Description
本発明は、木材の種々の耐性を強化するところの木材の耐性強化処理方法と該方法により製造された耐性強化木材に関する。 [Technical Field] The present invention relates to a method for enhancing the resistance of wood, which enhances various resistances of wood, and to a resistance-enhanced wood produced by the method.
木材は、柱や塀、家屋の構成材料といった広い意味での建築材料として使用される他、工作性、加工容易性の理由により工芸用材料として使用されたりすることが多い。
こうした木材の使用に際しては、その耐性が高いほど経済価値も高くなるし、使用対象によっては、安全性なども問題となる。
このような一般的な木材の耐性強化を図った提案としては、次の従来技術を挙げることができる。
Wood is often used as a craft material for reasons of workability and ease of processing, in addition to being used as a building material in a broad sense such as pillars, fences, and building materials.
When using such timber, the higher its resistance, the higher the economic value, and depending on the object of use, safety becomes a problem.
The following prior art can be cited as a proposal for enhancing the resistance of such general wood.
上述した特許文献１の従来技術は、白蟻等の害虫駆除、防カビ、防腐の目的で、粉末状の炭と、消石灰又は漆喰と、ポリビニルアルコールと、水とを有する防蟻塗装剤を調整し、建築用ボードに塗布するものである。
しかし、このような防蟻塗装剤は、その原材料が複数必要で、プロセスも複雑であって、且つ、塗装故にボードの表面にのみ効果を発揮するものでしかない。尤も、白蟻のようにボードの表面を移動する場合には効果はあると考えられるが、塗装膜の内側に対する効果を期待できない。
The above-described prior art of Patent Document 1 adjusts an ant-proof coating agent having powdered charcoal, slaked lime or plaster, polyvinyl alcohol, and water for the purpose of controlling insects such as white ants, fungi and antiseptic. It is applied to building boards.
However, such an ant-preventive coating agent requires a plurality of raw materials, has a complicated process, and is only effective on the surface of the board because of painting. However, it is thought that there is an effect when moving the surface of the board like a white ant, but the effect on the inside of the coating film cannot be expected.
上述した特許文献２の従来技術は、木製板の難燃化を図るために、銅箔と、接着剤層及びシート状基材と、石灰含有組成物からなる化粧層とからなる積層構造を備える方法が提案されている。
しかし、かかる難燃化のための方法は、三つの素材の積層を形成しなければならず、複雑な構成となっており、且つ、銅箔層の下方の木材には何等の作用を持たせるものではなく、銅箔の剥離、亀裂によっては、内部の木材の影響を避けることはできない。
The above-described prior art of Patent Document 2 includes a laminated structure including a copper foil, an adhesive layer and a sheet-like base material, and a decorative layer made of a lime-containing composition in order to make the wooden board flame-retardant. A method has been proposed.
However, such a method for making flame retardant has to form a laminate of three materials, has a complicated structure, and has no effect on the wood below the copper foil layer. However, the influence of the wood inside cannot be avoided by peeling and cracking of the copper foil.
本発明は、かかる問題点に鑑み、極めて簡単な製造プロセスによって、低コストでもって、木材の耐性、即ち、防腐性、耐熱性（難燃化）を高め、カビ防止の効果を得るようにすることを目的とする。 In view of such problems, the present invention increases the resistance of wood, that is, antiseptic and heat resistance (flame retardant) and has an antifungal effect by a very simple manufacturing process at low cost.

It is characterized in that slaked lime penetrates and remains to the uncarbonized part of the wood.
本発明が対象とする木材は、一般の建築材、工芸材として用いられる、広葉樹或いは針葉樹であって、例えば、檜、杉、松、楓、楡等の全ての木材が対象となる。
本発明に言う完全炭化部分とは、炭化が完了している部分を言い、未炭化部分とは、炭化が完全になされていない部分及び木質部分を言う。
尚、上記炭化部分の削ぎ落としとは、炭化部分を全て削ぎ落すことを意味しない。
The wood targeted by the present invention is a broad-leaved tree or a coniferous tree used as a general building material or craft material. For example, all the wood such as firewood, cedar, pine, firewood and firewood is targeted.
The completely carbonized portion referred to in the present invention refers to a portion where carbonization has been completed, and the non-carbonized portion refers to a portion not completely carbonized and a woody portion.
It should be noted that scraping off the carbonized portion does not mean scraping off all the carbonized portion.

本発明にかかるその他の効果は、以下の実施例の記載から明らかとなろう。
According to the method for enhancing the resistance of wood and the resistance-enhanced wood of the present invention, the slaked lime and the carbonized part are obtained by performing a carbonization step for completely carbonizing the surface of the wood, a heating step, and a dipping step for immersion in a slaked lime solution. Can be obtained as if they were covered with a slaked lime film, providing anti-fungal and anti-mold wood at a low cost. It is a thing. Thereby, the tolerance as a craft material increases as a part of building materials.
