Description

  The present invention relates to a flooring in which a single board and a resin film printed with a wood grain pattern are attached to a plywood, and in particular, it is possible to give depth to the pattern, and various types of resin films printed with wood grain are available. The present invention relates to a flooring material that can give a color tone and is less susceptible to scratches such as scratches.

  For the flooring, a single board made by slicing natural wood such as oak and cherry into a thickness of about 0.3 mm is laminated to a plywood that is laminated with several thin boards so that the grain is perpendicular to each other. There is a multilayer structure with an opaque resin film printed with a wood grain pattern on it. Such a flooring material is characterized by being easier to construct than a single-layered flooring material, which is a natural wood such as oak, pine, etc., which is called muk material. In addition, by changing the wood grain pattern and color printed on the resin film, the texture of the flooring material can be made different, such as a walnut-like flooring material or a cherry-like flooring material.

  However, since such a resin film is opaque, there is no depth in the finished flooring. In addition, the resin film is not only prepared for each texture such as walnut or cherry, but it is desirable that a difference in color appears, such as a lighter color or a darker color, even with the same texture. If it does so, the kind of resin film required at the time of flooring manufacture will increase, and a manufacturing process will become complicated.

  Furthermore, the floor material as described above is easily damaged because the veneer is thin. In particular, when moving furniture with casters, it is easily scratched by sand or dust.

  Accordingly, the present invention aims to provide a flooring that can give depth to the handle, can produce various shades even if the number of types of resin film printed with wood is small, and is less likely to be scratched. It is said.

  In order to achieve the above object, a flooring material of the present invention includes a plywood obtained by stacking a plurality of thin plates, a single plate attached to the plywood via an adhesive layer, and a wood grain printed thereon. And a transparent or translucent resin film to be attached.

  Further, the resin film is an olefin film, the single plate is formed by laminating thin plates and sliced in a direction intersecting the laminated surface, or the adhesive layer is thermosetting. The single plate may be formed of resin, or the single plate may be formed by dyeing the thin plate with the same color.

  According to the flooring of the present invention, a single plate is bonded to a plywood obtained by stacking a plurality of thin plates, and a transparent or translucent resin film printed with wood is pasted thereon. The color of the can be seen through from the bottom of the resin film, so that the depth of the handle of the finished flooring will appear. Also, since the color of the finished floor material changes by changing the color of the veneer, it is possible to make floor materials of various colors even if there are few types of resin films printed with wood grain.

  A veneer is made by laminating thin plates and slicing them in the direction intersecting the laminated surface, so that the uniform wood grain pattern formed on the veneer can be seen from under the resin film and the floor pattern is deep. Get out.

  By adopting a configuration in which the adhesive layer that bonds the plywood and the veneer is a thermosetting resin, the thermosetting resin soaks into the veneer, and the hardness of the veneer increases and the flaw is less likely to be damaged.

  By dyeing the thin plate used for the single plate with the same color, the single plate can be arranged in a certain color. Further, since the color of the finished floor material changes by changing the color to be dyed, it is possible to make floor materials of various colors even if there are few types of resin films.

Next, the flooring of the present invention will be described based on the drawings.
FIG. 1 is a cross-sectional view of the flooring of the present invention. The flooring 1 is composed of a plywood 2, an adhesive layer 3, a single plate 4 and a resin film 5.

  The plywood 2 is obtained by laminating a plurality of plates so that the respective grain lines intersect each other and bonding them with an adhesive. When the strength of one plywood 2 is insufficient, a plurality of plywoods 2 can be further stacked. Examples of the board used for the plywood 2 include broad-leaved trees such as China and hippopotamus, conifers such as cedar, pine, and hinoki, or southern materials such as lauan.

Further, the plywood 2 has a convex portion 21 on the right side of the drawing, and a concave portion 22 is provided at a position where the plywood 2 is fitted to the left convex portion 21. By fitting the convex portions 21 of one floor material 1 into the concave portions 22 of the other floor materials 1, the floor materials 1 can be connected to each other. Thus, a floor surface is formed by connecting a plurality of flooring materials 1 in the horizontal direction of the figure.
An adhesive layer 3 is formed between the plywood 2 and the single plate 4, and the single plate 4 is attached to the plywood 2 by the adhesive layer 3.

