BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a painted decorative plate used as a surface material for doors, furniture, etc. in the field of building materials, and in particular, by imparting flexibility to the resin to be coated, the interior of a house The present invention relates to a coated decorative plate that can be used as a member for a vehicle.

[0002]

2. Description of the Related Art Conventionally, a decorative sheet with a pattern printed on a base material and a resin coated on the surface of the decorative sheet has been widely used as a surface material for doors and furniture. And is known. The material of the decorative paper used at this time is
Usually, it is a thin paper, and the surface is coated with a thick urethane resin paint or the like. For this reason, when the existing coated decorative board is subjected to V-cut processing, for example, the hard urethane paint and the decorative paper that have been painted cannot follow the tension, and the decorative paper is broken and the V-cut processing occurs. Could not be done.

However, the coated decorative board is inexpensive in price, and since it is coated with a thick resin coating, it is excellent in design, but it can be used as a decorative member for interior decoration of a house. However, the range of use was limited to face materials (doors, etc.). Further, a decorative board using a vinyl chloride resin that is usually used for V-cut processing is very excellent in processability, but the vinyl chloride resin is expensive in cost.
Since it is not suitable for incineration at the time of disposal, it was necessary to change to another material.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a coated decorative board which enables V-cut processing and can be applied to a structural member for a house interior and can be manufactured at low cost. To do.

[0005]

In order to achieve the above object, a decorative paper (12) obtained by applying a pattern printing layer (b) to an inter-paper reinforcing base paper (a) on a base material (11) such as plywood. Is attached, and a resin decorative layer (15) is provided thereon, and the resin layer (15) is flexible.

[0006] Further, the reinforced base paper (a) has a basis weight of 1
It is characterized in that it is made of a resin mixed paper of 0 to 100 g / m ² .

The reinforced base paper (a) has a basis weight of 1
It is characterized in that it is made of resin impregnated paper of 0 to 100 g / m ² .

Further, the reinforced base paper (a) has a basis weight of 1
It is characterized in that it is made of synthetic fiber paper made from 0 to 100 g / m ² of synthetic fiber.

Further, the resin layer (15) on the decorative paper (12) is characterized by being made of a soft urethane resin.

The present invention will be described in detail. As shown in FIG. 1, the coated decorative board of the present invention comprises a decorative paper (12) in which a pattern printing layer (b) is provided on a base paper (a) having a strengthened space, and a base material such as plywood or fiber board. A coated decorative board (10), which is attached to (11) and on which a resin layer (15) is provided, wherein a flexible resin is used for this resin layer. Also,
Since the inter-paper reinforced base paper (a) is made of resin-blended paper, resin-impregnated paper, or synthetic fiber paper containing fibers whose main component is synthetic resin, strength against tearing and tension is imparted. Even if V-cut processing is performed and it is bent,
There is no problem with the decorative paper or resin layer.

That is, by making the inter-paper reinforced base paper (a) a resin-mixed paper, strength against tearing at the time of V-cut processing is imparted, and by making the base paper (a) a resin-impregnated paper, tearing is prevented. Since the strength and the followability to the tension of the decorative paper are imparted, for example, the resin to be impregnated may contain latexes containing a nitrile rubber as a main component. Further, when the base paper (a) is made of synthetic fiber paper made from fibers having a synthetic resin as a main component, strength against tearing and followability to tension are imparted. For example, the synthetic fiber used for papermaking of the base paper (a) may be a fiber containing polyethylene terephthalate resin as a main component.

Further, by making the resin coating material used for the resin layer (15) highly flexible, followability to tension is imparted. For example, soft urethane resin facilitates V-cut processing. For example, polyester-modified acrylic polyol, polyether polyols, etc. can be used, and elastomer type blends are also possible.

[0013]

In the coated decorative board of the present invention, the inter-paper reinforcing base paper (a) in the decorative paper (12) is made of resin-blended paper, resin-impregnated paper, or synthetic fiber paper made from synthetic resin-based fibers. By doing so, the strength against tearing and the followability to the tension are imparted, and the flexibility to the resin coating used for coating the resin layer (15) imparts the followability to the tension. Therefore, in both cases, V-cut processing suitability can be obtained.

