うにしたシート状ツキ板に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) This invention is a sheet-shaped veneer used for wall materials, flooring, and other decorative surfaces that does not warp due to dryness, humidity, temperature changes, or changes over time. It is related to plywood.
(従来技術)
近時自然木を薄くスライスしたツ千板は合成木質板等に
貼着して壁材、床材として使用され前1士ツキ撥を直接
什F面に張込んで化粧面として使用されている。(Prior art) Recently, tsusenban, which is made by thinly slicing natural wood, is used as a wall material or flooring material by pasting it on synthetic wood boards, etc., and it is also used as a decorative surface by directly pasting it on the floor surface. It is used.

っても尚反りが出る状態であった。However, since the veneer above is made of natural wood, the residual moisture content is 5~5.
Even if a 20%wt dry veneer is pasted, it will warp due to dryness during adhesion, drying and wetting of residual internal stress in the wood, changes in temperature of the structure, and changes over time, or if the veneer itself is thin. Also, the fleshy part between the grains of the tree rings and the grain part have different tissue densities, so due to dryness, humidity, temperature changes, and changes over time, they become wavy along the wood grain, making it suitable for use as flooring and wall materials. There are major problems such as warping when the veneer is bonded, and peeling when bonded (hot melt).To solve this problem, it is necessary to remove the internal stress of the veneer. Dry thoroughly.・There are methods such as making the veneer extremely thin or breaking the fibers within the veneer,
Even after drying, 5 minutes of water always remains in the wood structure, and it is impossible to turn the residual moisture into O2.Also, it is impossible to make ultra-thin veneer from veneer, and the fibers cannot be broken. Even if it was applied to a considerable extent, it still warped.

そこで上記の中のツキ板を極薄状にすることについては
単板のツキ板1を合成樹脂フィルム2に貼着し、これを

あった。(Problem to be solved by the invention) Therefore, in order to make the veneer board in the above-mentioned ultra-thin shape, it is possible to attach the veneer veneer 1 to a synthetic resin film 2 and sand it. However, as shown in FIG.
The area between the two sides is uneven and wavy, so if you sand it in this state, the image area will be removed too much, and in some cases, the two sides of the film on the back may be exposed.

ある。(Means for Solving the Problems) The present invention was provided to solve the above problems, and includes a thin veneer board 1 and a cellulose-based fine powder aggregate 4.
Contains 1. A thin film 2 of thermoplastic synthetic resin is bonded to the thin film 2 of the thermoplastic synthetic resin, and after being rolled from both sides, the veneer 1 is formed into a sheet-like veneer with the surface 1a removed by sanding to form an extremely thin sheet. The residual stress within the veneer 1 is removed to prevent warping.
尚、揉込み加工はツキ板1とフィルム2゛との接着が完
全に終了する接着剤の硬化完了前が理想的である。Note that the rubbing process is ideally performed before the adhesive is completely cured and the adhesion between the veneer 1 and the film 2 is completely completed.

は波打ちや反りがなく、平板状となるので、ツキ板1の
表面1aにサンディングが全面的に平均して行われ極薄
状とすることができる。(Function) Since the film 2 contains the cellulose-based fine aggregate 4, the veneer 1 and the thermal Tf'r plastic synthetic resin film 2 are bonded together and do not peel off, and can be rolled from both sides. Therefore, the tissue density of the hard part of the wood veneer 1 with high tissue density becomes low and becomes soft, and the whole becomes uniform.Also, by being rubbed, the outer covering of the cell nuclei of the wood is destroyed, and especially in the soft tissue, the cell nuclei are mutually separated. (1) The internal stress is removed and the veneer 1
Since the veneer 1 has a flat plate shape without waving or warping, the surface 1a of the veneer 1 can be sanded evenly over the entire surface, making it extremely thin.
又サンディングによってツキ板1の組織密度の高い木目
10部分が特に削り取られ、几つ木材の組織相互の繋り

たりすることなく張り易い。Also, by sanding, the wood grain 10 part with a high texture density of the veneer board 1 is particularly removed, and the connection between the textures of the fine wood and the thickness are lost, so the direction of the warp cannot be determined and the residual stress is the backing material. The drag force is equal to or lower than that of the film 2, and warping is prevented. Furthermore, since the veneer l is inserted into the synthetic resin film 2 in a state that is thicker than the final desired thickness, it can be easily stretched without tearing or tearing.

である。11はガイド板である。The veneer board 1 is made by slicing natural wood to 0.1 to 0.3 mm.
The film 2 is a semi-hard film made of thermoplastic synthetic resin such as nylon or Teflon, or a soft film such as PVC and contains cellulose-based fine powder aggregate 4. , 0.1 to 1.0 mm thick, and as shown in FIG. Until the adhesive hardening of the decorative sheet A is completed, as an example, the back side of the decorative sheet A is rubbed through a sampling machine 5 as shown in Fig. 4. be. The adhesion between the veneer board 1 and the film 2 is performed by roughening the surface of the film 2 by sanding to expose the fine aggregate 4 contained in the film 2 at the core, as shown in FIG. In some cases, the adhesion can be strengthened. The sampling machine 5 has a plurality of rolls 6 with a diameter of 10cII + front and back arranged in parallel at equal intervals at the bottom.
A plurality of rolls 7 each having a diameter of about 10 cm are arranged in parallel between each roll 6 with their circumferential surfaces close to the roll 6 above, and a belt 8 is wound around six rows of rolls, and a belt 9 is wound around seven rows of rolls. In the meantime, feed the decorative sheet) A with the grain direction of the veneer board 1 parallel to the roll axis, and bend it alternately in the YY direction, which is perpendicular to the direction of the wood 510 and where warping is likely to occur, from both sides by the circumferential surface of the roll 6.7. It is designed to be rubbed more thoroughly. 11 is a guide plate.

の繋り部分の厚味がなくなり平均化される。(Effects) The sheet-like veneer according to the present invention has the following characteristics: 1. A thin veneer and a thin film of thermoplastic synthetic resin are bonded together, and the thin veneer and the thin film of thermoplastic synthetic resin are bonded together and rolled from both sides, so that the veneer is hard and has a high tissue density. The wood becomes soft and has low density, and the whole wood is evened out, and the outer shell of the wood's cell nucleus is destroyed, the connections between the shells are severed, and the stress that causes internal warping is removed, resulting in a flat plate. Furthermore, since the surface of the veneer is removed by sanding, the texture of the veneer is high,
In addition, the raised wood grain portions are particularly removed, and the thickness of the mutually connected portions of the structures is eliminated and evened out.
従って揉込みとサンディングによって残留応力が裏打材
である合成樹脂フィルムの抗力以下となる。Therefore, by rubbing and sanding, the residual stress becomes less than the drag force of the synthetic resin film that is the backing material.
