Description

[Detailed description of the invention] This invention relates to a method for manufacturing decorative veneers.

A composite flitch is obtained by laminating and press-bonding multiple veneers of material using an adhesive, and this composite flitch is sliced from a predetermined direction that intersects with the laminated surface, and the wood grain is measured on the cut surface of each material veneer. In the method for obtaining a laminated decorative veneer that expresses a pattern, when expressing a relatively wide summer wood part in the wood grain pattern to be reproduced, it is necessary to add a layer of summer wood colored between the laminated material veneers for expressing spring wood. The conventional method was to sandwich 9 pieces of veneer paper, 9 pieces of plastic film, etc. to form an assembled flitch, and then express the summer wood part with the cut surfaces of these 2 pieces of colored veneer paper, glass film, etc.

However, with this method, not only does the color tone of the reproduced summer wood become hokey, but also no change in width is imparted. It has the disadvantage that it is not possible to faithfully express wood grain patterns that vary in color within one layer of the material.

Accordingly, an object of the present invention is to provide a method for manufacturing decorative veneer that can faithfully reproduce the waste wood parts that have color changes and width changes such as those found in naturally fertilized pine.

An embodiment of the present invention is shown in the drawings (Al to fJ+). That is, this decorative veneer manufacturing method is to obtain a laminated decorative veneer having a wood grain pattern resembling natural fertilized pine through the following steps.

(1) After degreasing and decolorizing a wooden material veneer 1 obtained by slicing (slice thickness: 0.2 to 0.6 mm) from a tree species with a wide summer wood part (in this example, Japanese pine), the car material color was determined. Boiling dyeing is carried out in a dyeing bath 2 to obtain a summer wood color dyed veneer 3 (Figures (N to (C)).

(2) The summer wood color-dyed veneer 3 is sandwiched between elastic facing materials 4.4 such as rubber, and the summer wood color-dyed veneer 3 is compressed through the elastic facing materials 4.4 to form a natural summer wood color. A textured veneer 3' is obtained in which the surface region 3'a corresponding to the natural spring material part, which is softer than the surface region 3'b corresponding to the material part, is selectively compressed (FIG. (IX(E)).

(3) Slice (slice thickness 0.s to 1,6
mm) The wood material veneers 1' obtained by the process are boiled and dyed in a dyeing bath 2' of the test material color to obtain a spring wood color dyed veneer 5 (Figure (Fl. (G)).

(4) The textured veneer 3' and the spring wood color-dyed veneer 5 are alternately laminated with an adhesive and bonded by pressure using a texture mold 6 to obtain a textured laminated flitch 7 (Figure () 1). ).

(5) The unevenness laminated flitch 7'tl - sliced from a predetermined direction intersecting the laminated surface thereof, and the summer wood portion 8b and the spring wood color-dyed veneer represented by the cut surface of the unevenness treated veneer 3'. A laminated decorative veneer 8 is obtained in which the spring wood portions 8a expressed by the cut surfaces of 5 alternate in a board pattern (Figure (J)).

In this way, as a material veneer for summer wood, the material veneer 1 is dyed in the color of summer wood on wood obtained from a tree species having a wide summer wood part, and this dyed veneer 3 is treated with an elastic facing material 4. Since the surface area 3'a corresponding to the natural spring wood part is selectively compressed by pinching to make the unevenness treated veneer 3', the summer wood part 1b of the wood material veneer 1 and the spring Due to the difference in the staining intensity of the wood portion 1a (the hard summer wood portion 1b has a lower dyeing intensity than the soft spring wood portion 1a), uneven dyeing occurs in the reproduced spring wood portion 8b based on the difference in dyeing intensity. This makes it possible to express the color change of the summer wood part, and furthermore, the width change occurs in the summer wood part 8b reproduced by the unevenness treatment applied to the surface of the summer wood color-dyed veneer 30, and the width change and color change occur. It is possible to faithfully reproduce the summer wood part that resembles naturally fertilized pine, and it is possible to impart a wood grain pattern with a rich natural feel.

In addition, wood material veneer 1 obtained from tree species with wide summer wood
In the summer wood portion 8b made of wood, the natural summer wood portion 1b is dispersed and exposed, so the natural summer wood portion 1b imparts a change in gloss, making it possible to reproduce a wood grain pattern with a more natural feel. .

In addition, wood material veneer 1' used to express the spring wood part.
The spring wood color dyed veneer 5 is in contact with the unevenness-treated veneer 3' for expressing the summer wood area, which has an indistinct summer wood area and has a soft wood quality.
can be made to closely follow the uneven surface of the uneven-treated veneer 3'.

The uneven shade of the summer wood color-dyed veneer 3 is caused by dyeing the summer wood color in a lighter color compared to the summer wood portion 1b of the wood material veneer 1, which is the material of the summer wood color dyed veneer 3. , natural summer wood part 1b
The surface area corresponding to the natural spring wood portion 1a is dyed in a dark color, and the surface area corresponding to the natural spring wood portion 1a is dyed in a light color (5). When color dyeing is applied, the area corresponding to the natural spring wood part 1a will be dyed in a darker color than the natural summer wood part 1b, and the shading of the uneven dyeing corresponds to the natural spring wood part 1as and the summer wood part 1b. is not necessarily uniform.

As described above, the method for producing a decorative veneer of the present invention involves selectively pressing the summer wood material veneer made of a tree species with a wide summer wood portion with an elastic pressing surface material to selectively remove the surface area corresponding to the spring wood portion. An unevenness treatment process to obtain an unevenly treated veneer for summer wood compressed into a veneer, and a gluing process in which the material heavy board for spring wood and the uneven treated veneer for summer wood are combined and laminated and pressed together using an adhesive to obtain a composite flitch. Since it includes a flitch forming step and a slicing step of slicing the assembled flitch in a predetermined direction that intersects with the laminated surface thereof, it is possible to impart color tone change, zero width change, and gloss change to the summer wood portion of the wood grain pattern to be reproduced. It has the effect of faithfully expressing the summer wood part found in naturally fertilized pine, and making it possible to create a decorative veneer with a rich natural feel.
