Description

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

A composite flitch is obtained by laminating multiple veneers of the material using an adhesive, pressing and bonding them together, and slicing the composite flitch from a predetermined direction that intersects the laminated surface to create a natural veneer on the cut surface of each material veneer. One way to obtain a decorative veneer that expresses the annual ring layers seen in wood is to express the wide summer wood area similar to coniferous trees such as pine in the expressed wood grain pattern. The board (which became the spring material) was combined with different materials such as paper, nonwoven fabric, and veneer.

However, although partial printing is used for paper, non-woven fabrics, etc. to express the color unevenness seen in large areas of summer wood such as pine, there has been no effective method for expressing color unevenness for veneer. .

Therefore, it is an object of the present invention to have a wide width of the summerwood portions to be expressed and between and within the summerwood portions.

An embodiment of the present invention will be explained based on FIG. A plurality of boards 1 are placed one on top of the other, with a thin plastic film 2 partially interposed between each veneer, and placed in a basket 3, and immersed in a dyeing solution 4 to dye the summerwood color with uneven coloring. After that, it is dried to adjust the moisture content to a predetermined value, and is pasted onto the material veneer 5 for expressing the spring material and the composite veneer 6 through an adhesive bar IJ.
f: A plurality of sheets of this four-ply veneer 6 are laminated in a concave-convex mold 7 using a cementing agent, and then pressed and cemented to obtain a prelith 8, which is then spun to obtain a decorative veneer 9. It is something.

The material veneers 1 for expressing the summer wood part are stacked in groups of 3 to 5 at a time, and placed in a mesh-like space 1°. ,
Form into iT@ stage. Further, a plastifilm 2 having a thickness of about 10 μm is partially interposed between each veneer. The raw material veneer 1 placed in the basket 3 is pressed down from above so that it does not move, and is immersed in a dyeing solution 4 to be dyed. In this way, among the stacked small veneers 1 shown in Figure 1 (A+), the middle veneer was dyed lighter than the veneers on both sides, and the plastic film 2 inserted between the veneers The parts are dark and the curved parts are dyed darkly, which can cause uneven coloring between the veneers and within the platelets.

The material medium board 1 on which color unevenness has been formed in this way is pasted with the material veneer 5 for expressing spring material in such a way that the dark colored part is ISSi 2 of the summer wood part, and is made into a laminated material/Jchi. This is sliced by 1. The decorative raw board 9 obtained by this process can have a summer wood part 11 with a wide width and hD et al.

As described above, the ψ-curved convex method of the decorative inner plate of the present invention is to apply the colored liquid impermeable film J- partially to the ↑ pillars while fully overlapping the layers of the inner plate. A sheep immersed in 3 liquids (-7 νr et σ) is shown on a formula-like beam.
By including it, the width of the summer wood area is wide, and color unevenness can be expressed in the +1 area and inside the summer wood area, which has the Q'll benefit of being extremely natural.

Next, we will explain the production method of decorative small boards whose summer wood parts are similar to those of dog-grown wood (see 7).

In other words, decorative small plates are generally made by combining a single plate of material such as a rotary middle plate or a sliced plate with a different material P+ to express the summer dipper part and reusing it by turning it into a plywood (7, ? knee j1.', r switch). -〇- However, the expression of the hardness and luster of the summer wood was insufficient compared to the Natural God type 1.

Therefore, as shown in Fig. 2 (Δ1 to Ill), J
The material veneer 12 is treated with alkaline acid 13 as a material for expressing the material part.
For example, in a 10% solution of NflOH at 40"C for 30
After cleaning and draining the water, it was immersed in benzene chloride solution 14 at 100 to 150''C for 3 hours, and if necessary, it was immersed in blue diarrhea 15 to achieve the desired color. (Using boards, alternately combining them with Harumura # timber boards 16 and cutting the grout between the small boards] 7, press and engrave with the uneven mold 17, assembled yellowtail 1

After slicing Buri Tsuchi 18 to a thickness of approximately 0.3 mm, the resulting sliced veneer 19 was heated at 170 ''C for 10 minutes.

From Sho Tsuku 1 to 1, the hardness has increased compared to the middle board 16 used for the cutting section, and it now emits a luster that closely resembles that of natural summer wood, and the decorative middle board is not Natural-looking book uploaded
The school is also finished.

In addition, after making a fringe using only the small board 12 treated for the summer wood section and slicing it, 170"
When the heat treatment is performed for 10 minutes at 1000 yen, the entire sliced veneer 19 can be finished in a surface-strengthened shape.

Next, a test example will be given and C will be explained in more detail.
