Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative veneer for furniture in which a desired cloth is attached to the surface of an original plate for decoration.

[0002]

2. Description of the Related Art In recent years, due to the diversification of life, the following demands have been made for furniture, which has become an important point of products. Provide a deeper, warmer appearance with a more luxurious feel Provided with a color tone that is more colorful and matches the surrounding items such as electric appliances

On the other hand, a desired cloth is attached to the surface of a decorative plate of furniture to meet the above-mentioned demand. However, when a cloth composed of relatively thick threads and having a coarse texture is stuck, such cloth causes problems such as fraying of the cloth at the cut portion at the end of the decorative plate.

As a countermeasure against this, a method has been proposed in which a cloth is fixed to a decorative plate original plate with a resin or the like, and after this is cured, it is cut into the shape of the original plate (Japanese Utility Model Publication No. 2-46753).

[0005]

However, in general, the side surface of the decorative board is often located in front of the furniture, and in the above-mentioned method, the dyed or printed cloth is not attached to the side surface of the decorative board. The value could not be fully utilized for the entire furniture.

Further, most of the dyes and pigments currently used, when used for furniture or the like (so-called durable consumer goods), often cause a problem due to poor light fastness. Therefore, it is limited to a dull color tone with good light resistance, and a colorful bright color tone (excluding a very small portion of the color tone) is extremely difficult at this point in terms of light resistance.

The present invention solves the problem of fraying of the cloth even if the cloth is stuck even to the side surface of the decorative plate, in which the desired cloth is adhered to the surface of the original plate for decoration. An object of the present invention is to obtain a decorative panel for furniture which does not impair the color tone of the cloth even if it is used for a long period of time and a method for producing the same.

[0008]

In the decorative decorative board for furniture according to the present invention, a decorative board original plate, a resin-impregnated cloth layer adhered to the surface of the decorative board original plate, and a resin-impregnated cloth layer are formed on the decorative board original plate. And a cured resin layer formed on the light-resistant resin intermediate coating layer.

In the method for manufacturing a decorative veneer for furniture according to the present invention, a step of impregnating or coating a desired cloth with a thermosetting resin or a thermoplastic resin to prepare a resin-cloth composite,
A step of pasting the resin-cloth composite on the surface of the decorative plate original plate, or forming a resin-impregnated cloth layer layer by thermocompression bonding, and containing an ultraviolet absorber or an ultraviolet reflector on the resin-impregnated cloth layer And a step of forming a light-resistant resin intermediate coating layer to form a light-resistant resin intermediate coating layer, and a step of applying a cured resin layer on the light-resistant resin intermediate coating layer.

Further, specifically, it is disclosed that the resin-impregnated cloth layer is made of dyed or printed cloth, and the cured resin layer is an ultraviolet curable resin.

[0011]

In the present invention, since the desired cloth itself is impregnated with the resin to form the resin-impregnated cloth layer, the cloth after being attached to the decorative board original plate, particularly the cloth even on the side surface of the decorative board, is formed. Even if it is attached, the cut part of the cloth does not fray. Also,
Since a light-resistant resin intermediate coating layer containing an ultraviolet absorber or an ultraviolet reflector formed on the resin-impregnated cloth layer and a cured resin layer formed on the light-resistant resin intermediate coating layer are provided. , It is difficult for UV rays to reach the surface of the cloth, the change in color tone due to UV rays is blocked, and it can be sufficiently extinguished even for long-term use. It is possible to use brightly dyed or printed cloth that was not normally available. Thus, a color tone that balances with surrounding articles such as electric appliances can be obtained.

Further, in the invention of this method, a step of impregnating a desired cloth with a thermosetting resin or a thermoplastic resin to prepare a resin-cloth composite, and the resin-cloth composite on the surface of a decorative sheet base plate. Since it has a step of forming a resin-impregnated cloth layer layer by sticking it on the top, even if the cloth is not stuck, the cut portion of the cloth does not fray. In addition, this includes a step of forming a resin-cloth composite by applying a thermoplastic resin, and a step of forming the resin-impregnated cloth layer layer by thermocompression-bonding the resin-cloth composite on the surface of the decorative sheet master plate. However, there is no fraying at the cutting portion, and the resin softened by heat at the same time as the attachment enters between the fibers of the cloth and brings about the same effect.

Further, a step of applying a resin containing an ultraviolet absorber or an ultraviolet reflector on the resin-impregnated cloth layer to form a light-resistant resin intermediate coating layer, and a cured resin on the light-resistant resin intermediate coating layer. Since it has a step of applying a layer, a layer that inhibits a change in color tone due to ultraviolet rays is formed.

