Example Embodiment
[0036] Example 1
[0037] In this embodiment, the production process of environmentally friendly laser cardboard sequentially includes the following steps:
[0038] (1) Use a corona machine to corona treat the cardboard surface (the side that needs to be coated with laser imaging paint). After corona treatment, the dyne value of the cardboard surface is 40; the cardboard uses gold cardboard;
[0039] (2) Use a coating machine to evenly coat a layer of laser imaging paint on the cardboard, and the laser imaging paint is dried and cured (using hot air drying, the temperature of the 5 drying sections of the drying channel is set to 90℃, After 110°C, 125°C, 110°C, 90°C), a transparent surface coating is formed on the cardboard, the thickness of the transparent surface coating is 2.0μm; then the cardboard with the transparent surface coating is cooled by a cooling roller ( The cooling temperature is 20℃); then the rewinding device rewinds the jammed paper;
[0040] (3) Use a laser mold pl...

[0054] Example 2
[0055] In this embodiment, the production process of environmentally friendly laser cardboard sequentially includes the following steps:
[0056] (1) Use a corona machine to corona treat the cardboard surface (the side that needs to be coated with laser imaging paint), and the dyne value of the cardboard surface after corona treatment is 50; the cardboard is silver cardboard;
[0057] (2) Use a coating machine to uniformly coat a layer of laser imaging paint on the cardboard, and the laser imaging paint is dried and cured (using hot air drying, the temperature of the 5 drying sections of the drying channel is set to 95 ℃, After 120°C, 135°C, 120°C, 95°C), a transparent surface coating is formed on the cardboard, the thickness of the transparent surface coating is 4.0μm; then the cardboard with the transparent surface coating is cooled by a cooling roller ( The cooling temperature is 10℃), after cooling, the jammed paper is reeled by the reeling device;

[0072] Example 3
[0073] In this embodiment, the production process of environmentally friendly laser cardboard sequentially includes the following steps:
[0074] (1) Use a corona machine to corona treat the surface of the cardboard (the side that needs to be coated with laser imaging paint), and the dyne value of the cardboard surface after corona treatment is 45; the cardboard is white cardboard;
[0075] (2) Use a coating machine to evenly coat a layer of laser imaging paint on the cardboard, and the laser imaging paint is dried and cured (using hot air drying, the temperature of the 5 drying sections of the drying channel is set to 90℃, After 115℃, 130℃, 115℃, 90℃), a transparent surface coating is formed on the cardboard, the thickness of the transparent surface coating is 3.0μm; then the cardboard with the transparent surface coating is cooled by a cooling roller ( The cooling temperature is 15℃), after cooling, the winding device will rewind;
