Description

[Detailed Description of the Invention] The present invention relates to a method for manufacturing a decorative veneer,
The purpose is to provide a method for manufacturing decorative veneer that can express a wood grain pattern that closely resembles natural wood.

An embodiment of this invention will be explained based on FIG. 1 (Al or Il. That is, the method for manufacturing this decorative veneer
@Figure 1 (As shown in Al or Il, the nonwoven fabric 2 is laminated and pasted on a dyed or undyed material veneer 1 via an adhesive, and then the multiple sheets are made into an uneven or flat type)
A primary laminated flitch 3 is obtained by pressing and bonding using a resin adhesive, and this flitch 3 is sliced from the direction facing the laminated surface to obtain a secondary sliced veneer 4, which is then sliced. A composite veneer 6 is obtained by dyeing it according to the deafness and adhering it to a veneer 5 of another material that has been previously dyed.A plurality of composite veneers 6 are laminated in a concave-convex shape 7 with an adhesive and pressed. A secondary laminated fringe 8 is obtained by tightening and gluing, and a decorative veneer 9 is obtained by slicing the fringe 8 of C.

With this configuration, the 41st sliced veneer 4 and the dyed veneer 5 appear alternately on the decorative veneer, and the tree's annual ring layer 10 can be expressed by the 41st sliced veneer 4. In particular, when the nonwoven fabric 2 and the material veneer 1 are combined and the primary sliced veneer 4 o-) is dyed, one surface of the nonwoven fabric layer 11 is dyed with a dye and color unevenness is formed (the fourth
As shown in the figure (see El), it appears as uneven color in the annual ring layer IO, and can express the natural unpleasant taste as it is. In addition, the hardness is different between non-woven P52 and material veneer.
The surface of the primary sliced veneer 4 obtained by slicing the rice 1, -next ffl formation and edge 3 is uneven, and the natural unevenness of annual rings is expressed on the decorative veneer 9, which is the secondary sliced veneer. be able to. Especially the color unevenness of these tree ring layers 10? The uneven feel is ideal for A15 pine summer wood.

Next, an example of a body for obtaining a decorative veneer according to this embodiment will be explained.

Test Example 1: A non-woven fabric (brown) with a thickness of 0.2 tran was adhered on the Igem Rotor Q iQ root plate with a thickness of 1 rIm to obtain a multi-layer flitch, which was sliced at an angle of ]/100
1! direction) to obtain a 0.3-thick sliced veneer. This sliced veneer was pasted onto a 1.2-inch thick Igem Toshiki veneer to obtain a composite veneer, which was then layered in m layers, pressed and glued using a concave-convex mold, and further sliced. I got a decorative veneer. This item had a rich natural feel, resembling a pine tree with uneven coloring.

Test Example 2: Agathis rotary veneer with a thickness of 1.2 mm and a non-woven fabric with a thickness of 0.1 mm were alternately laminated in a concave and convex mold using an adhesive and then flitched to obtain a primary assembled flitch. This was sliced to obtain a secondary sliced veneer with a thickness of 0.5 to 0.02 mm.The sliced veneer was attached to an agathis dyed veneer, and multiple pieces were pressed and glued with a concave-convex mold. Then, after entering the chair, a decorative veneer with a Japanese cypress pattern having uneven summer wood parts was obtained. In other words, the method for manufacturing this decorative veneer involves bonding a plurality of dyed or undyed material veneers 1' with adhesive as shown in FIGS. The primary assembled frit 9chi 3' obtained by laminating, pressing and gluing the same number of uneven or flat shapes is sliced into two types of sliced veneers 12 and 13 with different thicknesses shown in the figure +D+ and tEl i. Then, these are pasted through the dyed veneer 5' upper plate adhesive J!1lJ14 to obtain an uneven composite veneer 6', and this composite veneer 6

i■ Two types of sliced veneers 12,134, each with a thickness of 0.2 to 1 tram and 0.1 to 0.25+a
m, and the thin veneer 13 has 16 holes and 1 partial hole.

By overlapping and pasting these sliced veneers 12 and 13 on the dyed veneer 5', the surface of the composite veneer 6' can be made uneven in thickness.

The decorative veneer 15 obtained using such a composite veneer 6' has an annual ring layer 16 that is uneven in width as shown in FIG.
This makes it possible to create C that expresses a wood grain pattern that closely resembles that of natural pine. Furthermore, by overlapping two types of sliced veneers 12 and 13 via the adhesive 14, color unevenness can be imparted to the annual ring layer 17, resulting in a more natural look.

Next, an example of how to obtain a decorative veneer according to this embodiment will be explained.

Test example 3: #Igem veneer dyed yellow (thickness 0, 8
The primary laminated fringe obtained by laminating, pressing, and gluing multiple sheets of "Sun" was sliced to a thickness of 0.8 am and a perforated thickness of 0.15+n+n, respectively. C Igem veneer dyed pale yellow (thickness 0.8 mm)
) to obtain a composite board. Several W pieces of this composite veneer were laminated in a concavo-convex mold using an adhesive, and then pressed and bonded to obtain a secondary assembled rim/edge. When I sliced this yellowtail border, I was able to obtain a decorative veneer with uneven width in the summer wood part.

