Description

The present invention relates to a veneer sheet, which is a decorative tool using a veneer, a clothing accessory using the veneer sheet, and furniture.

Conventionally, thin veneers peeled off from natural wood have been used for furniture such as shelves. Further, since the texture of natural wood possessed by the veneer is excellent as a design, it is also in demand as a design aspect of clothing accessories such as bags.

However, since the veneer is made of wood, it is difficult to bend it, so it is generally used for flat top plates and surfaces, and not for corners or curved parts. Further, for the same reason as described above, the veneer is structurally incompatible with clothing accessories that are supposed to be deformed during use, although it is in demand.

The present invention has been proposed in view of such circumstances. That is, it is an object of the present invention to provide veneer sheets, clothing accessories and furniture that can be used for curved parts or parts that are supposed to be curved.

In order to achieve the above object, the veneer sheet according to the present invention comprises a veneer layer in which a veneer is attached to a backing material of a non-woven fabric via an adhesive, and a coating layer applied to the surface of the veneer layer. It is characterized in that the coating layer is composed of an undercoat layer made of a polyurethane resin coating material and a topcoat layer made of a polyurethane resin coating material having a composition different from that of the undercoating layer.

The veneer sheet according to the present invention is characterized in that the veneer layer is colored.

The veneer sheet according to the present invention is characterized by having a leather layer and the veneer layer bonded to the surface of the leather layer with an adhesive.

The veneer sheet according to the present invention is characterized by having a veneer layer and the veneer layer bonded to the surface of the base layer with an adhesive.

The clothing accessory according to the present invention is characterized by having a veneer sheet on the design surface.

The furniture according to the present invention is characterized by having a veneer sheet on the surface.

The veneer sheet according to the present invention has a veneer layer in which a veneer is attached to a backing material of a non-woven fabric via an adhesive, and a coating layer applied to the surface of the veneer layer, and the coating layer is a polyurethane resin. It is composed of an undercoat layer composed of a paint and a topcoat layer composed of a polyurethane resin paint having a composition different from that of the undercoat layer. That is, since the coating layer impregnates the veneer layer and protects the veneer layer, it will not be damaged even if the veneer layer is curved, and the coating layer will not be cracked or the like. Therefore, the veneer sheet can be used for a curved portion or a portion that is supposed to be curved. In addition, the undercoat layer suppresses fluff on the surface of the veneer layer, and the topcoat layer realizes a smooth feel.

In the veneer sheet according to the present invention, the veneer layer is colored. Therefore, the veneer sheet can be appropriately adapted according to the environment and the situation.

The veneer sheet according to the present invention has a leather layer and a veneer layer bonded to the surface of the leather layer with an adhesive. Therefore, for example, various objects such as clothing accessories and furniture can be given the texture of natural wood by veneer.

The veneer sheet according to the present invention has a veneer layer and a veneer layer bonded to the surface of the base layer with an adhesive. Therefore, for example, various objects such as clothing accessories and furniture can be given the texture of natural wood by veneer. Further, since the base layer is sufficiently soft for sewing, cracks and the like do not occur.

The clothing accessory according to the present invention has a veneer sheet on the design surface. Therefore, bags, shoes, slippers, belts, photo frames, accessories, etc., which have the texture of natural wood with veneer, are realized.

The furniture according to the present invention has a veneer sheet on the surface. Therefore, a bed, a chest of drawers, a dresser, a desk, a chair, etc., which has the texture of natural wood with veneer, is realized.

FIG. 1 is a perspective view showing a veneer sheet according to an embodiment of the present invention. FIG. 2 is a schematic view of a clothing accessory having a veneer sheet according to an embodiment of the present invention. FIG. 3 is a schematic view of furniture having a veneer sheet according to an embodiment of the present invention.

The veneer sheet according to the embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the veneer sheet 1 according to the present embodiment. The actual thickness of the veneer sheet 1 is about 1 mm, but in FIG. 1, the thickness is exaggerated in order to promote understanding of the device.

