A digital inkjet advertising substrate and its preparation method

Abstract

The invention provides a digital printing advertisement base material and a preparation method thereof. The preparation method comprises the steps: preparing anti-ultraviolet hot melt glue for digital printing and putting a base layer on a coil-feeding rack of a coating machine for corona treatment; coating the anti-ultraviolet hot melt glue and drying the base layer at 60-120 DEG C, wherein the thickness of the cooled hot melt glue is 20-100 [mu]m; coating a 10-50 [mu]m thick ink-receptive coating on the cooled anti-ultraviolet hot melt glue, and printing a pattern; carrying out hot press, wherein the pressure is 1-5 kg, the temperature is 120-200 DEG C, the time is 2-50 seconds, and the anti-ultraviolet hot melt glue is melted and permeates among particles of the ink-receptive coating and the printed pattern and covers above and quickly congeals to a film to form a protective layer; and cooling and rolling. The advertisement base material prepared by the invention is bright in pattern, smooth and level, rainproof and sun-proof and strong in anti-ultraviolet ability, and is free of yellowing phenomenon if being used outdoors for one year.
