Abstract
Description
本発明は、木質材料を改質するための化学処理薬剤組成物、それを用いた改質木質材料の製造方法、有機溶媒の再生方法及び化学処理薬剤組成物の製造方法に関する。 The present invention relates to a chemically treated chemical composition for modifying a wood material, a method for producing a modified wood material using the same, a method for regenerating an organic solvent, and a method for producing a chemically treated chemical composition.
木質材料を改質するための化学処理薬剤、例えば、防腐剤、防虫剤、防カビ剤及び難燃剤等に用いる有機溶媒としては、塩化メチレンが従来用いられている。これは、塩化メチレンに対する有効成分の溶解性が良好であること、塩化メチレンが本邦の消防法に定められた危険物に該当しないこと、単価が安いこと等に起因する。 Methylene chloride has been conventionally used as an organic solvent used for chemical treatment agents for modifying wood materials, for example, preservatives, insect repellents, fungicides, flame retardants and the like. This is because the active ingredient has good solubility in methylene chloride, methylene chloride does not fall under the dangerous goods stipulated in the Fire Service Act of Japan, and the unit price is low.
近年、大気汚染防止法や労働安全衛生法等の法規制によって、改質木材業界では、塩素系溶剤の使用が難しくなってきている。このため、塩化メチレンに替わる有機溶媒として、高価なフッ素系溶剤をリサイクルしながら使用する試みがなされている。例えば、特許文献１においては、改質有効成分、有効成分を溶解する有機溶媒、及び有機塩化合物を含有し、且つ水の含有量が５質量％以下である木質材料を改質するための化学処理薬剤組成物が記載され、塩化メチレンの他にＣＦＣ−１１、ＨＣＦＣ−２２５等のフロン系溶媒や、ハイドロフルオロカーボン（ＨＦＣ）類、ハイドロフルオロエーテル（ＨＦＥ）類等の代替フロン系溶媒を用いることが記載されている。 In recent years, the use of chlorine-based solvents has become difficult in the modified wood industry due to laws and regulations such as the Air Pollution Control Law and the Industrial Safety and Health Law. For this reason, attempts have been made to use an expensive fluorine-based solvent as an organic solvent in place of methylene chloride while recycling it. For example, in Patent Document 1, a chemistry for modifying a wood material containing a modified active ingredient, an organic solvent for dissolving the active ingredient, and an organic salt compound and having a water content of 5% by mass or less. The treatment drug composition is described, and in addition to methylene chloride, a chlorofluorocarbon solvent such as CFC-11 or HCFC-225 or an alternative chlorofluorocarbon solvent such as hydrofluorocarbon (HFC) or hydrofluoroether (HFE) is used. Is described.
しかし、フッ素系溶剤においては、ＨＦＣ類、ＨＦＥ類等の代替フロン系溶媒では地球温暖化係数（ＧＷＰ）が高く、地球環境への影響が懸念される。 However, among fluorocarbon solvents, alternative chlorofluorocarbon solvents such as HFCs and HFEs have a high global warming potential (GWP), and there is concern about the impact on the global environment.
本発明は、地球環境への影響が少ない、木質材料を改質するための化学処理薬剤組成物を提供することを目的の一つとする。または、その化学処理薬剤組成物を用いた改質木質材料の製造方法を提供することを目的の一つとする。または、化学処理薬剤組成物に用いる有機溶媒の再生方法を提供することを目的の一つとする。または、化学処理薬剤組成物の製造方法を提供することを目的の一つとする。 One of the objects of the present invention is to provide a chemically treated chemical composition for modifying wood-based materials, which has little impact on the global environment. Another object of the present invention is to provide a method for producing a modified wood-based material using the chemically treated chemical composition. Another object of the present invention is to provide a method for regenerating an organic solvent used in a chemically treated drug composition. Alternatively, one of the purposes is to provide a method for producing a chemically treated drug composition.

