Abstract

PURPOSE:To make it possible to repair easily a defect such as a resin line, a resin mark and a crack by closing the defect by sticking the rear face side of the defect with a thin sheet which can be colored and making the thin sheet to be the same color as that of the surface of a veneer by coating the thin sheet from the surface side. CONSTITUTION:At first, coloring and bleaching treatments which colors a sliced veneer obtd. by slicing a wood and bleaches a resin part thereof are performed. Then, WPC treatment of colored and bleached veneer 1 is performed and for those WPC-treated veneers 1 which have a defect 2 such as a resin line, a resin mark, a crack, the rear face side of the defects 2 of the veneer 1 is stuck with a thin sheet 3 which can be colored to close the defect 2 and then, the thin sheet 3 is coated with a coating having the same type of color as that of the surface of the veneer 1 from the surface side to finish it to the same color as that of the surface of the veneer 1. After the defect 2 of the veneer 1 is repaired by doing like this, the veneer 1 wherein the defect 2 has been repaired is laminated and pressed on the base sheet 4 through an adhesive 5 and then, processes such as cutting work and practical works are performed and finally, coating finish is performed to form a surface coating layer 7 and to form a wooden decorative sheet 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of resin strips of veneers such as sliced veneers, resin pots,
This invention relates to a technique for repairing damaged parts such as cracks.

[Conventional Art] Conventionally, so-called sliced veneers, which are made by slicing wood into veneers, have been used as decorative veneers.

[Problems to be Solved by the Invention] Incidentally, sliced veneers obtained by slicing wood as described above sometimes have defects such as so-called resin lines, resin spots, and cracks. Sliced veneers with cracks have low commercial value and end up being low-grade products. In particular, coarse wood species (
For example, in the case of straight-grained coniferous wood, the sliced veneer tends to have defects such as the above-mentioned resin lines, resin spots, and cracks.

The present invention was invented in view of the problems of the prior art described above, and its purpose is to
To provide a method for repairing a defective part of a veneer, which allows the repair of a defective part such as a crack by a simple method.

[Means for Solving the Problems] The method of repairing a defective part of a veneer according to the present invention includes a method for repairing a defective part of a veneer 1,
A thin sheet 3 that can be colored is pasted on the back side of the defective part 2 such as a tar pot or a crack to close the defective part 2, and the thin sheet 3 is applied from the front side.
It is characterized by painting the surface of the veneer 1 in the same color as the surface of the veneer 1, and by adopting such a configuration, the problems of the conventional example described above can be solved and the object of the present invention can be achieved. This has been achieved.

[Function] According to the present invention, the thin sheet 3 is attached to the back side of the defective part 2 of the veneer 1, and the defective part is removed by applying the same color to the veneer 1 from the front side of the thin sheet 3. 2 to w4m and color repair on the surface.

[Embodiments] The present invention will now be described in detail based on embodiments shown in the accompanying drawings.

Sliced veneer is obtained by slicing wood.9 Normally, after coloring or bleaching the sliced veneer, such as coloring or bleaching the tar, the veneer 1 is subjected to WP treatment.
C treatment, and adhere this WPC treated veneer 1 to the substrate 4.
The wood decorative board 6 is laminated and pressed through an i5, then subjected to various processing such as cutting and actual processing, and finally painted to form a surface coating layer 7. Incidentally, the sliced veneer used to form the wood decorative board 6 as described above may have defects 2 such as resin lines, resin spots, and cracks, but in the present invention, the veneer 1 is The defects 2 such as resin streaks, resin pots, and cracks that have occurred are repaired as follows.

That is, first, the sliced veneer obtained by slicing the wood is colored and bleached by coloring the sliced veneer and bleaching the tar part. ), then the colored and bleached veneer 1 is treated with WPC, and then the WPC treated veneer 1 is treated with resin as shown on the left side of FIG. If there are missing parts 2 such as streaks, tar spots, cracks, etc., first,
As shown in the center of FIG. 1, a colorable thin sheet 3 is pasted on the back side of the defect 2 of the veneer 1 to close the defect 2, and then, as shown in the right side of FIG. As shown, a paint 8 of the same color as the surface of the veneer 1 is applied to the thin sheet 3 from the front side to finish it in the same color as the surface of the veneer l (in the one shown on the right side of Fig. 1). For convenience, the painted parts of thin sheet 3 are shown with cross hatching),
After repairing the defective part 2 of the veneer 1 in this way, the veneer 1 with the repaired defective part 2 is laminated and pressed onto the substrate 4 via the adhesive 5, and then processing such as cutting and actual processing is performed. Finally, a coating finish is applied to form a surface coating layer 7 to form a wood decorative board 6.

FIG. 2 shows a cross-sectional view of the wooden decorative board 6 obtained in this manner. By the way, in the method of the present invention, a nonwoven fabric of 20 to 60 microns, for example, is used as the colorable thin sheet 3 that is applied to the back side of the defective part 2 of the veneer 1 to cover the defective part 2. The nonwoven fabric used as the thin sheet 3 may be coated with or impregnated with a thermoplastic resin. In addition, in the above pressing process, when laminating and pressing the veneer 1 with the repaired defective part 2 onto the substrate 4 via adhesive, the same color as that applied to the thin sheet 3 for repair is used as the adhesive. When using colored adhesives, even those using veneer 1 with defects [2]
This improves the hiding effect of the substrate 4.

In the above-mentioned embodiments, after coloring and bleaching the sliced veneer with defects 2 such as resin streaks, resin pots, cracks, etc., the veneer is further subjected to WPC treatment, and then the veneer is treated with WPC, and then the veneer is treated with WPC. If the defective part 2 is repaired, but there is a defective part 2 in the sliced veneer without coloring, bleaching or WPC treatment, repair the defective part 2 according to the method of repairing the defective part 2 of the present invention. [Effects of the Invention] In the present invention, as described above, a thin sheet that can be colored is applied to the back side of defects such as tar lines, tar pots, cracks, etc. of the veneer. A thin sheet is pasted on the back side of the defective part of the veneer, and a thin sheet is painted from the front side to the same color as the surface of the veneer. The defective part of the veneer can be closed and repaired by a simple method of coloring the veneer in the same color as the board, and the decorative veneer can be made into a decorative veneer with improved appearance and high commercial value.

Claims (1)

[Claims] (1) Paste a colored thin sheet on the back side of defects such as tar streaks, tar pots, cracks, etc. on the veneer to close the defects, and then paint the thin sheet from the front side to make the surface of the veneer A method for repairing damaged parts of a veneer, characterized by making them the same color.
