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。
採用不同牌號及純度的雙酚F和雙酚A環氧樹脂與甲基六氫苯酐製備成環氧/痠酐浸漬樹脂，對比研究瞭不同環氧樹脂對環氧/痠酐浸漬體繫的粘度、貯存穩定性、固化物力學性能及電性能的影響。結果錶明：在無稀釋劑條件下，由雙酚F配製的浸漬樹脂起始粘度低于雙酚A環氧配製的浸漬樹脂，且環氧樹脂純度越高、有機氯離子含量越少，對浸漬樹脂貯存穩定性和固化反應的影響越小，得到的固化物電性能越好。

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.
