Abstract

(57) [Summary] [Purpose] To provide a veneer material that is flexible and has excellent processing performance for curved surfaces. [Composition] Laminated nonwoven fabric is thinly sliced from natural wood, laminated with non-woven fabric, and then laminated with thermoplastic film on the surface. A veneer material characterized by being put in.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a veneer material, which is more flexible than ever and is suitable for curved surfaces. It is intended to provide a new veneer material with excellent workability.

[0002]

[Prior art]

  The veneer made by thinly slicing natural wood is traditionally used to reduce the cost of solid wood. It can be attached to plywood or particle board to create interior materials, flooring materials for housing, furniture, Widely used in home appliances and sundries. Another use is thin seams. Tooth-shaped veneer is attached to square or round material to make a pillar, or it is attached to wallpaper or curved surface for furniture. It is mainly used for high-end applications as a miscellaneous goods such as automobile interiors and stationery.

[0003]   However, this thin sheet-shaped veneer is usually designed so that the veneer does not come apart. A non-woven fabric is attached to the back, but it is difficult to grow as the original property of wood It is very difficult to do. Modify the veneer with chemicals to make it flexible or heat it. It is possible to bend to some extent, but it is expensive and troublesome and it is bad Is high, and there are drawbacks such as lack of mass productivity and limited shape, so improvement is desired. It was

[0004]

[Problems to be solved by the device]

  The present invention has been difficult until now by providing flexibility that conventional veneer materials do not have. To provide a veneer material that is stable, easy, and cheap to adhere even to a three-dimensional shape To do.

[0005]

[Means for Solving the Problems]

  First, thinly slice a 0.3 mm to 1 mm veneer with a non-woven fabric with an adhesive. And paste. This non-woven fabric is easy for the veneer to break or break easily. In addition to covering the Depending on the case, paper, PVC, polyethylene, polypropylene, acrylic Use of plastic film such as resin, polyester, urethane resin and metal foil Is also possible.

[0006]   Next, from the non-woven fabric side, a normal embossing machine, paper embossing machine or press machine. Etc. or emboss with a press etc. Using an extremely sharp embossed plate, make a cut in the layer of the veneer part Apply pressure to.

[0007]   In this case, the shape of the embossed plate is important. In order to eliminate vertical and horizontal orientation, tiles with fine and uniform shapes arranged regularly The shape pattern is effective. This small unit is a polygon or a circle or an ellipse and its A combination is desirable, and the length of one side or diameter is preferably about 0.5 mm to 2 mm. Is. Embossing and notching are usually on the back side so that the veneer surface is not scratched. However, in some cases, the veneer surface may be used.

[0008]   In order to further improve the ability to follow curved surfaces, embossing from the back side and notching To prevent scratches and cracks on the surface of the board, attach non-woven fabric, etc. 20 μm to 200 μm thick thermoplastic plastic film with good elongation on the surface of It is effective to stack rum. This thermoplastic film is polychlorinated Vinyl, polyethylene, polypropylene, acrylic resin, polyester, Ure Tongue resin and the like are possible. If these films are attached, the error from the table It is not suitable for embossing and notching.

[0009]

[Action]

  Compared to conventional veneer materials, laminated veneer materials cover folds and cracks . In addition, the adhesiveness with the base material is increased, and further embossing or fine The break makes it soft and bends freely vertically or horizontally, and in some cases it can be extended It has become possible.

[0010]

【Example】

An embodiment of the present invention will be described with reference to FIG. A nonwoven fabric 5 made of acrylic resin having a weight of 30 g / m ² was attached to a veneer 3 of sapele mahogany having a thickness of 0.5 mm with a urethane resin adhesive 4.

[0011]   Next, heat the surface of the veneer backing with a thickness of 80 μm and a plasticizer amount of 10 parts. Transparent plastic chloride is used as plastic plastic film 1 with ethylene vinyl acetate. It was pasted together with an adhesive 2 of a resin.

Next, using a press machine, an embossing plate 6 having a honeycomb-like (hexagonal) pattern with a difference in unevenness of 0.5 mm and a side length of 0.5 mm was used at a temperature of 80 ° C. and a pressure of 5 kg / cm ² . The embossing was performed under the condition that the pressure was applied for 5 minutes.

[0013]

[Effect of device]

  The veneer material according to the present invention is laminated to a deeper three-dimensional curved surface. Came to come. In addition, the conventional shape is stable and can be applied stably. This will reduce costs by reducing defects and increasing productivity.
