Abstract
The present invention relates to an epoxy resin system having a phase separation structure, a preparation method therefor and an application thereof. After mixing an epoxy resin, an amine curing agent and an epoxy diluent, pre-polymerization is carried out to obtain a prepolymer; or, after mixing an epoxy resin and an amine curing agent, pre-polymerization is carried out to obtain a prepolymer; after mixing an epoxy resin, an anhydride curing agent and an accelerator, polymerization is carried out to obtain a prepolymer; and after the prepolymerand the prepolymerare mixed, curing is carried out to obtain an epoxy resin system having a phase separation structure. The present invention controls the formation of a thermosetting epoxy resin system having a phase separation structure by means of preparing different epoxy resin pre-polymerization systems and using an interface reaction between the different pre-polymerization systems.
