以环氧树脂作为载体树脂,聚酰胺为固化剂,石墨、镍粉、银包铜粉为导电相,铁铬合金粉体为磁性组分,制备多组分环保磁性导电浆料,并研究了浆料的导电、介电和磁性能。研究结果表明:最终获得浆料的体积电阻值最小为7.60×10-2Ω·m;比饱和磁化强度、剩余磁化强度、矫顽力、磁导率分别为156.95 emu/g、117.57 emu/g、136.05 Oe和700。
Abstract：Using epoxy resin as carrier resin,polyamide as curing agent,graphite,nickel powder,silvercoated copper powder as conductive phase,and ferrochromium alloy powder as magnetic component,the multicomponent environmentally-friendly magnetic conductive slurry was prepared. The conductive,dielectric and magnetic properties of the slurry were also studied. The research results showed that the minimum volume resistance of the final slurry was 7.60×10-2Ω·m. The specific saturation magnetization,residual magnetization,coercive force and permeability were 156.95 emu/g,117.57 emu/g,136.05 Oe and 700,respectively.
