Abstract

Objective In order to provide a basis for the powder coating of reed-based particle board, this study explored the surface characteristics of reed-based particle board and its influence on the finishing effect of epoxy polyester powder coating.
Method A kind of epoxy polyester powder coatings had been selected in this article, which was applied to reed-based particle board by electrostatic spraying, and cured at 130 ℃ in 3 min. On the basis of characterizing the curing behavior of coating and the surface properties of reed-based particle board, the effect of sanding treatment on the surface properties of the panel and the finishing properties of powder coatings was studied.
Result The particle size of selected powder coatings which could cure at 130 ℃ was 31.5 μm on average. The sanding process could remove the procuring layer and the increasing of sandpaper mesh could improve the roughness and wettability of the reed-based panel. The effect of treatment of sanding mesh 240 was the best within the selected range of the experiment. The average thickness of coating formed by finishing was 125.4 μm. The coating adhesion grade of the powder coating was 0, and the hardness was more than 3 H. With the increase of sand mesh, the leveling property of powder coating on substrate surface was improved.
Conclusion Reed-based particle board with the treatment of sanding mesh 80, 120, 180 and 240 has good bonding performance and appearance quality with epoxy polyester powder coating. This method can be used for reed-based particle board powder coating.
