[Detailed description of the invention] [Industrial application field] The present invention relates to a door decorative panel and a manufacturing method thereof.

[Conventional technology]

In general, decorative boards include veneer O'Hurley plywood, plastic O'Hurley plywood, paper O'Hurley plywood, cloth O'Hurley plywood, heart-hode O'Hurley plywood, etc.
Veneer O-Hurley plywood is ordinary plywood (made by laminating veneers and not subjected to any secondary processing) with the beautiful grain of natural wood, or 7.V cut from precious wood. Plastic O'Hurley plywood is a plywood whose surface is coated with O'Hurley resin film, impregnated paper, or plastic laminate. Moreover, paper-overlay plywood is made by overlaying patterned paper, etc., and cloth-overlay plywood is made by overlaying cloth.

[Problem to be solved by the invention]

Therefore, the surface of the above-mentioned decorative board is flat, and the decorative board cannot be applied to a high-grade flush door having an uneven portion.

In addition, if an uneven surface is to be formed on these decorative laminates, it is necessary to provide an uneven surface on the front surface of a flat substrate and then cover the surface with a thin decorative veneer, making the manufacturing process cumbersome. and
Furthermore, the overall thickness of the substrate must be increased to accommodate the four portions of the uneven portions, resulting in a large amount of wasted portions and increased costs.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a decorative panel for a door that can be manufactured easily and at low cost, and that can provide a luxurious feel by forming an uneven surface on the surface, and a method for manufacturing the same. purpose.

[Means to solve the problem]

It is. In addition, the method for manufacturing a decorative board for a door according to the present invention includes forming a thick part by partially pasting and tearing off an air permeable abutting part on the back side of an air permeable flat plate body, and then A recess is formed in the thick part by cutting the surface of the flat plate from the part corresponding to the contact member, the surface is made into an uneven surface, and then a pre-heated thermoplastic film-like material is
After covering the surface with the table shown in (h) or covering the surface with an unheated thermoplastic film-like material, heat the film-like material, and then cover the surface with the surface side of the film-like material. to bring the film-like body into close contact with the surface.

[Effect]

In the decorative board according to the present invention, since the film-like body is in close contact with the uneven surface of the substrate, a convex gate surface is formed on the surface of the decorative board, and moreover, the thick part Since a recess is formed in the flat plate and the front surface of the flat plate becomes an uneven surface, there is no need to increase the thickness of the flat plate other than the thick portion. Moreover, since the front surface of the flat plate body is covered with a film-like material, there is no need to change the flat plate body and the contact portion to high-quality materials.

Further, according to the method for manufacturing a decorative board according to the present invention, the thick portion in which the recess is formed can be formed by partially bonding the backing member to the back surface of the flat plate, and If the film-like body is sucked toward the surface, the film-like body is easily and reliably attracted, and a decorative board is formed, since both the flat plate body and the backing member have air permeability.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 2 shows a decorative board according to the present invention. As shown in FIG. Closely attached film-like body 4
The substrate 3 consists of a flat plate body 1 and a contact portion 5 partially stretched (bonded) on the back surface 1b of the flat plate body 1. A thick wall portion 6 is formed in the area.

A recess 7 that opens toward the front surface 1a of the flat plate body 1 is provided in the thick portion 6, and the front surface 1a is a gate ++1+ surface.

Therefore, as shown in FIG.
A plurality of rectangular ring-shaped four parts 8 are formed. In other words,
The front surface S other than the concave portion 8 becomes a convex portion 9, and this front surface S
is considered to be an uneven surface.

Here, the flat plate body 1 and the contact part shrine 5 are a henia plate,
The film-like body 4 is made of a material having air permeability such as particle board or woven fiber (MDF) board, and the film-like body 4 is made of a thermoplastic synthetic resin such as vinyl chloride. It is set to 0.1 to 0.3 mm.

Next, a method for manufacturing a decorative board constructed as described above will be explained.

First, as shown in FIG. 4, on the back surface 1b of the flat plate body 1, the thick portions 6 are formed by partially bonding the abutting portions 5. In this case, the abutment member 5 is placed at the place where the recess 8 is to be provided! In this example,
As shown in FIG. 3, they may be pasted together in a ladder shape.

Next, a recess 7 as shown in FIG. 5 is formed in the thick part 6 from the contact member corresponding part 10 of the front surface 1a of the flat plate 1 using a cutting machine such as a rook, and the recess 7 as shown in FIG. A substrate 3 having an uneven surface is formed. Since this recess 7 is covered with the film-like body 4 to form four parts 8, it is assumed to have a rectangular ring shape as shown in FIG. 2, and the opening side is gradually enlarged. .

