【発明の詳細な説明】
〔技術分野〕
この発明は木質単板等の木材の含浸処理方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for impregnating wood such as wood veneer.
〔背景技術]
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。[Background Art] Wood has drawbacks such as rotting, burning, and warping, and furthermore, when used as flooring materials, 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
材内に含浸させるWPC処理が行われている。しかしな
がら、WP’C処理では、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欠点があった。In order to eliminate these drawbacks, WPC treatment, which impregnates synthetic resin into wood, has been conventionally performed. However, in WP'C treatment, when the resin impregnation rate is increased,
Although various physical properties such as hardness were improved, the surface had a so-called wet color and the woody feel was impaired.
そこで、2種の無機塩の水溶液を木材内に含浸させ、木
材中にてこれらを反応させて不溶性の無機化合物を生成
させ木材を改質することが提案されている。かかる無機
処理では、たとえ多量の無機塩を含浸させても、木材が
濡れ色になることがないという利点がある。Therefore, it has been proposed to impregnate wood with an aqueous solution of two types of inorganic salts and react in the wood to generate an insoluble inorganic compound to modify the wood. Such inorganic treatment has the advantage that the wood does not become wet colored even if it is impregnated with a large amount of inorganic salt.
しかしながら、無機処理によって、目的とする物性(防
腐2.難燃性能、硬度等)を得るためには、多量の無機
塩を含浸させる必要があるが、多量の無機塩を均一に含
浸させることは困難であり、また多量に含浸させると無
機塩の消費量が多くなるために製造コストが高くなると
いう問題があった。However, in order to obtain the desired physical properties (preservation, flame retardancy, hardness, etc.) through inorganic treatment, it is necessary to impregnate a large amount of inorganic salt, but it is difficult to uniformly impregnate a large amount of inorganic salt. Moreover, impregnating a large amount of the inorganic salt increases the consumption of the inorganic salt, resulting in an increase in production cost.
この発明の目的は諸物性にすぐれた表面を有する改質木
材を簡単にかつ安価に得ることができる木材の含浸処理
方法を提供することである。An object of the present invention is to provide a method for impregnating wood that can easily and inexpensively obtain modified wood having a surface with excellent physical properties.
この発明の木材の含浸処理方法は、互いに反応して不溶
性化合物を形成する2種の木材改質剤のうち少なくとも
一方の改質剤を加圧して木材中に含浸させるものである
。The wood impregnation treatment method of the present invention involves impregnating into wood by pressurizing at least one of two types of wood modifiers that react with each other to form an insoluble compound.
このように、木材改質剤を加圧して含浸させるため、と
くに木材の表面側に多量に改質剤が含浸され、木材の表
面硬度、防腐性、難燃性等の特性が向上する。また、加
圧含浸するため、短時間で処理することが可能になる。In this way, since the wood modifier is impregnated under pressure, a large amount of the modifier is impregnated, especially on the surface side of the wood, and properties such as surface hardness, antiseptic properties, and flame retardance of the wood are improved. Furthermore, since the impregnation is carried out under pressure, the treatment can be carried out in a short time.
前記2種の木材改質剤はそれぞれ無機液であり、このう

の改質剤の含浸順序はとくに制限されるものではない。The two types of wood modifiers are each an inorganic liquid, and one of them contains Mg, Ca, AI, Zn,
One generates cation ions such as Ba, and the other generates anion ions such as sulfate ions, phosphate ions, carbonate ions, etc. in an aqueous solution. These modifiers are impregnated into wood in the form of an aqueous solution, and upon drying produce inorganic compounds that are insoluble in the wood. The order of impregnation of the two types of modifiers is not particularly limited.

に好ましい。The modes of impregnation treatment in this invention include: (1) impregnating both modifiers under pressure; (2) impregnating only the first modifier with pressure, and impregnating the second modifier with reduced pressure or regular impregnation. There are three methods: pressure immersion; (2) the first modifier is impregnated under reduced pressure or normal pressure; and the second modifier is impregnated under pressure. Of these, the above ■
Pressure impregnation with only the second modifier as shown above is particularly preferred in order to further improve the uniformity of impregnation and the physical properties of the wood surface.

0mmHg以下に減圧したのち、改質剤を注入し、つい
で常圧に戻して浸漬処理し、さらに必要に応じて加圧す
る。また、常圧浸漬は改質剤の溶液中に木材を浸漬する
ものである。In the vacuum impregnation process, the wood is first placed in a vacuum pot, and the inside of the pot is
After reducing the pressure to 0 mmHg or less, a modifier is injected, and then the pressure is returned to normal pressure for immersion treatment, and further pressurization is applied as necessary. Also, normal pressure immersion involves immersing wood in a solution of a modifier.
両改質剤の含浸処理後、処理木材を乾燥させることによ
り、これらの改質剤が木材中で反応して不溶性の無機化
合物を形成する。After the impregnation treatment with both modifiers, the treated wood is dried so that these modifiers react in the wood to form insoluble inorganic compounds.
次に実施例をあげてこの発明の木材の含浸処理方法を説
明する。Next, the method for impregnating wood according to the present invention will be explained with reference to Examples.
実施例1: 米松単板(厚さ15+wm)を減圧下(1

The wood was immersed in a second modifier solution in which 7 kg was dissolved, and the wood was immersed at a rate of 15 to 20 kg/cJ'? ! Impregnation was carried out under pressure for over 1 hour.
加圧含浸後、木材を24時間水洗し、40°Cにて乾燥
させ、表面を塗装処理して改質木材を得た。After pressure impregnation, the wood was washed with water for 24 hours, dried at 40°C, and the surface was painted to obtain modified wood.
実施例2: 米松単板(厚さ1OIII11)を飽水処

た。Example 2: A second modification was carried out in the same manner as in Example 1, except that a Japanese pine veneer (thickness 1OIII11) was saturated with water and then immersed in the first modifier solution at 60°C for 24 hours. The material was impregnated with the wood quality agent solution under pressure, washed with water, and dried to obtain modified wood.
実施例3: 第1の改質剤と第2の改質剤の含浸順序を
