▎ 摘　　要

NOVELTY - Modified epoxy resin comprises component A and component B, where the component A include 50-70 pts. wt. epoxy resin and 15-25 pts. wt. modified silica filler, the modified silica filler is silica nanoparticle modified with silane coupling agent on surface, the component B comprises 8-20 pts. wt. amine curing agents and 1-3 pts. wt. curing catalysts, and the curing catalyst includes porous PDMS nanofiber carrier and triethylphosphine, triethanolamine and modified graphene supported on porous PDMS nanofiber carrier. USE - The modified epoxy resin is useful as electric material, electronic material, matrix and coating for building material, automobile, shipbuilding, aviation, machinery, chemical industry, large water conservancy project and civil construction industry. ADVANTAGE - The resin has improved curing rate, improved heat resistance, improved two-phase interface between epoxy resin and inorganic phase, improved mechanical and chemical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use method of modified epoxy resin, comprising mixing component A and component B, stirring, and then performing heating reaction to obtain modified epoxy resin..