Other effects according to the present invention will be apparent from the description of the following examples.
本発明の実施に際しては、前記消石灰溶液は、容積計量の消石灰粉１８０ｃｃ〜２００ｃｃを水８００ｃｃ〜９００ｃｃの割合で溶解させたものであることが好ましい。
このような比率の消石灰溶液は、表面が炭化した木材に対して内部まで浸透させるに十分の希釈性があり、炭化部分のみならず、未炭化部分、即ち、下層の茶色く変色した部分、更には、内部の木質部分に対して比較的短時間でも浸透させることが出来る。
また、希釈度が高いことで、乾燥に際して水分の蒸発を促進でき、乾燥を良好に行うことができる。
In practicing the present invention, the slaked lime solution is preferably obtained by dissolving 180 cc to 200 cc of volumetric slaked lime powder in a ratio of 800 cc to 900 cc of water.
This ratio of slaked lime solution is sufficiently dilutable to penetrate into the interior of the wood whose surface is carbonized, and not only the carbonized part, but also the uncarbonized part, that is, the lower brown colored part, It can be penetrated into the wood part of the inside even in a relatively short time.
Further, since the degree of dilution is high, evaporation of moisture can be promoted during drying, and drying can be performed satisfactorily.
更に、前記木材の炭化部分の削ぎ落としは、未炭化部分の下層の茶色に変色した部分、即ち、未炭化部分まで進行させることができる。
木材としての用途にもよるが、このように強度を持たない炭化部分を削ぎ落としたとしても、消石灰分の浸透残留によって、下層においても防腐性、耐熱性（難燃化）、カビ防止の効果を発揮できる。
また、このような削ぎ落とし後の表面は、研磨を行うと、消石灰の浸透によるものと推測されるが、表面に艶が生まれ、見た目にも綺麗である。
Further, scraping off the carbonized portion of the wood can proceed to the brown-colored portion below the uncarbonized portion, that is, the uncarbonized portion.
Although it depends on the use as wood, even if the carbonized parts that do not have such strength are scraped off, the slaked lime content will remain, resulting in antiseptic, heat-resistant (flame retardant) and mold prevention effects in the lower layer. Can be demonstrated.
Further, when the surface after such scraping is polished, it is presumed to be due to the penetration of slaked lime, but the surface is glossy and is visually beautiful.
本発明にかかる木材の耐性強化処理方法について、以下詳述する。
第１の工程として、木材、ここでは、杉木材を用い、その表面を、炭化部分が形成されるまで炭化させる。
これには、電気炉を用い、窒素ガスを注入して、約１０００℃で行う。広葉樹の木材であれば、４００℃乃至７００℃が適切である。尚、窒素ガスを注入しないで、酸素侵入を遮断する炉の構造とし、燃焼を阻止して炭化させる方法を採ってもよい。
上述の方法として、大型の木材であれば、其れに見合った加熱炉を用いるようにする。
The method for enhancing the resistance of wood according to the present invention will be described in detail below.
As a first step, wood, here, cedar wood is used, and its surface is carbonized until a carbonized portion is formed.
This is performed at about 1000 ° C. using an electric furnace and injecting nitrogen gas. For hardwood wood, 400 ° C to 700 ° C is appropriate. Note that a furnace structure that blocks oxygen intrusion without injecting nitrogen gas may be used to prevent combustion and carbonize.
As the above-mentioned method, if it is a large timber, the heating furnace corresponding to it is used.
木材の表面炭化は、その木材の使用目的によって、その深度を調節する。強度を要求される建材としては、後に炭化部分を削ることになるので、その強度を発揮できる余裕を持たせた寸法の木材の表面を炭化させることになる。また、工芸材或いは装飾材として用いる場合等、その炭化部分の全てを削ぎ落とすこともあるが、これに見合った寸法の木材を準備することになる。 The surface carbonization of wood adjusts its depth according to the intended use of the wood. As a building material that requires strength, the carbonized portion will be cut later, so that the surface of the timber having a margin that can exhibit its strength is carbonized. Moreover, when using as a craft material or a decoration material, all the carbonization parts may be scraped off, but the wood of the dimension corresponding to this is prepared.
