The invention discloses a method for synthesizing a novel amphoteric slow-breaking quick-setting asphalt emulsifier, belonging to the technical field of organic chemical synthesis. The method comprises the following steps of: reacting oleic acid with polyamine to generate acid amide polyamine, and then adding chloroactic acid to generate halogenating reaction to prepare the asphalt emulsifier, wherein the polyamine is the mixture of diethylenetriamine and triethylene tetramine.
