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 which is provided with a desired cloth attached to the surface of an original plate for decoration.

[0002]

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

[0003] In response to this demand, a desired cloth is stuck on the surface of a decorative board of furniture to satisfy the above-mentioned demand. However, when a cloth composed of relatively thick yarn is applied with a coarse cloth, such a cloth has a problem such as fraying of the cloth at a cut portion at an end of a decorative plate.

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

[0005]

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

[0006] Many of the dyes and pigments currently used when used for furniture and the like (so-called durable consumer goods) have a problem due to poor light fastness. Therefore, the color tone is limited to a dull color tone having good light fastness, and a colorful bright color tone (except for a very small portion of the color tone) is extremely difficult at the present time in terms of light fastness.

SUMMARY OF THE INVENTION The present invention solves the problem of fraying of a decorative board, in which a desired cloth is stuck on the surface of an original plate to decorate even if the cloth is stuck to the side of the decorative board. It is an object of the present invention to provide a decorative board for furniture in which the color tone of the cloth is not impaired even when used for a long period of time and a method for producing the same.

[0008]

In the decorative veneer for furniture according to the present invention, a veneer base plate and a cloth are impregnated or coated with a resin in advance.
Fabric composite from the plane of the decorative plate source plate - resin created Te
A resin-impregnated cloth layer adhered over a required side surface, a light-resistant resin intermediate layer containing an ultraviolet absorber or an ultraviolet reflector formed on the resin-impregnated cloth layer; A cured resin layer formed on the coating layer , wherein the resin-impregnated cloth layer
Is composed of a dyed or printed cloth, and the cured resin layer
Is an ultraviolet curable resin .

In the method for producing a decorative board for furniture according to the present invention, a step of impregnating or applying a thermosetting resin or a thermoplastic resin to a dyed or printed cloth to form a resin-cloth composite is provided. The resin-cloth composite is placed on a flat surface of a decorative veneer plate.
Forming a resin-impregnated cloth layer by adhering or thermocompressing over a necessary side surface, and applying a resin containing an ultraviolet absorber or an ultraviolet reflector on the resin-impregnated cloth layer to obtain light resistance. And a step of applying a cured resin layer made of an ultraviolet curable resin on the light-resistant resin intermediate coat layer.

[0010]

[0011]

In the present invention, since the desired cloth itself is impregnated with a resin to form a resin-impregnated cloth layer, the cloth adhered to the base plate of the decorative board, particularly, the cloth up to the side surface of the decorative board. Even if it is stuck, there is no fraying of the cut part of the cloth. Also,
Since it is provided with a light-resistant resin intermediate coating layer containing an ultraviolet absorber or an ultraviolet reflective agent formed on the resin-impregnated cloth layer, and a cured resin layer formed on the light-resistant resin intermediate coating layer. UV light hardly reaches the surface of the cloth, changes in color tone due to UV light are hindered, and it can be cut off sufficiently for long-term use. , And a color tone that is in balance with surrounding articles such as electric appliances can be obtained.

Further, in the present invention, a step of impregnating a desired cloth with a thermosetting resin or a thermoplastic resin to form a resin-cloth composite; And a step of forming a resin-impregnated cloth layer layer by adhering on the upper layer, so that the cut portion of the cloth is not frayed even with the cloth before being bonded. In addition, this is performed by a step of forming a resin-cloth composite by applying a thermoplastic resin, and a step of forming a resin-impregnated cloth layer layer by thermocompression bonding the resin-cloth composite on the surface of a decorative plate original plate. Also, there is no fraying at the cut portion, and the resin which has been softened by heat at the same time as sticking enters between the fibers of the cloth, and has the same effect.

[0013] 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 coat layer, and setting a cured resin on the light-resistant resin intermediate coat layer Forming a layer that inhibits a change in color tone due to ultraviolet light.

