Description

Large panel for furniture and interior and exterior materials and its manufacturing method {The Art panel and Manufacturing method}

The present invention relates to a large panel for furniture and interior and exterior materials, and a method of manufacturing the same, and more specifically, to a conventional MDF / PB panel used in furniture and interiors of the building, such as jangnon, desk, etc., the sheet is printed in various color tones By adsorbing the pattern printed on Gina or sheet paper to the panel and then coating it to be used, it is possible to reduce the manufacturing cost significantly and to add aesthetics to the large panel for furniture and interior materials and its manufacturing method. It is about.

Generally, the panel used for furniture and interior and exterior materials is high quality and expensive original solid wood or processed MDF / PB panel. However, MDF / PB panel with low cost is generally preferred for general panel materials. have.

Medium Density Fiberboard (MDF) is a medium-density fiber board made of wood plate with a density of 0.4 to 0.8 g / cm3 formed by combining and molding the wood fiber obtained by dissolving it at high temperature using wood as its main raw material with synthetic resin adhesive. In general, it is possible to produce up to 3 ~ 30㎜ thickness has been used in various applications such as furniture and interior and exterior materials.

On the other hand, PB panel is a wood plate material which is formed and manufactured in a plate shape by spraying an adhesive to a small piece of wood and applying a thermopneumatic method, and is usually produced in a thickness of about 15 to 18 mm.

The MDF / PB panel as described above has a significant advantage in terms of durability and price because it is a processed panel, but the exterior has a disadvantage in that the aesthetics are not good because it is seen as a smooth texture (or a pattern of compressed sawdust). In order to satisfy this problem, conventional synthetic resin or paper sheet, which has previously been inscribed on the surface of MDF / PB panel, is glued by adhesive (chemical bond) and hot-pressed for adhesion (called 'gravure printing method') or one ton on MDF / PB panel surface. After painting, the coating finish (called 'paint printing' or 'high-gloss printing') was applied, and recently, a patterned silk paper was placed on the surface of the MDF / PB panel and the glass was finished on it. Finishing method) or silk-screen printing on the surface of translucent panel such as acrylic / glass and combined with MDF / PB panel to express the pattern. By adopting (silk screen printing method), and was finished esthetic sense of MDF / PB panel surface.

However, in the conventional gravure printing method, in order to engrave a pattern on a synthetic resin or a paper sheet, a roller-shaped circular copper plate has to be produced, and only a pattern of a certain pattern can be printed, and thus there is a limitation of the expensive copper plate size, thereby producing a large size. Since only one ton of color can be printed per circular copper plate, it is inevitable to increase the number of copper plates in the case of a pattern that requires a large number of colors. There were many insignificances in expression.

In addition, the painting printing method (high-gloss printing method) is usually painted in one color on the surface of the MDF / PB panel and then finished with a general coating on the surface there is a significant advantage in terms of high gloss of the surface, but painting There is a disadvantage in that it is impossible to express the picture.

In addition, the glass finishing method is to cover the glass (or transparent acrylic) on the surface of the MDF / PB panel with the pattern expressed on the surface, there is an advantage that does not require coating work, but the material cost of the silk paper is expensive When directly attached to the surface of the MDF / PB panel with adhesive, the unique pattern of the MDF / PB panel is exposed and reflected on the outside, so the color of the unique pattern is different. Due to its limitations and weight, it is not easy to handle during work and is usually installed in a part of a door such as a small farm.

In addition, the silk-screen printing method also has a disadvantage in that it is difficult to handle during work because it is limited to the manufacturing size because it is combined with the MDF / PB panel by printing a pattern on the surface of the translucent panel such as acrylic / glass.

On the other hand, in recent years, photorealistic printing has been performed to express various tone patterns such as actual pictures on sheet paper (including cloth, paper, photo paper, and synthetic resin of poly-based), and these are usually banners, leaflets for advertisement. There are no examples of application to MDF / PB panels due to various problems such as adhesion conditions.

