The proposed method is disclosed in Japanese Patent No. 124128.
この化粧板は、木製基板の表裏両面にそれぞれ極薄の銘
木単板を接着し、各銘木単板の上に厚い塗膜層を形成し
たものである。This decorative board is made by bonding ultra-thin veneers of precious wood to both the front and back sides of a wooden substrate, and forming a thick coating layer on each veneer of precious wood.
このように基板の表裏両面側を同一に構成する理由は、
車室内の温度変化に伴う化粧板の反りおよびその反りに
起因した塗膜層の剥離を防止することにある。The reason why both the front and back sides of the board are configured the same is as follows.
The object of the present invention is to prevent warping of a decorative board due to temperature changes in a vehicle interior and peeling of a coating layer caused by the warping.
（３）発明が解決しようとする課題
しかしながら、前記のように木製基板を用いると、化粧
板の形状における自由度が小さく、また銘木単板を２枚

造コストが高くなる、という改善すべき点がある。(3) Problems to be solved by the invention However, when a wooden substrate is used as described above, the degree of freedom in the shape of the decorative board is small, and it is also necessary to glue two veneers of precious wood together or form two layers of paint. However, there is an issue that needs to be improved in that the manufacturing cost of the decorative board increases.
本発明は前記に鑑み、形状の自由度が大きく、且つ製造
コストが安価で、高品質な前記車両用化粧板を提供する
ことを目的とする。In view of the above, an object of the present invention is to provide the above-mentioned decorative panel for a vehicle that has a large degree of freedom in shape, is inexpensive to manufacture, and is of high quality.

を近似させたことを特徴とする。B9 Structure of the invention (1) Means for solving the problem The decorative panel for a vehicle according to the present invention comprises a synthetic resin substrate, an extremely thin precious wood veneer adhered to the surface of the substrate, and the precious wood veneer. It is characterized in that it has a transparent synthetic resin surface coating layer formed by thick coating on the surface of the substrate, and the linear expansion coefficients of the substrate and the surface coating layer are approximated.
（２）作 用
前記のように基板を合成樹脂より構成すると、化粧板の
形状における自由度が大きくなる。(2) Effect When the substrate is made of synthetic resin as described above, the degree of freedom in the shape of the decorative board increases.
また銘木単板を１枚のみ使用するので、銘木単板のコス
トが半減し、さらに表面塗膜層を一層のみ形成すればよ
いので、塗装コストが半減する。Furthermore, since only one veneer of precious wood is used, the cost of the veneer of precious wood is halved, and since only one surface coating layer needs to be formed, the cost of painting is halved.
その上、基板と表面塗膜層との線膨脹率を近似させたの

速めることができる。As shown in FIG. 8(d), a precious wood VI 20 made of Myrtle is polymerized on top of the resol adhesive 19 with its flexible reinforcing film 22 facing down, and the substrate 6 is formed using a vacuum pressure press. Adhere to surface 7. The heating temperature in this case is 110 to 120°C, and the drying time of the resol adhesive 19 can be accelerated by performing pressure pressing while irradiating microwaves.
前記粗面化に伴いレゾール系接着剤１９に対する大きな
アンカ効果が得られるので、銘木単Ｉｔｊｉ２０の接着
強度が高くなる。Due to the roughening of the surface, a large anchoring effect is obtained for the resol adhesive 19, so that the adhesive strength of the precious wood single Itji 20 is increased.
この接着工程では、柔軟性補強フィルム２２を貼着した
銘木単板２０を用いるので、折曲げ緑ｌＯの外周面へも
銘木単板２０をそれに割れを生じることなく撓ませて接
着することができる。In this bonding process, since the precious wood veneer 20 to which the flexible reinforcing film 22 is attached is used, the precious wood veneer 20 can be bent and bonded to the outer peripheral surface of the bent green lO without causing any cracks. .
また補強フィルム２２により銘木単板２０へのレゾール
系接着剤１９の浸透が阻止されるので、後工程において
銘木単板２０に対する表面塗膜層２１の付着性を良好に
することができる。Furthermore, since the reinforcing film 22 prevents the resol adhesive 19 from penetrating into the precious wood veneer 20, the adhesion of the surface coating layer 21 to the precious wood veneer 20 can be improved in a subsequent process.
その後、基板６に沿って銘木単板２０にトリミング加工
を施し、また脇に食出している接着剤１９を除去する。Thereafter, the precious wood veneer 20 is trimmed along the substrate 6, and the adhesive 19 protruding on the sides is removed.
