摘　　要：制备了四种环氧树脂(E-51、AG-80、AFG-90、TDE-85)及其复合树脂体系的液体丁腈橡胶CTBN改性胶黏剂,研究了这些胶黏剂及加入不同质量的TDE-85和AFG-90后的粘接性能。研究结果表明,TDE-85对改性胶的室温剪切和剥离强度贡献较大,AFG-90对高温剪切强度贡献较大。在TDE-85改性胶(TC-23)和TDE-85/E-51复合树脂改性胶(TEC-23)中,添加10%的AFG-90,可使它们的室温、100℃剪切及室温剥离强度分别达到37.4MPa、16.7MPa,65.4N·cm-1和33.7MPa、18.2MPa,60.0N·cm-1,具有较好的综合性能。Four kinds of epoxy resins （E-S1, AG-80, AFG-90, TDE-85） and five kinds of their mixture modified by CTBN were prepared and their adhesion properties were studied. The results showed that the addition of TDE-85 could increase the shear strength and peel strength at room temperature, and the addition of AFG-90 couhl increase the shear strength at 100℃, respectively. By adding 10% of AFG-90, the shear strength at 25℃, 100℃ and peel strength at 25℃ of the CTBN-modified TDE-85（TC-23） and TDE-85/E-51 （TEC-23） could reach 37.4MPa, 16.7MPa, 65.4N ·cm^-1 and 33.7MPa, 18.2MPa, 60.0N·cm^-1 spectively. The adhesive had excellent comprehensive properties.
