More particularly, the present invention relates to a wood foil capable of manufacturing a product only by thermal press and insert injection, thereby minimizing the cost and reducing the cost, a method of manufacturing the wood foil, a method of manufacturing the wood foil, To a molded article which is used.

BACKGROUND ART [0002] In general, resin molded parts such as a console box of an automobile or a panel around an instrument panel are widely used as interior and exterior materials for automobiles, and resin molded articles are widely used for household appliances such as cases and covers for electronic rice cookers.

In particular, various control devices and convenience devices are installed in a dash board, an audio deck, a gear shift portion, an airbag, a door lock, and a window opening / closing portion mounted around a driver's seat and a passenger seat of a vehicle. An interior finishing panel is installed in the gap between the exterior of the apparatus and the interior material to finish the interior material, and such a finishing panel is an important factor for determining the appearance of the interior of the vehicle.

As such, the automobile finishing panel has a considerable influence on the aesthetics inside the automobile, and thus the aesthetic demands of the automobile are becoming increasingly apparent in the current trend of personalization of the automobile.

Accordingly, in recent years, there has been an increasing demand for interior materials made of real products such as real woods in order to obtain a sophisticated appearance and a high quality of appearance.

As a conventional method for manufacturing a finished panel using a real wood as an interior material, according to a conventional laminate method, a base material to be coated with wood is first laid on a base layer, real wood is applied thereon, And the surface is coated / polished.

However, in the conventional laminate method, there is a problem in that the surface coating is manually repeated 6 to 7 times to make the surface glossy and the manufacturing cost is high.

In addition, it is also possible to use an encapsulation method in which real wood is adhered to a base material, then the base material is inserted into a separate molding machine and the coating agent is injected into the molding machine and the finished product is taken out at one time, and an encapsulation method using a thermosetting resin However, since the real wood containing a lot of bubbles is attached directly to the substrate, voids are generated and the product is likely to be defective due to voids between the coating material and the real material due to air bubbles and voids. There was a problem that it was not good.

In addition, when the interior material is produced by the autoclave method using a thermosetting resin, the process is complicated due to the curing conditions of the thermosetting base layer and the like, and the manufacturing cost of the final product is high. In addition, It is difficult to install the interior material with an adhesive such as an adhesive tape and the like so that the interior material is difficult to install and the assembly is liable to be defective.
