摘　　要：以环氧大豆油(ESO)为环氧树脂(EP)的增塑剂、环氧氯丙烷(ECH)和丙烯腈(AN)改性己二胺为固化剂,制得ESO改性EP胶粘剂。探讨了增塑剂种类和含量对EP胶粘剂性能的影响。结果表明:当n(己二胺):n(ECH):n(AN)=1:0.3:1.5、w(ESO)=20%时,相应EP胶粘剂的剪切强度、断裂伸长率和外推起始温度分别比纯EP体系增加了10%、400%和20%;ESO是一种高增韧性、高耐热性的环保型增塑剂,相应EP胶粘剂的透明性、柔韧性和耐高(低)温性俱佳。With epoxidized soybean oil （ESO） as plasticizer of epoxy resin （EP）, hexamethylene diamine modified by epichlorohydrin（ECH） and acrylonitrile（AN） as curing agent,an EP adhesive modified by ESO was made. The influences of types and contents of plasticizers were discussed on properties of EP adhesives. The results showed that the shear strength, elongation at break and extrapolated initial temperature of corresponding EP adhesive were 10% ,400% and 20% respectively more than those of pure EP system when molar ratio of n （hexamethylene diamine）：n（ECH）：n（AN） was 1：0.3：1.5, and mass fraction of ESO was 20%. The ESO was a high toughening,high heat-resistance and environment-friendly plasticizer, the corresponding EP adhesive had good transparency ,flexible and high （low） temperature- resistance.
