Embodiment 1
[0070] The coating process of the bright paint of embodiment 1 may further comprise the steps:
[0071] Step 1. Sanding the base material. The substrate is sanded to form a panel.
[0072] In step 1, the base material is medium density fiberboard with melamine warm white matte paper pressed on the surface. Substrate density 0.75g / cm 3 .
[0073] In step 1, a three-axis sanding device is used to sand the base material. The sand belts on the three-axis sanding equipment are 240 mesh, 320 mesh and 400 mesh in turn.
[0074] Step 2, the first primer treatment. Step 2 includes three processes.
[0075] (1) The process of roller coating primer. Roller coat the first primer on the surface of the panel. The coating amount of the first primer is 15g / m 2 .
[0076] (2) Primer leveling process. Level the panels. Leveling time 100s. The leveling temperature is 50°C.
[0077] (3), drying and curing process. The first primer is irradiated with a first set of ultraviolet lamps...

[0102] In step 1, the base material is medium density fiberboard with melamine warm white matte paper pressed on the surface. Substrate density 0.79g / cm 3 .
[0103] In step 1, a three-axis sanding device is used to sand the base material. The sand belts on the three-axis sanding equipment are 240 mesh, 320 mesh and 400 mesh in turn.
[0104] Step 2, the first primer treatment. Step 2 includes three processes.
[0105] (1) The process of roller coating primer. Roller coat the first primer on the surface of the panel. The coating amount of the first primer is 20g / m 2 .
[0106] (2) Primer leveling process. Level the panels. Leveling time 200s. The leveling temperature is 60°C.
[0107] (3), drying and curing process. The first primer is irradiated with a first set of ultraviolet lamps....
