【摘要】 本文研究了环氧树指为主剂粘料，咪唑类改性物为固化剂，石墨和银粉为导电填料的导电粘合剂。着重研究了组成配方对粘合剂的导电性能和胶粘性能的影响，同时探讨了粘合剂的固化行为。结果表明，当环氧树脂：银粉：石墨＝１００：２００：３３（ｗｔ），改性咪唑为１５份（对１００份环氧树脂而言，以下同），丁腈橡胶为１份时，粘合剂的体积电阻率为４．７×１０－４Ω·ｃｍ剪切强度为５．３ＭＰａ，中温快速固化。更多还原

【Abstract】 Electric conductive adhesives were prepared using epoxy resin asthe a(jherent, modified imidazole as the curing agent, and graphite and / or silver powder as tile conductive filler. The effeCt of composition of the adhesiveon the conductivity and adhesivity and the effect of its curing process on theconductivity were investigated. The bulk resistivity and shear strength of theadhesive are 4.7 x 10 -4 Ω. cm and 5.3 MPa respectively when the compositionis epoxy resin t silver powder graphite= 100 : 200 : 33 (in weight), modifiedimidazole 15phr, and NBR 1 phr. This adhesive can be cured rapidly at moderate temperature.更多还原
