Title:
EPOXY RESIN SYSTEM HAVING PHASE SEPARATION STRUCTURE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/119874
Kind Code:
A1
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 1; or, after mixing an epoxy resin and an amine curing agent, pre-polymerization is carried out to obtain a prepolymer 1; after mixing an epoxy resin, an anhydride curing agent and an accelerator, polymerization is carried out to obtain a prepolymer 2; and after the prepolymer 1 and the prepolymer 2 are mixed, curing is carried out to obtain an epoxy resin system having a phase separation structure. The present invention uses an epoxy resin, an anhydride, a polyamine, an accelerator, and so on as raw materials, and 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. Due to the presence of a phase separation structure in a cured resin system, the epoxy resin system has excellent mechanical properties, while also having good shape memory properties.
