〔産業上の利用分野〕
この発明は床材、天井材、壁材等に使用する木材の着色
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method for coloring wood used for flooring, ceiling, walling, etc.
従来より、木材を着色し、その外観、意匠性を高めるこ
とは行われている０着色には、着色剤を木材内に一含浸
させる場合と、表面塗装にて着色する場合とがある。Conventionally, wood has been colored to improve its appearance and design.There are two types of coloring: one is to impregnate the wood with a coloring agent, and the other is to color the wood by surface coating.
一方、木材の寸法安定性等の諸物性を高めるために、樹
脂含浸処理（ｗｐｃ処理）も行われている。On the other hand, resin impregnation treatment (WPC treatment) is also performed to improve various physical properties such as dimensional stability of wood.
染料を用いて木材を着色する場合、染色後にブリーディ
ングが生じるおそれがあり、また染料は導管等には残ら
ないので、木目の強調には使用できないなどの欠点があ
り、使用Ｖ囲が限られていた。When coloring wood with dye, there is a risk of bleeding after dyeing, and since the dye does not remain in the conduit, it cannot be used to emphasize the wood grain. Ta.
また、前記樹脂含浸処理に際して、染料を混合して含浸
させることも考えられるが、含浸した七ツマ−をラジカ
ル重合させる際に、染料が重合の阻害等の問題をひき起
こすという問題があった。Furthermore, it is conceivable to mix and impregnate a dye during the resin impregnation treatment, but there is a problem in that the dye causes problems such as inhibition of polymerization when radical polymerizing the impregnated 7-summer.
このため、主として、顔料を使用する必要があった。For this reason, it was mainly necessary to use pigments.
しかしながら、顔料による着色では、木材の中に顔料が
入っていかず、全体の着色を行うことができなかった。However, when coloring with pigments, the pigments do not penetrate into the wood, making it impossible to color the entire wood.
したがって、この発明の目的は、木材を染料にて自由に
着色でき、併せて寸法安定化等の向上をも図った木材の
着色方法を提供することである。Therefore, an object of the present invention is to provide a method for coloring wood, which allows wood to be freely colored with a dye and which also improves dimensional stability and the like.
この発明の木材の着色方法は、木材に染料と水溶性樹脂
とを含浸または塗布し、樹脂を固化させるものである。The method for coloring wood according to the present invention involves impregnating or coating wood with a dye and a water-soluble resin, and solidifying the resin.
前記染料としては、水溶性のものであればいすへも使用
可能であり、たとえば酸性染料等があげられる。また、
水溶性樹脂としては、メラミン樹脂、フェノール樹脂、

は染色助剤としても利用できるものが多く、染色が簡単
に行える。As the dye, any water-soluble dye can be used for the chair, such as acid dyes. Also,
Examples of water-soluble resins include melamine resin, phenol resin,
Polyacrylamide, hydroxyethyl methacrylate (HEMA), polyethylene glycol methacrylate (PEGMA), etc. can be used, and many of these resins can also be used as dyeing aids, making dyeing easy.
第１図はこの発明の着色方法の原理を示す説明図である
。同図に示すように、木材ｌに染料２および水溶性樹脂

ると、染料が固化した樹脂４によって固定化される。し
たがって、染料２のブリーデイグを防止することができ
る。FIG. 1 is an explanatory diagram showing the principle of the coloring method of the present invention. As shown in the figure, when wood 1 is impregnated with dye 2 and water-soluble resin 3 and then resin 3 is solidified (or hardened), the dye is fixed by solidified resin 4. Therefore, bleeding of the dye 2 can be prevented.
また、第２図に示すように、木材ｌの表面を拡大すると
、表面の導管５等の凹部内に染料２が充填されるため、
木材１の組織だけでなく、導管５等の凹部内にも染料２
を同定することができる。Furthermore, as shown in FIG. 2, when the surface of the wood l is enlarged, the dye 2 is filled in the recesses such as the conduits 5 on the surface.
The dye 2 is applied not only to the structure of the wood 1 but also to the concave parts such as the conduit 5.
can be identified.
したがって、木目を強調する染色が可能となる。Therefore, dyeing that emphasizes the wood grain becomes possible.
また、塗布手段を用いた場合には、木目の着色を行うこ

が可能となる。Further, when a coating means is used, wood grain coloring can be performed. That is, as shown in FIG. 3, a water-soluble resin 7 mixed with a dye is applied to the surface of a wood 6, and after solidifying, the dye is fixed in the conduit 8 by sanding the surface with a sander. This enables wiping using dye.
木材単板（ナラ単板、厚さ０．５ｍｍ）を減圧釜に入れ

２時間乾燥、硬化させた。A wood veneer (oak veneer, thickness 0.5 mm) was placed in a vacuum pot and evacuated for 1 hour at a pressure of 10 mol.Hg or less. Then, a resin solution in which melamine resin (35%) and acid dye (5%) were dissolved in water was injected, and the pressure was maintained at reduced pressure for 10 minutes, and the pressure was returned to normal pressure. Thereafter, the wood veneer was taken out and dried and cured at 120° C. for 2 hours.
このようにして含浸処理した木材単板をビニルウレタン
系接着剤（１７０ｇ／ｎｆ）にて合板に貼り合わせた。The wood veneer thus impregnated was bonded to plywood using a vinyl urethane adhesive (170 g/nf).

床材とした。The bonding conditions were press at 120°C, 10 kg/cd, and 3 minutes. Then, it was painted with urethane paint and processed into flooring material.
得られた木質板は、未処理のものに比較して、耐汚染性
にすぐれており、１０％アンモニアにて２時間処理して
も水洗にて跡が残らなかった。The obtained wood board had superior stain resistance compared to untreated wood boards, and no marks remained after washing with water even after treatment with 10% ammonia for 2 hours.
また、硬度も、未処理物に比較して、パーコール硬度に
て１０〜２０程度上昇した。また、外観は、クリヤー塗
装にもかかわらず、木目が強調されていた。Moreover, the hardness also increased by about 10 to 20 in terms of Percoll hardness compared to the untreated product. Also, the wood grain was emphasized on the exterior despite the clear coating.