As the organic solvent other than the hydrofluoroolefins, one or more can be selected from the known organic solvents used in the chemically treated chemical composition for modifying the wood material. For example, aliphatic hydrocarbons such as n-hexane, n-heptane and kerosine; aromatic hydrocarbons such as benzene, toluene and xylene; chlorinated hydrocarbons such as methylene chloride and trichloroethylene; CFC-11, HCFC- Flon-based solvent such as 225; Alternative freon-based solvent such as HFC and HFE; Nitrohydrocarbons such as nitromethane and nitroethane; Nitrigens such as acetonitrile; Ketones such as acetone and methyl ethyl ketone; Glycol ether derivatives such as tetrahydrofuran, propylene glycol monopropyl ether and dipropylene glycol monomethyl ether acetate; nitrogen-containing ring compounds such as n-methylpyrrolidone and 1,3-dimethyl-2-imidazolidinone can be mentioned. However, it is not limited to these. In one embodiment, the chemically treated drug composition may contain methylene chloride as an organic solvent other than hydrofluoroolefins. From the viewpoint of suppressing the influence on the global environment, the amount of the organic solvent other than the hydrofluoroolefins is preferably significantly smaller than that of the hydrofluoroolefins contained in the chemical treatment drug composition, for example, chemical treatment. The content of the organic solvent other than the hydrofluoroolefins is 50% by weight or less, preferably 20% by weight or less, based on 100% by weight of the organic solvent contained in the drug composition.
一実施形態において、有効成分は、ハイドロフルオロオレフィン類１００重量％に対して、０．０１重量％〜５重量％含有され、０．１重量％〜２重量％含有されることが好ましい。有効成分の含有量をこれらの範囲に調製することにより、有効成分の木材への良好な浸透性と、化学処理薬剤組成物の十分な効果が得られるとともに、有機溶媒であるハイドロフルオロオレフィン類の回収促進効果が得られる。 In one embodiment, the active ingredient is preferably contained in an amount of 0.01% by weight to 5% by weight, preferably 0.1% by weight to 2% by weight, based on 100% by weight of the hydrofluoroolefins.

A recovery promoting effect can be obtained.
一実施形態において、化学処理薬剤組成物は、水を実質上含有しないことが好ましい。水を含有した化学処理薬剤組成物を木質材料に注入すると、木質材料の含水率が著しく上昇して、木質材料の寸法変動を引き起こす。このため、化学処理薬剤組成物に水が含まれる場合、木質材料の寸法変動を引き起こさない含有量であることが好ましく、化学処理薬剤組成物１００重量％に対して、水の含有量は５重量％以下であり、３重量％以下であることが好ましい。 In one embodiment, the chemically treated chemical composition preferably contains substantially no water. When a chemically treated chemical composition containing water is injected into a wood-based material, the water content of the wood-based material is significantly increased, causing dimensional variation of the wood-based material. Therefore, when water is contained in the chemically treated chemical composition, it is preferable that the content does not cause dimensional fluctuation of the wood-based material, and the content of water is 5% by weight with respect to 100% by weight of the chemically treated chemical composition. % Or less, preferably 3% by weight or less.

［改質木質材料の製造方法］
上述した化学処理薬剤組成物を用いて、改質木質材料を製造することができる。図１は、改質木質材料の製造方法を説明するフロー図である。改質木質材料の製造方法は、例えば、木質材料を減圧下で乾燥させる工程（Ｓ１０１）、木質材料に化学処理薬剤組成物を塗布、含侵または注入する工程（Ｓ１０３）、及び木質材料中の有機溶媒を揮発させる工程（Ｓ１０５）を含む。
[Manufacturing method of modified wood-based materials]
A modified wood-based material can be produced using the chemically treated chemical composition described above. FIG. 1 is a flow chart illustrating a method for producing a modified wood-based material. The method for producing the modified wood-based material includes, for example, a step of drying the wood-based material under reduced pressure (S101), a step of applying, impregnating or injecting a chemically treated chemical composition into the wood-based material (S103), and in the wood-based material. The step (S105) of volatilizing the organic solvent is included.
工程Ｓ１０１は、木質材料を大気圧に対する相対圧力であるゲージ圧で−０．００１ＭＰａＧ〜−０．１０１ＭＰａＧの減圧環境下で乾燥させる工程である。工程Ｓ１０１により、木質材料の水分含有量が減少し、化学処理薬剤組成物が浸透しやすくなるとともに、木質材料が水分を含有することによる製造後の木質材料の寸法変動を抑制することができる。木質材料の乾燥温度は、１０℃〜５０℃で行うことができ、１０℃〜４０℃で行うことが好ましい。なお、十分に乾燥した木材を使用する場合には、工程Ｓ１０１は、任意の工程である。 Step S101 is a step of drying the wood-based material in a reduced pressure environment of −0.001 MPaG to −0.101 MPaG at a gauge pressure which is a relative pressure with respect to atmospheric pressure. By step S101, the water content of the wood-based material is reduced, the chemically treated chemical composition is easily permeated, and the dimensional fluctuation of the wood-based material after production due to the water content of the wood-based material can be suppressed. The drying temperature of the wood-based material can be 10 ° C. to 50 ° C., preferably 10 ° C. to 40 ° C. When sufficiently dried wood is used, step S101 is an arbitrary step.
