で安価な含浸法が求められていたのが実情である。[Prior art and technical problems to be solved] Conventionally, methods for impregnating the inside of wood with a treatment liquid (for example, dye, preservative, termiticide, or other modifying agent) include: i. treatment liquid; Immersion method, in which the wood is submerged in the wood to impregnate it; i. Boiling method, in which the wood is impregnated by boiling it together with a treatment liquid (open tank method); Processing method, in which the treatment liquid is injected into silkworms and wood under pressure to impregnate it. The pressure injection method (press-in method) is the most popular. However, the former two methods, immersion and boiling, both generate a large amount of waste liquid, which makes disposal difficult. Although the impregnation speed has become faster, there is a problem in terms of production efficiency because it takes a very long time to complete the impregnation process, and the latter boiling method requires a large amount of processing liquid and wood. Not only does boiling increase fuel consumption, but it also takes a considerable amount of time to process.
It is difficult to say that it is sufficient in terms of production cost and efficiency, and in addition, the pressure injection method (i) above has a better permeation rate of the treatment liquid than the immersion method or boiling method. Not only does this require equipment, but depending on the type of wood, the xylem tissue may be so dense that press-fitting may not be possible, so there was a need for a more efficient and less expensive impregnation method.
本発明は、従来における木材に対する処理液の含浸法が
前述のような情況であったことに鑑みて為されたもので

新方法を提供することを技術的課題とするものである。The present invention was made in view of the above-mentioned situation in the conventional method of impregnating wood with a treatment liquid. The technical objective is to provide a new method that allows efficient impregnation without any problems.
また、本発明の他の技術的課題は、木材の組織中に所望

理液含浸法を提供するにある。Another technical object of the present invention is to provide a method for impregnating wood with a treatment liquid, which allows a desired treatment liquid to be uniformly impregnated into the structure of the wood.
さらに、本発明の他の技術的課題は、木材組織を構成す

る。Furthermore, another technical object of the present invention is to provide an efficient method for making wood flame retardant by producing insoluble and nonflammable inorganic compounds in cells constituting wood tissue.
本発明者らが上記技術的課題を解決するために採用した
手段は、
（ａｌ 木材に水分を含ませて膨潤させ、この膨潤さ
れた木材を全体的に加熱して含水分を沸騰させることに
より当該木材を弾力的な柔軟状態に軟化させると共に、
木材組織を構成する細胞壁孔を開口させるという柔軟化
・透水性付与の加工手段と、
（ｂ） 弾力柔軟状態にある木材を加圧して圧縮させ
て処理液中で体積を復元させることにより当該木材組織
中に処理液を吸引含浸せしめるという強制吸液手段と、
を逐次的に施すというものである。The means adopted by the present inventors to solve the above technical problem is as follows: (al) By impregnating wood with water to swell it and heating the swollen wood as a whole to boil the water content. While softening the wood to an elastic and flexible state,
A processing method for softening and imparting water permeability by opening the cell wall pores that constitute the wood tissue, and (b) compressing the wood in an elastic and flexible state by applying pressure and restoring the volume in a treatment solution. A forced liquid suction means of suctioning and impregnating the treatment liquid into the tissue, and the following are sequentially applied.

含水分の沸騰によって木材が可逆的に柔軟弾性化する性
質を利用して対象とする木材を圧縮し、更に透水質化さ
れた当該圧縮木材を所要の処理液中で形状体積を復元さ
せることによって、木材組織中に処理液を吸弓含浸せし
めるという点に発想の要旨が存するのである。That is, in the present invention, when wood is sufficiently hydrated and the water content is heated and boiled, the xylem tissue temporarily changes into a soft and elastic material (while it is heated), and the cell wall of the main tissue changes. It focuses on the phenomenon in which the torus that were blocking the pores splits and the wood itself becomes permeable.
By compressing the target wood by utilizing the property that wood reversibly becomes flexible and elastic when water content boils, and then restoring the shape and volume of the compressed wood that has been made water permeable in the required treatment liquid. The gist of the idea lies in the fact that the treatment liquid is impregnated into the wood structure.

質、染色、脱色などの加工処理工程を大いに合理化する
こともできる。As explained above with reference to the examples, in the method of the present invention, the wood is sufficiently hydrated and the water content is heated and boiled to change the xylem tissue into a soft and elastic material, and the cell wall pores of the xylem tissue are The wood itself is made water permeable by destroying the torus that was blocking it, and the wood, which has become soft due to boiling water content, is compressed, and the compressed wood that has become water permeable is then compressed to the required size. This method restores the shape and volume in the treatment liquid and suctions the treatment liquid into the interior of the wood structure, allowing it to penetrate into extremely dense wood structures that could not be penetrated by conventional pressurized injection methods. In addition to being able to impregnate wood with processing liquids, the time required for impregnation treatment can be extremely shortened, greatly improving production efficiency, and the various processing liquids necessary for wood processing can be uniformly applied. It also becomes possible to impregnate wood with wood, greatly streamlining processing steps such as wood modification, dyeing, and bleaching.
このように本発明方法によれば、従来の浸漬法や煮沸法
における各種の問題（例えば、廃液処理、含浸速度の問
題）を簡単に克服できるうえに、加工処理に要するエネ
ルギーも大幅に節減することができるのであり、その産
業上の利用価値は頗る高いものと云える。As described above, according to the method of the present invention, various problems (e.g., problems with waste liquid treatment and impregnation speed) in conventional soaking and boiling methods can be easily overcome, and the energy required for processing is also significantly reduced. Therefore, it can be said that its industrial utility value is extremely high.