As shown in FIG. 1, the veneer sheet 1 is applied to the leather layer 2, the surface of the leather layer 2, the veneer layer 3 bonded to the surface of the leather layer 2 with an adhesive, and the surface of the veneer layer 3. It also has a coating layer 6. The leather layer 2 is natural leather, for example, cow, sheep, pig or the like. The leather layer 2 may be artificial leather, synthetic leather, or the like. The veneer layer 3 is formed by bonding the veneer 5 to the backing material 4 of the non-woven fabric via an adhesive. The veneer 5 is, for example, a thinly peeled softwood or hardwood, and has a thickness of 0.17 mm or more and 0.40 mm or less. Conifers are, for example, pine, sugi, cypress and the like, and hardwoods are, for example, oak, octopus, hippopotamus, zelkova, oak, chiku, maple and the like.

Here, it is also possible to replace the leather layer 2 with a base layer. The base layer is, for example, a slicer or the like, and is made of a non-woven fabric, nylon, polyester or the like.

The coating layer 6 is composed of an undercoat layer 7 made of a polyurethane resin paint and a topcoat layer 8 made of a polyurethane resin paint having a composition different from that of the undercoat layer 7. The polyurethane resin coating material is a two-component type using normal butyl acetate or the like as a main raw material, and the main agent and the curing agent are mixed and appropriately diluted with a diluent such as thinner. The polyurethane resin paint contains an anti-UV component that prevents deterioration due to ultraviolet rays. Antibacterial and sterilizing components such as silver ions may be contained as appropriate. The composition of the undercoat layer 7 and the topcoat layer 8 is as follows.
<Undercoat layer 7>
Main agent: Hardener: Diluted solution (thinner) = 100: 50: 100
<Topcoat layer 8>
Main agent: Hardener: Diluted solution (thinner) = 100: 25: 40

Here, the manufacturing process of the veneer sheet 1 will be described. The manufacturing process includes a wood trimming process, a boiling process, a thrusting process, a slab material pretreatment process, a backing material preparation process, a heat pressure bonding process, a polishing finish process, a product peeling process, a leather layer bonding process, and a surface coating process. After the product peeling step and before the surface coating step, a coloring step is appropriately performed.

<Wood removal process>
In the wood-cutting process, wood is cut from the cut down logs (logs) to make a processing material with a shape suitable for thrusting.

<Boil process>
In the boiling process, the processed material is put into a boiling tank and boiled for a long time. This process makes it easier to cut the processed material thinly in the subsequent thrusting process. The boiling process lasts from 60 hours to 80 days, during which the hot water temperature is gradually increased. The number of days required for the boiling process and the final upper temperature limit vary depending on the tree species and the condition of the raw wood. For example, when the log is ebony, the time required for the boiling process is 60 days. The initial temperature (water temperature) is about 4 degrees of cold water temperature, and it is raised by about 1 degree per day, and by 3 days before the final day, which is the period immediately before taking out, it is in the mid 50 degrees range (processing). The appropriate temperature is selected according to the condition of the material). For three days until the final day, the ebony is boiled at a hot water temperature of 60 degrees, which is the upper limit. On the other hand, when the log is hard maple, the time required for the boiling process is 3 days. The temperature on the first day is 20 to 32 degrees, the temperature on the second day is 33 to 38 degrees, and the temperature on the third day is 39 to 55 degrees (55 degrees is the upper limit temperature of the hot water for boiling hard maple).

<Pushing process>
In the veneer process, the processed material that has undergone the boiling process is cut by a cutting machine such as a rotor slicer or a vertical veneer or horizontal veneer slicer according to the application of the veneer sheet 1, and a thin veneer material is obtained. The thickness of the veneer material is 0.17 mm or more and 0.30 mm or less. If it is within 0.40 mm, it is suitable for a portion having a large degree of curvature.