  FIG. 2 is a view showing a method for manufacturing a single plate. The veneer 4 is formed by laminating a plurality of thin plates 41 having a thickness D of about 2 mm to 3 mm in the vertical direction of the figure, and in a direction intersecting the laminated surface at the position of the slice position 42, that is, from the top to the bottom of the figure. It is the thing sliced toward. The width W of the sliced single plate 4 is 0.25 mm. In this way, by laminating the thin plates 41 and slicing them so as to intersect the laminated surface, a striped pattern having a spacing of 2 to 3 mm can be formed on the surface of the single plate 4. This striped pattern gives a grainy texture. Although it is sliced vertically in FIG. 2, it is also possible to widen the stripe pattern interval by slicing it obliquely with respect to the laminated surface. Striped patterns with a predetermined interval can be obtained depending on the angle of the slice with respect to the laminated surface.

  The thin plate 41 uses a broad-leaved tree such as a hippopotamus or a conifer such as cedar. Of these thin plates 41, those having the same color are selected and laminated. As a result, the flooring 1 having a certain texture can be manufactured. Further, by changing the number of laminated thin plates 41, a single plate 4 having a desired size can be obtained. When making a large size flooring with a conventional veneer that slices natural wood, it is manufactured by arranging multiple veneers on a plywood, but with a veneer that slices natural wood, it can be arranged in a certain color. difficult. By laminating and slicing the thin plates 41 as described above, even if the color of the thin plate 41 is slightly different, when the single plate 4 is used, the color difference becomes a striped pattern, and a grainy texture is obtained. However, when the color of the thin plate 41 is extremely different, an unnatural stripe pattern is formed. Therefore, it is preferable to use the thin plate 41 having the same color as much as possible. At this time, the thin plate 41 may be dyed in advance with the same color.

  Returning to FIG. 1, the adhesive layer 3 is formed of a thermosetting resin such as hot melt. When the veneer 4 is bonded to the plywood 2, the thermosetting resin is sufficiently infiltrated into the veneer 4 and attached to the plywood 2. When the thermosetting resin is cured, the hardness of the veneer 4 is also increased, so that the completed flooring 1 is not easily damaged by furniture such as casters, scratches caused by sand or dust. In particular, the veneer 4 shown in FIG. 2 is in a state in which the edge surface of the thin plate 41 is aligned with the bonding surface with the plywood 2. Therefore, since the thermosetting resin easily penetrates into the single plate 4 through a conduit or the like, it is easy to increase the hardness of the single plate 4.

  A resin film 5 is attached to the surface of the veneer 4 with an adhesive such as a water-soluble adhesive or a rubber adhesive. The resin film 5 is a transparent or translucent resin printed with an emphasis on the wood grain pattern and EB coating (Dai Nippon Printing Co., Ltd. technology) that cures the resin by irradiating an electron beam. is there. A polyolefin film can be used as the resin film 5. Since the polyolefin film does not generate harmful gases such as dioxin even when incinerated, the unnecessary flooring 1 can be incinerated and disposal becomes easy.

  Since the resin film 5 is transparent or semi-transparent, when it is attached to the veneer 4, the stripe pattern of the veneer 4 can be seen through under the wood grain pattern printed on the resin film 5, and the pattern on the surface of the flooring 1. The depth comes out. Further, by using a single plate 4 of a different color, the color of the finished flooring 1 can be changed without changing the printing of the resin film 5. For example, if a resin film 5 is pasted on a dark-colored veneer 4, a dark-colored flooring 1 can be obtained, and if a light-colored veneer 4 resin film 5 is stuck, the same resin film 5 can be obtained. The finished flooring 1 has a bright hue.

It is sectional drawing of the flooring of this invention. It is a figure which shows the manufacturing method of a single plate.
