摘要: 用液体端俊基丁睛橡胶(CTBN)改性的环氧树脂体系的胶接性能明显CTBN中丙烯睛(AN)含量的影响。本文研究了以改性二氢二胺体系为固化剂，在中温(120℃ )固化条件下，不同丙烯睛含量的CTBN对增韧环氧树脂体系胶接性能的影响。通过在光学显微镜下对体系升温至固化过程的相变化观察和扫描电镜下对胶接破坏断口的观察，探讨了造成这种影响的原因。Abstract: The effect of acrylonitrile (AN)content in liquid carboxyl terminated butadine-acrylonitrile rubber (CTBN) on the bonding properties of CTBN modified epoxy adhesive was apparent, This paper presented an investigation about such effect in the case of intermediate temperature(120℃ )curing adhesive with modified dicyandiamide system as curing agent, By means of light microscopic observation of heat curing process and scaning eletron microscopic observationof lap shear fracture surface of CTBN modified epoxy system, the reason that results in such effect was examined.