<Veneer material pretreatment process>
In the veneer material pretreatment step, the veneer material is suspended in a drying chamber within 30 minutes, and quick drying is performed in which about 70% of the contained water is evaporated by the radiant heat of the heater. For example, the temperature of the drying chamber is about 38 degrees. Allow it to dry naturally in an indoor environment while hanging for about a day. After that, the veneer material is placed in a stacked state and cured for several tens of days. The quick drying is preferably within 1 hour at the longest. In the veneer material pretreatment process, the veneer material shrinks from a dozen percent to a dozen percent, but does not harden in the shrunk state, and is elastic and extremely durable. As a heater, a dielectric heater using microwaves is not suitable.

<Backing material preparation process>
In the backing material preparation step, the backing material 4 is attached on the base plate. More specifically, the adhesive is applied on the base plate to which the release paper is attached, the backing material 4 is attached onto the base plate, and the adhesive is applied to the upper surface of the backing material 4. The backing material 4 is, for example, a non-woven fabric or paper, and if it is made of paper, it is specifically made from a raw material liquid having a Japanese paper raw material and a synthetic resin pulp raw material, and has elasticity that can correspond to the elasticity of the veneer material. have. The base plate for bonding the veneer material and the backing material 4 is preferably a base plate having a smooth surface and appropriate heat resistance and strength. For example, a synthetic resin plate such as a duralumin plate or a polyester plate and a synthetic resin plate Veneer board, etc. A paper pattern is laid on the base plate as an underlay, but if the backing material 4 adhered to the base plate and the material are easily peeled off, the paper pattern is not always required.

<Heat crimping process>
In the heat crimping step, the veneer material is placed on the upper surface of the backing material 4 coated with the adhesive and heat crimped. The heating means is, for example, a heating press device, and the heating press is performed for about 5 to 10 seconds at a pressure of 100 kilograms / square centimeter and a heating temperature of about 100 degrees.

<Polishing finish process>
In the polishing finishing step, the backing material 4 is heat-bonded and the veneer material is polished and finished by a sander. In the polishing finish, the abrasive material (sanding belt) is brought into contact with the veneer material multiple times. As for the contact pressure, the pressure at the first contact is low and the pressure at the subsequent contact is high. Specifically, the abrasive has a roughness of, for example, about 240. The initial contact pressure is the pressure of the air pad that presses the abrasive from the opposite side of the polishing surface, for example, about 0.05 to 0.2 kg / square centimeter, and the subsequent contact pressure is about three times the pressure of the first time. Is. The polishing finishing step is appropriately omitted. Polishing may be performed after the veneer sheet 1 is attached to the product.

<Product peeling process>
In the product peeling step, the veneer material integrated with the backing material 4 is peeled off from the base plate to obtain the veneer 5 which is the predecessor of the veneer layer 3. The veneer 5 is inspected for cracks, tears, cracks and the like. Since the paper pattern is attached to the base plate, when the veneer 5 is peeled off, the backing material 4 does not stick to the base plate but sticks to the veneer 5 side, and is very easy to peel off.

<Adhesion process for leather layers, etc.>
In the process of adhering the leather layer or the like, the veneer sheet material is produced by attaching the leather material, which is the predecessor of the leather layer 2, to the back surface of the veneer 5 via an adhesive. A highly heat-resistant adhesive is applied to the surface of the leather material by spraying or the like, and the veneer 5 is attached onto the surface. In the case of the slicer as well, the slicer is attached to the back surface of the veneer 5 via an adhesive or a seal as in the case of the leather layer 2.

<Surface coating process>
In the surface coating step, the polyurethane resin paint is applied to the surface of the veneer sheet material on the veneer 5 side to produce the veneer sheet 1. First, the veneer sheet material is polished with sandpaper or the like having a particle size of 150 for the purpose of removing dirt and making the material state uniform. Next, the polyurethane resin paint (undercoat layer 7) in which the main agent and the curing agent are mixed and appropriately diluted is applied to the surface of the veneer 5 in an amount of 80 g / square centimeter by air spray or the like. Next, the veneer sheet material is left to dry for 8 hours in an environment of about 20 degrees. Next, the veneer sheet material is fluff-removed and polished with No. 400 sandpaper or the like. Next, a polyurethane resin paint (topcoat layer 8) having a composition different from that of the previous polyurethane resin paint is applied to the surface of the veneer 5 by an air spray or the like in an amount of 75 g / square centimeter, and under an environment of about 20 degrees. Then, it is left for 8 hours and dried.

