The invention discloses a low-shrinkage dual-curing active monomer and a preparation method thereof. The monomer contains both double bonds and an oxetane structure, oxetane can participate in cationic curing, and the double bonds can participate in free radical curing, and the curing activity is relatively high; meanwhile, the oxetane structure has the volume expansion capability in a curing process, and for the monomer with the structure, a volume shrinkage effect achieved by polymerization of the double bonds of the monomer can be canceled by effectively utilizing an expansion effect achieved during ring opening of the oxetane, so that the volume of the whole monomer is prevented from being greatly shrunk after polymerization crosslinking, the coating stress is reduced, and the adhesive force is improved. The preparation method for the monomer comprises the following steps: reacting ethanol with (methyl) acryloyl chloride, performing washing with alkali liquor and a salt solution, and performing spin-drying to obtain a target product. The preparation method is simple and high in yield, and the reaction is stable and easy to control.
