The preparation method of the highly water-mark-resistant cathodic electrophoretic emulsion includes the following steps: S1. Blocking some isocyanate groups of toluene diisocyanate with a mixture of n-butanol and PEG400, and then reacting and bonding the unblocked isocyanate groups with oleamide resin and polyamine to obtain a polyamine-modified isocyanate curing agent; S2. Performing a ring-opening amination reaction between epoxy resin and a first amine compound, and then adding a second amine compound to continue the reaction to obtain an amine-modified epoxy resin; S3. Grafting the polyamine-modified isocyanate curing agent onto the amine-modified epoxy resin to obtain a cationic epoxy resin; S4. Neutralizing the cationic epoxy resin with an organic acid, adding deionized water for emulsification and dispersion to obtain the highly water-mark-resistant cathodic electrophoretic emulsion. After electrophoretic film formation, the emulsion exhibits good hydrophilicity on the wet film surface, thereby significantly reducing the formation of watermarks during rapid baking.
