Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to decorative wood laminates, and more specifically, a small veneer pattern processed into the shape of a natural object is attached to a large veneer board. This invention relates to a wooden decorative board with an embroidered pattern, including the top of the small veneer board.

[Prior Art] Decorative plywood, in which ultra-thin boards called veneers cut from natural wood are laminated on plywood, has been used for furniture such as high-end chests of drawers and sideboards, or for building materials.

These produce natural patterns such as grain patterns, heather, bumps, etc. of natural wood, but by stitching decorative patterns on the wood veneer with various fiber threads, it is possible to prevent cracks on the back of the wood veneer. Wooden decorative boards that reinforce and hide defects such as holes and that also exhibit a variety of patterns on natural wood grains are well known.

This conventional wooden decorative board, which is made by applying embroidery to a wood veneer and pasting it onto a baseboard, can only produce flat embroidery patterns, and has the disadvantage that when the surface is treated with resin, the molten resin seeps into the embroidery thread and stains it. In addition to this, a resin layer with approximately the same thickness as the embroidery thread layer protruding from the back of the veneer was provided only in the areas where there was no embroidery thread, and after the back of the veneer was made approximately flat, it was pasted onto the base plate. Therefore, there was a drawback that the process before pasting was troublesome and workability was poor.

As a solution to these drawbacks, the method proposed by the present applicant and described in Japanese Utility Model Application Publication No. 1983-17'7200 is well known.

In this conventional technology, a small veneer processed into a specific shape is partially temporarily attached to the surface of a large veneer with a backing member attached to the back side of the veneer with thermoplastic adhesive, and both of the veneers are temporarily attached. After embroidering with oil-repellent embroidery thread, a large veneer is pasted on the base plate, a small veneer is pasted on this large veneer, and the thickness of the embroidery thread is pasted on both veneers. This wood decorative board is characterized by having a synthetic resin layer that is sufficiently thicker than that of wood, and the surface of several layers is polished to make it smooth.

[Problems to be Solved by the Invention] In other words, in this prior art, as shown in FIG. 23, when attaching a backing material 2 to a large veneer board 1, adhesive 3 is sprayed onto the backing material 2 to attach it. When trying to attach it to the board 1, the adhesive 3 that has soaked into the backing material 2 sticks to the mold of the press machine, making it extremely difficult to process, and the fabric of the backing material 2 has a lot of adhesive soaked into it. This poses a problem in that a large amount of adhesive must be sprayed in order to increase the amount of adhesive used, which is extremely uneconomical.

For this reason, it is conceivable to spray the adhesive 3 on the back side of the large veneer board 1 and attach the backing material 2 to it, as shown in FIG. Not only is there a problem that the backing material 2 is warped as shown in FIG. 25, making it extremely difficult to apply the backing material 2,
If the amount of spray is too little, the adhesion will be incomplete, and if it is too much, the adhesive will ooze out onto the surface of the veneer, making the surface more likely to have an avatar pattern and increasing the defective rate, which are mutually exclusive problems.

In order to eliminate the above-mentioned problems, the purpose of this invention is to significantly improve the bonding process between a large veneer board and a backing material, and to provide large quantities of decorative wood boards with gorgeous decorative embroidery patterns at a high yield and at low cost. shall be.

[Means for Solving Problem Ii1] The above-mentioned object of the present invention is to provide a backing member bonded under heat and pressure to the back surface of a large-sized veneer board via a thermoplastic sheet; A small decorative veneer board material of a specific shape temporarily attached to the surface of the veneer board material, embroidery performed on both of the veneer board materials with oil-repellent embroidery thread, and a stand to which the large veneer board material is attached with the backing member in between. board and
This is achieved by providing a transparent protective layer that is thicker than the oil-draining embroidery thread formed on both the veneers.

In addition, in the manufacturing method of wood decorative board with embroidered pattern,
After bonding a backing member to the back side of the large veneer board with heat and pressure via a thermoplastic sheet, a small decorative veneer material processed into a specific shape is temporarily attached to the surface of the large veneer board, and the Embroidery is performed on both veneer boards with an oil-draining embroidery thread, the large veneer board is attached to the base plate with the backing member sandwiched in between, and the embroidery is embroidered on both veneer boards with a thickness of the oil-draining embroidery thread. This is also achieved by forming a thick transparent protective layer.

