CONSTITUTION:A pair of covering materials 1 are assembled respectively on both the surface and the rear of a wooden frame 7. Kraft paper 4 sides thereof are regulated to the surface sides. Japanese paper 8 is stuck on the surface of the kraft paper 4 of one side of covering material 1. A vinyl sheet 9 is stuck on the surface of the kraft paper 4 of the other side of covering material 1 by a water-soluble adhesive. Thin materials 3 made of polyethylene having moisture-unpermeable property are provided between the kraft paper 4 and cardboard 5 constituting the inside of a panel and between a veneer 6 and the wooden frame 7. Therefore moisture described below is not penetrated into the inside of the panel. This moisture is incorporated in an adhesive used in the case of sticking Japanese paper 8 or the vinyl sheet 9 on the surface of kraft paper 4. Therefore it is prevented that the cardboard 5, the veneer 6 and the wooden frame 7 of the inside of the panel incorporate water and are expanded and thereby fittings are warped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a covering material used for fittings, doors, partitions, display panels, ceiling materials, wall materials, furniture and the like, and a plate material using the same covering material.

[0002]

2. Description of the Related Art Conventionally, a plate material used for fittings or the like is a wooden frame material 21 formed in a plane rectangular ring shape as shown in FIG.
A veneer plate (single-plate three-layer structure) 22 is coated on both front and back surfaces of the above. Then, a pasting material 23 such as paper or vinyl sheet is pasted on the front surface and / or the back surface of the plate material, and fittings, doors,
It is used as an exhibition panel.

[0003]

However, in this conventional one, moisture such as an adhesive used when pasting paper, a vinyl sheet, etc. permeates inside the plate material and the frame material expands, so that the plate material is warped. There was a problem.

In particular, in recent years, fittings are often used as a partition between a Japanese-style room and a Western-style room. In this case, one side of the Japanese-style room is coated with Japanese paper and the other side of the Western-style room is covered with vinyl sheet. ing. In such fittings, the moisture on the vinyl sheet side is less likely to evaporate to the outside of the plate material than on the Japanese paper side, and the moisture moves to the plywood side and expands, while the water coated on the Japanese paper evaporates to the outside. Since it is easy to do so, the contraction on drying caused the balance on both sides to collapse and the plate material to warp easily.

[0005] Therefore, an object of the present invention is to provide a coating material and a plate material which are less likely to warp with moisture such as an adhesive used when other materials are stuck to the inside of the plate material.

[0006]

In order to achieve the above object, in the present invention, a hygroscopic thin material is laminated on the surface of a waterproof thin material, and a reinforcing material is provided on the back surface of the waterproof thin material. The main idea is to stack.

Further, the gist is that at least one surface of the frame material is coated with the coating material.

[0008]

In the present invention, since the waterproof thin material is provided between the hygroscopic thin material and the reinforcing material, the moisture on the hygroscopic thin material side does not soak into the reinforcing material side. . Therefore,
When it is used as a plate material, moisture on the side of the hygroscopic thin material permeates the inside of the plate material, and the frame material and the like that composes the inside of the plate material contains water and expands, so that the plate material does not warp.

Further, since the reinforcing plate is provided, it can sufficiently withstand the strength required as a plate material. Furthermore, since a hygroscopic thin material is provided, it is easy to use an adhesive when pasting another material to the plate material.

【Example】

(First Embodiment) Hereinafter, a covering material of a first embodiment of the present invention and a fitting as a plate material using the same covering material will be described.

As shown in FIG. 1, the covering material 1 is a thin aluminum material 2 (thickness: about 7 microns), and a polyethylene thin material 3 (thickness: 15 g micron) as a waterproof thin material on both front and back surfaces.
Are laminated by adhesion. Of these, Kraft 4 (36 g / m ² ) as a hygroscopic thin material is laminated on the surface of the polyethylene thin material 3 on the front surface side by adhesion, and on the back surface of the polyethylene thin material 3 on the back surface side. Cardboard 5 (375
g / m ² ) are laminated by adhesion, and a single plate 6 (thickness 0.7) as a reinforcing material is provided on the back surface of the cardboard 5.
5 mm veneer) is laminated by adhesion.

On the other hand, the frame member 7 is constructed by arranging a plurality of reinforcing bars vertically and horizontally inside a rectangular frame having a flat rectangular shape. The fitting of this embodiment is constructed by using a panel in which the front and back surfaces of the frame member 7 are coated with the coating material 1. That is, a pair of covering materials 1 are assembled on both front and back surfaces of a wooden frame member 7, and the kraft paper 4 side is the front surface side. Then, the Japanese paper 8 is attached to the surface of the kraft paper 4 of the one covering material 1, and the vinyl sheet 9 is attached to the surface of the kraft paper 4 of the other covering material 1 with a water-soluble adhesive,
An outer frame (not shown) is fitted to the frame member 7 of the panel to form a fitting.

