Dual-layer laminating method of environment-friendly corrugated paper printer

The invention discloses a dual-layer laminating method of an environment-friendly corrugated paper printer. The method comprises the following steps that firstly, a corrugated paper board to be laminated is transferred to a feeding conveying belt; secondly, on the feeding conveying belt, the upper face and the lower face of the corrugated paper board are preheated, the heating temperature is T1, and Ti is larger than 45 DEG C and smaller than 60 DEG C; thirdly, the corrugated paper board falling into a discharging conveying belt from the feeding conveying belt is subjected to dual-face laminating liquid spraying; and fourthly, through the discharging conveying belt, the corrugated paper board is conveyed out. The corrugated paper obtained after dual-face spraying and laminating is baked before entering the discharging conveying belt, and the baking temperature is T2 and is larger than 45 DEG C and smaller than 60 DEG C. Through the spraying method, the corrugated paper board is subjected to dual-face laminati
