Abstract

The invention discloses a full-UV coating system for a wooden door, a preparation method and a coating process. The full-UV coating system comprises UV spraying transparent primer, UV spraying embellishing essential oil and UV spraying matte transparent finish paint. The invention belongs to the field of novel ultraviolet curing materials, and particularly provides a coating which is formed by adopting multiple times of coating, combining UV spraying transparent primer, UV spraying embellishing essential oil and UV spraying matte transparent finish paint and forming films respectively through ultraviolet curing, so that a wooden door is strong in coloring brilliant feeling, and the coating is high in hardness and transparency. The full-UV coating system for the wooden door, the preparation method and the coating process have the advantages that the full-UV coating system is simple in structure, outstanding in matte effect and fine and smooth in hand feeling.

Description

technical field [0001] The invention belongs to the field of ultraviolet curing new materials, and specifically relates to a full UV coating system for wooden doors, a preparation method and a coating process. Background technique [0002] Ultraviolet radiation curing technology is a brand-new green environmental protection technology. The ultraviolet light curing coating produced by this technology is called UV coating for short.
