【発明の詳細な説明】 この発明は集成化粧単板等の集成材の製法に関するもの
である。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing laminated wood such as laminated decorative veneer.

一般に、けやき等の波状環孔材の孔開にみられるような
立体集中道管が形成されている集成化粧単板は、これま
でつぎのようにして製造されていた。
In general, laminated decorative veneers in which three-dimensional convergence channels are formed, such as those seen in the perforations of corrugated annular porous materials such as zelkova, have been manufactured in the following manner.

第1の方法は、道管数の多い南洋材(例えば、エリマ、
ラワン)の単板に脱色、染色処理を施し、これを孔開表
現用単板として用い、非孔圏表現用単板と積層接着して
フリッチ化しスライスするという方法である。
The first method is to use South Sea wood with a large number of tubes (e.g. frill,
This method involves decolorizing and dyeing a veneer of lauan, which is used as a veneer for expressing perforations, and then laminating and bonding it with a veneer for expressing non-porous areas, forming flitches, and slicing.

チ化し、これを積層面に平行にスライスすることにより
集成化粧単板を製造するという方法である。
The second method is to tone the raw wood veneer to an appropriate color tone, then
A plurality of veneers are laminated with an adhesive, pressed together with a pair of flat dies to form a primary flitch, and the resulting primary flitch is sliced (straight-grained) to produce a primary sliced veneer. Next, this is made into a veneer for expressing perforations, laminated with a commonly used veneer (veneer for expressing non-porous areas) via adhesive, and pressed with a pair of uneven molds that have unevenness on the mold surface. This is a method in which a laminated decorative veneer is manufactured by tightening the flitch to form a secondary flitch and slicing it parallel to the laminated surface.

第8の方法は、第2の方法において、1次フリッチ製造
時に、接着剤の上に木粉を散布して積層するという方法
である。
The eighth method is a method in which, in the second method, wood flour is sprinkled on the adhesive and laminated at the time of primary flitch production.

しかしながら、これらの方法にはそれぞれっぎのような
問題があった。すなわち、第1の方法によって得られる
集成化粧単板は、道管の絶対数が不足しており自然感に
欠ける。第2の方法は、1次スライス単板の接着剤層(

、道管が平面的であり天然品のような立体感に欠ける。
However, each of these methods had its own problems. That is, the laminated decorative veneer obtained by the first method lacks the absolute number of vessels and lacks a natural feel. The second method uses the adhesive layer (
, which appear like wood grain) to express the vessels, the vessels are flat and lack the three-dimensional feel of natural products.

そのうえ、得られる集成化粧単板の表面にワイピング塗

浸されにくいという問題がある。
Furthermore, even if the surface of the resulting laminated decorative veneer is applied with a wiping coating, the paint does not impregnate the vessels like a natural product. The eighth method is to create voids for expressing a three-dimensional effect in the adhesive layer of the first sliced veneer by scattering wood flour on the adhesive during the production of the first flitch. During manufacturing, the adhesive used enters the voids in the adhesive layer of the primary sliced veneer, so there is a problem that paint is difficult to impregnate even if the resulting laminated decorative veneer is subjected to wiping painting.

This invention was made in view of the above circumstances, and consists of forming a primary flitch by laminating and adhering a plurality of thin sheet-like bodies through an adhesive and wood powder, and slicing this primary flitch. Make the first slice veneer and use this 1
This is a method of manufacturing laminated wood in which a secondary flitch is created using the next sliced veneer as a veneer for expressing holes, and a laminated wood is obtained by processing this secondary flitch, and the process is performed prior to forming the secondary flitch. The gist of this method is to form a film using a film-forming agent that lacks permeability on the veneer surface of the primary sliced veneer.

That is, by forming a film using a film-forming agent that lacks permeability on the surface of the primary sliced veneer as described above, adhesion to the voids in the adhesive layer of the primary sliced veneer is improved during secondary flitching. Penetration of the agent is blocked, and the voids (the film-forming agent lacks permeability, so it does not penetrate into the voids during film formation) appear on the surface of the laminated wood such as laminated decorative veneer. Therefore, the vessel becomes three-dimensional, and during wiping painting, the paint is impregnated in the same way as a natural product.

As the adhesive for bonding the thin sheet, a urethane adhesive is usually used. In addition, the wood powder used with the adhesive is not particularly limited, but considering the diameter of the concentrated pipe of natural products, the size of the voids that improve the impregnation of the paint during wiping painting, etc., the particle size It is preferable to use one with 14 to 82 meshes, and the amount used is 8

As a film-forming agent (sealing agent) that lacks permeability and is applied to the veneer surface of the primary slice veneer for expressing holes, for example, water-soluble materials such as carboxymethylcellulose (CMC) and methylcellulose, which have excellent film-forming ability, can be used. These resins are used in the form of an aqueous solution with a viscosity of several hundred to several thousand cps.

The production of laminated wood such as laminated decorative veneer is made by first slicing the veneer to express holes, which has undergone the above-mentioned treatment, and then removing it to an appropriate color tone.
A non-perforated expression veneer that has been dyed, etc. is laminated with an adhesive, pressed with a concave-convex mold to form a secondary flitch, and then, for example, this can be sliced (to obtain a laminated decorative veneer) or planed. This is done by carving, sawing, and finishing (glued laminated wood in the shape of a plate or column is obtained which is thicker than a laminated decorative veneer).
