Description

Description: TECHNICAL FIELD The present invention relates to a veneer laminated material, more specifically, a veneer laminated material obtained by laminating a veneer and thin plates made of other materials.

[Conventional technology]

The single plate laminated material (LVL), which is made by laminating thin plate materials excluding knots and scratches in the same grain direction, has excellent aesthetics when processed in the thickness direction by cutting, etc. It is widely used as a building material for parts such as window frames, door frames, and frames that require decorative properties.

[Problems to be Solved by the Invention]

However, the above single-plate laminated material undergoes dimensional changes over time due to external factors such as heat and moisture in the air, and may cause shape changes such as warpage, so that, for example, a door frame is formed. In such a case, there is a problem that the building is bad and the door cannot be opened and closed smoothly, or conversely, a gap is generated between the door and the door frame.

Therefore, an object of the present invention is to provide a composite veneer laminated material which has the original decorative property of the veneer laminated material and does not cause dimensional change and shape change over time.

[Means for Solving the Problems]

As a result of various studies, the present inventors have found that the above object can be achieved by arranging two or more specific plate materials between laminated single plates.

The present invention has been made on the basis of the above findings, and is a composite veneer laminate obtained by arranging a bakelite plate 2 inside and laminating a plurality of veneers 1 and two bakelite plates 2. And two or more veneers 1a are arranged on the back and the back, respectively, with the grain of wood aligned in the same direction, and the interval between the two bakelite plates 2 is 10 to 20 mm, and a plurality of veneers are provided in the intervals.
The present invention provides a composite veneer laminated material (first invention), in which 1b is arranged. Further, the present invention provides a second invention in which phenol-impregnated paper is used instead of the Bakelite plate in the first invention.

[Action]

In the composite veneer laminate of the present invention, two bakelite plates or phenol-impregnated papers are inserted and laminated between a plurality of veneers with an interval therebetween, which is excellent for the whole laminate. It imparts dimensional stability and shape stability over a long period of time.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a partial perspective view showing an outline of a composite veneer laminated material of one embodiment according to the first invention, and FIG. 2 is a schematic transverse sectional view of the composite veneer laminated material.

The composite veneer laminated material of this example is obtained by laminating a plurality of veneers 1 with their wood grain aligned in the same direction, and at a predetermined interval between the veneers and the veneers with respect to two temperatures and moisture. The stable bakelite plate 2 is inserted and laminated.

Specifically, as shown in FIG. 2, seven veneers 1b are arranged between the two bakelite plates 2, and three veneers 1b are provided outside each bakelite plate 2. 1a is arranged.

The veneer plate and the bakelite plate-the veneer plate are firmly fixed with an adhesive. Further, each of the above single plates has a thickness of 2 mm, and each of the bakelite plates has a thickness of 1 mm.

In the composite veneer laminate of the present embodiment, three veneers 1a are laminated on the outside of the bakelite plate 2 in the same direction with the wood grain, so that the decorativeness is impaired even if cutting is performed in the thickness direction. Never happened. Moreover, dimensional changes and shape changes did not occur even after a long period of time. It can be understood that this is based on the fact that the reinforcing effect on the single plate is balanced because the two aluminum plates 2 are inserted.

The composite single-plate laminated material of the first invention is not limited to the above-mentioned one, but can be variously modified as described in detail below.

The thickness of the aluminum plate used is preferably 0.
It is 4 to 2 mm, and it is important that the number of laminated layers is two or more from the standpoint of balancing reinforcement, etc., and can be arbitrarily changed as necessary.

The thickness of the veneer used is preferably 1.0 to 3
mm, more preferably 1.3 to 3 mm, and the material thereof is not particularly limited.

In addition, it is located between the two bakelite plates 2 and 2, 1b in the figure.
A plurality of single plates shown in are provided, and the interval between the Bakelite plates 2 and 2 at that time is set to 10 to 20 mm, and preferably 15 mm or about that.

It is important that two or more veneers are arranged in the same direction on the front surface and the back surface so that the composite veneer laminated material to be formed has a decorative effect. Is. That is, it is located outside the bakelite plate. It is necessary that two or more veneers shown by 1a in the figure are used, and that the wood grain is aligned in the same direction.

In addition, a normal laminated material manufacturing technique can be applied to the lamination of the single plate 1 and the bakelite plate 2. that time,
An adhesive for plywood can be used to fix the single plate 1 and the bakelite plate 2, and it is preferable that the surface of the bakelite plate 2 is roughened and bonded by corona discharge treatment, sandpaper treatment, or the like. Further, it is preferable to fix the single plates 1 to each other with an adhesive for plywood such as urea or melamine.

The composite veneer laminate of the second invention uses phenol-impregnated paper instead of the bakelite plate of the first invention, and the other structure is basically the same as that of the first invention.

The phenol-impregnated paper used preferably has a thickness of 1.2 to 2 mm, and an adhesive for plywood can be used to fix it to the veneer 1.

〔The invention's effect〕

The composite veneer laminate of the present invention has the original decorative properties of the veneer laminate, and has the excellent property of not causing dimensional change or shape change over time.
