Abstract
Description
本発明は、木材、紙又は布である可燃性基材を難燃化させるための難燃化処理水溶液に関し、更に詳しくは、人体に有害なホウ素(又はホウ素化合物)を含有しない難燃化処理水溶液に関する。
また、本発明は、かかる難燃化処理水溶液の製造方法、難燃化基材の製造方法、かかる難燃化処理水溶液を製造するための組成物やその製造方法に関する。
本発明の難燃化処理水溶液は、可燃性基材を含浸させることにより、可燃性基材に難燃性・防炎性を付加することができる水溶性の高い処理液である。
TECHNICAL FIELD The present invention relates to a flame retardant treatment aqueous solution for making a flammable substrate made of wood, paper or cloth flame retardant. More specifically, the present invention relates to a flame retardant treatment that does not contain boron (or boron compounds) harmful to the human body. It relates to an aqueous solution.
The present invention also relates to a method for producing such a flame retardant treatment aqueous solution, a method for producing a flame retardant substrate, a composition for producing such a flame retardant treatment aqueous solution, and a method for producing the same.
The flame retardant treatment aqueous solution of the present invention is a highly water-soluble treatment liquid that can add flame retardancy and flame resistance to a flammable substrate by impregnating the flammable substrate.
木材、布、紙等の可燃性基材に難燃性・防炎性を付与するための薬剤としては、ホウ素化合物を添加したもの等が知られている(特許文献1〜5)。 As chemicals for imparting flame retardancy and flameproofing properties to flammable base materials such as wood, cloth, paper, and the like, those containing a boron compound are known (Patent Documents 1 to 5).
ホウ素化合物は、難燃性・防炎性と防蟻性に優れているが、ホウ素化合物は、人体に対して、様々な悪影響を及ぼすことが知られている。
例えば、ホウ素化合物であるホウ酸は、咳、咽頭痛、眼の充血や痛み、吐き気、嘔吐、下痢、腹痛、皮疹、頭痛、痙攣等の症状を引き起こすことが指摘されている(非特許文献1)。
Boron compounds are excellent in flame retardancy, flameproofing and antproofing properties, but boron compounds are known to have various adverse effects on the human body.
For example, it has been pointed out that boric acid, which is a boron compound, causes symptoms such as cough, sore throat, eye redness and pain, nausea, vomiting, diarrhea, abdominal pain, skin rash, headache, convulsions (Non-patent Document 1). ).
2013年7月20日から適用されているヨーロッパの新しい玩具指令によれば、ホウ素(ホウ素化合物)が新たに有害物質の対象となり、玩具材料や玩具塗料からの人体への有害物質であるホウ素(ホウ素化合物)等の移行限度値が設定された。 According to the new European toy directive that has been applied since July 20, 2013, boron (boron compounds) is newly targeted for harmful substances, and boron (a harmful substance for toys from toy materials and toy paints) Transition limit values such as boron compounds) were set.
また、ホウ素(ホウ素化合物)は、それらが含浸された木材、布、紙が土壌中に廃棄された場合には、国の定めた土壌汚染対策法基準の土壌汚染と地下水汚染という環境負荷を引き起こす可能性のある物質であると規定されている。 Boron (boron compounds) also causes environmental impacts such as soil contamination and groundwater contamination in accordance with the national soil pollution control law standards when wood, cloth, and paper impregnated with them are discarded in the soil. It is defined as a possible substance.
ホウ素(ホウ素化合物)は、主にガラス繊維の原料に使用されている。このため、木材に含浸させると木材表面に白化現象が生じ、布や紙に含浸させるとゴワゴワ感が生じてしまう。 Boron (boron compound) is mainly used as a raw material for glass fibers. For this reason, when it is impregnated with wood, a whitening phenomenon occurs on the surface of the wood, and when it is impregnated with cloth or paper, a feeling of tingling occurs.
ホウ素(ホウ素化合物)は、水に対する溶解性が低い有害物質であり、木材に含浸する場合には、真空・加圧含浸法等の強制含浸法を用いることがほとんどであるが、その際に高度な圧力調整技術と高いコストが必要となる。 Boron (boron compound) is a harmful substance with low solubility in water, and when impregnating wood, forced impregnation methods such as vacuum and pressure impregnation methods are mostly used. Pressure regulation technology and high cost are required.
