NOVELTY - Functionalized graphene oxide modified nonionic aqueous epoxy emulsifier compounds (I) are new. USE - (I) are useful in aqueous epoxy anticorrosive paint (claimed). ADVANTAGE - (I): have improved dispersibility. DETAILED DESCRIPTION - Functionalized graphene oxide modified nonionic aqueous epoxy emulsifier compounds of formula (I) are new. G = WEPN, 2-hydroxy-3-(2-(3-(2-(2-hydroxybutoxy)benzyl)-2-(oxiran-2-ylmethoxy)benzyl)phenoxy)propyl 2-(1-methoxypropan-2-yloxy)ethyl malonate moiety of formula (II); m and n = 5-50; q = 2-4; R1 = -C6H4-, -CH=CH- or -CH2CH2-; R2 = H or CH3; and R3 = CH3CH2CH2CH2- or -CH3. INDEPENDENT CLAIMS are also included for: (1) preparation of (I); and (2) use of (I) in aqueous epoxy anticorrosive paint comprising adding functionalized graphene oxide modified nonionic aqueous epoxy emulsifier and bisphenol A epoxy resin or F type phenolic epoxy resin into reaction vessel in a molar ratio of 1:8-25, uniformly mixing, then adding water and performing reverse conversion to obtain epoxy resin aqueous emulsion having a solid content of 40-60%, where aqueous epoxy anticorrosive paint is obtained by adding room temperature curing nonionic aqueous epoxy curing agent into epoxy resin aqueous emulsion to obtain film.