次いで、当該木材を加熱する。この加熱は、１５０℃から２００℃程度で行う。この加熱は、次工程の消石灰溶液への浸漬に際して、浸透性を高めるために行う。
この後、直ちに、当該木材を消石灰溶液に浸漬する。この消石灰溶液は、消石灰（Ｃａ（ＯＨ）２）を、ここでは、２００ｃｃ（カップ計量）を準備し、これを８００ｃｃの水に溶解する。この水は、一旦沸騰させて塩素を抜いておき、生暖かい温度の（略１５℃乃至３０℃程度）のものが準備される。
Next, the wood is heated. This heating is performed at about 150 ° C. to 200 ° C. This heating is performed in order to increase the permeability when immersed in the slaked lime solution in the next step.
Immediately thereafter, the wood is immersed in a slaked lime solution. This slaked lime solution prepares slaked lime (Ca (OH) 2), here 200 cc (cup weighing), and dissolves it in 800 cc of water. This water is boiled once to remove chlorine, and is prepared with a warm temperature (approximately 15 ° C. to 30 ° C.).
前記消石灰粉の濃度は、１８０ｃｃ〜２００ｃｃに対して、水８００ｃｃ〜９００ｃｃで溶解するのが、木材への浸透性を配慮すると好適である。この状態は、粘りがなく、散り散りでもなく、粒子が均一に水中に在り、揺らすと粒子が埃のように舞い上がる状態のものである。
そして、消石灰溶液への浸漬は、ここでは、２０時間とした。尤も、１５時間乃至３０時間の範囲であれば、炭化部分、内部の未炭化部分、木質部分への十分な浸透状態が得られることが実験によって検証されている。尚、消石灰溶液は、必要に応じて攪拌する。
The concentration of the slaked lime powder is preferably from 800 cc to 900 cc with respect to 180 cc to 200 cc, considering the permeability to wood. In this state, there is no stickiness, no scattering, the particles are uniformly in the water, and the particles rise like dust when shaken.
The immersion in the slaked lime solution was 20 hours here. However, it has been experimentally verified that a sufficient penetration state into the carbonized portion, the inner uncarbonized portion, and the woody portion can be obtained in the range of 15 hours to 30 hours. In addition, a slaked lime solution is stirred as needed.
次いで、当該木材を乾燥させる。この乾燥は、ここでは、初期においては、温風を当てることで所定の乾燥を行い、しかる後に自然乾燥させることとした。尤も、場合によっては、温風、乾燥空気による強制乾燥を継続させることで、時間短縮を図るようにしてもよいが、自然乾燥の方が木材にとって好ましいことは判明している。乾燥程度としては、残留水分が２０％以下になるようにする。 Next, the wood is dried. Here, in the initial stage, the drying is performed by applying a warm air to perform a predetermined drying, and then naturally drying. However, in some cases, forced drying with hot air or dry air may be continued to shorten the time, but it has been found that natural drying is preferable for wood. The degree of drying is such that the residual moisture is 20% or less.
乾燥後の木材は、その炭化部分の一部が削ぎ落とされる。これには、研磨作用が同時に得られるバフ研磨盤を用いる。しかし、木材の使用目的（工芸品等）によっては、ヤスリ、ノミによって手作業で落とすこともある。
当然ながら、寸法については、削り代を考慮した当初の木材が準備されているので、必要寸法まで加工することになる。
A part of the carbonized portion of the wood after drying is scraped off. For this, a buffing machine capable of obtaining a polishing action at the same time is used. However, depending on the purpose of use of the wood (crafts, etc.), it may be manually removed with a file or chisel.
As a matter of course, since the original timber considering the machining allowance is prepared, the required size is processed.
この炭化部分の削ぎ落しは、下層の茶色に変色した部分まで進行させることもある。
例えば、木目を生かすべく、この木材を床の間の要部や、欄間等に用いる場合、建築材として、目に付き易い場所に用いる場合には、炭化部分が残ると見た目も悪く、炭化部分が消石灰で固定化させているとしても、接触されることが好ましくない。
The carbonized portion may be scraped off to the lower brown portion.
For example, when this wood is used in a main part between floors or in a space to make use of the grain, when it is used as a building material in a place where it is easily noticeable, if the carbonized part remains, it looks bad, and the carbonized part is slaked lime. Even if it is fixed by, it is not preferable to be contacted.
このようにして処理した木材は、少なくとも木材の炭化部分とその炭化部分直下層の木材部分とに亘って石灰が浸透残留されてなるため、防腐性、耐熱性（難燃化）、カビ防止の効果を発揮できるところから、所要の寸法加工等を施して、家屋の各所の建材として、或いは、工芸用材として非常に有用であり、また、表面の削ぎ落としによって、逆に、表面に艶が生まれるということもあって、種々の利用目的に使用できる。 The timber treated in this way has lime permeated and retained at least over the carbonized portion of the wood and the wood portion immediately below the carbonized portion, so that it has antiseptic properties, heat resistance (flame resistance), and mold prevention.
