44g/m 2 In this way, when forming the composite veneer 5, a water-absorbing substance was mixed into the adhesive used to laminate the material veneers 2 and 2', so that Figure 2, which shows the - line cross section of Figure 1H, As shown in the figure, on the surface of the composite veneer 5, the paint film 7a is not formed on the part corresponding to the adhesive layer 5a of the composite veneer 5 due to the suction action of the paint by the water-absorbing substance contained in the adhesive, and therefore each material Veneer 2,
Not only is an uneven pattern formed along the wood grain pattern represented by the cut surface of the laminated layer 2', but also the adhesive layer 5 is formed on the side where the adhesive layer 5a inclines and infiltrates.
Since a gradually moves away from the surface layer toward the bottom surface, the suction effect of the paint weakens accordingly, and the thickness of the coating film 7a gradually increases as it moves away from the surface layer adhesive 5a, and conversely, the adhesive layer 5a gradually moves away from the surface layer. On the side, since there is no adhesive layer 5a in the lower layer, the gradual increase phenomenon of the paint film 7a does not occur on the surface layer, and the texture of the material such as natural zelkova wood, which has gentle grooves 8b along the tree ring line 8a, is faithfully reproduced. be able to.
なお、吸水性物質を混合した接着剤は水溶性、

物質による塗料の吸い込みに支障をきたすことは
ない。 Note that adhesives mixed with water-absorbing substances are water-soluble,
Both non-water-soluble adhesives can be used, but it is necessary to evaporate the solvent before the surface painting process, and if the adhesive layer is almost dry, water-absorbing substances may interfere with the absorption of the paint. It won't happen.
また、スライス工程では、フリツチを蒸煮等に
より高含水率状態にしてスライスするのが好まし
い。ただし、スライス後は、吸水性物質の塗料の
吸い込みがわるくならないように、得られた複合
単板をよく乾燥させておくことが必要である。 Further, in the slicing step, it is preferable to bring the fritchi to a high moisture content state by steaming or the like before slicing it. However, after slicing, it is necessary to dry the resulting composite veneer well to prevent the water-absorbing substance from absorbing the paint poorly.
複合単板の乾燥は、複合単板を台板上に貼着す

により接着剤の溶剤等が蒸発するので、吸水性物
質の塗料の吸い込み作用が低下することはない。 Drying of the composite veneer is performed in a drying room or the like before or after pasting the composite veneer onto the base plate. Since the solvent of the adhesive and the like evaporates through such drying, the ability of the water-absorbing substance to absorb the paint does not deteriorate.
フリツチを得るための素材単板の積層枚数は、
通常200枚程度であるが、必ずしもこれに限定さ

整可能である。 The number of layers of material veneer to obtain fritchi is:
The number of sheets is usually around 200, but it is not necessarily limited to this and can be arbitrarily adjusted depending on the production scale.

という効果を有する。 As described above, the method for manufacturing artificial decorative veneers of the present invention includes a fritch forming step in which a plurality of raw material veneers are laminated and pressure-bonded using an adhesive containing a water-absorbing substance to obtain a frit; a slicing step for obtaining a composite veneer by slicing the frits in a direction intersecting the laminated surface; a pasting step for attaching the composite veneer onto a base plate via an adhesive; Since it involves a surface painting process in which the surface is painted, it is expressed by the laminated cut surface of the material veneer due to the suction effect of the paint in the adhesive layer of the composite veneer due to the surface painting process of the composite veneer. A thin part of the paint film is formed along the wood grain pattern,
The present invention has the effect that an artificial decorative veneer with a material surface having a three-dimensional appearance that closely resembles that of natural wood can be obtained through an extremely simple process.