このため、ホウ素(ホウ素化合物)の代替となる成分を使用した難燃性・防炎性に優れた処理液の開発が望まれている。 For this reason, development of the processing liquid excellent in the flame retardance and flameproofness using the component which substitutes for boron (boron compound) is desired.
本発明は上記背景に鑑みてなされたものであり、その課題は、ホウ素(ホウ素化合物)を含有する従来の難燃・防炎剤の問題点を解決することのできる難燃化処理水溶液を提供することにある。 This invention is made | formed in view of the said background, The subject is providing the flame retardant treatment aqueous solution which can solve the problem of the conventional flame retardant and flame retardant containing boron (boron compound). There is to do.

また、ホウ素(ホウ素化合物)を含有する従来の難燃・防炎剤は、木材に対してホウ素(ホウ素化合物)に起因する白化現象、布や紙に対してゴワゴワ感を発生させるが、本発明の難燃化処理水溶液は、そのような問題をほとんど発生させない。
更に、本発明の難燃化処理水溶液は、水に対する溶解性が高く、粘度が低く、また、高性能な含浸促進剤を使用しているため、可燃性基材に浸透・含浸させやすい。このため、十分に可燃性基材に浸透・含浸させることができ、浸透・含浸コストの削減にも寄与する。
Specifically, the flame retardant treatment aqueous solution of the present invention does not use components that cause health problems and environmental loads such as boron (boron compounds), and uses only safe components.
Moreover, the conventional flame retardant / flameproofing agent containing boron (boron compound) causes a whitening phenomenon caused by boron (boron compound) to wood and a feeling of tingling to cloth or paper. This flame retardant treatment aqueous solution hardly causes such a problem.
Furthermore, since the flame retardant treatment aqueous solution of the present invention has high solubility in water, low viscosity, and uses a high-performance impregnation accelerator, it is easy to penetrate and impregnate a flammable substrate. For this reason, it is possible to sufficiently infiltrate and impregnate the flammable substrate, which contributes to reduction of the infiltration and impregnation costs.
本発明者は、上記の課題を解決すべく鋭意検討を重ねた結果、水溶性の高いリン酸二水素アンモニウムと硫酸アンモニウム、アンモニア、含浸促進剤を水に溶解・分散させることによって、難燃性・防炎性においてホウ素(ホウ素化合物)に劣らない上に、可燃性基材に浸透・含浸されやすい難燃化処理水溶液を作製することができることを見出して、本発明を完成するに至った。 As a result of intensive studies to solve the above-mentioned problems, the present inventor dissolved and dispersed a highly water-soluble ammonium dihydrogen phosphate, ammonium sulfate, ammonia, and an impregnation accelerator in water. The present inventors have found that a flame retardant treatment aqueous solution that can easily be infiltrated and impregnated into a combustible base material can be produced in addition to being inferior to boron (boron compound) in flame resistance.

浸透・含浸させる方法は浸漬、塗布、吹付、穿孔注入、含浸装置等による含浸等が挙げられる。特に、可燃性基材が木材の場合、木材の内部まで十分に成分を浸透・含浸させることにより、本発明の効果が発揮されやすくなるので、含浸装置等による含浸や穿孔注入が好ましい。 Examples of the impregnation / impregnation method include dipping, coating, spraying, perforation injection, impregnation with an impregnation apparatus, and the like. In particular, when the flammable base material is wood, the effect of the present invention can be easily exerted by sufficiently infiltrating and impregnating the components up to the inside of the wood, so that impregnation or perforation injection with an impregnation apparatus or the like is preferable.
浸漬の場合、浸漬時間は30分以上1週間以下が好ましく、1時間以上2日以下がより好ましく、2時間以上1日以下が特に好ましい。
浸漬時間の下限が上記以上であると、可燃性基材の内部まで十分に成分が浸透し、得られる難燃化基材の難燃性が優れたものとなる。また、浸漬時間の下限が上記以下であると、生産性が十分となる(浸漬時間の上限を上記以上にしても、難燃化基材の性能は優れたものとはならず、無意味である)。
In the case of immersion, the immersion time is preferably from 30 minutes to 1 week, more preferably from 1 hour to 2 days, and particularly preferably from 2 hours to 1 day.
