[0001] METHOD FOR PRINTING AND COATING A WOOD PANNEL [0002]

The present invention relates to a print coating method of wood panels.

A method of performing double printing on the surface of furniture wood includes a method of performing double printing using a large printer on the surface of the primary printed furniture and a method of performing only the primary printing by designing the shape itself such as double printing have.

However, a large-sized printer is costly due to expensive equipment, and designing a shape such as a double printing is limited by various applications. Conventionally, in the development of a product, printing coating was performed using only a transfer film and a printing paper. This has caused a limitation in the design of the design due to the excessive waste of the transfer film and the printing paper, which are patterned film paper, and the technical problem of the transfer film. In addition, due to the nature of the small quantity production of various types of products, the production cost of film and printing paper for transcription has increased, and the initial cost has been increased due to the production of molds for each design.

In addition, since it takes about two weeks to one month to produce a new transfer film and printing paper, the sample work itself was impossible, and there was a difficulty in cutting the iron mold and the difficult pattern for cutting into the designed pattern.

Korean Patent No. 10-1167026 (hereafter referred to as "Prior Art") (hereinafter referred to as "Prior Art") can solve the above-described problem, but the transfer film having color and pattern formed on a wood panel is subjected to a thermal transfer process And the transfer paper on which the color and the pattern are formed on the first printed background is subjected to the second printing through the thermal transfer, so that the thermal transfer process is performed twice under different conditions. In addition, since the transfer film and the transfer paper are respectively printed and manufactured, the cost of manufacturing the mold for each design is not greatly reduced, and the inventory burden of the transfer film and the transfer paper printed respectively remain. In addition, since the secondary printing is performed partially on the background in which the primary color and the pattern are printed, there is a disadvantage that the secondary printing area covers the primary printing area.

It is an object of the present invention to provide a print coating method of a wood panel which reduces the thermal transfer processing process and reduces the stocking burden of transfer film and transfer paper.

Another object of the present invention is to provide a method of printing a wood panel in which various designs to be printed on a wood panel can be realized.

According to an aspect of the present invention, there is provided a method of manufacturing a wood panel, Applying an adhesive to the surface to be polished of the wood panel to form an adhesive film; Attaching a transparent transfer film having a translucent pattern to an adhesive film of the wood panel; And a step of thermally transferring the transparent transfer film to print a translucent pattern on the surface of the wood panel to be printed.

Also, there is provided a method of manufacturing a wood panel, comprising: polishing a surface to be printed of a wood panel; Painting a polished surface of the wood panel with a water-based paint; Applying an adhesive to a painted surface of the wood panel to form an adhesive film; Attaching a transparent transfer film having a translucent pattern to an adhesive film of the wood panel; And a step of thermally transferring the transparent transfer film to print a translucent pattern on a painted surface.

Forming an engraved portion and an embossed portion on a surface to be printed of the wood panel; Polishing the surface to be printed on which the engraved and raised portions of the wood panel are formed; Painting an engraved portion of the surface to be printed with an aqueous paint; Applying an adhesive to a surface to be printed of the wood panel to form an adhesive film; Attaching a transparent transfer film having a translucent pattern to an adhesive film of the wood panel; And a step of thermally transferring the transparent transfer film to print a translucent pattern on the surface of the object to be printed.

Attaching an auxiliary member to a surface to be printed of the wood panel; Polishing the surface to be printed including the auxiliary member; Applying an adhesive to a surface to be printed of the wood panel to form an adhesive film; Attaching a transparent transfer film having a translucent pattern to an adhesive film of the wood panel; And a step of thermally transferring the transparent transfer film to print a translucent pattern on the surface of the object to be printed.

Preferably, the wood panel is an MDF panel.

The transparent transfer film preferably includes a release paper which is a translucent synthetic resin film and a translucent pattern printed on the release paper.

The semitransparent pattern of the transparent transfer film is preferably a grain shape.

The present invention is characterized in that a translucent pattern printed on a surface of a wood panel to be printed with a water-based paint and a translucent pattern (or transparent) printed on a painted background is subjected to a thermal transfer process to print a translucent pattern on the background, And the design of various forms can be realized. Since a translucent grain pattern is printed on the oak-colored painted surface as in the specific embodiment, the same design as the wood can be realized. This way, new designs can be implemented with colored backgrounds and additional printed translucent patterns, enabling various designs on wood panels.

