Along with the continuous improvement of the external opening level and the living standard of people, the demands for high-end solid wood furniture are also continuously increased. The high-end solid wood is a precious material, has beautiful textures and soft visual effects, is a continuous pursuit of researchers how to deeply excavate the value, and has the defects of easy water absorption, dirt resistance, easy mildew, aging, color change and the like. The common solid wood furniture mainly aims at protecting effect and practical effect, and the high-end solid wood furniture is required to have protecting and practical effects and is more attractive. Therefore, extremely dumb (glossiness lower than 3 °), thin, transparent effects are produced. The paint film is thin, transparent and very dumb, has a film like no film, can fully show the original taste and flavor of wood, and gives people natural comfort. The extremely matt and thin penetration of a paint film are a pair of contradictory properties, and in general, the lower the gloss (matt), the poorer the transparency.
The traditional extinction method is to add extinction powder, and the extinction powder is usually fumed silica, but the fumed silica has larger refractive index difference with matrix resin, and the compatibility is poor, so that the transparency is affected. Therefore, the gloss is less than 3 ° and the penetration effect cannot be achieved only by adding the matting powder. In addition, the common polyurethane matte varnish solid wood furniture has the defects of uneven gloss, bloom and the like in side view.
