Embodiment 1
[0028] An energy-saving and environment-friendly UV roller coating method for solid wood doors, comprising the following steps: A, plain board sanding: first use a three-head sander to sand the surface of the door panel, wherein the meshes of the abrasive belts are 120# and 150# respectively , 180#; B, water-based coloring: use a double-roller coloring roller coater to carry out water-based colorant roll coating on the door panel. The agent is a water-based polyurethane coating, and the coating amount of the water-based colorant is 10 g / square meter; C. Drying of the water-based base color: Then, the water-based colored door panel is sent to a hot air drying channel for drying, and the drying temperature is 60 degrees Celsius. Dry time is 2 minutes and deburrs after the water-based base color dries. D. Roller coating of UV putty: first roll the first pass of putty and use LED light for semi-curing, then roll the second pass of putty and use LED light for full curing, and then ...
