Provided are an epoxy modified acrylic resin and a preparation method therefor, an energy-curable composition containing epoxy modified acrylic resin and application. A branched chain of at least one repeat unit in the acrylic resin is grafted with one or more oxetane groups, and each oxetane group separately has the structure as represented by general formula (I), (II), or (III). After the branched chain of the acrylic resin is covalently grafted with the oxetane group, the epoxy modified acrylic resin is obtained. A coating prepared by using the composition containing the epoxy modified acrylic resin has good flexibility, as well as high adhesion and a great curing film forming speed for a coated substrate. The covalent grafting reaction does not affect the main chain structure of an original acrylic resin, and thus during downstream application, it is not necessary to change original devices and production processes, so that the investment costs are low.
