摘　　要：采用分子蒸馏环氧替代普通液体环氧、双官能度环氧稀释剂替代501稀释剂,制备中型高压电机用硼胺络合物固化的环氧树脂无溶剂浸渍树脂,并与传统配方的浸渍树脂进行了性能对比分析。结果表明:经优化配方后,降低了浸渍树脂的蒸汽压,改善了浸渍树脂固化物的高温介质损耗因数,提高了固化物的热变形温度。A solvent-free epoxy impregnating resin cured by boron-amine complex for medium-sized highvoltage motor was prepared by using molecular distillation epoxy resin to replace common liquid epoxyand using bifunctional epoxy diluent to replace 501 diluent, and its properties were compared with theproperties of traditional impregnating resin. The results show that after optimizing formula, the vapourpressure of the impregnating resin reduces, the dielectric dissipation factor at high temperature of thecured impregnating resin is improved, and the heat distortion temperature increases.
