摘　　要：以双酚F环氧树脂和导电银粉为基本原料,制备了导电油墨。分析了银粉、溶剂、固化剂与导电油墨电阻率之间的关系。结果表明,银粉填充量达到75%(质量分数),含醚结构醋酸酯和松油醇混合溶剂占环氧树脂树脂质量分数达到55%,咪唑盐13%(相对树脂的质量分数)时,导电油墨的电阻率达到最低,其值为9×10^(-4)Ω·cm。Conductive ink was prepared by using Bisphenol F epoxy resin and the electrically conductive silver powder as the basic raw material. We discussed the effects of different factors such as silver, diluents, curing agent and the resistivity were on the conductivity for conductive ink. The results showed that the resistivity of conductive ink reached 9×10^-4Ω·cm when the silver filling mass fraction reaches 75%, the weight ratio of mixed solvent with containing ether acetate and terpineol reaches 55% in the mixed solvent of epoxy resin, and the mass fraction of the imidazole salt （relative to the resin） arrives 13%.
