Description

Deep embossed natural veneer panel {DEEP EMBOSSED VENEER PANEL}

The present invention relates to a natural veneer panel, and more particularly, natural veneer is thin plywood, medium density fiber board (MDF: Medium Density Fiber Board), high density fiber board (HDF: High Desity Fiber Board), PVC tile, steel panel (steel A method for producing a deep embossed natural veneer panel which is attached to a surface of a panel, etc., and has a deep concavo-convex on the surface to give a three-dimensional appearance, texture, and feel to the surface, and a deep embossed natural veneer panel manufactured by the method. will be.

Recently, thin wood is cut into 0.182mm to 0.5mm thickness by using a slicer to obtain a thin natural veneer, and after cutting the natural veneer, it is made of natural veneer sheet by gathering or weaving several sheets with resin or bonded yarn. Panels having a natural veneer surface are fabricated at low cost by bonding to MDF, HDF (hereinafter MDF or HDF is also referred to as "board"), plywood, synthetic resin panels, and the like. In addition to this, the surface of the unevenness or embossment is attached to a thin MDF by attaching a high pressure laminate (HPL) in which a phenol-impregnated paper is placed on a natural veneer sheet or a natural veneer sheet. It is also used as a surface material of a kitchen furniture door by pressing the formed steel plate so that irregularities or embossments are formed on the surface of natural veneer.

However, conventional veneer or embossed natural veneer panel (referred to herein as "embossed veneer panel") has the following disadvantages in its products and manufacturing process, the improvement is that It is required.

According to the conventional embossed natural veneer panel manufacturing process, after applying an adhesive to a substrate such as a thin MDF and laminated a natural veneer sheet on the upper surface of the steel plate on which the uneven or embossment is formed ( Strongly press the " embossed steel plate " to form irregularities or embossments on the surface of the laminated natural veneer sheet. In order to make sure that the unevenness or embossment is formed on the panel surface in this process, the embossed steel plate must be strongly pressed, but it cannot be applied beyond a certain pressure because the substrate can be damaged if it is pressed too hard. This means that irregularities or embossments cannot be deeply formed on the panel surface.

In addition, the embossed natural veneer panel manufactured by the conventional embossing process is because the pressure is directly applied to the substrate in the pressing process by the embossed steel plate to change the fiber density between the top and bottom of the panel, the panel over time There is a problem of this bending. To prevent this bending, a balance paper should be attached to the bottom of the substrate.

In addition, natural veneer is easily worn or damaged by friction during use, so that the surface is painted after the embossing process.

Therefore, according to the conventional embossed natural veneer panel manufacturing process, it has to go through various processes to obtain a stable product, and nevertheless there is a disadvantage that the surface irregularities or embossment can not be deepened as necessary.

The present invention devised to solve the problems of the above-described method of manufacturing a natural embossed natural veneer panel is a method of manufacturing a deep embossed natural veneer panel that can form deep unevenness or embossment to sufficiently display a three-dimensional effect on the surface And it is an object to provide a deep embossed natural veneer panel produced by the method.

Another object of the present invention is to provide a method of manufacturing a deep embossed natural veneer panel without bending even without attaching a balance paper on the lower surface of the substrate and a deep embossed natural veneer panel manufactured by the method.

Still another object of the present invention is to provide a deep embossed natural veneer panel and a deep embossed natural veneer panel manufactured by the method, which can prevent surface reinforcement and warpage in one step without coating the surface. .

The method for producing a deep embossed natural veneer panel according to the present invention to achieve the above object is to form a concave-convex or embossment on the surface of the veneer sheet by laminating a natural veneer sheet and a substrate and press with an embossed steel plate In the natural veneer sheet, an adhesive cushioning material is inserted, and the melamine impregnated overlay paper is laminated on the natural veneer sheet, and the sheet is thermocompressed with an embossed steel plate.

It is preferable that the said adhesive cushioning material is urethane impregnated glass fiber or melamine impregnated paper.

In order to ensure bending prevention, the adhesive cushion and the natural veneer sheet may be sequentially stacked on the lower part of the substrate, and then thermocompressed integrally.

