The invention discloses a preparation method of waterborne polyurethane based on glycidyl methacrylate. The preparation method comprises the following steps: firstly carrying out a reaction between diisocyanate and macromolecular dihydric alcohol, micromolecular dihydric alcohol and a hydrophilic chain extender; adding an end-capping reagent to obtain a double bond-terminated polyurethane prepolymer; and carrying out copolymerization by adding glycidyl methacrylate so as to obtain epoxy group-controllable block cationic waterborne polyurethane. According to the method, the epoxy group is bonded to polyurethane through a chemical bond to form a single component system which is convenient to use, can be used along with amines, polyatomic acid or polyisocyanate compounds for cure-crosslinking, modification and the like and has stronger machinable property. The synthesized block cationic waterborne polyurethane has smaller particle size, narrower particle size distribution and higher emulsion storage stability.
