Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.

A plurality of material veneers are laminated with an adhesive and bonded by pressure using a concave-convex mold to obtain a concave-convex deformed frit, and this concave-convex deformed frit is sliced at a predetermined slice plane that intersects with the laminated surface to form the above-mentioned material on the material surface. In the conventional manufacturing method of artificial decorative veneer, which produces an artificial decorative veneer that expresses a board-like wood grain pattern in which the cut surface of each material veneer resembles the annual ring layer, it is necessary to Subtle wood grain patterns, such as the so-called shaded heather pattern, which has a slightly lighter tone along the heather pattern, cannot be reproduced, and the resulting artificially decorated veneer lacks a natural feel.

Therefore, an object of the present invention is to provide a method for manufacturing artificial decorative veneer that is easy to manufacture and can easily reproduce subtle wood grain patterns found in natural wood, such as a shade pattern.

An embodiment of the invention is shown in FIGS. 1A to 1D. In other words, the method for manufacturing this artificially decorated veneer is as follows:
A material veneer 1 dyed in autumn wood color is impregnated with resin in the longitudinal direction of the intermediate region using a coating means such as a flow coater or a roll coater as shown in FIG. 1A, and this resin impregnation is applied. Processing area 1
As shown in Figure B, the material veneer 1 having the color a and the material veneer 1' which has been dyed in the spring wood color and which has not been subjected to the resin impregnation treatment are laminated together with an adhesive as shown in FIG. A concave-convex deformed frit 3 as shown in FIG. The cut surfaces of each material veneer 1 and 1' are curved on the wood surface as shown in Figure D by slicing along a predetermined slice plane S that intersects with the veneer S, thereby creating an artificial pattern that resembles the grain pattern of natural wood. A decorative veneer 4 is obtained.

In this way, the material veneer 1 has been dyed in the color of autumn wood.
A resin-impregnated region 1a is formed in the longitudinal direction of the intermediate region that undergoes uneven deformation by pressing with the uneven mold 2, and is combined with a material veneer 1' dyed with spring wood color that is not subjected to resin impregnation treatment to cause uneven deformation. Since the fritches 3 are obtained and the unevenly deformed fritches 3 are sliced into a grain pattern, the curved portion 4a of the grain pattern on the material surface of the artificial decorative veneer 4 corresponding to the resin impregnated area 1a of the material veneer 1 has the following properties: In the slicing process, as shown in FIG. 2, the autumn wood layer 4b is impregnated with resin and has increased hardness (consisting of a veneer of material dyed in autumn wood color).
The spring wood layer 4c (made of a veneer of material dyed in the color of spring wood), which is softer than the spring wood layer 4c, is deeply gouged, and at the boundary between the autumn wood layer 4b and the spring wood layer 4c, the fall wood layer 4c is softer than the thinner part of the spring wood layer 4c. The wood layer 4b is transparent, and as shown in FIG.
A region lighter in color than the dark dyed region is expressed along the dark dyed region, and the shaded heather pattern seen along the real heather pattern in natural wood can be expressed by this light colored region.

Other specific conditions in this example are as follows.

Material veneer: White canaryium (thickness: 1.0mm, 0.8mm) Impregnated resin: Polyester, coating amount 50g/m Combination of ² material veneers: Resin-impregnated veneer Quantity: Number of non-impregnated veneers = 1 :1 In addition, as the impregnating resin, urethane,
Resins such as epoxy, urea, phenol, acrylic, etc. can also be applied.

In addition, if the uneven deformation areas of the material veneer are dispersed or if you want to randomize the appearance location of the shade pattern, the resin-impregnated regions 1a of the material veneer 1 may be scattered as shown in Fig. 3. This makes it possible to express the desired shade pattern.

As described above, in the method for manufacturing artificial decorative veneers of the present invention, a plurality of material veneers are laminated with an adhesive and bonded by pressure using an uneven mold to obtain an uneven deformed fritz. In a method for producing artificial decorative veneer in which grain slicing is performed on a predetermined slice plane that intersects with the lamination plane, the lamination of the raw material veneer is
Because it is a combination of a material veneer whose areas corresponding to uneven deformation have been impregnated with resin and a material veneer which has not been impregnated with resin, a grain pattern with a shade pattern can be expressed on the material surface through an extremely simple process. This has the effect that it is possible to obtain an artificially decorated veneer with a natural feel.