Then, as shown in FIG. 6, this substrate 3 is placed on the receiving plate 11, and the film-like body 4 is exposed and placed on the la. Next, from this state, the film-like body 4 is exposed to face 1a.
In this case, the front surface 1 is
An adhesive is applied to the back surface of a and/or the film-like body 6. Here, the vacuum device 12 includes a wooden body 13 that receives the receiving plate 11, and a vacuum pump (not shown), and the main body 13 has a recess 14, and the recess I4 A communicating hole 15 is connected to the connecting hole 15 . A vacuum pump (not shown) is connected to this communication hole 15, and when suction is performed by this vacuum pump as shown by the arrow, a vacuum chamber 17 formed by the recess 14 and the back surface 16 of the receiving plate 11 is brought into a vacuum state. It is said that Moreover, a large number of communication passages 18... are provided in the receiving plate 1l.

Therefore, when the vacuum chamber 17 is brought into a vacuum state, the film-like body 4 is attracted to the front surface 1a since both the flat plate 1 and the backing member 5 have air permeability.

Therefore, in this case, the end 19 of the fill J and the shaped body 4 is
It is pressed and sealed with the presser lid 20. That is, this presser lid 20 consists of an upper wall 2I and a side wall 22.
The lower edge 23 of the film presses the end 19 of the film-like body 4, and is opened and closed by reciprocating as shown by the arrow by a cylinder mechanism 24. In addition, a through hole 25 is provided in the -L wall 21, hot air etc. is sent through the through hole 25, the inside of the lid 20 is a pressure chamber 26, and the fill l and the shaped body 4 are exposed as shown by the arrows. 1a
Pressed to the side.

Therefore, when hot air is sent into the lid 20, the film-like body 4 is heated and easily deformed.Moreover, if the vacuum chamber 13 is brought into a vacuum state in this state, this film 7J and the film-like body 4 will have a pressure chamber. The pressing force in the direction of the arrow 26 and the suction force toward the front surface 1a of the vacuum chamber 17 act, and the l-th
As shown in the figure, the fill 1 and the shaped body 4 are reliably exposed and adhered to the surface 1a without any gaps. In addition, if the film-like body 4 is made to have thermal adhesive properties, the film-like body 4 can be brought into close contact with the facing surface 1a by heating without using an adhesive.

Moreover, if the air sent into the lid 20 is not hot air, the film J and the film 4 may be heated in advance before the film 4 is exposed and placed on the surface 1a. The heating temperature is also said to be around 150°C.

Thus, two decorative boards constructed as described above are pasted together to form a toa. That is, two Ff boards are arranged back to back so that the back surfaces of the substrates 3 face each other, and a core material is interposed between the decorative boards to bond and integrate the decorative boards. This forms the door. Therefore, the finished door does not suffer from problems such as "the first part breaks" and "there is a gap at the joint."

It is Il1l. In other words, the depth, shape, position, etc. of the recess 8 formed on the surface S of the decorative board are free, and the surface S
The uneven shape can be freely set. In addition, the film-like body 4
It is also possible to apply a surface treatment such as an embossed pattern when the substrate is in close contact with the facing surface 1a and is in a heated state. Specifically, the rollers, etc., are engraved with imitations of each kon.
It is pressed onto the surface of the film-like body 4. In addition to the embossed pattern, it is also possible to process the surface of the film-like body 4 into a mirror shape.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

Since the contact part shrine 5 is attached to the back 1b of the flat plate body 1, it is not necessary to attach the position with high precision, and it can be attached relatively roughly, and the work is easy. Moreover, this decorative board can be manufactured by forming the four places 7 on the thick part 6 and covering it with the film-like body 4, so it is simple and inexpensive without requiring any advanced technology. Decorative boards can be manufactured. Furthermore, since the flat plate body 1 and the contact portion 5 are not exposed to the outside, there is no need to make them of A quality. In addition, specifically, the cosmetic mask of the present invention has approximately 1
/2, and the manufacturing time was reduced to about 1/3.

In addition, since the substrate 3 does not need to have a 1°I dimension larger than the thick portion 6, there is no need to increase the thickness of the flat plate 1, and a large amount of material can be omitted. , the overall weight is reduced and the cost is not increased.

Moreover, since the manufactured decorative board film-like body 4 is heated and pressurized, the length of time is increased.

Furthermore, this decorative board can have an uneven surface and a divine pattern on the surface S, and although it is manufactured at a low cost,
It gives you a luxurious feel.