工程Ｓ１０３は、木質材料に化学処理薬剤組成物を接触させる工程であり、塗布、含侵または注入することにより実施される。木質材料と化学処理薬剤組成物との接触は、大気圧下で行うことができる。また、化学処理薬剤組成物を木質材料に接触させる温度は１０℃〜１００℃であり、２０℃〜５０℃であることが好ましい。一実施形態において、加圧下で化学処理薬剤組成物を木質材料に接触させることが好ましい。例えば、化学処理薬剤組成物を塗布した木質材料を加圧する、又は加圧下で化学処理薬剤組成物を木質材料に含侵させてもよい。木質材料を０．１ＭＰａＧ〜１．０ＭＰａＧで加圧することが好ましい。加圧時間は、木質材料が所定量の化学処理薬剤組成物を含有すれば特に限定されず、適宜設定可能である。 Step S103 is a step of bringing the chemically treated chemical composition into contact with the wood material, and is carried out by coating, impregnating or injecting. The contact between the wood-based material and the chemically treated drug composition can be carried out under atmospheric pressure. The temperature at which the chemically treated chemical composition is brought into contact with the wood material is 10 ° C to 100 ° C, preferably 20 ° C to 50 ° C. In one embodiment, it is preferable to bring the chemically treated chemical composition into contact with the wood-based material under pressure. For example, the wood-based material coated with the chemically-treated drug composition may be pressurized, or the wood-based material may be impregnated with the chemically-treated drug composition under pressure. It is preferable to pressurize the wood material at 0.1 MPaG to 1.0 MPaG. The pressurization time is not particularly limited as long as the wood-based material contains a predetermined amount of the chemically treated chemical composition, and can be appropriately set.
工程Ｓ１０５は、木質材料中の有機溶媒を揮発させて、有効成分を木質材料中に配置又は固定化する工程である。工程Ｓ１０５は、木質材料中の有機溶媒の少なくとも一部を除去する工程であって、必ずしも木質材料中の有機溶媒を全て除去することを意図するものではないが、木質材料中の全て有機溶媒が除去されることが好ましい。例えば、木質材料中の有機溶媒は、９０重量％以上が除去されるのが好ましく、９５重量％以上が除去されるのがより好ましく、９９重量％以上が除去されるのが特に好ましい。有機溶媒を除去するための方法は、特に限定されないが、例えば、加温による乾燥方法、熱風乾燥、減圧乾燥、又は大気雰囲気中に放置する乾燥方法が挙げられるが、これらに限定されるものではない。また、有機溶媒を除去する際の温度は、２０℃〜１００℃であり、３０℃〜８０℃が好ましい。有機溶媒を除去するための時間は、木質材料が所定量の有機溶媒が除去されれば特に限定されず、適宜設定可能である。 Step S105 is a step of volatilizing the organic solvent in the wood-based material to dispose or immobilize the active ingredient in the wood-based material. Step S105 is a step of removing at least a part of the organic solvent in the wood-based material, and is not necessarily intended to remove all the organic solvent in the wood-based material, but all the organic solvents in the wood-based material are used. It is preferably removed. For example, 90% by weight or more of the organic solvent in the wood-based material is preferably removed, 95% by weight or more is more preferably removed, and 99% by weight or more is particularly preferably removed. The method for removing the organic solvent is not particularly limited, and examples thereof include a drying method by heating, a hot air drying, a vacuum drying, and a drying method of leaving in an air atmosphere, but the method is not limited thereto. Absent. The temperature at which the organic solvent is removed is 20 ° C to 100 ° C, preferably 30 ° C to 80 ° C. The time for removing the organic solvent is not particularly limited as long as a predetermined amount of the organic solvent is removed from the wood-based material, and can be appropriately set.
本発明に係る化学処理薬剤組成物を用いることにより、地球環境への影響を低減して、改質木質材料を製造することができる。 By using the chemically treated chemical composition according to the present invention, it is possible to produce a modified wood-based material by reducing the influence on the global environment.
