の製造方法が提案されている。2. Description of the Related Art Conventionally, in fittings such as indoor doors, kitchen doors, and storage doors, a warp may gradually occur during use due to humidity and temperature. Therefore, in order to prevent warping, generally, doors such as doors are made of a sheet of the same material so as not to warp to one side, a metal support is used for the frame of the fitting, or a decorative plate. Measures are taken such as sticking a sheet having a moisture-proof property, such as a vinyl chloride sheet or a metal foil, on the back side of the. For example, according to Japanese Examined Patent Publication No. 4-7948, an interior material in which a moisture-proof sheet composed of kraft paper / polyethylene sheet / kraft paper is attached to the back surface of a plate-like body is known. The purpose is to prevent moisture from leaking from the interior material to the wall structure and to avoid the formation of condensation within the wall. In addition, Japanese Unexamined Patent Publication No.
According to Japanese Patent No. 272455, a water-impermeable, non-moisture-permeable sheet is attached to both sides of a wooden board, and the wooden board is attached to both sides of a core material made of a wooden base material to propose a method for manufacturing a door that prevents warpage. Has been done.

能が低い扉乃至はドアとなってしまう。Considering this warpage, in the case of a fitting such as a flash door in which a decorative sheet having a decorative sheet adhered to its surface is pressure-bonded, humidity is considered to be a major factor of the warpage, and a sheet with low moisture permeability has a moisture permeability. It is more effective than high seats. For example, a tabling sheet made of a vinyl chloride sheet or a vinyl chloride sheet for a building material (thickness 0.07 mm) has a moisture permeability of 14 to 20 (g / g) in both cases.
m2 · 24h. (JIS Z0208, measurement by cup method)). A door or door that has been flash-processed with a decorative sheet having a vinyl chloride sheet as a decorative sheet on the front surface and a moisture-proof sheet or a vinyl chloride sheet on the back surface has excellent warpage performance. It can be said that this is because the moisture permeability of the vinyl chloride sheet or the moisture-proof sheet is low. On the other hand, in the case of the decorative sheet using the printing paper on the front surface side, the moisture permeability of the printing paper is higher than that of the vinyl chloride sheet, and according to the measurement by the present inventors, in the case of the general coated paper, 350 to 380 ( g / m2
It was 24 h). Therefore, the door or the door has a lower warp prevention performance than the above-mentioned structure.

In the case of a flash door attached to the front and back surfaces of the door member, when the front side is in a high humidity state and the inner side is in a low humidity state, the front side expands due to moisture absorption. On the other hand, the inside shrinks due to drying,
A warp occurs so that it bends inward. FIG.
As shown in (b), even in the case of a flush door in which a decorative sheet having a vinyl chloride sheet having a low water vapor transmission rate as a sheet substrate is attached only to the front side, the front side is also attached to the front and back sides of the door member. When the temperature is high and the temperature inside is low, the inside of the door begins to contract due to drying due to the movement of humidity inside the door, and the inside expands due to moisture absorption. Therefore, a warp that curves in the front direction occurs.

For example, measures such as laminating vinyl chloride sheets and metal foils have been taken, but as the work process increases, material costs and processing costs (for example, metal support mounting, vinyl chloride sheet fee, laminating fee, etc.) ) Increases and the cost increases. Also, in the case of a vinyl chloride sheet, the plasticizer in the sheet may bleed over time and may bleed between the sheet and the adhesive base material to cause poor adhesion.

選択することができる。In the moisture-proof decorative sheet 10 of the present invention, a polyethylene layer, which is a synthetic resin layer 12, is provided on the back surface side of the paper-reinforced paper 11 provided with a printed pattern layer 13 and an acrylic urethane resin layer which is a protective resin layer 14. It is a laminate of inter-paper reinforcing paper 11 not provided with a print pattern layer or the like, and the moisture permeability can be adjusted by the thickness of this polyethylene layer. That is, when the thickness is 15 μm or less, the moisture permeability increases, and the effect of preventing warpage decreases. Further, when the thickness is 50 μm or more, even if the thickness is further increased, the water vapor permeability does not largely change, and a saturated state is obtained, and the warpage preventing effect does not change. Therefore, the thickness of the polyethylene layer is preferably 15 to 50 μm. The protective resin layer 14 is a resin such as an acrylic urethane, a polyester urethane, a polyurethane, a vinyl chloride-vinyl acetate copolymer, an ethylene-vinyl acetate copolymer, etc., which serves as the surface protection of the printed pattern layer, and is synthetic. The polyethylene layer, which is the resin layer 12, is formed by extrusion through a T-die with an extruder. The resin is not limited to polyethylene resin, and any resin having a moisture-proof effect such as polypropylene or polyvinylidene chloride may be used. It can be appropriately selected.

In other words, printing paper with high moisture permeability is used as the sheet base material, but moisture permeability can be adjusted by moisture-proof resin such as polyethylene resin and the extrusion thickness of this resin, and high moisture-proof effect with low moisture permeability. A decorative sheet with Therefore, a printed pattern layer and an inter-paper reinforced paper provided with a protective resin layer on the front surface of the plate base material and an inter-paper reinforced paper with a synthetic resin layer such as polyethylene resin provided on the back surface thereof. A moisture-proof decorative sheet is made by attaching a decorative sheet, and by attaching a moisture-proof sheet for the back side, which is obtained by pasting inter-paper reinforcing paper through a synthetic resin layer such as polyethylene resin, on the back side of the plate base material, It is possible to obtain fittings such as a decorative plate and a flush door that have an improved anti-warpage effect that does not warp even under low humidity conditions. Also, compared with the conventional anti-warping process, the work process is reduced, and the material cost and processing cost (metal support mounting cost, vinyl chloride sheet cost, laminating cost, etc.) can be reduced. Produce the effect.
