Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves laminating a large number of veneers and reducing the % veneer tFE.
The flitch obtained by tightening and bonding is sliced along a cutting plane that passes through multiple veneers, and the wood grain (annual rings) is narrowed down using the connecting line of each sliced veneer. Surface filt polishing of veneer K than I
N! E[ilCO also relates to a method for producing an artificial decorative veneer with unevenness.

8 Generally speaking, softwood materials such as cedar have a summer wood portion and a spring wood portion.
The summer timber department is a ship permit. A sliced veneer made by slicing raw wood to reveal a wood grain pattern (shown in Figure 41'ellE1).

In the figure, (A) is the summer wood part, and Yu is the spring # part.

The surface of this sliced veneer (4)' is subjected to a so-called floating process and an uneven process to give it a three-dimensional effect. The artificially decorated veneer is produced in the following manner.
In other words, the raw wood is milled and cut to a fixed length (1) to make a line-colored veneer, and then a large number of dyed veneers are coated with a layering agent and laminated. do. At this time, a hard substance is added to the adhesive and laminated. Then, using a warm plate having a free curve IfI, a pressure-contact layer is applied to form a curved fringe, and then a sliced veneer (4 ).

Next, the surface of this sliced veneer (4) was polished to create a three-dimensional texture as shown in the second ea. The sliced veneer obtained in this way (41' is each material veneer + 1) is used as an artificial decorative veneer with a wood grain pattern on the border line ◇ Also, the expression of the wood grain, which is a good wood part like keratin, is noticeable. The packaging was made using adhesive or textile printing. And although the wood grain can be given an uneven feel by the above-mentioned polishing method, the sharp expression of the wood grain (-11 is far away, and the second
As shown in Figure (1) f-, the pigment has entered the conduits of the veneer 11) and the wood grain expression has become blurred and irregular rt7t.

Then there are nine problems.

The present invention provides the above-mentioned Q point #C ship, 7t4h, 10m of coniferous wood such as cedar, etc. - To provide a method for manufacturing an artificial decorative veneer with the purpose of improving the fidelity of natural wood with regard to the *a condition during uneven processing (so-called floating 9 processing) to express rough summer wood parts. Embodiment Q of the present invention will be described in detail below with reference to Figure tffi. First, the same as the conventional example @rr,,
Log woodworking Qλ5 chair cut to regular length veneer +
11 T-stain to make a stained veneer. And this veneer (
1)! ! The image is transferred using a transfer sheet, which is a transfer ink containing a pigment on the surface that contains an anti-wear agent. Here, as the anti-wear agent, aluminum oxide, carbon dioxide, etc. are used. Also available as a transfer sheet for poly I stell film.
Using a transfer sheet provided with Ii transfer ink, the transfer ink is transferred in this way, and a large number of sheets are laminated using T-adhesive (1). Then, as in the conventional example, the flitch is sliced to form a sliced veneer. Then, the surface of this sliced veneer (4) is polished to create irregularities. Here, the transfer ink layer formed by the transfer sheet expresses the annual rings, which are the sharp summer wood parts (a) shown in Figure 3 (False), and also contains wear-resistant # in the transfer ink even during polishing. rc, the summer wood part (A) was not polished, but only the spring wood SaO part was polished, as shown in Figure 3), which gives a sharp grain feel. The reason why a transfer ink layer is used in the transfer sheet is as follows. That is, even if an attempt is made to dye the surface Q of a wood veneer, the dyeing solution will inevitably penetrate into the interior and the annual ring area of the artificial wood grain will become blurred. However, in the case of transfer ink, there is almost no penetration into the interior S, so the tree ring world can be clearly expressed. Agatis wood 1.2 thick 0-tally veneer is dyed with acid dye to match the color of cedar spring wood (95±2℃)
After soaking for 4 hours), the * side of the dyed veneer was transferred to the * side of the dyed veneer using a transfer sheet made of a polyester film having an organic pigment layer containing 4 weights of aluminum oxide (average particle size: 107 All) in the color of cedar wood. After applying the transfer, this veneer is laminated,
Collect wLI on moisture-curing ML adhesive to form a flitch. Furthermore, this flitch f is sliced into 0.3 m thick pieces, obtained by slicing the flitch into 5 veneer veneers 0 afl. It has expression and an uneven three-dimensional feel.

I was able to obtain something that closely resembles natural cedar wood.

As described above, the present invention transfers a pigment containing an anti-wear agent over the entire surface of a wooden veneer using a transfer sheet.
A large number of these veneers are laminated with an adhesive and then pressed and fixed with adhesive to form a flitch tm, this flitch is sliced to form a sliced veneer, and the surface of the sliced veneer is polished. Therefore, by providing a transfer ink layer of Up pigment on the transfer sheet, the λ rate plate O! /? It is possible to express deep annual rings, and since the pigment transfer ink contains an anti-wear agent, even if the surface of the sliced veneer is polished, the part of the summer wood containing the anti-wear material will not be polished. First, only the spring wood part that does not contain wear resistance Wt is polished, and it is possible to express the three-dimensional effect of the wood grain by such uneven processing. Therefore, it is possible to improve the grain fidelity of softwood materials such as cedar It produces the effect that can be achieved.