In the present invention, a desired cloth is impregnated with or coated with a thermosetting resin or a thermoplastic resin to form a resin.
To make a cloth composite, and to adhere or thermocompress the resin-cloth composite on the surface of the decorative plate original plate to form a resin-impregnated cloth layer,
There is no fray at the cut portion of the cloth, and the desired cloth may be cut into a predetermined shape before sticking, or may be cut according to the shape of the sticking portion after sticking. The viscosity at the time of impregnation or application is adjusted to such an extent that the resin-cloth composite can be formed by bleeding when impregnated or applied. Further, as a specific thermosetting resin, a melamine resin or an acrylic ester resin can be used, and as a thermoplastic resin, a polyester resin or an acrylic resin can be used.

The above-mentioned ultraviolet absorber or ultraviolet reflector has a long light resistance life, good compatibility with a resin, does not change its color resistance itself, and does not impair the color tone of the attached cloth. Are selected and used. Further, as the resin containing the ultraviolet absorber or the ultraviolet reflector, polyurethane, polyester resin or acrylic resin similar thereto can be used. If necessary, mix these two
This is repeated more than once to form the light-resistant resin intermediate coating layer. Specific examples of UV absorbers include benzophenone-based, triazole-based, and benzoate-based ones, and ultraviolet reflectors include titanium oxide and the like.

A cured resin layer is applied onto the light-resistant resin intermediate coating layer for finishing. By using an ultraviolet curable resin which is cured by ultraviolet rays in the cured resin layer, high hardness heat resistance and chemical resistance can be obtained. A resin plate can be formed on the surface of the board. An unsaturated polyester resin can be used as the ultraviolet curable resin.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially cutaway perspective view showing the construction of an embodiment of a decorative board according to the present invention. In the figure, from the front surface (5) to the side surface of the decorative plate original plate (1) with rounded edges
The resin-impregnated cloth layer (2) is attached over (6). Furthermore, a light-resistant resin intermediate coating layer (3) containing an ultraviolet absorber or an ultraviolet-reflecting agent is formed on the resin-impregnated cloth layer (2). A cured resin layer (4) is formed. This decorative board was prepared as follows.

Example 1 First, the cloth (2) to be attached to the decorative board original plate (1) was dipped and dried (baked) in an aqueous solution of a melamine thermosetting resin (emulsion type). This prevents fraying of the cut portion of the cloth. The reason why the melamine thermosetting resin is used is that it has a large effect of preventing fraying, little discoloration, and is relatively inexpensive. Note that an acrylic resin may be used instead of the melamine resin.

[2] to the required shape of the original plate including the side surface (6)
The cloth was cut, and a vinyl acetate-based adhesive was applied to the area (surface) of the original plate (1) where the application of the cloth was necessary, and the cloth was attached to the flat surface and necessary side surfaces of the original plate. In the case of sticking without the above cutting, it may be cut according to the required shape after sticking.

Then, a polyurethane resin containing 0.5% to 2.5% of a benzophenone type ultraviolet absorber is applied to the surface of the cloth. The intermediate coating was repeated twice or more as needed. Further, an unsaturated polyester-based UV curable resin was applied to the surface of the intermediate coating to finish.

Example 2 First, the cloth (2) to be attached to the decorative board original plate (1) was coated with a polyacrylic resin on the back surface (or surface) of the cloth. This prevents fraying of the cut portion of the cloth.

[2] to the required shape of the original plate including the side surface (6)
Cut the cloth, apply vinyl acetate (emulsion) adhesive to the area (surface) of the original plate (1) where the cloth needs to be attached, and use a curved surface vacuum press (made by SAVE Co., Ltd.) to cut the cloth. It was attached to the flat surface and the necessary side surface of the original plate. In the case of sticking without cutting as described above, it may be cut according to the required shape after sticking.

Then, a polyurethane resin containing 0.5% to 2.5% of a benzophenone type ultraviolet absorber is applied to the surface of the cloth. The intermediate coating was repeated twice or more as needed. Further, an unsaturated polyester-based UV-curing resin was applied to the surface of the above-mentioned intermediate coating to finish.

[0024]

As described above, according to the present invention, a desired cloth itself is impregnated with a resin to form a resin-impregnated cloth layer. Even if the cloth is attached even to the side, the cut portion of the cloth does not fray. Further, a light resistant resin intermediate coating layer containing an ultraviolet absorber or an ultraviolet reflector formed on the resin-impregnated cloth layer,
Since it has a cured resin layer formed on this light-resistant resin intermediate coating layer, it is difficult for ultraviolet rays to reach the cloth surface, the change in color tone due to ultraviolet rays is blocked, and it is sufficiently extinct even for long-term use. Thus, it is possible to use a brightly dyed or printed cloth which has not been normally usable, and to obtain a color tone that matches with surrounding articles such as electric appliances.

Further, in the invention of this method, a step of impregnating a desired cloth with a thermosetting resin or a thermoplastic resin to prepare a resin-cloth composite, and the resin-cloth composite on the surface of a decorative sheet base plate. Since it has a step of forming a resin-impregnated cloth layer layer by attaching the cloth on the upper side, there is an effect that the cut portion of the cloth is not frayed even with the cloth before being adhered.
