摘　　要：针对环氧树脂耐湿热性差和脆性大的缺点,采用热固性聚酰亚胺BMI和DDS改性双酚A型环氧树脂E-51,以DDM为固化剂,加入促进剂CA-30,制得一种双组分的高强度双马来酰亚胺改性环氧胶粘剂(ABE胶粘剂),并对ABE胶粘剂进行了热性能、力学性能和介电性能的研究。结果表明,优化的双马来酰亚胺改性环氧胶粘剂拉伸剪切强度达到22.4 MPa,吸水性为0.47%,并且具有较长的贮存时间和良好的介电性能。The two-component modified epoxy adhesive（ABE adhesive） consisting of the biphenyl A type E-51 epoxy resin, which was modified with 4,4＇-bismaleimide diphenyl methane（BMI） and diamino diphenyl sulphone（DDS）, diamino diphenyl methane（DDM） as the curing agent and CA-30 promoter was prepared to improve the hydrothermal performance and toughness of the epoxy adhesives. The thermal, mechanical and dielectric properties of the ABE adhesive were investigated. The results showed that the optimized MBI-modified epoxy adhesive had the tensile shearing strength of 22.4 MPa, water absorption of 0.47% and good dielectric performance and storage stability.