In the present invention, a desired cloth is impregnated with or coated with a thermosetting resin or a thermoplastic resin.
To prepare a cloth composite, to bond or thermocompression-bond the resin-cloth composite on the surface of the decorative veneer plate to form a resin-impregnated cloth layer,
There is no fraying at the cut portion of the cloth, and the cut of the desired cloth may be cut into a predetermined shape before sticking, or may be cut after sticking according to the shape of the sticking portion. The viscosity at the time of impregnation or application is adjusted to such an extent that when impregnated or applied, the resin penetrates to form a resin-cloth composite. 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 ultraviolet absorber or the ultraviolet reflector has a long light resistance life, has good compatibility with a resin, does not change its color resistance, and does not impair the color tone of the cloth to which it is adhered. Are variously selected and used. Further, as the resin containing the ultraviolet absorber or the ultraviolet reflector, polyurethane, polyester resin or an acrylic resin similar thereto can be used. A mixture of these may be used, if necessary.
This is repeated at least twice to form a light-resistant resin intermediate coating layer. Specific examples of the ultraviolet absorber include benzophenone-based, triazole-based, and benzoate-based ones, and titanium dioxide and the like can be used as the ultraviolet reflector.

A cured resin layer is applied on the intermediate layer of the light-resistant resin to finish it. By using an ultraviolet-curable resin which is cured by ultraviolet rays, the cured resin layer has high heat resistance and chemical resistance. A certain resin plate can be formed on the surface of the board. Further, as the ultraviolet curing resin, an unsaturated polyester resin can be used.

1 is a partially cutaway perspective view showing the structure of an embodiment of a decorative board according to the present invention. In the figure, from the front side (5) of the base plate (1) with rounded edges,
A resin-impregnated cloth layer (2) is adhered over (6). Further, on the resin-impregnated cloth layer (2), there is formed a light-resistant resin intermediate coating layer (3) containing an ultraviolet absorber or an ultraviolet reflecting agent, and on this light-resistant resin intermediate coating layer (3), A cured resin layer (4) is formed. This decorative board was prepared as follows.

Example 1 First, a cloth (2) to be adhered to a base plate (1) was immersed and dried (baked) in an aqueous solution of a melamine-based thermosetting resin (emulsion type). This prevents fraying of the cut portion of the cloth. The melamine-based thermosetting resin is used because it has a large effect of preventing fraying, has little discoloration, and is relatively inexpensive. Note that an acrylic resin may be used instead of the melamine resin.

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 a necessary portion (surface) of the original plate (1) where the cloth was to be attached, and the cloth was adhered to the flat surface and the necessary side surfaces of the original plate. In the case of sticking without cutting as described above, cutting may be performed according to a required shape after sticking.

Next, a polyurethane resin mixed with 0.5% to 2.5% of a benzophenone-based ultraviolet absorber is applied to the surface of the cloth. The intermediate coating was repeated twice or more as necessary. Further, an unsaturated polyester-based UV-curable resin was applied to the intermediate-coated cloth surface to finish it.

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

The required shape of the original plate including the side surface (6)
The cloth is cut, a vinyl acetate (emulsion) adhesive is applied to the part (surface) of the original plate (1) where the cloth needs to be adhered, and the cloth is cut with a curved vacuum press (manufactured by Save Co., Ltd.). Affixed to the flat surface of the original plate and the required side surfaces In the case of sticking without cutting as described above, cutting may be performed according to a required shape after sticking.

Next, a polyurethane resin mixed with 0.5% to 2.5% of a benzophenone-based ultraviolet absorber is applied to the surface of the cloth. The intermediate coating was repeated twice or more as necessary. Further, an unsaturated polyester-based UV-curable resin was applied to the intermediate-coated cloth surface to finish it.

[0024]

As described above, the present invention forms a resin-impregnated cloth layer by impregnating a desired cloth itself with a resin. Even if the cloth is stuck to the side, there is no fraying of the cut part of the cloth. 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 is provided with the cured resin layer formed on the light-resistant resin intermediate coating layer, the ultraviolet rays hardly reach the surface of the cloth, the change in the color tone due to the ultraviolet rays is inhibited, and the use for a long time can be sufficiently stopped. This makes it possible to use brightly dyed or printed fabrics, which were normally unusable, and to obtain a color tone that is in proportion to surrounding articles such as electric appliances.

In the method of the present invention, a resin-cloth composite is prepared by impregnating a desired cloth with a thermosetting resin or a thermoplastic resin; And a step of forming a resin-impregnated cloth layer by adhering on the upper layer, so that even if the cloth is not yet pasted, there is an effect that the cut portion of the cloth is not frayed.
