【発明の詳細な説明】 （技術分野） 本発明は木材の改質技術の一つである合成樹脂含浸着色
木材に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to synthetic resin-impregnated colored wood, which is one of wood modification techniques.

（背景技術） 木材を着色する方法としては、従来より化学着色処理、
染色処理等がある。又、合成樹脂含浸木材を着色する方
法としては、木材に注入含浸する合成樹脂に染料、顔料

成樹脂含浸着色木材を得る方法がある。(Background technology) Conventional methods for coloring wood include chemical coloring treatment,
There are dyeing treatments, etc. Further, as a method for coloring synthetic resin-impregnated wood, there is a method in which a coloring agent such as a dye or pigment is added in advance to a synthetic resin to be injected into the wood, and then the wood is injected and impregnated to obtain synthetic resin-impregnated colored wood.

しかしながら上記した従来の方法には、次の様な欠点が
あった。However, the conventional method described above has the following drawbacks.

■　化学着色処理、染色処理のみを行なっても木材全体
が同一色調となり木目強調の目的である道管部のみが濃
色にしにくい。■ Even if only chemical coloring or dyeing is applied, the entire wood will have the same color tone, making it difficult to darken only the vessel area, which is the purpose of highlighting the wood grain.

■　着色合成樹脂を用いると道管部は濃色となるが、合
成樹脂に着色できる種類に制限が生じる。■ When colored synthetic resin is used, the vessel becomes dark colored, but there are restrictions on the types of synthetic resin that can be colored.

（合成樹脂を貯蔵しておくタンクの数で着色できる種類

釜内部、配−Ｗ等の樹脂を十分除去しておかないと曲の
色が混じる恐れもある。(The number of tanks in which the synthetic resin is stored determines the types that can be colored.) Also, when changing the colored synthetic resin, it is necessary to remove enough resin from inside the vacuum cooker, wiring W, etc. There is also a risk of color mixing.

即ち、かかる方法は、大希少品種向きではあっても少量
多品種の生産には支障をきたす結果となっていた。That is, although this method is suitable for very rare varieties, it poses a problem in producing a wide variety of products in small quantities.

（発明の目的） 木材全体を染色処理にて、日型とする色調に着色する。(Purpose of the invention) The entire wood is dyed to give it the shade of a sun pattern.

あるいは染色液を木材に塗布することで行なう。In addition, in the 11th edition that is dyed, degreasing treatment is applied as a pretreatment.
Is the wood bleached and dyed with a dye solution? pickles,
Alternatively, this can be done by applying a dye solution to the wood.

次いで、この着色木材に従来方法である減圧・加圧法に

樹脂をセミ硬化させる。Next, a synthetic resin is injected and impregnated into the colored wood using the conventional method of vacuum/pressure, and the synthetic resin is semi-hardened using hot air.

である。Alternatively, a colored synthetic resin is applied to a semi-cured veneer and hot-pressed to embed the coloring agent in the vessel and harden it. In this way, it is an object to easily obtain colored wood impregnated with a synthetic resin in which the vessel part of hardwood is darkened and the grain of the wood is emphasized.

合成樹脂を単板に含浸させる。Obtain veneer from logs using rotary lace, slicer, etc. The thickness of the veneer varies depending on the final product, but in the case of flooring, it is preferably about 0.3 to 31 El. If the inside of this veneer is to be colored, it is colored by performing conventional degreasing, bleaching, and dyeing processes. (If only the surface is to be colored, it is possible to do so by dyeing only.) Next, this colored veneer is dried by hot air, high frequency, etc. to a moisture content of 10% or less, placed in a vacuum-pressure cooker, and subjected to the vacuum-pressure method. The veneer is impregnated with synthetic resins such as unsaturated polyester ρ and methyl methacrylate.

含浸終了後、単板表面に付着している余分な樹脂を除去
し、熱風によシ、セミ硬化させる。After the impregnation is complete, remove excess resin from the surface of the veneer, blow it away with hot air, and allow it to semi-cure.

着色剤を塗布する工程は、次の３つに別けられる。The process of applying the colorant can be divided into the following three steps.

■　セミ硬化単板を、接着剤を塗布した合板上に置き、
