Embodiment 1
[0047] Embodiment 1: UV curing wood color paint coating
[0048] 1. Composition of raw materials:
[0049]
[0050] 2. Preparation method
[0051] 1) Weigh each component according to the proportion, disperse JD6080 resin, monomer EO-HDDA, monomer NPGDA, monomer EO-TMPTA, monomer HEA at 1500 rpm for 20 minutes, then add anti-settling under stirring Agent A-200, polymerization inhibitor, dispersed for 10 minutes at 1500 rpm to obtain mixture 1;
[0052] 2) Add photoinitiator 184, TPO, ITX and defoamer BYK-8800 to mixture 1, and disperse for 5-10 minutes at 1200 rpm; then add wetting and dispersing agent BYK-164, substrate leveling agent BYK- 333, disperse at 1200 rpm for 10-15 minutes, then add pigment P-01X and disperse at high speed at 1500 rpm for 20 minutes to obtain the product.
[0053] 3. Coating method: apply the color paint on the substrate (construction process: wooden substrate→UV transparent bottom→full dry sanding→UV color paint). at 320mj / cm 2 (Equipment c...
