Metal panel laminated with functional veneer {METALLIC PANEL WITH A FUNCTIONAL VENEER}

The present invention relates to a panel in which a sheet of semi-transparent decorative film, in which high-quality veneer patterns are printed on a low-cost veneer, is bonded to a metal plate such as steel or aluminum, and more specifically, a low-cost veneer By joining the decorative film with the high-quality veneer pattern printed on the upper surface and attaching it to the metal plate such as steel or aluminum, the soft texture of the high-quality veneer pattern and the natural material It relates to a metal panel bonded with functional veneer sheets that simultaneously express aesthetics. The veneer can be characterized by the shape, number and pattern of the rings, and in general, the low-cost veneer is made up of tropical hardwood species and has very few rings. The pattern is inconsistent and the mechanical properties of the species are weak. There is a lot of loss. On the other hand, expensive veneers are temperate coniferous trees with a beautiful surface, a large number of rings, distinctive patterns, and strong mechanical strength.

As living standards improve and household appliances such as washing machines, dishwashers and refrigerators in newly sold apartments are built-in, harmony with kitchen furniture and other furniture becomes an important issue. Therefore, various methods are used to give the exterior material of home appliances similar to the furniture material.

Firstly, the method of printing the wood pattern on the material used as the housing of the home appliance,

Secondly, the method of adhering the wood-like decor sheet onto the material used as the housing of the household appliance,

Third, a method of bonding high quality natural veneer onto a material and painting is used.

However, the above methods have the following disadvantages,

The method of printing a wood pattern on a metal plate has a disadvantage in that the perfect implementation of the pattern is difficult depending on the printing method, and in particular, the implementation of a straight and uniform grain pattern (straight grain) is difficult.

In addition, the method of adhering the opaque deco sheet printed with the wood pattern has developed a lot of printing technology, but there is a fundamental limitation to implement all the feeling of natural wood. Therefore, after the high-quality natural veneer veneer as a way to best realize the feeling of natural wood, the method of painting is used, this method has the disadvantages such as depletion of natural materials and the resulting increase in price.

In this way, a low-cost natural veneer is bonded on a metal plate using adhesive, and a translucent deco-film with expensive high-quality natural veneer pattern is printed on the upper surface, thereby making it possible to use high-quality materials at a low price while maintaining the feel of natural materials. Can provide.

Therefore, the present invention aims to solve these problems of the prior art and technical problems that have been requested from the past.

That is, for the purpose of the present invention, in addition to the texture and dignity of high-quality veneer, in addition to the texture and dignity of the high-quality veneer, a functional coating layer such as antibacterial, fragrance, stain resistance, and scratch resistance is provided to provide a veneer laminated metal panel that combines functionality. will be.

The veneer laminated metal panel according to the present invention for achieving the above object, the adhesive is applied to the surface of the metal plate such as steel (Steel) and aluminum, and the low-cost veneer on the adhesive surface surface at 50 to 80 ℃ at a pressure of 70 to 100 atm Adhesion is carried out by thermocompression at a temperature of, and the adhesive film is applied again to the veneer layer to adhere the decor film under the above conditions. The deco film layer is made of a translucent state in which a high-quality veneer pattern is printed.

Accordingly, the veneer laminated metal panel of the present invention bonds a functional veneer sheet to the upper surface of steel or aluminum so that the wood texture of the low-cost veneer layer at the bottom is expressed through the translucent decor film and printed on the decor film layer. The high-quality veneer pattern is combined with the texture of the natural wood, thereby exerting the same effect as the veneer laminated panel made up of the high-quality veneer layer as a whole.

The thickness of the steel or aluminum panel is not particularly limited as long as it can constitute a plate-shaped panel, but a thickness of usually within 0.1 to 5 mm is preferable. The thickness of the low-cost veneer layer and the thickness of the deco film layer are not particularly limited as long as they can constitute the veneer sheet. The thickness of the low-cost veneer layer is 0.05 to 1.5 mm, preferably 0.2 to 0.6 mm, and the thickness of the decor film layer is 0.05 to 0.5 mm, preferably 0.1 to 0.2 mm. If the thickness of the low-cost veneer layer is too thin, it is difficult to express the texture unique to the tree, and if it is too thick, the yield of the veneer itself decreases, which is not preferable because the price increases. In addition, if the thickness of the decor film layer is too thin, it is easy to be torn during the manufacturing process or the use of the final sheet, on the contrary, if too thick, the texture of the wood is likely to be damaged, which is not preferable.

In some cases, the upper surface of the decor film layer may further include a functional coating layer. The functional coating layer may be a coating layer having one or more functions selected from antibacterial, fragrance, stain resistance, scratch resistance and the like.