Test Example 4: Dyeing in trace yellow (-Primary fruit obtained by pressing and gluing multiple pieces of Agatis platelets with a thickness of 0.8 rra with a hammer 111L = zchi with a thickness of 0.6■ and perforated slices with a thickness of 0.18 wn. These veneers were sliced with Agatis platelets stained pale yellow (1 mm thick).
), a decorative veneer was obtained in the same manner as in Example 3.

The width of the summerwood part of this one was uneven, forming a grain pattern similar to that of pine.

Still another embodiment of the present invention will be described with reference to @4□□□ to FIG. 6. In other words, this decorative veneer manufacturing method is able to express the wide summer wood part 18 found in natural coniferous trees such as pine and cypress, but the inside of the spring wood part is The nonwoven fabric is dyed using the same type of dye as that used for the dyed veneer to improve its light resistance.

Conventionally, in order to express the wide summer material part 18, a composite material obtained by making non-woven fabric 9 paper or the like blue with pigments to make the summer material part blue, and pasting it on a veneer of dyed material in the spring material part. Multiple plates were stacked together using adhesive, pressed and bonded together, and then sliced. On the other hand, when the decorative veneer obtained as shown in C was subjected to an accelerated fading test, the color tones of the spring wood part 19 and the summer wood part 18 were reversed, giving a strange feeling. This is because pigments have much better light resistance than dyes, and when comparing the resistance to natural wood, spring wood part 19 shows almost the same degree of discoloration as natural wood. The result was that the degree of discoloration of the summer wood portion 18 was much smaller than that of natural wood.

Therefore, in this embodiment, by dyeing the nonwoven fabric with a dye, the summer material part 18 is also discolored to the same extent as the spring material part 19.
This was achieved. Moreover, by using a dye, when the nonwoven fabric and the veneer for spring material are bonded together via an adhesive, the dye migrates and a transition layer can be provided near the interface between the nonwoven fabric and the veneer.

Next, a specific example for obtaining a decorative veneer according to this embodiment will be explained.

Test example A composite veneer made by pasting together with adhesive a veneer material for the spring material that has been dyed to a double-digit degree and a non-woven fabric dyed with a dye of approximately the same color as the dye used to dye the veneer. The sheets were pressed and adhered using an adhesive using a concave-convex mold. A decorative veneer obtained by slicing the obtained laminated frill 9chi into a thickness of 0.3 wun was adhered to plywood and painted to obtain a decorative material. This was subjected to a fading test (fade test), and both spring wood J9 and summer wood 18 were discolored to the same extent as natural wood, and the color of one spring wood was darker than that of summer wood 18. Never happened 1
child. At 1 year old, the boundary between summer wood section 18 and spring wood section 19 became less noticeable.

Note that a curved fibrous sheet such as paper may be used instead of the nonwoven fabric 1 used in these examples.

As described above, the method for producing a decorative veneer of the present invention involves laminating several sheets of raw material veneers via an adhesive (7 sheets of veneer and gluing them together to obtain a primary assembled flitch, and slicing these 7 sheets of veneer). The process consists of two steps: obtaining primary swiss small veneers by laminating the sliced veneers onto a raw veneer and gluing them together to obtain a composite veneer; and laminating multiple pieces of this combined veneer through a bonding agent. This process includes the steps of compressing and gluing, damaging the secondary laminated frillici, and slicing it (this has the effect of making it possible to express a wood grain pattern that closely resembles natural wood.

Next, a method for manufacturing decorative veneers will be explained. In other words, a fibrous sheet such as paper or non-woven fabric is used as a material to express the summer wood, and the spring wood is combined with a veneer of dyed material to create a spring wood and summer wood similar to those found in tree species such as In conventional decorative veneers, the surface color of the dyed veneer for the spring wood section overlaps with the color of the fibrous sheet for the summer wood section, making the color of the summer wood section darker. Therefore, there was a problem in that it was not possible to express the color of the summer wood, which is unique to shields and the like.

Therefore, as shown in Fig. 6 (Al Noshuku El), a fibrous sheet 20 colored M in the summer wood part and a dyed material veneer 21 in the spring wood part were pasted together with a titanium-containing adhesive to create a composite. Obtain the veneer 22, laminate the plurality of veneers in a corrugated two-row cutting die 23 using a titanium-proprietary adhesive similar to the above, press and adhere them, and slice the resulting 7 litho chips 24. Therefore, the surface color of the material veneer 21 can be hidden by the contact layer.Also, the adhesive used to bond the material veneer 21 and the fibrous sheet 20 and the adhesive used to bond the composite veneer 22 together can be used to hide the surface color of the material veneer 21. Since both the rM agent and the RM agent contain titanium, f Kotoe contains titanium only in the adhesive that bonds the composite veneers 22 together, and presses it with a multi-row mold 23 as shown in FIG. Part 2 corresponding to the X part of the mold 23 as in the case of tightening
In case 4, the color of the inner summer wood part 25 is hidden by the titanium-containing adhesive, so that the shade of the summer wood part 25 is not noticeable, but the part 26 corresponding to the Y part of the mold is opposite to the X part, so There is a problem that the shadow of the material part 25 is not hidden, giving a strange feeling (this is extremely effective for multi-row molding (for example, 5-row molding).

Incidentally, in addition to titanium, the above-mentioned MA adhesive can also use Ike's masking pigments, and furthermore, these hiding materials can be mixed with the adhesive together with a shielding agent.
