摘　　要：采用不同牌号及纯度的双酚F和双酚A环氧树脂与甲基六氢苯酐制备成环氧/酸酐浸渍树脂,对比研究了不同环氧树脂对环氧/酸酐浸渍体系的粘度、贮存稳定性、固化物力学性能及电性能的影响。结果表明:在无稀释剂条件下,由双酚F配制的浸渍树脂起始粘度低于双酚A环氧配制的浸渍树脂,且环氧树脂纯度越高、有机氯离子含量越少,对浸渍树脂贮存稳定性和固化反应的影响越小,得到的固化物电性能越好。An epoxy/anhydride impregnating resin was prepared using different types and purity of bisphe-nol F and bisphenol A epoxy resin and methyl hexahydrophthalic anhydride, and the effects of different epoxy on the viscosity and storage stability of the epoxy/anhydride impregnating resin, mechanical proper-ties and dielectric properties of the cured resin were studied. The results show that the viscosity of the impregnating resin prepared by bisphenol F epoxy resin is lower than that of the impregnating resin pre-pared by bisphenol A epoxy resin without diluent. The more the purity of epoxy resin and the less the content of organic chlorine, the less the influence on the storage stability and curing reaction of the im-pregnating resin, and the better the electrical properties of the cured resin is.
