)和力學性能測試手段研究了液體丁氰橡膠及納米SiO2在環氧樹脂體系中的形貌及增韌機理.結果表明,液體丁氰橡膠及納米SiO2對環氧樹脂都具備良好的增韌效果.Abstract: Epoxy resin was modified by liquid butadiene-arylonitrile rubber and nano-SiO2 powder. The morphology of the modified epoxy resin and the toughening mechanism of liquid butadiene-arylonitrile rubber and nano-SiO2 powder were studied by SEM and impact toughness tests. The results show that epoxy resin can be effectively toughened by liquid BN rubber and nano-SiO2 powder.
