Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a decorative panel in which a decorative sheet-like material is adhered to the surface of a wood fiber board as required, and cut grooves are formed therein.

(Prior art) Using a softwood fiberboard or a hardwood fiberboard as a base material, a decorative sheet-like material is attached to the surface as necessary to form cut grooves, and the inside of the cut grooves is colored and painted. Alternatively, the entire surface was coated with a top coat.

(Problem to be solved) Since a single softwood fiberboard or hardwood fiberboard is used as a base material, the color of the cut grooves on the surface is uniform. When the entire surface was top-coated, the inside of the groove was colored in a single color, and its design was poor.

If coloring were to be applied inside the grooves, it would require complicated processes using multiple painting devices, resulting in low productivity and high costs, so this is not actually done at present.

(Means for solving the problem) The base material is a composite wood fiberboard in which a plurality of softwood fiberboards 1 made of softwood wood fibers and hardwood fiberboards 2 made of hardwood wood fibers are alternately laminated and bonded. A cut groove 5 having a depth reaching at least one set of soft wood fiberboard 1 and hardwood fiberboard 2 of the plurality of laminated and bonded composite wood fiberboards is formed, and the inside of the cut groove 5 is colored. This is a decorative panel that has been painted 6.

(Function) Since the cut groove 5 reaches a depth that reaches at least the soft wood fiberboard 1 and the hard wood fiberboard 2,
The colors of light-colored hardwood and dark-colored softwood appear in layers, resulting in a decorative panel with a high degree of design.

(Explanation of Examples) A softwood fiberboard 1 molded using softwood fiber obtained by defibrating softwood materials such as cedar, cypress, hemlock, pine, fir, spruce, and cedar; , birch, china, capole, lauan, aspen, etc., are used as raw materials and hardwood fibers are molded using hardwood fibers. A plurality of wood fiberboards are laminated and bonded via an adhesive 3 to obtain a composite wood fiberboard. Each of the wood fiberboards 1 and 2 preferably has a specific gravity of 0.4 to 1, and even if the wood fiberboards have the same specific gravity, they may differ. You may also use one with specific gravity.

A decorative sheet-like material 4 such as decorative paper, decorative impregnated paper, decorative synthetic resin sheet, veneer, etc. is adhered to the surface of the obtained composite wood fiberboard via an adhesive, if necessary. Next, use a cutting machine such as a router to cut the surface.
A cutting groove 5 having a depth reaching at least one set of softwood fiberboard and hardwood fiberboard of the composite wood fiberboard is formed.

The cut grooves 5 are not limited to the surface of the composite wood fiberboard, but may be formed as chamfered grooves on the butt end surface.

Paint the inside of the cut groove in any color 6.

Also, after applying the colored coating 6, even if a top coat 7 is applied to the surface or the colored coating 6 is applied inside the cut groove.
The top coat 7 may be applied without applying.

A decorative panel was obtained as described above.

Note that FIG. 4 shows a case where a large number of softwood fiberboards 1 and hardwood fiberboards 2 are laminated.

When multiple layers of softwood and hardwood fiberboards 1 and 2 are laminated as shown in Fig. 4, multiple layers of color patterns of stripes appear within the cut grooves 5, creating a design with a rich sense of variation. .

FIG. 5 shows a case where thin hardwood fiberboards 2 are laminated above and below a thick softwood fiberboard 1.
In this case, light-colored hardwood is bordered above and below the dark-colored softwood, and the bottom, sides, and
The upper edges are each expressed with a sense of change.

(Effects of the present invention) Compared to broad-leaved wood fiberboard, softwood fiberboard is relatively bright in color and whitish, so each fiberboard is layered in the cut grooves formed in the composite wood fiberboard. The grooves appear sharp and the design inside the grooves is improved.

When the inside of the concave groove is colored or painted, the colors appear differently in each fiberboard section due to the difference in board color. In addition, by using fiberboards with different specific gravity,
Different colors can be produced due to the difference in the color of the board and the difference in suction of the paint, further improving the design.
