Some embodiments of the invention provide a manufacturing device and method for modified petroleum resin. The manufacturing device comprises: a mixer; a twin-screw extruder communicated with the mixer, wherein the outlet of the mixer is connected to the inlet of the twin-screw extruder; a devolatilizing kettle communicated with the twin-screw extruder, wherein the outlet of the twin-screw extruder is connected to the inlet of the devolatilizing kettle; a recovery tank communicated with the devolatilizing kettle, wherein the first outlet of the devolatilizing kettle is connected to the inlet of the recovery tank; and a condenser communicated with the recovery tank, wherein the first outlet of the recovery tank is in bidirectional communication with the inlet of the condenser. An electron beam irradiation device is arranged at the twin-screw extruder. The invention adopts the synergistic effect of twin-screw extrusion and electron beam irradiation to graft polar monomers, and uses the strong shearing force of the twin screws to fully mix the petroleum resin and the polar grafting monomers.