<Coloring process>
Here, the veneer sheet material may undergo a coloring step after being polished with sandpaper having a particle size of 150 or the like and before the polyurethane resin paint is applied. In the coloring step, a colored paint of an arbitrary color is applied by a spray or the like, and after the excess colored paint is wiped off with a waste cloth or the like, it is dried in an environment of about 20 degrees for 4 hours.

Through the above steps, the veneer sheet 1 is completed. If the veneer layer 3 has undergone the coloring step, the veneer layer 3 becomes the veneer sheet 1 colored with an arbitrary color, and if the veneer layer 3 has not undergone the coloring step, the veneer layer 3 becomes the veneer sheet 1 having a natural color.

The veneer sheet 1 is used for the design surface of various clothing accessories, the surface of furniture, and the like. FIG. 2 shows clothing accessories using the veneer sheet 1, and FIG. 3 shows furniture using the veneer sheet 1.

Accessories are accessories other than clothing and household goods, and include, for example, bags, shoes, slippers, belts, photo frames, accessories, and the like. As shown in FIG. 2, the veneer sheet 1 is used for the design surface of the bag 9. Here, the design surface refers to a portion exposed in appearance, and the design surface of the bag is mainly the surface, and since the inside is also exposed when the bag is open, the inside is also included.

Furniture includes, for example, beds, chests of drawers, dressers, desks, chairs and the like. As shown in FIG. 3, the veneer sheet 1 is a bed 10 and is used on the surface of the headrest portion 11 and the like. In addition, for example, it is also used for the drawer surface of a chest of drawers, the door surface of a dresser, the top plate of a desk, the surface of a storage shelf provided on a study desk, the surface of a drawer, the backrest of a chair, a seat plate, and the like.

As described above, in the present embodiment, the veneer sheet 1 includes a leather layer 2 and a base layer, a veneer layer 3 bonded to the surface of the leather layer 2 and the base layer with an adhesive, and the veneer layer. It has a coating layer 6 coated on the surface of 3. The veneer layer 3 is formed by bonding the veneer 5 to the backing material 4 of the non-woven fabric via an adhesive. The coating layer 6 is composed of an undercoat layer 7 made of a polyurethane resin paint and a topcoat layer 8 made of a polyurethane resin paint having a composition different from that of the undercoat layer 7, and the undercoat layer 7 and the topcoat layer 8 are blended. Is as follows.
<Undercoat layer 7>
Main agent: Hardener: Diluted solution (thinner) = 100: 50: 100
<Topcoat layer 8>
Main agent: Hardener: Diluted solution (thinner) = 100: 25: 40
That is, since the coating layer 6 impregnates the veneer layer 3 and protects the veneer layer 3, it will not be damaged even if the veneer layer 3 is curved, and the coating layer 6 will not be cracked or the like. For example, by winding the veneer sheet 1 around a metal rod having a diameter of 2 mm and a metal rod having a diameter of 4 mm, even if the veneer sheet 1 is bent 180 degrees, cracks and the like do not occur. Therefore, the veneer sheet 1 can be used for a curved portion or a portion premised on being curved. Further, the undercoat layer 7 suppresses fluff on the surface of the veneer layer 3, and the topcoat layer 8 realizes a smooth feel.

In the present embodiment, the veneer sheet 1 can be used as a design surface for a bed 10, a bag 9, or the like. Therefore, a clothing accessory or the like having the texture of natural wood by the veneer 5 is realized.

In this embodiment, the veneer layer 3 is colored. Therefore, the veneer sheet 1 can be appropriately adapted according to the environment and the situation.

In another embodiment of the present invention (not shown), the veneer sheet does not have a leather layer or a base layer. That is, the veneer sheet according to the other embodiment is composed of a veneer layer and a coating layer. Even with this configuration, the same effect as that of the veneer sheet 1 described above is obtained, and on the other hand, it is also used for wallpaper and the like.

Hereinafter, examples of the present invention will be shown.
