As a substrate, an artificial wood made of xonotlite, glass fiber, organic polymer emulsion, etc. was used, and the surface of the substrate was 12 m/m thick, 1 m wide, 3 m long, and had a specific gravity of 0.6, with a resin content of 80% and an average molecular weight.
300, a one-component moisture-curing urethane sealer containing a large amount of monomer with 37% or less free isocyanate is diluted 100% with thinner, and the sealer is applied at 92 g/m 2 with a grooved roll and cured. Next, apply a sealing resin paint containing an oligomer-like UV-curable acrylic polyester copolymer and kneading 50-70% extender pigment to improve impregnability.
g/m 2 and presses the paint onto the substrate surface using a reverse roll coater with a working width of 1400 m/m and a load of 100 to 500 kg to apply the filler resin paint under pressure. Next, take a setting time of about 5 seconds and use a high-pressure mercury lamp 80w/cm.
It is cured by irradiating it with ultraviolet light for about 5 seconds at the output of . Then, after sanding with a wide belt sander (grain size #240 to #320) to obtain a smooth surface, remove the abrasive powder adhering to the surface, and reduce the board temperature to 40 to 40 degrees with hot air.
Raise the temperature to 50℃ and apply acrylic urethane enamel paint with a roll coater or flow coater to 90~120℃.
g/m 2 was applied and dried to obtain a decorative artificial wood board made of the calcium silicate board of the present invention.

示し、何れも基板部の破壊であつた。 In the above, the artificial wood that serves as the substrate is a well-known laminated calcium silicate board, but the internal structure is porous with no directionality, and the artificial wood is made of acicular crystals of xonotlite and glass fibers. Because the structure uses an organic polymer polymer emulsion to strengthen the surface strength, the one-component moisture-curing urethane sealer has a low molecular weight, a high resin content, and a large amount of monomer. This increases the impregnating properties and surface reinforcement properties for the substrate, and since the sealing resin paint also contains an oligomer component, it has the ability to penetrate into the sealer layer and has some elasticity, which will not impede the performance of the substrate. It also passed the dry heat repetition test, and when the plane tensile strength between the coating film and the substrate was measured, it was 4 to 7 kg/cm 2 , indicating that the substrate portion was destroyed in both cases.

As described above, since the decorative board of the present invention has been subjected to a stable base treatment, it is possible to provide a decorative board made of high quality and durable artificial wood that does not peel or deform even after long-term use. be.
