【発明の詳細な説明】
《産業上の利用分野》
本発明はWPC（ウツド・プラスチツク・コンビ
ネーシヨン）化した化粧板に関し、特にその杢目
を強調した化粧板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a decorative board made of WPC (Wood Plastic Combination), and particularly to a method for producing a decorative board with emphasized grain.
《従来の技術》
近年、減圧下で排気した木材の仮導管に樹脂を
注入して熱圧香硬化せしめる、所謂、木材と合成
樹脂の複合化（WPC）が普及してきた。<<Prior Art>> In recent years, so-called wood-synthetic resin composites (WPC), in which resin is injected into a tracheid of wood that has been evacuated under reduced pressure and cured under heat and pressure, have become popular.
一方、木材の材質感を高めると共に高級化のイ
メージを得る方法として、近年木材の杢目を強調
することが行われている。このような杢目強調方
法としては、木材中に存在する微量成分や色素
分が反応する杢目強調剤や杢目出し剤を塗布する
方法、ブラツシング等により単板表面に凹凸を
形成させ、凹部を凸部より濃色に着色させる杢目
逆転方法、及び熱硬化樹脂液中に予め染料を添
加せしめる方法が広く知られている。 On the other hand, in recent years, emphasis on the grain of wood has been used as a way to enhance the quality of wood and give it an image of luxury. Methods for emphasizing the heather grain include applying a heather grain enhancer or heather highlighter that reacts with trace components and pigments present in the wood, and forming unevenness on the surface of the veneer by brushing, etc. A method of reversing the grain pattern in which the convex portions are colored darker than the convex portions, and a method of adding a dye to the thermosetting resin liquid in advance are widely known.
《発明が解決しようとする課題》
しかしながらの方法を用いた場合には、夏材
部が春材部より濃色化され杢目が強調される結
果、全体に濃色化されるという欠点があり、の
方法の場合には、春材部が凹部、夏材部が凸部と
なるため、強調される杢目は本来の杢目と逆転し
た形となり不自然な杢目を形成するという欠点が
あつた。更にの場合には、杢目が今一つ不鮮明
である上、着色配合の異なる調整タンクを必要と
し、又は含浸釜の洗浄若しくは多数の釜が必要と
なるという欠点があつた。[Problem to be solved by the invention] However, when this method is used, there is a drawback that the summer wood part becomes darker in color than the spring wood part and the heather grain is emphasized, resulting in a darker color throughout. In the case of method , the spring wood part has a concave part and the summer wood part has a convex part, so the emphasized heather grain is reversed from the original heather grain, resulting in the formation of an unnatural heather grain. It was hot. Further, in such a case, there were disadvantages in that the grain of the grain was not clear enough, that adjustment tanks with different coloring formulations were required, or that the impregnating pots had to be washed or a large number of pots had to be used.
そこで、本発明者等は従来のかかる欠点を解決
すべく鋭意検討を重ねた結果、単板に熱硬化性樹

熱硬化性樹脂とを、それらの間で相互移動させる
ことにより、容易に杢目を強調し得ることを見出
し本発明に到達した。 Therefore, the inventors of the present invention have made extensive studies to solve these conventional drawbacks, and found that after impregnating a veneer with a thermosetting resin, the veneer is bonded to a base plywood by heat pressure curing. By adding an organic dye or the like in advance to the adhesive used to bond the veneer and the base plywood, and allowing the adhesive and thermosetting resin to mutually move between them, it is possible to easily create heathered grains. The present invention was achieved by discovering something that can be emphasized.
従つて、本発明の目的は、化粧板の杢目を強調

の製造方法によつて達成された。<<Means for Solving the Problems>> The above-mentioned object of the present invention is to impregnate a veneer with a thermosetting resin liquid, then attach the veneer to a base plywood that has been sealed, and apply the resin liquid. A method for producing a decorative board by heat-pressure curing the veneer and the base plywood, the resin component of the thermosetting resin being at least one selected from organic dyes, organic pigments, and inorganic pigments. This was achieved by a method for manufacturing a reinforced decorative board with emphasized grain, which is characterized by using an adhesive containing one type of adhesive.