［有機溶媒の再生方法］
上述した改質木質材料の製造方法において木質材料から除去された有機溶媒は、ハイドロフルオロオレフィン類を含むため、回収して再利用することが好ましい。図２は、有機溶媒の再生方法を説明するフロー図である。有機溶媒の再生方法は、例えば、揮発させた有機溶媒を回収する工程（Ｓ２０１）、回収した有機溶媒をろ過する工程（Ｓ２０３）、ろ過した有機溶媒を精製する工程（Ｓ２０５）、及び精製した有機溶媒の組成を調整する工程（Ｓ２０７）を含む。
[Regeneration method of organic solvent]
Since the organic solvent removed from the wood-based material in the above-mentioned method for producing a modified wood-based material contains hydrofluoroolefins, it is preferable to recover and reuse it. FIG. 2 is a flow chart illustrating a method for regenerating the organic solvent. The method for regenerating the organic solvent is, for example, a step of recovering the volatilized organic solvent (S201), a step of filtering the recovered organic solvent (S203), a step of purifying the filtered organic solvent (S205), and the purified organic. The step (S207) of adjusting the composition of the solvent is included.
工程Ｓ２０１は、揮発させた有機溶媒を回収する工程であって、有機溶媒を含む気体を回収する、又は有機溶媒を含む気体を凝集させて、液化した有機溶媒を回収する工程である。例えば、工程Ｓ２０１は、有機溶媒を含む気体をタンクに貯蔵してもよく、貯蔵せずに、精製工程に有機溶媒を含む気体を供給してもよい。また、有機溶媒を含む気体を凝集器で液化させてタンクに貯蔵してもよく、液化した有機溶媒を精製工程に供給してもよい。有機溶媒を液化させて回収することにより、改質木質材料の製造プラントとの外部にある有機溶媒の再生に搬送することができ、その輸送コストも低減することができる。 Step S201 is a step of recovering the volatilized organic solvent, which is a step of recovering the gas containing the organic solvent or aggregating the gas containing the organic solvent to recover the liquefied organic solvent. For example, in step S201, the gas containing the organic solvent may be stored in the tank, or the gas containing the organic solvent may be supplied to the purification step without storing the gas. Further, the gas containing the organic solvent may be liquefied by an aggregator and stored in the tank, or the liquefied organic solvent may be supplied to the purification step. By liquefying and recovering the organic solvent, it can be transported to the regeneration of the organic solvent outside the production plant of the modified wood-based material, and the transportation cost can be reduced.
工程Ｓ２０３は、回収した有機溶媒をろ過して、有機溶媒に含まれるゴミや埃のような固形成分を除去する工程である。例えば、メッシュやフィルタを用いて、有機溶媒をろ過することができる。なお、工程Ｓ２０３は任意の工程であって、精製工程に供給するのに支障をきたさなければ実施しなくてもよい。 Step S203 is a step of filtering the recovered organic solvent to remove solid components such as dust and dirt contained in the organic solvent. For example, the organic solvent can be filtered using a mesh or a filter. Note that step S203 is an arbitrary step and may not be carried out as long as it does not interfere with the supply to the purification step.
工程Ｓ２０５は、改質木質材料の製造により有機溶媒に混入した木質材料に由来する成分や水分を除去する工程であって、例えば、蒸留工程及び脱水工程を備える。したがって、有機溶媒に含まれるハイドロフルオロオレフィン類とハイドロフルオロオレフィン類以外の有機溶媒を完全に分離する必要はない。また、有機溶媒が２種類以上のハイドロフルオロオレフィンを含む場合や、ハイドロフルオロオレフィン類以外の有機溶媒を２種類以上含む場合にも、それぞれの成分を単離する必要はない。なお、必要に応じて、有機溶媒に含まれる成分を単離して回収してもよい。また、精製した有機溶媒をゼオライトや活性炭等の多孔質体と接触させて脱水処理を行ってもよい。 Step S205 is a step of removing components and water derived from the wood-based material mixed in the organic solvent by producing the modified wood-based material, and includes, for example, a distillation step and a dehydration step. Therefore, it is not necessary to completely separate the hydrofluoroolefins contained in the organic solvent and the organic solvent other than the hydrofluoroolefins. Further, when the organic solvent contains two or more kinds of hydrofluoroolefins or when two or more kinds of organic solvents other than hydrofluoroolefins are contained, it is not necessary to isolate each component. If necessary, the components contained in the organic solvent may be isolated and recovered. Further, the purified organic solvent may be brought into contact with a porous body such as zeolite or activated carbon for dehydration treatment.
