の製造方法が提案されている。2. Description of the Related Art Heretofore, in fittings such as indoor doors, kitchen doors, storage doors, and the like, there have been cases where warpage gradually occurs during use due to humidity and temperature. Therefore, in order to prevent warpage, doors and other fittings are generally made of a sheet of the same material so that they do not warp to one side, metal fittings are used for the fitting frame, or decorative boards For example, a sheet having a moisture-proof property, such as a vinyl chloride sheet or a metal foil, is attached to the back surface of the sheet. For example, according to Japanese Patent Publication No. 4-7948, there is known an interior material in which a moisture-proof sheet composed of kraft paper / polyethylene sheet / kraft paper is adhered to the back surface of a plate. The purpose is to prevent moisture from leaking from the interior material to the wall structure, and to avoid the occurrence of dew condensation in the wall. In addition, Japanese Unexamined Patent Publication No.
JP-A-272455 proposes a method of manufacturing a door in which a water-impermeable and moisture-impermeable sheet is attached to both sides of a wooden board, and the wooden board is attached to both sides of a core made of a wooden substrate to prevent warpage. Have been.

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 a surface thereof is pressed, humidity is considered to be a major factor of warpage. It is more effective than a high sheet. For example, the water vapor transmission rate of a tabling sheet made of a vinyl chloride sheet or a vinyl chloride sheet for building materials (having a thickness of 0.07 mm) is 14 to 20 (g / g).
m 2 · 24h. JISZ0208, measurement by the cup method). A door or door that has been flash-processed with a decorative sheet in which a decorative sheet of a vinyl chloride sheet is attached to the front surface and a moisture-proof sheet or a vinyl chloride sheet is attached to the back surface has excellent performance with respect to warpage. This can be attributed to the low moisture permeability of the vinyl chloride sheet and the moisture-proof sheet. On the other hand, in the case of the decorative sheet using the printing paper on the front 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, it is 350 to 380 ( g / m 2
24h). Therefore, the door or door has lower warpage prevention performance than the above configuration.

In the case of a flash door attached to the front and back surfaces of a door member, when the front side is in a humid state and the inside is in a low-humidity state, the front side extends due to moisture absorption. On the other hand, the inside shrinks due to drying,
Warpage occurs so as to bend inward. FIG.
As shown in (b), even in the case of a flash door in which a decorative sheet in which a decorative sheet made of a vinyl chloride sheet having low moisture permeability is adhered to only the front side is bonded to the front and back surfaces of the door member, When the inside of the door is in a high temperature state and the inside is in a low temperature state, the front side begins to shrink by 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.

不良を起こすことがある。On the other hand, in order to prevent warpage, a metal support is used for a frame of a fitting such as a door.
For example, measures such as laminating a vinyl chloride sheet or metal foil have been taken. However, as the number of work steps increases, material costs and processing costs (for example, mounting of metal supports, vinyl chloride sheet costs, laminating costs, etc.) ) Increases and costs increase. Further, in the case of a vinyl chloride sheet, the plasticizer in the sheet may bleed over time and bleed between the sheet and the adhesive base material to cause poor adhesion.

It is an object of the present invention to provide a moisture-proof decorative sheet, a moisture-proof decorative board using the same, and a fitting such as a door, which does not warp due to the paper-reinforced paper whose moisture permeability and air permeability are adjusted to be low.

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 side of the paper-sheet-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 made by laminating inter-sheet strengthened paper 11 not having a printed pattern layer or the like interposed therebetween, and the moisture permeability can be adjusted by the thickness of the polyethylene layer. That is, when the thickness is 15 μm or less, the moisture permeability increases, and the effect of preventing warpage decreases. On the other hand, when the thickness is 50 μm or more, even if the thickness is further increased, the water vapor permeability does not change significantly, becomes saturated, 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 for protecting the surface of the printed pattern layer, such as acrylic urethane, polyester urethane, polyurethane, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer, and the like. The polyethylene layer which is the resin layer 12 is formed by extruding from a T-die with an extruder. The resin is not limited to polyethylene resin, but may be any resin having a moisture-proof effect such as polypropylene and polyvinylidene chloride. It can be selected as appropriate.

Although the moisture permeability can be adjusted to be low, it is preferably extruded and laminated to a thickness in the range of 15 to 50 μm.

In other words, printing paper having high moisture permeability is used as the sheet base material, but the moisture permeability can be adjusted by a moisture-proof resin such as a polyethylene resin and the extruded thickness of the resin. The resulting decorative sheet is obtained. Therefore, between the front surface side of the plate substrate and the paper-reinforced paper provided with a printed pattern layer and a protective resin layer on the front surface, and between the back surface side is provided the paper-reinforced paper via a synthetic resin layer such as polyethylene resin. A decorative sheet is stuck, and on the back side of this plate base material, a moisture-proof decorative sheet stuck to a back-side moisture-proof sheet in which an inter-sheet reinforced paper is stuck through a synthetic resin layer such as a polyethylene resin is humid, A fitting such as a decorative board or a flash door having an improved warpage preventing effect in which warping does not occur even under low humidity conditions can be obtained. Also, compared with the conventional warp prevention processing, the number of working steps is reduced, and various superiorities such as reduction of material cost and processing cost (metal support mounting cost, vinyl chloride sheet cost, laminating cost, etc.) can be reduced. It has the effect.
