The present invention discloses an organofluorine modified epoxy resin for increasing the surface flashover voltage, and preparation methods and applications thereof. In the present invention, the organofluorine modified epoxy resin is prepared from bisphenol A epoxy resin and hexafluorobisphenol A as raw materials in a mild environment in the presence of tri-(dimethylaminomethyl)phenol as a catalyst. Due to the reasonable proportion of the raw materials, the performance of the resin is optimized, the process is simple, and it is easy to realize industrial production. By using the modified resin as a matrix and adding a curing agent, a filler and an accelerant, a modified resin composite is prepared. In the present invention, a CF.sub.3 group is introduced in the epoxy resin without changing the surface state of the epoxy composite insulating material, the volume/surface resistivity of the material is reduced, it is less likely to accumulate charges on the material surface.

Provided is an epoxy resin composition that has excellent electric characteristics (particularly low dielectric tangent), and that can achieve high adhesive strength to metal. Specifically, provided is an epoxy resin composition comprising an active ester compound and an epoxy resin having a specific structure.
