この発明は、建材等として用いられる改質木材の製法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for producing modified wood used as building materials and the like.
不溶性不燃性無機物を木材中に含ませて、難燃性、防腐
・防虫性および寸法安定性を付与した改質木材を得る改
質木材の製法が開発されている。A method for producing modified wood has been developed in which wood is impregnated with insoluble and noncombustible inorganic substances to obtain modified wood that has flame retardancy, antiseptic/insect repellent properties, and dimensional stability.
木材の難燃化について、つぎに説明する。Next, flame retardant wood will be explained.
木材に難燃性を付与するための処理法として、種々の方
法がある。難燃化のメカニズムから分類すると、大体、
つぎのように分けられる。There are various treatment methods for imparting flame retardancy to wood. When classified based on the mechanism of flame retardancy,
It can be divided as follows.

In addition to (b), depending on the type of inorganic substance, effects due to other mechanisms can also be expected. Furthermore, insoluble, nonflammable inorganic substances are less likely to be dissolved out of the wood, so there is less risk of their effectiveness being diminished.
(alおよび(b)のメカニズムについて、つぎに詳し
く説明する。(alの無機物による被覆は、たとえ、可
燃性の材料であっても、不燃性の無機物と適当な配合比
で複合すれば、難燃化しうるということである。たとえ

不燃性のセメントと約1対1の重量配合比で混合し、板

炭化が促進される。こうして形成された炭化層が断熱層
として作用し、難燃効果が生じる。The mechanisms of (al and (b)) will be explained in detail below. (Al, even if it is a flammable material, it will be difficult to coat it with an inorganic material if it is combined with a non-flammable inorganic material at an appropriate blending ratio.) For example, the conventionally known wood chip cement board is made by mixing combustible wood with non-combustible cement at a weight ratio of about 1:1 and forming it into a board shape. , is recognized as a quasi-noncombustible material by JIS. The carbonization promotion of (g)) is as follows. When wood is heated, it thermally decomposes and generates flammable gas, which ignites and burns. However, the presence of phosphoric acid or boric acid promotes the thermal decomposition or carbonization of wood.The carbonized layer thus formed acts as a heat insulating layer and produces a flame retardant effect.
したがって、不溶性不燃性無機物がリン酸成分あるいは
ホウ酸成分を含む場合は、難燃効果が高いものとなる。Therefore, when the insoluble nonflammable inorganic substance contains a phosphoric acid component or a boric acid component, the flame retardant effect becomes high.
つぎに、木材の防腐・防虫化について説明する、菌類が
木材を腐敗させる際、まず、菌糸が木材内腔中へ侵入す

あっても良い。防虫についても防腐と同じであるが、防
虫効果のある薬剤を用いるのが好ましい。そのようなも
のとしては、たとえば、虫について消化性の悪い薬剤、
消化しない薬剤あるいは忌避作用のある薬剤があげられ
る。したがって、不溶性不燃性無機物を木材内腔中に含
ませれば、木材の防腐・防虫性を向上させうる。Next, we will explain how to prevent wood from rotting and insects.When fungi cause wood to rot, it is essential that mycelia first invade the inner cavity of the wood. However, if foreign matter is present in the internal cavity of the wood, mycelium cannot enter, and as a result, the wood becomes less susceptible to decay. The foreign matter in the internal cavity of the wood does not need to be a drug with a particular antiseptic effect, and may be anything as long as it does not serve as nutrients for fungi. Insect repelling is the same as preservative, but it is preferable to use a chemical that has an insect repellent effect. Such things include, for example, drugs that are difficult to digest for insects;
Examples include drugs that are not digested or drugs that have a repellent effect. Therefore, if an insoluble, noncombustible inorganic substance is included in the inner cavity of wood, the antiseptic and insect repellent properties of wood can be improved.
さらに、木材の寸法安定化について説明する。Furthermore, dimensional stabilization of wood will be explained.
木材を水で膨潤させておき、木材細胞壁中に何らかの物
質を固定できれば、バルク効果により、寸法安定化効果
が得られる。固定物質として、水に溶けにくい無機物も
使いうる。したがって、不溶性不燃性無機物を木材細胞
壁中に固定すれば、寸法安定性を向上させうる。If wood can be swollen with water and some substance can be fixed in the wood cell walls, a dimensional stabilizing effect can be obtained due to the bulk effect. Inorganic substances that are difficult to dissolve in water can also be used as immobilizing substances. Therefore, dimensional stability can be improved by fixing insoluble, non-combustible inorganic substances into wood cell walls.
しかし、一般に、不溶性不燃性無機物をそのまま水に分
散させ、この分散液からなる処理液を木材中に浸透させ
ようとしても、木材中にはほとんど水しか浸透して行か
ない。これは、つぎのような理由による。すなわち、木
材中に浸透する際に処理液が通過するべき経路の内、最
も狭い部分はビットメンプランであるが、ここにおける
空隙径が約0.1μmであるのに対し、分散した不溶性
不燃性無機物の粒子は、普通、0.1μ腸よりもかなり
大きいからである。However, in general, even if an insoluble, nonflammable inorganic substance is directly dispersed in water and a treatment liquid made of this dispersion is attempted to penetrate into wood, almost only water will penetrate into the wood. This is due to the following reasons. In other words, the narrowest part of the path that the treatment liquid must pass when penetrating into the wood is the bit membrane run, and the pore diameter here is approximately 0.1 μm, whereas the dispersed insoluble and nonflammable This is because mineral particles are usually much larger than 0.1 micron intestine.

