The invention discloses a DOPO type reactive flame retardant with a terminal group as an epoxy group, a preparation method therefor and an application thereof. The preparation method comprises: heating DOPO and a poly(glycidol)-based compound in a reaction molar ratio to react in an organic solvent; and removing the solvent under reduced pressure, thereby obtaining the reactive flame retardant which is a viscous liquid at the room temperature, contains a DOPO flame retardant radical and has the terminal group which is the epoxy group. The flame retardant synthetic method is simple, easy to control, good in repeatability, high in yield, suitable for enlarged production, and can be used as an end-sealed type flame retardant which is applied to flame resistance of a polyurethane material. The flame retardant is applied to the polyurethane material, so that not only are defects of poor compatibility between the added flame retardant and a basal body, easy run-off in a using process and the like overcome, but also a complex process for synthesizing polyhydric alcohols by use of a conventional reactive flame retardant is avoided; and the flame resistance of the material is obviously improved, the oxygen index of polyurethane leather is increased to 26-28%, and the flame retardant level can reach level UL94 V-0.