[0014]

EXAMPLES Examples will be described in detail below. As shown in FIG. 1, the substrate (11) may be any medium that can be subjected to V-cut processing such as medium density fiberboard (MDF) and wood-based plywood. Further, as the base paper (a) in which the distance between the decorative papers (12) is strengthened, the basis weight is 30 to 100 g / m 2.
^{About 2} is good, and this base paper is made of resin mixed paper, resin-impregnated paper in which base paper is impregnated with a latex emulsion containing nitrile, or synthetic fiber paper made from synthetic fibers (for example, polyethylene terephthalate), or non-woven fabric. be able to. That is, since strength against tearing and tension in V-cut processing is required, it is preferable to use the above-mentioned inter-paper reinforcing base paper as the decorative paper.

A pattern printing layer (b) such as a wood grain pattern, an abstract pattern, or a conduit is provided on one surface of the base paper (a) having a reinforced paper interval,
This is a decorative paper (12). As the printing ink, a nitrocellulose-based ink is preferable, and printing by a gravure printing method is suitable for forming the pattern printing layer, although not limited thereto.

As the adhesive used for sticking the decorative paper (12) to the base material (11), vinyl acetate emulsion was used in this embodiment, but the adhesive is not particularly limited. Further, as a sticking method, a known method such as roll milanate can be used.

Next, a resin paint is applied onto the decorative paper attached to the base material, and a resin having high flexibility is preferable, and a soft urethane resin or the like is preferable. The coating method, natural roll coating, reverse roll coating, may by flow coating or the like known method, also, the coating amount may be in the range of 6-10 g / scale ^2.

<Example 1> A resin-mixed paper having a basis weight of 30 g / m ² was coated with a wood grain pattern print layer by a gravure printing method using a printing ink containing nitrocellulose as a main component. I used paper. This decorative paper was attached to a base material made of a medium-density fiber board (MDF) having a thickness of 4 mm by roll lamination via a vinyl acetate emulsion adhesive. Further, a coating material made of a soft urethane resin was applied on the attached decorative paper by a flow coating method to a thickness of 10 g / square ² and dried to obtain a coated decorative board.

The base material portion of the obtained coated decorative plate was subjected to V-cut processing to form a door member bent at 90 degrees on the base material side. The decorative paper and the resin coating film on the bent surface portion were not broken or cracked.

<Example 2> A base paper having a basis weight of 75 g / m ² was impregnated with a latex emulsion containing a nitrile, resin-impregnated paper was used, and a printing ink containing nitrocellulose as a main component was used to make an abstraction by a gravure printing method. The pattern was printed to make a decorative paper. Otherwise, a coated decorative board was obtained by the same production method as in Example 1.

The base material portion of the obtained coated decorative board was subjected to V-cut processing and bent at 90 degrees to obtain a furniture member. As with Example 1, the decorative paper and the resin coating film on the bent surface portion did not break or crack.

<Example 3> A fiber having a polyethylene terephthalate resin as a main component was made into paper, and the basis weight was 30 g / m ^2.
The base paper made of the synthetic resin fiber paper was used to print a wood grain conduit pattern by a gravure printing method with a printing ink containing nitrocellulose as a main component to obtain a decorative paper. Otherwise, a coated decorative board was obtained by the same production method as in Example 1.

The base material portion of the obtained coated decorative plate was subjected to V-cut processing and bent at 90 degrees to obtain a wall member for interior. As with Example 1, the decorative paper and the resin coating film on the bent surface portion did not break or crack.

[0024]

Since the present invention has the above-mentioned constitution, it has the following effects. That is, V-cut processing, which is not possible with a coated decorative board using normal paper for decorative paper, can be performed, and the decorative paper and the coating resin do not break or crack. Further, since the price of the decorative material is low, the V-cut work material can be provided at a lower cost than when vinyl chloride is used. Further, conventionally, when a coated decorative board is used for the face material, it took time to produce the same design feeling due to the difference in the material, but according to the coated decorative paper board of the present invention, the same decorative design material is used. Can be provided, and the appearance can be made uniform. Further, the coated decorative plate can be thickly coated by flow coating or the like, and has an excellent effect such as obtaining a high-class appearance.