工程Ｓ２０７は、有機溶媒を再利用するために、組成を調整する工程である。例えば、精製した有機溶媒が所定の組成比となるように、不足した構成成分を添加してもよく、所定の組成比となるように、単離して回収した有機溶媒の構成成分を調合してもよい。なお、工程Ｓ２０７は任意の工程であって、有機溶媒が１種類のハイドロフルオロオレフィンから構成されている場合には実施されない。また、再生された有機溶媒は、改質木質材料の製造に用いられた化学処理薬剤組成物に含まれる有機溶媒の組成と同じであってもよく、異なっていてもよい。異なる組成で再生された有機溶媒は、異なる化学処理薬剤組成物の溶媒として用いてもよい。 Step S207 is a step of adjusting the composition in order to reuse the organic solvent. For example, the insufficient constituent components may be added so that the purified organic solvent has a predetermined composition ratio, and the constituent components of the isolated and recovered organic solvent are prepared so as to have a predetermined composition ratio. May be good. Note that step S207 is an arbitrary step and is not carried out when the organic solvent is composed of one kind of hydrofluoroolefin. Further, the regenerated organic solvent may be the same as or different from the composition of the organic solvent contained in the chemically treated chemical composition used for producing the modified wood-based material. Organic solvents regenerated with different compositions may be used as solvents for different chemically treated drug compositions.

＜改質木質材料の製造＞
ガラス製サンプル瓶（５０ｃｃ、外径４０ｍｍ）に、上記で調製した化学処理薬剤組成物を５０ｇ入れた。厚さ５ｍｍ、０．８ｇのスギの木材片を耐圧密閉容器に入れ、１ｋＰａにて４時間減圧乾燥させた。この木材片を大気圧に解放した後、２５℃にて、化学処理薬剤組成物に１時間浸漬させた。浸漬後、化学処理薬剤組成物から取り出した木材片を、２５℃、大気圧で静置乾燥して、木材片の経時的な重量変化（％）を計測した。静置後６４時間経過した時点で、木材片を耐圧密閉容器に入れ、１ｋＰａにて２時間減圧乾燥させて、実施例の改質木質材料を調製した。各実施例の改質木質材料における重量変化を表２に示す。
50 g of the chemically treated drug composition prepared above was placed in a glass sample bottle (50 cc, outer diameter 40 mm). A piece of wood of Sugi having a thickness of 5 mm and 0.8 g was placed in a pressure-resistant airtight container and dried under reduced pressure at 1 kPa for 4 hours. After releasing this piece of wood to atmospheric pressure, it was immersed in the chemically treated chemical composition for 1 hour at 25 ° C. After the immersion, the wood pieces taken out from the chemically treated chemical composition were allowed to stand and dried at 25 ° C. and atmospheric pressure, and the weight change (%) of the wood pieces with time was measured. When 64 hours had passed after standing, the wood pieces were placed in a pressure-resistant airtight container and dried under reduced pressure at 1 kPa for 2 hours to prepare the modified wood-based material of the example. Table 2 shows the weight change in the modified wood-based material of each example.
［参考例］
実施例で調製した木材処理溶液の代わりに、有機溶媒のみを用いたこと以外は、実施例と同様の方法により改質木質材料を調製した。改質木質材料の調製において、浸漬前の木材片の重量を基準として、木材片の経時的な重量変化（％）を計測した。また、静置後４０時間経過した時点で、木材片を耐圧密閉容器に入れ、１ｋＰａにて２時間減圧乾燥させた。各参考例の改質木質材料における重量変化を表３に示す。
A modified wood-based material was prepared by the same method as in Examples except that only an organic solvent was used instead of the wood treatment solution prepared in Examples. In the preparation of the modified wood-based material, the weight change (%) of the wood piece over time was measured based on the weight of the wood piece before immersion. Further, when 40 hours had passed after standing, the wood pieces were placed in a pressure-resistant airtight container and dried under reduced pressure at 1 kPa for 2 hours. Table 3 shows the weight change in the modified wood-based material of each reference example.
実施例および参考例の結果から、有機溶媒は木材片から揮発する一方、有効成分は木材片の内部に残留することが明らかとなった。また、有機溶媒としてＨＣＦＯ−１２３３ｙｄ、ＨＣＦＯ−１２３３ｚｄ、ＨＣＦＯ−１２２３ｘｄを用いる場合、ＨＣＦＯ−２５４６ｍｚｘｚｚと比べて短時間で揮発することが明らかとなった。また、実施例及び参考例のいずれにおいても、乾燥後の木材片には寸法の変化はなく、変色も起こらなかった。 From the results of Examples and Reference Examples, it was clarified that the organic solvent volatilized from the piece of wood, while the active ingredient remained inside the piece of wood. Further, it was revealed that when HCFO-1233yd, HCFO-1233zzd, and HCFO-1223xd were used as the organic solvent, they volatilized in a shorter time than HCFO-2546 mzzxzz. Moreover, in both the examples and the reference examples, there was no change in the dimensions of the dried wood pieces and no discoloration occurred.