When the lower limit of the immersion time is not less than the above, the component sufficiently penetrates to the inside of the combustible substrate, and the flame retardancy of the obtained flame retardant substrate is excellent. Further, if the lower limit of the immersion time is less than or equal to the above, the productivity is sufficient (even if the upper limit of the immersion time is more than the above, the performance of the flame retardant substrate is not excellent, meaningless is there).
また、浸漬は1回行うのではなく、途中で可燃性基材をいったん取り出し乾燥させ、複数回に分けて浸漬を行うのも好ましい。浸漬の際に、気泡の発生等により、局所的に難燃成分が浸透しにくい部位が生ずることがあるが、複数回に分けて浸漬すれば、このようなことを防止することができる。 Moreover, it is preferable not to perform immersion once, but to take out a combustible base material in the middle, to dry, and to immerse in multiple steps. At the time of immersion, there may be a site where the flame retardant component is difficult to penetrate locally due to the generation of bubbles or the like, but this can be prevented by immersing in multiple times.
浸漬後の乾燥は、自然乾燥が好ましいが、熱風乾燥機等による強制乾燥でもよい。
自然乾燥の場合、乾燥時間は、30分以上1週間以下が好ましく、1時間以上2日以下がより好ましく、2時間以上1日以下が特に好ましい。
強制乾燥の場合、乾燥時間は、1分以上8時間以下が好ましく、2分以上3時間以下がより好ましく、3分以上1時間以下が特に好ましい。
The drying after immersion is preferably natural drying, but may be forced drying with a hot air dryer or the like.
In the case of natural drying, the drying time is preferably from 30 minutes to 1 week, more preferably from 1 hour to 2 days, and particularly preferably from 2 hours to 1 day.
In the case of forced drying, the drying time is preferably from 1 minute to 8 hours, more preferably from 2 minutes to 3 hours, and particularly preferably from 3 minutes to 1 hour.
表1に、本発明の難燃化処理水溶液の一例について、一般財団法人日本文化用品安全試験所にて行なわれた有害17元素19項目に関する試験結果を示す。本発明の難燃化処理水溶液は、EN71−3(2013年7月20日よりEUで玩具の安全を対象に新しく適用開始された基準)の規格値を全てで下回っている。本発明の難燃化処理水溶液は、ホウ素(ホウ素化合物)を含んでいないため、溶解性ホウ素も規格値をはるかに下回る数値であった。 Table 1 shows the results of tests on 19 items of harmful 17 elements conducted at the Japan Cultural Goods Safety Laboratory for an example of the flame retardant treatment aqueous solution of the present invention.

Since the flame retardant treatment aqueous solution of the present invention does not contain boron (boron compound), the soluble boron was also a numerical value far below the standard value.
また、表1に示した本発明の難燃化処理水溶液の一例は、室内濃度指針値が設定された13物質(ホルムアルデヒド、アセトアルデヒド、トルエン、キシレン、エチルベンゼン、スチレン、パラジクロロベンゼン、テトラデカン、クロルピリホス、フェノブカルブ、ダイアジノン、フタル酸ジ−n−ブチル、フタル酸ジ−2−エチルヘキシル)を一切含んでおらず、社団法人日本しろあり対策協会と公益財団法人日本木材保存協会にて認定された健康障害と環境負荷を引き起こさない処理液である。 In addition, examples of the flame retardant treatment aqueous solution of the present invention shown in Table 1 include 13 substances (formaldehyde, acetaldehyde, toluene, xylene, ethylbenzene, styrene, paradichlorobenzene, tetradecane, chlorpyrifos, fenocarb, which are set with indoor concentration guideline values. , Diazinon, di-n-butyl phthalate, di-2-ethylhexyl phthalate), and health hazards and environmental impacts certified by the Japan Shirori Countermeasure Association and the Japan Wood Conservation Association It is a processing solution that does not cause
<作用・原理>
本発明の難燃化処理水溶液が優れた難燃性を示す作用・原理は明らかではないが、以下のことが考えられる。ただし本発明は、以下の作用効果の範囲に限定されるわけではない。
<Action and principle>
Although the action and principle of the flame retardant treatment aqueous solution of the present invention exhibiting excellent flame retardancy are not clear, the following can be considered. However, the present invention is not limited to the range of the following effects.
