description A preparation method for an emulsifier, an emulsifier, an aqueous epoxy resin dispersion, and a formulation method. The preparation method for an emulsifier comprises reacting aminosulfonic acid and/or a sulfamate as a first reaction raw material with an epoxy resin in the presence of water, so as to obtain an ionic active emulsifier. The ionic active emulsifier molecule comprises at least one epoxy group from an epoxy resin and at least one sulfonic acid or sulfonate group from the first reaction raw material. The aqueous epoxy resin dispersion prepared by using the emulsifier has the characteristics of good stability and good corrosion resistance after curing, and can be used in the fields of coatings, adhesives, etc.
