Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.

A plurality of material veneers coated with adhesive are laminated, and these are pressed and bonded using a concave-convex die to obtain a concave-convex deformed flitch, and this deformed flitch is sliced from a predetermined direction to determine the lamination boundary of each of the material veneers. In the conventional manufacturing method of artificially decorated veneer, which expresses a wood grain pattern that resembles tree-ring lines on the wood surface, conduit holes appear along the circular mounds of tree-ring lines, such as in hardwoods such as chestnut and zelkova. It was not possible to express the ring pore material.

Therefore, an object of the present invention is to provide a method for manufacturing an artificial decorative veneer that can express a material surface that closely resembles that of natural ring-pored material.

An overview of this invention is shown in FIGS. 1A to 1G.

That is, as shown in FIG. 1A, this artificial decorative veneer manufacturing method involves applying raw wood to the surface of a material veneer 1 with a thickness of 0.5 to 2.0 mm obtained by slicing or rotary slicing. 5-50 pieces/7 individual 7 with a diameter of 0.5-2, Ornm
A hole 2 is drilled, and the hole-processed material veneer 1 and the unprocessed material veneer 7' as shown in FIG. Then, as shown in the same figure, a concave-convex deformed flitch 4 as shown in FIG. As shown in FIG. It is something to do.

In this way, the grain pattern is expressed on the material surface by repeating the layer 1a of the hole-processed material veneer 1 and the layer 1'a of the unprocessed material veneer 1'. layer 1 of
In a, the aforementioned hole 2 represents the conduit hole seen along the annual ring line in the natural ring-pore material, and it is possible to reproduce a material surface that closely resembles the natural ring-pore material.

Note that the stacking order of the hole-processed material veneer 1 and the unprocessed material veneer 1' may be, for example, as shown in FIG. 1,
Two unprocessed material veneers 1' are laminated in succession in the order of 1', 1', ...... The layer without conduit holes may be expressed thickly in the wood grain pattern of the ring-hole material reproduced in 1', 1. as shown in FIG. 'I...
Two material veneers 1 that have been subjected to hole processing in the order of... are laminated in succession to form an artificial decorative veneer 5'' as shown in Fig. 5.
The layer having conduit holes may be expressed thickly in the wood grain pattern of the ring-hole material reproduced on the # side.

Furthermore, the drilling angle for drilling holes in the material veneer may be approximately perpendicular to the surface of the material as shown in Figure 6, or it may be perpendicular to the surface of the material as shown in Figure 1. The hole may be drilled at an angle of about 70 degrees.

Furthermore, by subjecting the material veneer to a predetermined dyeing process before the lamination process, it is possible to obtain an artificial decorative veneer that is more similar to the natural ring-hole material that is to be reproduced, and the material veneer after the hole processing treatment If the board 1 and the unprocessed material veneer 1' are dyed separately, they can be made to resemble natural ring-hole material even more.

However, the dyeing process may be performed after slicing the unevenly deformed flitch 4.

Further, the hole-processed material veneer 1 and the unprocessed material veneer 1' may be wood of the same species or different species.

As described above, the method for manufacturing artificially decorated veneer of this invention is as follows:
A plurality of material veneers, including a material veneer with a plurality of holes with a diameter of 0.5 to 2.0 mm, are laminated together with an adhesive. Since the deformed flitch is obtained by pressing and gluing with a concave-convex mold, and this deformed flitch is sliced, it is possible to express the conduit characteristic of ring-hole material in the layer of the perforated veneer material, which is natural. It has the effect that it can be made into an artificial decorative veneer that closely resembles the ring-hole material.

Example 1 Thickness 0.8, 1, obtained by slicing Mangashinoro wood.
As shown in Fig. 6, on the surface of a material veneer of Qmm, diameters of 0.511. .0
A material veneer with a large number of holes drilled and treated with these holes and a material veneer without holes obtained by slicing white lauan wood were dyed under the following conditions.

Temperature: 90-95°C Bath ratio: 50 Time: 4.5 hours Dye: Hole-processed material veneer → Sinafast 41 mouth GL (manufactured by Mitsui Toatsu Chemical Co., Ltd.) 0.5% Unprocessed material veneer → Suminol Milling Brown 3G (manufactured by Sumima Kagaku Co., Ltd.) 1.5% The dyed perforated material veneer and the unprocessed material veneer are alternately laminated with an adhesive, compressed and bonded using an uneven mold. An unevenly deformed flitch was obtained, and this flitch was sliced in a certain direction to obtain an artificial decorative veneer.

On the surface of the resulting artificially decorated veneer, conduit holes were expressed along the circular mounds of tree-ring lines, and a wood grain pattern very similar to natural ring-hole wood was reproduced.

Example 2 A veneer of material to be hole-processed was obtained by slicing agathis wood with a thickness of 1.0 mm and 2.0 Il111! As shown in Fig. 1, 30 to 40
Holes with a diameter of 1.0 mm and 2.0 mm are drilled across the entire surface of the veneer at a ratio of 20/7 (12 holes with a diameter of 1.0 mm and 8 holes with a diameter of 2.0 mm). An artificial decorative veneer was obtained under the same conditions as in Example 1 above.

Conduit holes similar to those in the previous example were reproduced on the surface of the obtained artificially decorated veneer.
