An ionic aqueous epoxy curing agent, a preparation method therefor and the use thereof. The aqueous epoxy curing agent is prepared by reacting the following raw materials in parts by weight: a) 1 part of a polyepoxy compound, b) 1.3-6 parts of a multifunctional compound, c) 0.2 to 1.25 parts of a monoepoxy compound, and d) 0.01 to 0.23 parts of a sultone, wherein the multifunctional compound has four or more active hydrogens. The curing agent obtained has a good hydrophilic effect and very good thinning performance, the paint film prepared by mixing same with an epoxy dispersion has the following advantages: excellent salt spray resistance and water resistance, strong adhesion, high hardness, etc.; in addition, the preparation process of the curing agent is simple, the conditions are mild, and room temperature curing is carried out.