In addition, the present invention can reduce the thermal transfer process because the wood panel is printed with a water-based paint and the translucent transfer film having a translucent pattern formed on the painted background is thermally transferred to the wood panel. Since the transparent transfer film is used, the amount of the transfer material to be printed in advance is small, which can reduce the burden on the stock and reduce the burden on the production of the mold. In particular, when a transparent transfer film is immediately transferred to a wood panel by thermal transfer treatment, the use of a water-based coating material can be excluded to reduce material costs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a print coating method of a wood panel according to the present invention will be described with reference to the accompanying drawings.

1 is a flow chart showing a first embodiment of a print coating method of a wood panel according to the present invention.

As shown in FIG. 1, a first embodiment of a print coating method of a wood panel according to the present invention comprises a step (S10) of cutting a raw material to produce a wood panel and then polishing a surface to be printed of the wood panel, . Preferably, the wood panel is a Medium Density Fiberboard Panel. As is well known, the MDF panel is made by pulverizing wood into a fibrous state and then pressing it with an adhesive such as a resin. The wooden panel is made of the shape and the size set by processing the wood of the MC lath etc. by the pneumatic system.

A step S20 of painting a water-based paint on the surface to be polished of the wood panel proceeds. Water-based paints can be used in various colors of water-based paints.

A step (S30) of applying an adhesive to the surface of the wood panel to be printed is proceeded. That is, an adhesive is applied to the painted surface to be printed to form an adhesive film. The adhesive film is transparent. The adhesive is preferably an aqueous adhesive. The adhesive film is allowed to dry naturally at room temperature for 30 to 60 minutes.

After the adhesive film applied to the wood panel is dried, a step S40 of attaching a transparent transfer film having a translucent pattern to the adhesive film of the wood panel is performed. The transparent transfer film preferably includes a release paper which is a transparent synthetic resin film and a translucent pattern printed on the release paper. The translucent pattern printed on the release paper is preferably in the form of a grain. A translucent pattern can be a polygonal shape or a figure. A transparent transfer film is attached to the surface of the wood panel to be printed so that the printed surface of the translucent pattern is brought into contact with the adhesive film.

When the attachment of the transparent transfer film is completed, the transparent transfer film is thermally transferred using a thermal press to perform a step S50 of printing a translucent pattern on the painted surface. The setting of the thermal press machine is preferably carried out under the conditions of a pressure of 1.5 to 3 kg / cm ² , a time of 80 to 120 seconds, and a temperature of 150 to 190 ° C. When the thermal transfer process is completed, the release paper of the transparent transfer film is peeled off. When the transparent transfer film is thermally transferred, the translucent pattern of the transparent transfer film is transferred to the surface of the printed object together with the adhesive layer, and a translucent pattern is printed on the painted color background. For example, if the painted color is oak and the translucent pattern is a grain pattern, a translucent grain pattern is printed on the oak and printed like a log.

After the translucent pattern is transferred, a step of forming a transparent protective coating film for protecting the translucent pattern is performed. The protective coating film is formed by applying a coating liquid to a surface of a printing object, drying the surface, processing the surface, and applying a top coating. The coating liquid is a mixture of a liquid urethane, a curing agent, and a thinner at a ratio of 3: 1: 1. The coating liquid is sprayed on the surface of a printing object to be sprayed, and the drying is preferably naturally dried at 30 ° C for 2 hours.

The process of painting an aqueous paint is the same as that described in the first embodiment.

Hereinafter, the operation and effect of the print coating method of the wood panel according to the present invention will be described.

Since the translucent transfer film on which a translucent pattern is printed on a painted background painted with water-based paint on a surface to be printed of a wood panel is subjected to a thermal transfer process, a translucent pattern is printed on the background, so that a combination of a background background and an additional translucent pattern Not only can a design be implemented well but various types of designs can be implemented. Since a translucent grain pattern is printed on the oak-colored painted surface as in the specific embodiment, the same design as the wood can be realized. This way, new designs can be implemented with colored backgrounds and additional printed translucent patterns, enabling various designs on wood panels. In addition, when a wood panel is formed by embossing and embossing on the surface to be printed and painted with water-based paint only on the engraved portion, and then a transparent transfer film having a translucent pattern is thermally transferred, the shade design can be clearly expressed on the surface When the auxiliary member is attached to the wood panel and the transparent transfer film is subjected to the transfer process, various designs can be expressed.

In addition, the present invention can reduce the thermal transfer process because the wood panel is printed with a water-based paint and the translucent transfer film having a translucent pattern formed on the painted background is thermally transferred to the wood panel. Since the transparent transfer film is used, the amount of the transfer material to be printed in advance is small, which can reduce the burden on the stock and reduce the burden on the production of the mold. In particular, when a transparent transfer film is immediately transferred to a wood panel by thermal transfer treatment, the use of a water-based coating material can be excluded to reduce material costs.
