The invention provides waterborne wear-resisting ultraviolet-cured glazing oil and a preparation method thereof. Epoxy resin is subjected to ring opening by the amino of an amino siloxane coupling agent, and is subjected to polymerization with diisocyanate, a chain extender and hydroxyl acrylate to prepare modified polyurethane acrylate waterborne light-cured resin, and is stirred with various aids to obtain a target. A siloxane group is introduced into a resin main chain structure, so that the wear resistance and the water resistance of the glazing oil are improved; a dry film of the glazingoil has the 100-circle wear of less than 0.1 g, and does not foam or fall after soaking in water for 10 hours. An epoxy resin structure is introduced, so that the initial tack of the glazing oil to print ink is improved. Through small molecules and an internal crosslinker chain extender, an obtained flexible chain structure resin ensures the adhesion and the flexibility of the glazing oil on the ink, the folding number of the dry film of the glazing oil is 16 to 20, and the adhesion is 0 to 1 level. An active monomer diluent is not used, toxic and harmful substances of methylbenzene or dimethylbenzene are free, and a paint film does not have a diluent residual, and is environment-friendly.
