▎ 摘　　要

NOVELTY - Multifunctional modified epoxy resin adhesive comprises 100 pts. wt. epoxy resin, 1-4 pts. wt. phosphaphenanthryl cyanuric chloride modified graphene oxide, 20-40 pts. wt. triethylenetetramine, and 2-10 pts. wt. triethanolamine. USE - Used as multifunctional modified epoxy resin adhesive. ADVANTAGE - The method: improves the interface compatibility between graphene oxide and epoxy resin by covalently grafting phosphaphenanthryl and cyanuric chloride organic functional groups on the surface of graphene oxide; avoids the agglomeration of graphene oxide in the epoxy resin matrix, which is conducive to the stable dispersion of graphene oxide; and covalently bonds organic functional groups e.g. cyanuric chloride and phosphaphenanthryl on the surface of graphene oxide, which further increases the application range of graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the multifunctional modified epoxy resin adhesive, comprising stirring epoxy resin, phosphaphenanthryl cyanuric chloride modified graphene oxide, triethylenetetramine and triethanolamine, uniformly mixing, and then ultrasonically treating for 4-10 hours to obtain multifunctional modified epoxy resin adhesive.