In other words, the applicant's test results show that the fabric and paper printed on the MDF / PB panel are easily adhered to by general adhesives (chemical bonds), but the inner panel has a weak internal hiding force after being glued. , The photo paper has a problem that the adhesion is made as a paper material, but the outer coating finish is not possible, the synthetic resin of the poly-based resin is treated with a plyma (backlight coating coating), the air bubbles are generated when the wide surface is bonded The problem is that the surface is wrinkled.

Such wrinkles appear almost when using general adhesives when using synthetic resins, and for this reason, applicants cannot absorb adhesives in synthetic resins, which causes residual bubbles, and large adhesive panels have high early curing power. It is believed that this is due to the solidification of the adhesive in the state of not removing the remaining bubbles during the fabrication of the wide side.

Accordingly, the present invention obtains a pattern that is closer to the actual picture (photo) by the actual output, and to complete the conditions for the coating finish by adhering or adsorbing the pattern of the sheet paper or sheet paper with the pattern formed on the MDF / PB panel, It is the object of the present invention to select and to select an adhesive used therein and to make an exquisite harmony in the process of bonding them.

Therefore, the present invention is to print the pattern obtained by computer graphics on the sheet paper, and then adhere or adsorb the pattern expressed on the sheet or sheet on the MDF / PB panel surface and coat the surface to finish the process. The pattern of various patterns and colors can be obtained as in the picture of the yarn, and it is possible to manufacture a large panel according to the output of a large pattern, thereby significantly reducing the production cost of the panel and also embossing differentiated furniture And to provide a large panel for interior and exterior materials.

The large panel for furniture and interior and exterior materials and manufacturing method according to the present invention for this purpose,

In a panel in which sheet paper is bonded to the surface of an MDF / PB panel by an adhesive, the sheet paper is a laminate of a lower paper sheet and a synthetic resin of an uncoated poly system, and the laminated sheet is an adhesive to the surface of the MDF / PB panel. It is bonded using a chemical bond or silicon, characterized in that the outer surface of the paper is a pattern layer obtained by the actual output, and the outer surface of the matte or high-gloss coating layer is formed.

In addition, the silicone is characterized in that the transparent oil-based silicone without the pigment added.

Hereinafter, the structure of a large panel for furniture and interior and exterior materials according to an embodiment of the present invention with reference to the accompanying drawings in detail as follows.

<First Embodiment>

Figure 1 is an exploded view of the configuration showing a first embodiment of a large panel for furniture and interior and exterior materials according to the present invention, Figure 2 is a combination view of Figure 1, Figure 3 shows a manufacturing process diagram of Figure 1, respectively.

As shown in the drawing, the present invention is intended to give an aesthetic like a picture (picture) to the surface of the MDF / PB panel.

However, the sheet paper bonded to the existing MDF / PB panel is made of synthetic resin or general paper, and because it uses a circular copper plate when printing a pattern, it can only express a pattern of one color per copper plate and is limited in size. .

In addition, if the normal paper is adhered to the panel, it can prevent the surface wrinkles caused by the adhesive to some extent, but the inner hiding power is weak, so the pattern of the panel is exposed to the outside, and when the synthetic resin is adhered to the panel, bubbles are generated inside the adhesive surface This causes the problem of wrinkles on the surface.

Therefore, the present invention is to solve the problems as described above, the existing problem is not a simple color tone, but with a variety of patterns such as real pictures, the completion of the design capable of large output, can output the pattern and MDF / PB panel The adhesives and coatings that do not see the color of the outside without being smudged and press-squeezed finished, the adhesive that allows the sheets to be placed on the MDF / PB panel to match the picture and flow, these mutual defects By combining without the problem to solve the existing problem, and to manufacture a large panel that can lower the manufacturing process and cost as much as possible.

To this end, the present invention is configured MDF / PB panel in such a way that the sheet is bonded to the surface by the adhesive as conventional.

The paper 10 is attached to the upper surface of the MDF / PB panel 1 through the adhesive 15. In this case, the adhesive 15 may be generally used a chemical bond, but in the present invention, in consideration of the fact that the main purpose of the panel is furniture, oily silicone adhesive may be used to maximize durability so that sheet paper due to moisture does not fall. Used as.

