In particular, recently, a lot of decorative boards using natural veneer have been used.

The natural veneer is obtained by cutting the wood thinly. Such natural veneer is very thin and easy to damage, vulnerable to moisture and very difficult to adhere to the plate, so that kraft paper is impregnated with phenolic resin. It is used in the form of a sheet, which is a thermo-compression layer of a laminated layer, a printing sheet impregnated with a melamine resin and a dry protective layer impregnated with a melamine-impregnated dry sheet on top of the printing layer.

However, the conventional veneer using the natural veneer had a problem that all the curvature of the surface of the natural veneer has been flattened by the flat surface of the press during the thermal compression process.

That is, the curvature of the natural veneer, for example, the shape, pattern, texture, and feel of the veneer, is not expressed on the upper surface of the protective layer but is merely expressed in a planar form.

This is because the overlay paper, which is impregnated with melamine, is directly melted and flattened by the flat surface of the press during the thermal compression process.

In order to prevent this problem, in the thermocompression process, grooves are formed on the flat surface of the press or other methods are applied. However, in this way, the curvature of the natural veneer can be expressed on the surface of the decorative plate, that is, the upper surface of the protective layer. There was no limit.

The present invention has been invented to solve the above problems of the prior art, kraft paper layer impregnated with phenolic resin, dry paper impregnated with melamine resin, and dry paper and overlay paper on the printing layer layer of the melamine The thermal impregnation of the impregnated dry protective layer, but it is the purpose of providing excellent merchandise because the curvature of the natural veneer, that is, the shape, pattern, texture, and feel is expressed in three dimensions and naturally without damage to the surface of the overlay paper.

This invention,

Laminate kraft paper impregnated with phenolic resin, dry kraft paper impregnated with melamine resin, and dry paper layer laminated on top of the printed paper layer and dried with natural veneer and overlay paper with a melamine impregnated dry protective layer, and then press-bonded to prepare a cosmetic plate. In shipping;

The release paper (or release film) is thermally compressed by inserting and placing kraft paper between a single release paper (or release film) or a double layer release paper (or release film) and the multilayer release paper (or release film) on the protective layer. ) Cushions the protective layer and expresses the curvature of the natural veneer on the surface of the protective layer in three dimensions.

The present invention is a thermal kraft paper layer impregnated with a phenolic resin kraft paper, dried printing paper impregnated with a melamine resin and a dry protective layer impregnated with the natural veneer and overlay paper on the upper layer of the printing paper, and a dry protective layer of impregnated with a melamine on the top of the overlay paper Since the release paper (or release film) having excellent elasticity and release property is placed on a single layer or a double layer and thermally compressed, the bending of the natural veneer, that is, the shape, pattern, texture, and touch, is expressed in three dimensions and naturally without damage to the overlay surface. It has the effect of providing excellent merchandise.

Hereinafter, the manufacturing method of the present invention will be described in more detail with reference to the accompanying drawings.

That is, the present invention, as shown in Figures 1 and 2, kraft paper layer (1) dried kraft paper impregnated in phenolic resin, printing paper layer 2 impregnated printing paper in melamine resin and natural veneer on the printing paper layer In laminating the (3) and the overlay paper with the melamine-impregnated dry protective layer (4), and manufacturing the decorative plate (5) by thermocompression bonding,

Place the release paper or release film 10 on the protective layer 4 and heat-compression so that the release paper or release film cushions the protective layer while the curvature of the natural veneer is expressed on the surface of the protective layer three-dimensionally and naturally. It provides a way to be compressed.

That is, the curvature of the natural veneer, that is, the shape, pattern, texture, and feel is expressed in three-dimensional and natural as it is without damage to the surface of the overlay paper, the purpose is to provide excellent merchandise.

At this time, the present invention, as shown in Figures 3 and 4, the release paper or release film 10, 10 on the protective layer 3 is placed in a multi-layer, kraft paper 20 between the multilayer release paper or a release film. It provides a method for compressing the decorative plate so that the release paper or the release film cushions the protective layer while inserting the sheet) so that the bending of the natural veneer is three-dimensional and naturally expressed on the surface of the protective layer.

And of course, the natural veneer may be formed in a variety of forms having a natural or artificial bend.

The following describes the method of the present invention in more detail.

First, the present invention is a kraft paper layer (1) and dry kraft paper impregnated in a phenolic resin, the printing paper layer impregnated in a melamine resin (2) and the natural veneer on top of the printing paper layer as in the embodiment of Figs. (3) and the overlay paper were prepared by laminating a meramin-impregnated dry protective layer (4) in order.

And a release paper or a release film 10 is placed on the protective layer.

In this state, the kraft paper layer (1), the printing paper layer (2), the veneer layer (3), and the protective layer (4) are integrally fused while pressing by pressing the flat surface of the press on the release paper or the release film. .

At this time, the shape of the natural veneer of the veneer layer 2 by the release paper or the release film 10, that is, the shape, pattern, texture, and feel of the natural veneer without the surface of the protective layer 3 as in the prior art It is to play the role of expressing three-dimensional and natural.

In particular, the curvature of the veneer layer 3 is three-dimensionally expressed in the protective layer 4 before the veneer layer 3 is fused with the protective layer 4 due to the cushioning action of the release paper or the release film 10. It will be possible because.

In addition, the release paper or the release film 10 is excellent in releasability, and thus, only the release paper or the release film 10 is simply separated and removed from the upper portion of the protective layer 4 after thermal compression as described above.

The kraft paper layer 1, the printing paper layer 2, the veneer layer 3, and the protective layer 4 are integrally fused together by cooling, and the bending of the natural veneer on the surface of the protective layer 4 is three-dimensional and natural. You will get a makeup plate.

On the other hand, the present invention is a double layer of release paper or release film (10) 10 and the double layer of release paper or release film (10) (10) on the protective layer (4) as in the embodiment of Figures 3 and 4 The kraft paper layer (1), the printing paper layer (2), the wood veneer layer (1), the printing paper layer (2) 3) The protective layer 4 is integrally fused.

At this time, but the cushioning action by the release paper or release film 10, 10 of the multilayer, in particular while providing a more effective cushioning effect by the kraft paper 20 between the release paper or release film 10, 10 of the multilayer The role of the natural veneer of the layer 3, that is, the shape, pattern, texture, and feel of the natural veneer, is more excellent in three-dimensional and natural expression without being flattened on the surface of the protective layer 4. .

After thermal compression, the release layer, the release film 10, 10, and the kraft paper 20 of the multilayer are simply separated and cooled, and then cooled, and the kraft paper layer 1, the printing paper layer 2, and the veneer layer 3 are removed. In this case, the protective layer 4 is integrally fused to obtain a decorative plate in which the bending of the natural veneer is three-dimensional and naturally expressed on the surface of the protective layer 4.

Therefore, in the above-described embodiments of the present invention, the upper surface of the protective layer is formed by a method of thermally compressing a release paper or a release film on the protective layer during the process of manufacturing the decorative plate 5 by thermal compression. It prevents the flattening and the curvature of the veneer is expressed as it is three-dimensional and naturally on the surface of the protective layer, and it is widely used to have the aesthetic sense of natural veneer in decorative materials, surface materials, and flooring materials in a state of being adhered to the wallpaper as well as the wallpaper.
