Embodiment 1
[0027] A coating process for a matte veneer, comprising the following steps:
[0028] (1) Clean the dust on the surface of the substrate, fill and seal the duct pores of the substrate with UV putty, and the coating amount is 44-46g / m 2 , put the UV putty at an energy of 150-200mJ / cm 2 Drying and curing under the environment, the duct pores of the substrate are filled and closed with UV putty paint for the second time, and the coating amount is 40-50g / m 2 , put the filled and sealed UV putty at an energy of 250-300mJ / cm 2 drying and curing;
[0029] (2) After filling and sealing, sand the surface of the UV putty, clean the dust on the surface of the board, and apply a UV sanding primer with a coating amount of 20-25g / m 2 , the direction of roller coating is two coats along the paint, and the UV sanding primer is applied at an energy of 250-300mJ / cm 2 drying and curing;
[0030] (3) Continue roller coating to make UV sanding primer. The direction of roller coating is one ti...

[0033] A coating process for a matte veneer, comprising the following steps:
[0034] (1) Clean the dust on the surface of the substrate, fill and seal the duct pores of the substrate with UV putty, and the coating amount is 40-50g / m 2 , put the UV putty at an energy of 150-200mJ / cm 2 Drying and curing under the environment, the duct pores of the substrate are filled and closed with UV putty paint for the second time, and the coating amount is 40-50g / m 2 , put the filled and sealed UV putty at an energy of 250-300mJ / cm 2 drying and curing;
[0035] (2) After filling and sealing, sand the surface of the UV putty, clean the dust on the surface of the board, and apply a UV sanding primer by roller coating. The coating amount should be controlled at 20-25g / m 2 , the direction of roller coating is two coats along the paint, and the UV sanding primer is applied at an energy of 250-300mJ / cm 2 drying and curing;
[0036] (3) Continue roller coating to make UV sanding primer. The ...
Embodiment 3
[0039] A coating process for a matte veneer, comprising the following steps:
[0040] (1) Clean the dust on the surface of the substrate, fill and seal the duct pores of the substrate with UV putty, and the coating amount is 40-50g / m 2 , dry and cure the UV putty;
[0041] (2) Roller coat UV sanding primer on the surface of UV putty. The direction of roller coating is to apply once along the direction, and then apply once in the opposite direction. The amount of coating is controlled at 25-30g / m 2 , at an energy of 280-300mJ / cm 2 drying and curing;
[0042] (3) Sand the surface of the UV sanding primer after drying and curing, remove the dust, and roll-coat the UV matte topcoat on the board surface, and the coating amount of the UV matte topcoat is controlled at 30-40g / m 2, and then enter the ultra-matt matting machine for matting. The nitrogen inlet pressure of the ultra-matting matting machine is controlled at 7bar, the nitrogen purity is ≧99%, the temperature must not be...