[Function] After bonding a backing member under heat and pressure to the back side of a large veneer board via a thermoplastic sheet, a small decorative veneer material processed into a specific shape is temporarily attached to the surface of the large veneer board. After applying embroidery to both of the veneer boards with an oil-draining embroidery thread, the large veneer board is attached to the base plate with the backing member in between, and the oil-draining embroidery is applied onto both of the veneer boards. By forming a transparent protective layer that is thicker than the thickness of the thread, it is possible to provide a wood decorative board with a gorgeous embroidered pattern at a low cost through automation.

[Example] Examples will be described with reference to the drawings.

As shown in FIGS. 1 and 5, an ultra-thin thermoplastic sheet 14 and a backing member 15 such as soft cloth or Japanese paper are sequentially placed on the back side of a large veneer 13, and as shown in FIG. It is placed on a temporary board for processing as shown in FIGS. 3 and 6, and as shown in FIG. thermoplastic sheet 1
A backing member 15 is firmly adhered to the base plate A as shown in FIG. 4 and FIG.

Next, as shown in FIG. 9, on the surface of the large veneer board 13, an oil-repellent thread 17 is used to sew contour stitches that trace the outline of the decorative veneer board 16, which will be described later and has been processed into a specific shape. Let's do it.

Next, as shown in FIG. 10, a decorative veneer 16 is temporarily attached onto the large veneer 13.

That is, the backing member 22 is pasted on the back side of the large, specific-shaped plywood 21 at the contour sewing location using a thermoplastic adhesive 23, and when the backing member 22 is not pasted, the same adhesive 24 is applied to the surface as well. In this embodiment, a sieved veneer board 16 made from a pine trunk is partially heated and pressed onto the surface of a large veneer board 13 using a heating jig as shown in FIG. 17. and install it.

After this, as shown in FIGS. 12 to 16, embroidery on the ground surface, trunk, branches, and concave parts 18.18 is performed using oil-repellent embroidery thread (gold thread and silver thread) 17 with an embroidery sewing machine. give

5 is placed on a base plate 19 made of peeled board, plywood, tile board, etc. as shown in FIG. It is attached to the board 19.

When this bonding process is completed, as shown in FIG.
As shown in FIG. 9, the polyester resin solvent 72 is applied multiple times with a brush to further reduce surface irregularities.

In this way, a transparent protective layer 20 is formed on the decorative veneer board 25 with an embroidery pattern, and after this protective layer 920 is polished and smoothed with a sand vapor as shown in FIGS. A finishing spray is applied on layer 20 to form protective ffJ20.

Note that as shown in FIG. 22, the backing member 22 is not attached to the back side of the decorative veneer 16, but the decorative veneer 16 is directly attached to the back surface of the decorative veneer 16.
may be adhered to a large veneer board 13 with an adhesive 23.

[Effects of the Invention] Since the present invention is configured as described above and is constructed in a second form, it produces the effects described below.

In the wooden decorative board with an embroidered pattern according to claim 1 or 2, the backing and the batting members can be easily bonded to the large veneer board with an extremely thin thermoplastic sheet, and the adhesive can be applied to the large veneer board. Since no adhesive is applied, large veneer boards do not warp, and there is no need to apply adhesive to the backing member, making press processing easier and eliminating waste of adhesive due to adhesive seepage. Since it is possible to prevent the adhesive from seeping into the large veneer board material, it has the effect of providing a beautiful wood decorative board without an avatar pattern.

In addition to the above-mentioned effects, the transparent and flat protective layer of the present invention allows the uneven pattern on the surface of the decorative veneer and the embroidery thread layer to be expressed in a three-dimensional manner. Beautiful three-dimensional embroidery can be obtained because the molten resin does not seep through, and the adhesive layer that attaches the veneer material to the base plate absorbs the unevenness of the threads on the back side, and the unevenness on the front side is absorbed by the protective layer formed on top. It has the advantage of being easy to process, producing a beautiful three-dimensional pattern with a gorgeous gorge, and being easily mass-produced through automation and being able to be produced at a low price.
