貼り替えが容易である。Means for Solving the Problems In order to achieve the above object, a solution of the present invention is to attach two wooden flat plates to both sides of a core, and attach the two wooden flat plates to the opposite side of the wooden flat plate from the core. In a sliding door in which sliding paper is adhered to a surface on which water is applied via an aqueous adhesive, the wooden flat plate has a moisture-proof layer provided on both surfaces of a wooden base material. By adopting this configuration, even if the fusuma paper is adhered or replaced using an aqueous adhesive, the moisture in the adhesive is cut off by the moisture-proof layer provided on the surface of the wooden base material. Therefore, it hardly penetrates into the wooden base material, and therefore, the occurrence of defects such as "lightening" and warping after drying is extremely reduced. In addition, since the movement of moisture inside the sliding door and between the wooden base material and the outside air is prevented, the sliding door that does not warp even if there is a temperature difference or humidity difference between the outside air on both sides of the sliding door. It is possible to Also, it is easy to replace the sliding paper on the surface of the sliding door.

度を発揮する。[0005] Further, the moisture-proof layer is made of a paper-based moisture-proof sheet formed by laminating two thin papers via an extrusion coat layer of a thermoplastic synthetic resin. By doing this, the moisture-proof layer consisting of the extruded coat layer of the thermoplastic synthetic resin is covered with tissue paper on both sides, so that the tissue paper absorbs the adhesive moderately and easily adheres to wood-based substrates and core materials. Thus, an emulsion type adhesive which is safe against fire, has no odor, and is inexpensive is used to exhibit good adhesive strength.

である。The wooden flat plate 2 is composed of a wooden base material 3 and thermoplastic synthetic resin layers 6 disposed on both sides of the wooden base material 3.
The thin paper 5, the thermoplastic synthetic resin layer 6, the thin paper 5, the wood-based base material 3, the thin paper 5, and the thin thermoplastic paper layer are formed by combining the moisture-proof layer composed of the extruded coat layer with the thin paper 5 disposed on both sides of the moisture-proof layer. 6, the thin paper 5 is laminated in this order, and the thin paper 5 is adhered to the reinforcing grid 9 and the wooden base material 3. In the thus constructed anti-warpage sliding door 1, the thermoplastic synthetic resin layer 6 is located on both sides of the wooden base material 3 of the wooden flat plate 2, so that the moisture in the adhesive 8 is reduced by the thermoplastic synthetic resin layer 6.
This reduces the permeation into the wood-based material 3 and prevents deterioration of the design such as “shading”, and also prevents the movement of moisture between the wood-based material 3 and the reinforcing grid 9. At the same time, the movement of moisture between the wooden base material 3 and the outside air is prevented. Therefore, even if there is a difference in temperature and humidity between the outside air on the front side and the outside air on the back side of the fusuma, there is no possibility of warpage. Further, since the moisture-proof layer is formed by sticking the paper-based moisture-proof sheet 4 in which the thin paper 5, the thermoplastic synthetic resin layer 6, and the thin paper 5 are laminated in this order, the manufacturing is simple and inexpensive, and the outermost surface is the thin paper 5.
Made of fusuma paper 7 on the surface to improve the design
It is easy to affix or further to replace the fusuma paper 7.

る。As the thin paper 5 used for the paper-based moisture-proof sheet 4 acting as a moisture-proof layer of the warp-preventing sliding door 1, a printing paper for building materials having a weight of 23 to 50 g / m 2 , pure white paper, or synthetic resin is mixed. A thin paper (a so-called inter-sheet reinforced paper) having enhanced inter-sheet strength is preferably used. 23
When it is not more than g / m 2 , it is too soft and wrinkles are likely to occur during laminating. When it is not less than 50 g / m 2 , it is easily peeled off from the paper layer and moisture easily penetrates. The thin paper to be stuck may be of the same type or different types.

Are polyolefin resins such as polyethylene, polypropylene and ethylene-vinyl acetate copolymer. Further, this thermoplastic synthetic resin layer 6
The moisture permeability can be adjusted by the thickness of
If it is less than μm, the moisture permeability increases, and the effect of blocking the penetration of moisture in the adhesive decreases. On the other hand, when the thickness is 50 μm or more, even if the thickness is further increased, the moisture permeability does not change significantly and becomes saturated, and the effect of blocking moisture penetration does not change. Therefore, the thickness of the thermoplastic synthetic resin layer 6 is 2
About 0 to 50 μm is preferable.

A method of laminating a film of the thermoplastic synthetic resin 6 with an adhesive or using heat without using an adhesive, and simultaneously laminating the layer of the thermoplastic synthetic resin 6 on two thin paper sheets 5 by extrusion lamination. A suitable bonding method is selected according to the type of the thermoplastic synthetic resin 6. When the three layers of the thin paper 5, the thermoplastic synthetic resin 6, and the thin paper 5 are made into three layers as in the present invention, if the three layers are laminated at a time by the extrusion lamination method, the number of steps can be reduced. Like polyethylene, polypropylene,
When a polyolefin-based resin such as an ethylene-vinyl acetate copolymer is used as the thermoplastic synthetic resin, a method in which the thermoplastic synthetic resin is melt-extruded by an extrusion lamination method and laminated at the same time is a suitable method.

る。The above-mentioned paper-based moisture-proof sheet 4 is laminated on both sides of the wood-based substrate 3 with a laminator via a vinyl acetate-based adhesive, thereby preventing the wood-based moisture-proof sheet 4 from being thinned and warped. A flat plate 2 is obtained. At this time, paper-based moisture-proof sheets 4 having different moisture permeability can be used for the paper-based moisture-proof sheet 4 attached to both surfaces of the wood-based substrate 3. the moisture permeability of the moisture-proof sheet 4 20g / m 2 / 24hr or less, that the woody substrate 3 a moisture permeability of paper quality based moisture-proof sheet provided on a surface located between the reinforcing lattice 9 or less 40g / m 2 / 24hr By blocking the penetration of water from the water-based adhesive when applying fusuma paper,
Further, warpage of the sliding door itself can be suppressed. In addition, as the wood-based substrate 3 used in the present invention, a wood-based board substrate such as a wood plywood (including a so-called glued laminated material), a medium density fiberboard (MDF), and a particle board can be used.
