Description
【発明の詳細な説明】 （産業上の利用分野〕 この発明は木材の含浸処理方法に関するものである。[Detailed description of the invention] (Industrial application field) This invention relates to a method for impregnating wood.
木材には腐る、燃える、狂う等の欠点があり、さらに床
材等に使用する場合は柔らかく、耐傷性に劣るという欠
点があった。Wood has disadvantages such as rotting, burning, and warping, and furthermore, when used for flooring, etc., it is soft and has poor scratch resistance.
これらの欠点を解消するために、従来より合成樹脂を木

がら、ＷＰＣ処理では、諸物性を向上させるために、樹
脂の含浸率を高くすると、硬度等の諸物性は向上する反
面、表面がいわゆる濡れ色になり、木質感が損なわれる
という問題があった。In order to eliminate these drawbacks, WPC treatment, which impregnates synthetic resin into wood, has been conventionally performed. However, in WPC treatment, when increasing the resin impregnation rate in order to improve various physical properties, while improving various physical properties such as hardness, there was a problem that the surface became so-called wet color and the wood texture was impaired. .
このような問題を克服するものとして、木材を無機処理
することがが堤案されている。すなわち、木材単板に無
機陽イオン（Ｍ＠、 Ｃｕ、＾ｌ、 Ｚｎ、 Ｂａ等の
カチオン）の水溶液を含浸し、ついで、無機陰イオン（
硫酸イオン、リン酸イオン、炭酸イオン等のアニオン）
の水溶液を含浸し、乾燥させて木材中に不溶性の無機化
合物を形成させるものである。In order to overcome these problems, it has been proposed to treat wood with inorganic materials. That is, a wood veneer is impregnated with an aqueous solution of inorganic cations (cations such as M@, Cu, ^l, Zn, Ba, etc.), and then inorganic anions (cations such as M@, Cu, ^l, Zn, Ba, etc.) are impregnated.
anions such as sulfate ions, phosphate ions, carbonate ions)
The wood is impregnated with an aqueous solution and dried to form an insoluble inorganic compound in the wood.
しかしながら、かかる無機処理においても、通常の樹脂
含浸などと同様に含浸物が木材の表面に集中しやすく、
とくに第５図に示すような無垢材３０の場合には含浸に
長時間を要していた。そこで、第６図に示すように、厚
さ５Ｔｌｌｌ以下程度の木材単板３１．３１を無機処理
し、基材３２（たとえば合板、パーティクルボード、集
成材、無垢材等）の片面または両面に貼着し、床材等に
使用することが考えられるが、無処理の基材３２を使用
すると、基材３２が腐食したり、燃えたり、狂ったりす
る欠点があり、できあがった製品自体もそのような欠点
をもつものとなる。However, even in such inorganic treatment, impregnated substances tend to concentrate on the surface of the wood, as in ordinary resin impregnation.
In particular, in the case of solid wood 30 as shown in FIG. 5, impregnation takes a long time. Therefore, as shown in Fig. 6, a wood veneer 31, 31 with a thickness of about 5 Tlll or less is inorganically treated and pasted on one or both sides of a base material 32 (for example, plywood, particle board, laminated wood, solid wood, etc.). However, if an untreated base material 32 is used, the base material 32 may corrode, burn, or become distorted, and the finished product itself may be subject to such problems. It will have some drawbacks.
上記欠点をなくすために、基材３２をあらかじめ樹脂含
浸処理したのち、無機処理した木材単板３１を貼着する
ことが考えられるが、これらの貼り合わせが困難であっ
た。In order to eliminate the above-mentioned drawbacks, it is conceivable to pre-impregnate the base material 32 with a resin and then attach an inorganically treated wood veneer 31, but it has been difficult to attach these.
また、木材単板３１内に生成した無機化合物は木材組織
と結合しているわけではないので、木材単板３１内の水
分の移動により無機化合物が表面に移動しするという問
題があった。とくに、無機イオンが木材単板３１の内部
にわずかにでも残留していると、長年の水分の吸収・放
出により、木材の表面に移行して、白い粉が析出する、
いわゆる白化現象が生じるおそれがあった。Furthermore, since the inorganic compounds generated within the wood veneer 31 are not bonded to the wood structure, there is a problem in that the inorganic compounds move to the surface due to movement of moisture within the wood veneer 31. In particular, if even a small amount of inorganic ions remain inside the wood veneer 31, they will migrate to the surface of the wood due to absorption and release of moisture over many years, and white powder will precipitate.
There was a risk that a so-called whitening phenomenon would occur.
この発明の木材の無機処理方法は、上記問題を解消する
べく完成されたものであって、木材中に無機陽イオンお

布するものである。The inorganic treatment method for wood of the present invention was completed to solve the above problems, and involves sequentially impregnating wood with an aqueous solution of inorganic cations and inorganic anions to form insoluble inorganic compounds in the wood. After that, it is impregnated or coated with resin.
前記木材には、木材単板のほか厚物の無垢材も含まれる
。木材単板の場合は、これを基材の片面または両面に貼
着したのち、樹脂含浸処理を施す。The wood includes thick solid wood as well as wood veneer. In the case of wood veneer, it is applied to one or both sides of the base material and then treated with resin impregnation.
前記無機陽イオンおよび陰イオンとしては、前述のよう
に別個に含浸されて木材単板中にて不溶性の無機化合物
を形成するものがあげられる。これらのイオンの含浸順
序はとくに制限されるものではない。The inorganic cations and anions include those which are impregnated separately to form insoluble inorganic compounds in the wood veneer, as described above. The order of impregnation with these ions is not particularly limited.
この発明における含浸処理方法としては、加圧含浸、減
