Description

[Detailed description of the invention] Conventionally, when manufacturing decorative floorboards to which precious wood veneers with a thickness of 3 mm or more are glued, the precious wood veneers have been manufactured by sawing the precious wood. However, with sawing, an amount of wood equivalent to about 2 mm thick is lost as sawdust every time a single veneer of precious wood is produced, making it extremely wasteful as the resource for namewood boards is being depleted. Ta. There are also decorative floorboards with thin sliced precious wood veneers of about 0.2 to 0.5 mm glued to the surface of the board, but because the sliding precious wood veneers on the surface of these decorative floorboards are thin, they do not have a solid feel and are very flat. It felt cheap and cheap, and had the disadvantage of poor surface abrasion resistance.

As a result of various studies to solve the above-mentioned drawbacks, the inventor of the present invention found that if multiple pieces of rotary precious wood veneer or sliced precious wood veneer are laminated and glued together,
I completed this idea knowing that it was a good idea. Moreover,
Surprisingly, it has been found that by laminating and bonding a plurality of the above-mentioned wood veneers, physical performance is improved and production workability is also improved.

This invention will be explained in detail using examples.

1 is a substrate such as plywood, verteckle board, hardboard, sleigh, pulp cement board, calcium silicate board, etc., and two sliced precious wood veneers 3 are laminated and bonded to the surface of the board through an adhesive layer 2. There is. Of these two sliced precious wood veneers, the upper one is thinner than the lower one. 4 is an adhesive layer that adheres the sliced precious wood veneers 3 together, and the most suitable material is a transparent adhesive or paper or cloth that becomes transparent after being impregnated with a transparent adhesive; Opaque adhesives may be used if the veneer can be seen through.
In addition, the sliced precious wood veneer 3a on the front side uses a high quality sliced precious wood veneer, and the sliced precious wood veneer 3b on the back side uses a sliced precious wood veneer that does not hold up to the front side, and defective products are used as much as possible. However, it is also possible to try to save resources. 5 is a top coating layer.

Next, to describe the manufacturing method of this invention, after applying an adhesive such as urea resin adhesive, acrylic resin adhesive, urethane resin adhesive, acrylic urethane resin adhesive, etc. to the substrate surface, After temporarily adhering the boards and applying an adhesive to the surface thereof, a sliced precious wood veneer having a thickness thinner than the above-mentioned precious wood veneer is temporarily adhered and hot-pressed to manufacture. After sanding the surface, apply a top coat and let dry. In addition, the sliced precious wood veneers may be bonded to each other in advance through an adhesive layer, and then the sliced precious wood veneers laminated and bonded as described above may be adhered to the substrate.

Although the above embodiments are described using sliced precious wood veneers, rotary precious wood veneers may also be used, or sliced precious wood veneers and rotary precious wood veneers may be mixed. in this case,
The surface quality tends to be slightly better when a sliced precious wood veneer is placed on the front side than a rotary precious wood veneer.

Since this invention is constructed as described above, it has the following effects.

Unlike sawn wood veneers, it can be used without wasting expensive wood.

Since two thin veneers of precious wood are laminated, you can obtain decorative floorboards with little warping and no warping or irregularities.

Compared to thick veneer of precious wood, it has a very good drying effect and has a good peeling surface, so less sanding is required during finishing, resulting in very good workability and productivity, and when applying top coat to the surface. It is possible to obtain a decorative floorboard that can be applied uniformly and has a good surface quality.

Of the two precious wood veneers, the upper one is thinner than the lower one, and the lower one has a slightly lower quality wood veneer. This not only makes it possible to use precious wood veneers that were previously unusable, making effective use of precious wood, but also forms a layer of precious wood veneer with a certain thickness by laminating two precious wood veneers. When doing so, it is possible to obtain a decorative floor board with superior clutch resistance by reducing the thickness of the top precious wood veneer rather than by laminating two veneers of the same thickness.

Unlike thick precious wood veneers, two thin precious wood veneers are laminated with an adhesive, so the intermediate adhesive layer improves the surface strength (impact strength) of the decorative floorboard.

Even if you use thin precious wood veneers, you can
Since the sheets are laminated, the appearance is no different from using a thick veneer of precious wood, and it has a solid and luxurious feel. Furthermore, even if some of the thin wood veneers on the front side wear out, there is no problem because the wood veneers are laminated together using an adhesive that allows the lower wood veneers to be seen through.

[Brief explanation of the drawing]
