DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel wood preservative treatment method.
- A novel method for preservative treatment of wood, characterized in that the wood is treated with a soda salt of an oxide, or that the treatment is followed by a secondary treatment with an aqueous solution of a metal salt.

近年木材は多量に使われ、その需要は年々増加の傾向に
ある。
In recent years, wood has been used in large quantities, and the demand for it is increasing year by year.

そして現在では需要の多様化にともなって国内における
供給のみではまかないきれず、諸外国から大量に輸入し
ているのが現状である。
Nowadays, as demand diversifies, it cannot be met by domestic supply alone, and large quantities are imported from other countries.

このような木材は貯蔵中あるいは製品化した後において
も、各種木材腐朽菌により腐朽されやすいことからこれ
らの病原菌の侵入により木材が腐朽化しないよう完全に
防腐処理を施しておく必要がある。
Even during storage or after being made into a product, such wood is susceptible to decay by various wood-destroying fungi, so it is necessary to completely preservative treatment to prevent the wood from decaying due to the invasion of these pathogens.

特に木材は十数年から何十年もの間使用されることが多
く、木材中で防腐剤の効力が長期間に亘り持続される必
要があり、極めて高い安定性と低い揮発性が要求される
In particular, wood is often used for many to several decades, so the effectiveness of preservatives must be maintained in the wood over a long period of time, and extremely high stability and low volatility are required. .

従来このような要求に基づき各種の無機化合物あるいは
有機化合物を防腐活性或分とする木材防腐剤が汎用され
ている。
Conventionally, based on such requirements, wood preservatives containing various inorganic or organic compounds as having some preservative activity have been widely used.

これらの木材防腐剤としては銅、クロム砒素系防腐剤(
以下CCA系防腐剤と略称する)、フェノール類フツ化
物系防腐剤(以下PF系防腐剤と略称する)、ペンタク
ロロフェノールのソーダ塩(以下PCPソーダと略称す

These wood preservatives include copper and chromium arsenic preservatives (
Examples include CCA-based preservatives (hereinafter abbreviated as CCA-based preservatives), phenolic fluoride-based preservatives (hereinafter abbreviated as PF-based preservatives), pentachlorophenol soda salt (hereinafter abbreviated as PCP soda), creonate oil, and the like.

これらが汎用されて来た理由としては、COA系防腐剤
、PF系防腐剤およびPCPソーダを或分とする防腐剤
がいずれにも水に溶解する性質を有することから、これ
らの防腐活性或分を木材に注入し防腐処理を施す場合に
、注入媒体として水が使用でき、有機溶媒を使用しッな
ければならない場合と異なり、安全で取り扱上も極めて
簡単なうえ、安価であることによるものである。
The reason why these have been widely used is that COA preservatives, PF preservatives, and PCP soda preservatives all have the property of being soluble in water. This is because water can be used as the injection medium when preservative treatment is applied to wood by injecting it into the wood, and unlike the case where organic solvents must be used, it is safe, extremely easy to handle, and inexpensive. It is.

しかしながら、これら公知の防腐剤は前記したような長
所と共に種々の短所も有している。
However, these known preservatives have various disadvantages as well as the above-mentioned advantages.

即ち、PF系防腐剤およびPCPソーダは水溶性である
ために前記のような長所を有する反面、木材中に注入し
た防腐活性威分が雨水等により流説しやすい欠点があり
、その結果、長期間に亘る接続的な防腐効果が期待でき
ない。
That is, although PF preservatives and PCP soda have the above-mentioned advantages because they are water-soluble, they have the disadvantage that the preservative activity injected into the wood is easily spread by rainwater, etc., and as a result, they do not last for a long time. A connective preservative effect over the period cannot be expected.

このような欠点を解消する方法として、PCPソーダを
公知の注入法で木材に加正注入した後、更に硫酸銅等の
金属塩で二次処理を施し、PCPソーダを木材中で水に
難溶性の塩に変えて固着し流説を防ぐ方法が知られてい
る。
As a method to eliminate these drawbacks, PCP soda is injected into the wood using a known injection method, and then subjected to a secondary treatment with a metal salt such as copper sulfate to make PCP soda in the wood poorly soluble in water. A known method is to replace it with salt to make it stick and prevent rumors.

しかしこのような改良法による場合でも、PCPソーダ
の木材への注入性状が良好でないために実際には実用化
されていない。
However, even with such an improved method, it has not been put to practical use because the injection properties of PCP soda into wood are not good.

また、CCA系防腐剤は水溶性ではあるが、前記した他
の水溶性防腐剤と異なり、木材に注入された後、CCA
系防腐剤が木材中の戊分と反応し、水に対して難溶性の
物質に変化するので、雨水等による流脱は極めて少ない
Also, although CCA preservatives are water-soluble, unlike the other water-soluble preservatives mentioned above, CCA preservatives are injected into wood.
The preservative reacts with the wood grains in the wood and turns into a substance that is poorly soluble in water, so there is very little chance of it being washed away by rainwater, etc.

しかしながら、砒素、クロム等の重金属を含む物質は保
健衛生上ならびに環境汚染防止上好ましくないために最
近ではCCA系防腐剤の使用は著るしく規制されつつあ
る。
However, since substances containing heavy metals such as arsenic and chromium are undesirable from the viewpoint of health and hygiene and prevention of environmental pollution, the use of CCA preservatives has recently been significantly regulated.

またクレオソート油は油状嘲質であるため、雨水等によ
る流説は少ないが、タール特有の汚染があり、しかもク
レオソート油を処理した木材は塗料による塗装ができな
いという致命的な欠点がある。
Furthermore, since creosote oil is an oily substance, there are few rumors that it is caused by rainwater, etc., but it is contaminated with tar, and wood treated with creosote oil has the fatal drawback that it cannot be painted with paint.

以上の理由から従来のこれら各種の防腐剤に代り、防腐
活性が高く、その活性が長期間に亘り持続的に発揮され
るうえに、保健衛生上ならびに環境汚染上問題がなく且
つ安全性の高い防腐剤の出現が強く望まれている。
For the above reasons, in place of these various conventional preservatives, we have developed a product that has high preservative activity, exhibits its activity sustainably over a long period of time, has no problems in terms of health and hygiene and environmental pollution, and is highly safe. The emergence of preservatives is strongly desired.

木材は極めて微細な多孔性の構造を持つので防腐剤を木
材に浸透させるには、木材内外の匡力差を利用して物理
的に含浸させる方法がもつとも一般的である。
Since wood has an extremely fine porous structure, in order to infiltrate the wood with preservatives, it is common to physically impregnate the wood by utilizing the difference in strength between the inside and outside of the wood.

そのため木材に対する薬剤吸収性あるいは木材或分と薬
剤との反応性の面で化学的にその防腐剤が浸透しやすい
性質を有しているか否かは木材処理上極めて重要なこと
である。
Therefore, it is extremely important in wood treatment whether or not the preservative has a chemical property that allows the preservative to penetrate easily in terms of drug absorption into the wood or reactivity of the wood with the drug.