The present invention also relates to a housing of household appliances such as a refrigerator, a washing machine, a microwave oven, an air cleaner, and the like, such as a surface material of a steel furniture, a fire door, a partition wall, and the like, which are manufactured using a metal panel bonded with veneer.

In order to express the high-quality texture and dignity using the prior art, expensive veneer should be used, and painting is required for surface protection. Therefore, the present invention solves all of these problems as can be seen in the following description with reference to the drawings. However, the following description and reference drawings are intended to illustrate preferred examples of the present invention, and the law of the present invention is limited thereto.

1 is a cross-sectional configuration of a veneer metal panel according to an embodiment of the present invention.

The veneer laminated metal panel 10 of FIG. 1 includes an adhesive layer 30, an inexpensive veneer layer 40, an adhesive layer 50, a decorative film layer 60, on a steel or an upper surface of an aluminum sheet 20. The functional coating layer 70 is sequentially located. Among them, the configurations of the adhesive layer 30 and the veneer layer 40 are the same as in the conventional veneer laminated panel.

The adhesives 30 and 50 are not particularly limited as long as they bond the upper and lower constituent layers. Preferably, the adhesive layers of the veneer sheet and the metal sheet are epoxy or polyurethane-based adhesives, and the low-cost veneer layer 40 As the adhesive agent layer 50 of the decor film layer 60, ethylene vinyl acetate (EVA) adhesive is preferably used.

The low-cost veneer layer 40 is obtained as a relatively low-cost tropical timber wood compared to the timber of temperate wood, such as Chenchen, Nawang, Meranti, Sappele and the like.

An expensive veneer pattern is printed on the deco film layer 60. As its base film, for example, polyolefin resin such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl fluoride and polyester-based Resins can be used. The high-priced veneer pattern means a pattern of a timber of temperate timber, but is not limited thereto, and may be a rather artificial pattern that can exhibit more superior texture and dignity based on the pattern of such timber of timber. The printing of veneer patterns on deco film is a type of intaglio printing, which can be done through gravure printing, which reproduces colors smoothly. The top surface of the deco film layer 60 may be subjected to a separate post treatment to provide an excellent surface feel, for example, fine etching or sand blasting to provide a natural touch such as a cross section of wood. I can do it.

The topmost functional coating layer 70 is an optional layer that can be optionally added, for example, by coating nano ceramics, such as montmorillonite (MMT), to increase the surface strength. Alternatively, titanium dioxide, aluminum oxide, or the like is sprayed onto an ultraviolet curable resin, for example, a polyurethane acrylate resin or a polyester resin, and then sprayed or impregnated onto the decor film layer 60, followed by ultraviolet curing to coat the coating layer. By forming the above, it is possible to improve the strength, and to improve the stain resistance. In some cases, when functional ingredients such as aromatic substances and antimicrobial agents are added to the coating layer material in an amount of 2 to 10% based on the total weight of the coating layer, functional veneer having aromatic characteristics and antibacterial properties can be prepared. When the aromatic substance is added below the content, the function is insufficient. When the aromatic substance is added above the content, the unit price increase ratio becomes higher than the functional property.

2 is a process diagram for improving a metal panel bonded functional veneer according to the present invention. First sort by low-cost veneer color or wood (wood grain), and then cut with guillotine. In this way, the low-cost veneer is cut by color, wood, etc. There are two methods, the F / L Innovation, and the splicing method of zigzag bonding. The side-cut veneer is coated with an epoxy or polyurethane-based adhesive on a metal panel such as steel or aluminum, and then adhered using a press. Thereafter, the surface is polished using equipment such as a belt sander, and the decor film is laminated or the functional coating is performed after the lamination step.

Although the contents of the present invention have been described above, those of ordinary skill in the art will be able to perform various applications and modifications within the scope of the present invention based on the above contents.

According to the present invention, a high-quality veneer pattern printed on top of a low-cost veneer is bonded to a steel (Steel) or aluminum plate to produce a panel, using a low-cost veneer using the dignity and beauty of high-quality veneer The veneer laminated metal panel can be manufactured at a low price, and by forming a functional coating layer, it is possible to manufacture a functional veneer laminated metal panel having antibacterial, fragrance, stain resistance, and scratch resistance.

It is possible to provide a functional veneer laminated metal panel having a sense of high quality veneer at a relatively low price while satisfying the desire for high quality of the consumer. The functional veneer laminated metal panel manufactured in this way is a refrigerator, a washing machine, a microwave oven, an air purifier, etc. It can be used as high-end wall finishing materials such as housing of home appliances, surface material of steel furniture, fire door, partition wall, etc.