同志を反応させて、不溶性不燃性無機物を生じさせる。Therefore, by impregnating wood with one of the two water-soluble inorganic aqueous solutions that produce insoluble non-flammable inorganic substances by mixing, and then impregnating the wood with the other, the insoluble non-flammable inorganic substances are dispersed and fixed within the wood structure. Efforts are being made to make this happen. This is because an aqueous solution can be impregnated into the structure of wood relatively easily. More specifically, for example, two aqueous solutions separately containing ions that can react to produce an insoluble, nonflammable inorganic substance,
It is made by dissolving water-soluble inorganic substances in water, and then impregnating the wood with a rainwater solution. Then, the ions react with each other in the wood to form an insoluble, nonflammable inorganic substance.

では木材の処理効率が悪く、生産性が非常に低い。この
ため、木材の処理効率の改善が求められていた。Conventionally, wood was impregnated with an aqueous solution by immersing the wood in an aqueous solution to cause an insoluble, nonflammable inorganic substance production reaction to take place. This method requires simple equipment and equipment, but on the other hand, the impregnation of the aqueous solution is slow and the reaction takes a long time, resulting in very low wood processing efficiency. For example, after being immersed for 24 hours in a first bath consisting of one of two water-soluble inorganic aqueous solutions that produce an insoluble nonflammable inorganic substance by mixing, the second bath is immersed for 24 hours in a second bath consisting of the other aqueous solution, and then The reaction that produces insoluble, nonflammable inorganic substances proceeds in the bath, but this method has poor wood processing efficiency and very low productivity. For this reason, there has been a need to improve wood processing efficiency.
この発明は、このような問題を解決するためになされた
ものであって、従来の製法よりも、木材の処理効率の高
い改質木材の製法を提供することを目的としている。The present invention was made to solve these problems, and an object of the present invention is to provide a method for producing modified wood that has higher wood processing efficiency than conventional production methods.

全体としての効率向上効果が大きくなかった。そこで、

。The inventors have conducted extensive research in an attempt to achieve the above object by shortening the soaking time of wood. In the case of treatment using the first bath, it was confirmed that if the wood to be treated was sufficiently saturated with water in advance, the soaking time could be reduced to 1/3, to 8 hours. However, the second
When it comes to treatment using a bath, the reaction progresses as the aqueous solution (drug) is impregnated, which prevents the aqueous solution from impregnating, so it turns out that the treatment still takes 24 hours.
The overall efficiency improvement effect was not large. Therefore,
The inventors conducted further research. As a result, they discovered that the production of insoluble and nonflammable inorganic substances can be promoted by applying physical stimuli such as ultrasonic vibration, microwave heating, and pressurization, and have now completed this invention.

であった。The impregnation rate of insoluble and nonflammable inorganic substances in the obtained modified wood was 45
~50%, and the impregnation rate was higher than when the veneer was immersed in the second bath for 24 hours. This is because the generation of insoluble nonflammable inorganic substances is promoted by microwaves, and the loss of ions impregnated into the veneer in the first bath to the second bath is suppressed by shortening the immersion time in the second bath. This is thought to be due to an increase in the amount of ions involved in the reaction. The modified wood obtained in this example has particularly excellent flame retardancy and dimensional stability, and has other properties that are equal to or better than those obtained by soaking the veneer in the second bath for 24 hours. That was it.
