摘　　要：以F-51酚醛树脂添加改性E-51和E-44环氧树脂,考察不同添加比例对两种导电胶的导电性影响规律,并通过体积电阻、热重分析及扫描电镜等方法对其表征。研究结果表明:酚醛添加后,在不降低体积电阻率的前提下有效提高了环氧树脂导电胶的耐热性。By adding F-51 phenolic resin to modify E-51 and E-44 epoxy resin,the effects of different adding proportion on the conductivity of two conductive adhesives were investigated. It was characterized by volume resistance,thermogravimetry and scanning electron morphology. The research results showed that after adding phenolic resin,the heat resistance of epoxy conductive adhesive was effectively improved without reducing the volume resistivity.