物の中から適宜選択して使用することができる。 After curing, the thermosetting resin that can be used in the present invention may be transparent or opaque.
For example, styrene, methyl methacrylate, diallyl phthalate, saturated or unsaturated polyester,
The resin composition can be appropriately selected from among resins commonly used for impregnated wood such as melamine and phenolic resins, unsaturated polyesters containing shrinkage reducing agents, and other known thermosetting resin compositions.
これらの中でも、特に、メチルメタクリレー
ト、ジアリルフタレート及び不飽和ポリエステル
が好ましい。 Among these, methyl methacrylate, diallyl phthalate and unsaturated polyester are particularly preferred.

の空気を排出し、脱泡した樹脂液中に浸漬した後
加圧して該樹脂液を仮導管中に注入する方法が、
短時間に、大量に樹脂液を前記単板中に含浸せし
めることができるので好ましい。 In the present invention, the method for impregnating the veneer with the thermosetting resin liquid can be appropriately selected from known methods, but in particular, the air in the tracheids is discharged by reducing the pressure, and the resin is defoamed. A method of injecting the resin liquid into a tracheid by applying pressure after immersing it in a liquid is
This is preferable because a large amount of the resin liquid can be impregnated into the veneer in a short period of time.
WPC化に際する熱圧硬化の条件は、使用する
樹脂の種類に応じて公知の条件の中から適宜選択
して設定する。 Conditions for heat-pressure curing during WPC production are appropriately selected and set from known conditions depending on the type of resin used.

め単板に含浸せしめる熱硬化性樹脂液の樹脂成分
と一致することが好ましい。 The adhesive used to firmly bond the veneer and the base plywood during the heat-pressure curing described above permeates into the tracheids during heat-pressure, so it must be impregnated into the veneer in advance. It is preferable from the viewpoints of good compatibility with the thermosetting resin, ease of penetration, and difficulty in causing unevenness in the finish. In this sense, in the present invention, it is preferable that the original components of the adhesive, which do not contain organic dyes, organic or inorganic pigments, etc., match the resin components of the thermosetting resin liquid with which the veneer is impregnated in advance.

調色剤として染料を使用する事が好ましい。 The organic dye and organic or inorganic pigment used in the present invention can be appropriately selected from known dyes and pigments. Since dyes alone do not sufficiently emphasize the grain and are also inferior to pigments in light resistance, it is preferable to primarily use pigments with good light resistance, and to use dyes as subtle toning agents when necessary.

This is to prevent the adhesive from transferring to the base plywood and to allow the adhesive to efficiently move into the veneer, as will be described later. As this sealant, KR-137 (Koyo Sangyo Co., Ltd.), an aqueous vinyl urethane containing 10% by weight of TiO 2 , was used.
Use a publicly known product such as (manufactured by).

の移行が生じない上、単板として特に広葉樹を使
用した場合には、樹脂や染・顔料の移行が速やか
であるので、杢目の強調が効果的に行われる。<<Function>> As in the present invention, when a veneer impregnated with a thermosetting resin in advance is attached to a base plywood via an adhesive and heated to cure the thermosetting resin under heat and pressure, The viscosity of the resin solution decreases until the polymerization reaction progresses to a certain extent. Therefore, in the case of the claimed invention,
The resin and the adhesive composed of the resin and the dye/pigment move with each other at the interface between the impregnated veneer and the colored adhesive, thereby emphasizing the grain. In this case, since the base plywood is sealed in advance, the adhesive will not transfer to the base plywood, and if hardwood is used as the veneer, resins, dyes, and pigments will transfer quickly. Therefore, the heathered grain is effectively emphasized.
熱圧硬化時の接着剤の単板中への移行はわずか
であるから、このわずかな移行によつて杢目強調
の効果を出すためには、単板の厚みは２mm以下で
あることが良く、特に１mm以下であることが好ま
しい。 Since the migration of adhesive into the veneer during heat-pressure curing is slight, in order to achieve the effect of emphasizing the heathered grain through this slight migration, the thickness of the veneer should preferably be 2 mm or less. , especially preferably 1 mm or less.
《発明の効果》
本発明によれば、ブラツシング等の特別の操作
も杢目強調のための特別な装置も必要としないの
で、操作が単純であり製造コストも低減すること
ができる。<<Effects of the Invention>> According to the present invention, neither special operations such as brushing nor special devices for emphasizing the grain are required, so the operation is simple and the manufacturing cost can be reduced.
