Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for treating wood edges of decorative boards such as ceiling boards and furniture boards.

[Background technology] Conventional methods for treating the wood edges of decorative laminates include hot-pressure bonding printed paper with a heat-sensitive adhesive, or applying adhesive to the wood edges of decorative laminates in advance and then applying natural The method of pasting wood veneer was widely known.

However, in the above method, although the former has excellent productivity, it has the disadvantage of inferior natural wood texture.
Moreover, although the latter has a sufficient natural wood texture, it has the problem of being inferior in productivity.

[Object of the Invention] The present invention has been made in view of the advantages and disadvantages of the above-mentioned conventional processing methods, and is intended to eliminate all the disadvantages while retaining the advantages.

[Structure of the invention]

The present invention involves rotary cutting or slicing of raw wood such as Agatis wood, Labra wood, Almasi wood, etc., and cutting it into a predetermined size to create a material veneer (1), and if necessary, the material veneer value) The wood is degreased, bleached, and dyed to give it the desired color of natural wood. Next, a large number of veneer sheets (values of veneers) are each bonded with ethylene vinyl acetate resin or other thermoplastic resin adhesive, or with an ethylene vinyl acetate resin sheet or other thermoplastic resin sheet. The flitches (3) are laminated and pressed from above and below with a pair of press ports (o) to form an uneven flitch (3), and the flitch (3) is sliced to a thickness of 0°. An artificial decorative veneer (4) with an i pattern of 2% to 0.5% wood is created. Next, the artificial decorative veneer (4) is brought into contact with the wood end surface (6) of the decorative board (5), and pressure is applied at a temperature of 120°C to 150°C to adhere and fix the artificial decorative veneer (4). This is a method for treating wood edges of decorative boards.

[Effects of the Invention] The present invention is configured as described above, and when the artificial decorative veneer is heat-pressed to the wood end surface of the decorative board, the thermoplastic resin contained in the artificial decorative veneer is removed. Since the adhesive layer or the thermoplastic resin sheet layer plays the role of an adhesive, the production efficiency is greatly improved, which eliminates the need for a special adhesive, and it has the effect of providing a rich woody feel.

[Brief Description of the Drawings] Figures 1 to 4 are drawings according to the present invention, in which Figure 1 is a perspective view of a material veneer, Figure 2 is a side view showing a state in which a flitch is formed, FIG. 3 is a perspective view of the artificial decorative veneer, and FIG. 4 is a perspective view of the decorative veneer. 1...
