The invention relates to the technical field of outer packing carton gloss oil glazing, and discloses an outer packing carton gloss oil glazing process which comprises the following steps: removing dust, paper scraps and other impurities on the surface of an outer packing carton to be glazed through a high-voltage electrostatic dust collection device, controlling the electrostatic voltage to be 30-50kV, and ensuring that the surface of the carton is clean and free of foreign matters; through the synergistic effect of paper box pretreatment, precise coating and gradient curing, the problems of uneven coating thickness and multiple surface flaws of a traditional process are solved, the surface of the coating is flat and smooth, the glossiness can be regulated and controlled according to needs, the adhesive force, the wear resistance and the water resistance of the coating are remarkably improved, and the coating quality is improved. The appearance quality and the protection performance of the carton are greatly improved; and the automatic continuous production process is adopted, the gradient curing technology is combined, the gloss oil drying and curing time is greatly shortened, compared with a traditional technology, the production efficiency is improved by 30%-50%, and meanwhile the manual operation intensity is reduced.