According to the present invention having the above-described configuration, the unevenness or embossment can be deeply formed on the surface of the natural veneer due to the expansion and contraction of the adhesive cushioning material, so that the surface can fully exhibit a three-dimensional effect, and the embossed steel plate The pressure is absorbed to the adhesive cushioning material to some extent so that the fiber non-uniformity does not occur between the upper and lower panels, and the adhesive cushioning material itself performs the balancing function, so the bending is not necessary even if a separate balance paper is attached to the lower part of the substrate. There is no, and there is an effect that can produce a deep embossed natural veneer panel that can prevent the surface reinforcement and warpage in a single process without a separate surface coating.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a deep embossed natural veneer panel according to the present invention when manufactured by embossed steel sheet one by one, an exploded perspective view showing the stacking order of each component, Figure 2 is a deep embossed natural veneer panel according to the invention When manufactured by two sheets of embossed steel plate, the separation perspective view showing the stacking order of each component, Figure 3 is a perspective view of a deep embossed natural veneer panel according to the present invention, Figure 4 to ensure bending prevention In order to show the case where the adhesive cushion and the natural veneer sheet is further attached to the lower substrate, respectively.

1 shows a lamination order of an embossed steel plate 1, a melamine impregnated overlay paper 3, a natural veneer sheet 5, an adhesive cushioning material 7, and a substrate 9 that are laminated before thermocompression bonding.

The embossed steel plate 1 is formed by cutting unevenness or embossment in the lower part of a steel plate such as a stainless steel plate. At this time, the direction of the uneven or embossment is preferably formed to proceed in the same direction as the pattern result of the natural veneer sheet (5).

The melamine impregnated overlay paper 3 is formed by dispersing the wear-resistant silica or alumina in cellulose paper and then impregnating the overlay paper with a melamine resin, which is a thermosetting resin, and then drying it. The melamine impregnated overlay paper 3 is transparent when thermally compressed.

As the natural veneer sheet (5), it is preferable to use high pressure laminate (HPL) pressed by high pressure by kneading a thermosetting resin or kraft paper impregnated with a thermosetting resin and then impregnating an adhesive with an adhesive. Can be used as it is without a closet.

The adhesive cushion material 7 is preferably selected from urethane impregnated glass fibers or melamine impregnated paper. In particular, the melamine impregnated paper used at this time is thicker than the melamine impregnated overlay paper.

The substrate is selected from thin MDF (Medium Density Fiber), HDF (High Density Fiber), Particle Board (PB), Plywood (Plywood) and the like.

1 and 2, in order to manufacture the deep embossed natural veneer panel according to the present invention by heat press, the substrate 9, the adhesive cushioning material 7, The natural veneer sheet 5, the melamine impregnated overlay paper 3 and the embossed steel sheet 1 are sequentially stacked or double stacked so that these components are symmetrical on the top and bottom. In the case of double stacking as shown in FIG. 2, two deep embossed natural veneer panels can be obtained by one thermal compression, thereby improving productivity.

When lamination is completed, the upper surface of the embossed steel plate 1 is thermally compressed by heat press to integrate the substrate 9, the adhesive cushioning material 7, the natural veneer sheet 5, and the melamine impregnated overlay paper 3. To be bonded. At this time, thermocompression bonding by heat press is thermocompression while increasing the temperature up to 160 ° C under pressure of 30-35Kg / cm 2, and thermocompression bonding under 10 ° C at 100 ° C and 40-50 minutes at 100 ° C or higher. Do. This is the pressure, temperature and time required for the melamine of the melamine impregnated overlay paper 3 to melt to some extent and seep into the natural veneer sheet 5 to cure.

Referring to FIG. 3, the adhesive cushion 7 is stretched and contracted according to the unevenness or embossment of the embossed steel plate 1 so that the unevenness or embossment on the surface of the natural veneer sheet 5 is sufficiently deeply formed. Make it as possible. Due to the elasticity of the adhesive cushioning material 7 at the time of thermocompression, as shown in FIG. 2, it is also possible to manufacture two deep embossed natural veneer panels by one-time thermocompression.

In addition, the adhesive cushioning material 7 absorbs the pressure on the substrate 9 during the thermocompression bonding process, thereby preventing the fiber density of the substrate from changing up and down, and after curing, the hardness becomes greater than the hardness of the substrate. It is to prevent the bending of.

Referring to FIG. 4, in order to ensure bending prevention, the adhesive cushion 7 and the natural veneer sheet 5 may be sequentially stacked on the lower part of the substrate and thermo-compressed integrally. In this case, a balance between material and fiber density between the upper and lower substrates is achieved, which is effective for preventing bending.

In addition, since the melamine impregnated overlay paper 3 is thermally pressed together to coat the surface of the natural veneer sheet 5, the coating of a separate coating is unnecessary.

As mentioned above, although the present invention has been described with reference to the accompanying drawings, the scope of protection of the present invention is not intended to be limited thereto. Therefore, the scope of protection of the present invention is the scope of the claims and equivalents thereof. It should be interpreted as affecting.