本発明の難燃化処理水溶液は、燃焼中に有機物の炭化を著しく促進して可燃性の炭素含有気体の生成を減少させ、燃焼速度の遅い炭素の生成量を増加させることにより、可燃性基材の燃焼を抑制していると考えられる。
具体的には、難燃成分(リン酸二水素アンモニウム、硫酸アンモニウム)が、可燃性基材の燃焼時に熱分解することで窒素ガスを発生し、この窒素ガスが酸素を遮断し燃焼を抑制しているものと考えられる。また、難燃成分が可燃性基材表面で炭素との混合物膜を生成し、燃焼を抑制しているものと考えられる。
また、難燃成分が分解することで生成するアンモニウムイオン(NH4 +)、リン酸水素イオン(HPO4 2−)、リン酸二水素イオン(H2PO4 −)等による負触媒効果も、燃焼の抑制に寄与しているものと考えられる。
The flame retardant treatment aqueous solution of the present invention significantly promotes carbonization of organic matter during combustion, reduces the generation of flammable carbon-containing gas, and increases the amount of carbon generated at a low combustion rate, thereby increasing the flammable group. It is thought that the combustion of the material is suppressed.
Specifically, flame retardant components (ammonium dihydrogen phosphate, ammonium sulfate) generate nitrogen gas by thermal decomposition during combustion of the flammable base material, and this nitrogen gas blocks oxygen and suppresses combustion. It is thought that there is. In addition, it is considered that the flame retardant component forms a mixture film with carbon on the surface of the flammable substrate and suppresses combustion.
In addition, the negative catalytic effect by ammonium ions (NH 4 + ), hydrogen phosphate ions (HPO 4 2− ), dihydrogen phosphate ions (H 2 PO 4 − ), etc. produced by decomposition of the flame retardant component, This is thought to contribute to the suppression of combustion.

<Example 1>
Using a Ryukyu pine plate as a sample, the flame retardancy performance of the flame retardant treatment aqueous solution of the present invention was tested. Ryukyu pine is said to have a higher density than other woods, and it is difficult for the components of the liquid agent to penetrate and impregnate.
調製例1で調製した溶液1を、バットの中に充填し、10cm×10cm×1.5cmのリュウキュウマツの板を12時間浸漬した。その後、板を取り出して自然乾燥させた後、再び、溶液1に12時間浸漬した。その後、再び板を取り出し、自然乾燥させた。 The solution 1 prepared in Preparation Example 1 was filled in a vat and a 10 cm × 10 cm × 1.5 cm Ryukyu pine plate was immersed for 12 hours. Thereafter, the plate was taken out and naturally dried, and then again immersed in the solution 1 for 12 hours. Thereafter, the plate was taken out again and allowed to air dry.
上記処理前の板の質量は110.1gであったのに対し、上記処理後の板の質量は118.6gであり、難燃化処理水溶液の成分が含浸することにより、板の質量が8.5g増加していた。 The mass of the plate before the treatment was 110.1 g, whereas the mass of the plate after the treatment was 118.6 g, and the weight of the plate was 8 by being impregnated with the component of the flame retardant treatment aqueous solution. It was increased by 5g.
自然乾燥させた板に対して、使用ガスはプロパン、炎先端と試験体の距離は5cm、炎の先端温度は1000℃前後として、火炎照射した。板の裏面(炎の反対側)には、温度計を設置し、50秒間隔で温度を測定した。
火炎照射後8分後の裏面の温度は75℃であり、その後も裏面の温度に大きな上昇はなく、炎が裏面に貫通する兆しは無かった。
The naturally dried plate was irradiated with flame with propane as the gas used, the distance between the flame tip and the test piece being 5 cm, and the flame tip temperature being around 1000 ° C. A thermometer was installed on the back surface (opposite side of the flame) of the plate, and the temperature was measured at intervals of 50 seconds.
The temperature of the back surface 8 minutes after the flame irradiation was 75 ° C., and there was no significant increase in the temperature of the back surface, and there was no sign that the flame penetrated the back surface.