The sheet paper is a paper (10) bonded the lower paper (11) and the synthetic resin 12 of the non-coated top, the outer surface of the paper (10) is a pattern layer 13 obtained by the actual output, and The outer surface forms a matte or high gloss coating layer 14.

In this case, the paper 10 is made of paper 11 so that the adhesive may penetrate to some extent during adhesion, thereby preventing the sheet from being wrinkled in the panel even after the adhesive is hardened. In addition, the upper side is made of a synthetic resin (12) can improve the internal concealment force, which is an existing problem, and the actual output is possible on the surface. At this time, the synthetic resin 12 means a diffuser that can raise the coating layer on the upper surface while the actual output is possible on the outer surface, the material is P.P or PE, PET is used.

The synthetic resin is a paper with good adhesion because the adhesive strength with the surface of the MDF / PB panel is considerably inferior, the upper side is a printing surface using a synthetic resin made of a durable poly material without spreading ink.

Looking at the manufacturing process of the panel as described above, as shown in Figure 3 by processing the computer graphics to complete a pattern such as a real picture in a variety of patterns and colors (S100).

At this time, the pattern of the present invention is generally output in a large size of 1 m or more in wide, thereby outputting a single image largely at a time, or by dividing along the dividing line DL as shown in FIG.

In other words, according to the part design by dividing each part surface by graphic design and then output, in the panel product completion step, each part surface of the product to be made can be formed by cutting each part surface. In this way, you can easily edit and print a variety of patterns.

Next, the finished pattern is printed on the paper 10 on the lower side and the paper 10 of the synthetic resin 12 on the lower side. (S110)

Next, spray adhesive (15, chemical bond or silicon) to the surface of the MDF / PB panel. (S120)

Toluene which is a volatile substance is added to silicon at this time, and 5-10 weight part of toluene is added with respect to 100 weight part of oil-based silicones. As a result, the silicone has a low viscosity at the time of initial adhesion, so that it is easy to attach the sheet paper, and the drying time after adhesion can accelerate the drying time because volatile toluene evaporates.

Next, the paper 10 is seated on the upper surface of the MDF / PB panel coated with a chemical bond or silicon. (S130)

When the adhesive 15 is used as a silicone having a lower initial viscosity and adhesive strength than a chemical bond, there is room for hardening time, so that the paper may be slightly moved on the panel surface to hold the pattern in place, thereby forming an internal bubble. Can be removed by hand (stroking with a tool like wallpaper).

Next, press 10 is pressed on the paper 10 seated on the MDF / PB panel (S140).

At this time, the pressing may be a thermal pressure, but if the adhesive is silicon, the adhesive surface is too thin due to heat, the adhesive force is lowered, so the cold pressure, but the cold pressure is preferably 5 to 18 ℃. After crimping | compression-bonding may be followed by the drying process by a blower.

Next, after the press pressing, the matte or high-gloss coating is performed on the upper side of the sheet paper bonded to the MDF / PB panel 1 (S160).

At this time, the matte or high-gloss coating method means that the commonly known U.V coating or poly coating.

On the other hand, the embossed layer (13a) may be further formed on the finished pattern before the matt or high light coating (S150).

At this time, the embossed layer 13a may be formed by placing a paint layer on the finished pattern in an oil painting form or by attaching a thin plate.

According to the present invention as described above, the lower side of the sheet of paper (11) and the upper side of the paper (10) of the synthetic resin 12, when the lower side of the paper (11) is absorbed to some extent and adhered to the panel surface because the adhesive It is possible to prevent the adhesive sheet from being wrinkled by bubbles and preventing the inside of the upper synthetic resin 12 from being projected.

In addition, since oil-based silicone is used as an adhesive, even when the finished product is exposed to moisture, sheet paper can be prevented from being easily separated and durability can be improved. In addition, there is an advantage that can form a surface embossing layer to further enhance the aesthetics of the product.