In the fitting of the present embodiment, the polyethylene thin material 3 having the property of impervious to water is used as the kraft paper 4
Since it is provided between the cardboard 5, the single plate 6 and the frame member 7 which form the inside of the panel, the water content of the adhesive when the Japanese paper 8 or the vinyl sheet 9 is attached to the surface of the kraft paper 4 is Does not soak into the interior of the. Therefore, the cardboard 5, the single plate 6, the frame member 7 and the like inside the panel do not expand due to the inclusion of water, and the fitting does not warp. In particular, inside the fitting on the side where the vinyl sheet 9 is attached, since the vinyl sheet 9 does not allow water to easily pass through, there is a problem that water easily permeates into the fitting as much as it is difficult for water to evaporate to the outside. Then, the polyethylene thin material 3 can prevent water from seeping into the fitting.

Further, since the single plate 6 is provided, the strength required for a fitting is sufficiently satisfied. Further, since the hygroscopic kraft paper 4 is provided, it is easy to use a water-soluble adhesive when the Japanese paper 8 or the vinyl sheet 9 is attached.

Further, since the covering material 1 is composed of the aluminum thin material 2, the polyethylene thin material 3, the kraft paper, the cardboard 5 and the single plate 6, it is very lightweight. Specifically, the conventional product using a veneer plate as the covering material is 4110.
g / m ² , whereas the product of this example is 3490 g /
m ² . Therefore, it is possible to easily move the fitting when it is moved on the threshold.

Furthermore, since the thin aluminum material 2 is provided, a soundproof effect and a flameproof effect can be expected. Note that it is also possible to embody a folding partition by connecting a plurality of Japanese paper or the like having the Japanese paper and the like attached to both sides in the lateral direction of the fitting using the covering material of the present embodiment. In this case, since it is very light, the burden on the upper part for suspending the partition is small.

Further, a fitting using the covering material of the present embodiment, which has wood grain boards or the like on both front and back surfaces, can be used for an open door. In this case, since it is very light, the hinge supporting the door is not overloaded and the building is not deteriorated. (Second Embodiment) Next, the second embodiment will be described with reference to FIG. The same components as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, in the construction of the fitting as the plate material of the above-mentioned embodiment, one side surface is formed by a poly plywood (polyvinyl chloride plywood or processed plywood) 10 and the other side surface is the same covering material 1 as in the above-mentioned embodiment. The place formed by is different. In addition, in this embodiment, one side surface is formed of the poly plywood 10, but it may be formed of the "pull" green plywood. In this embodiment, the frame member 7 of the fitting is constructed by horizontally arranging a plurality of reinforcing bars laterally at a predetermined interval inside a planar rectangular ring-shaped frame.

The fitting as the plate material in this embodiment is a product in which a vinyl sheet 9 (or Japanese paper 8 may be used) is attached using a water-soluble adhesive and dried. In this example, the warp that occurred after drying was only about 3 mm in the vertical length direction of the fitting. The warp of 3 mm is a value within an allowable range that can withstand actual use and can be used as a product.

On the other hand, as a comparative example, a vinyl sheet 9 (or Washi paper 8 may be used) is similarly attached to a fitting having both sides formed with polyplywood by using a water-soluble adhesive. In this comparative example, the warp that occurred after drying was about 7 mm in the vertical length direction of the fitting. This 7mm
The warp was not practical as a fitting.

(Third Embodiment) Next, a display panel as a plate material using the covering material of the first embodiment will be described.

In the display panel of this embodiment, the coating material 1 of the first embodiment is coated only on the front surface side of the flat rectangular frame member, and linen cloth is attached to the surface thereof. A hanging metal fitting is attached to the upper end of the frame member, and when used, the display panel is hung from the ceiling by the hanging metal fitting to fix an exhibit on the surface of the panel. .

When the panel of this embodiment is used, the polyethylene thin material 3 having a property of imperviousness of water is provided between the kraft paper 4 and the cardboard 5, the single plate 6 and the frame material constituting the inside of the panel. Since it is provided, the moisture of the adhesive does not soak into the inside of the panel when the linen is pasted on the surface of the kraft paper 4, and the panel does not warp. Also, because it is very light, you can easily carry in, carry out, and suspend panels at the exhibition hall. Furthermore, by changing the thickness of the frame material 7,
