【０００１】
【産業上の利用分野】本発明は、メチルハイドロジェンポリシロキサン（以下Ｈオイルという。）等に代表される反応性シリコーンによる撥水被覆を解除する方法を提供し、その方法を用いて、粉末消火剤として広く使用されている、シリコーン撥水処理されたリン酸二水素アンモニウムに本来の水溶性を回復させて、リン酸及びアンモニア性窒素肥料として再利用する方法を提供しようとするものである。
【０００２】
【従来の技術】シリコーン撥水被覆は加熱によって解除できることが知られている。しかし、前記リン酸二水素アンモニウムのように、熱によって容易に変質する物質に施された撥水被覆を解除する方法としては不適当である。その為、粉末消火器に充填されたリン酸二水素アンモニウムのシリコーン処理物は、使用期限が過ぎると廃棄されていた。
【０００３】
【発明が解決しようとする課題】本発明は熱を用いず、リン酸二水素アンモニウムを変質させることなく、容易かつ速やかにシリコーン撥水被覆を解除し、肥料として再利用する方法を提供することを目的とする。
【０００４】
【課題を解決するための手段】シリコーン被覆されたリン酸二水素アンモニウム粉末にアルカリを含むアルコールを浸潤させ、シリコーン撥水被覆を解除する。
【０００５】
【作用】Ｈオイルにアルカリを含むアルコールを加えると、Ｈオイルは水素ガスを発生しながら水に対して濡れ性を持つ樹脂状の物質に変化する。アルカリは水酸化ナトリウム、水酸化カルシウム、ケイ酸ナトリウム等、アルコールはメタノール、エタノール、プロパノール等で、樹脂状物質の硬さ、色に違いはあるものの、どの組み合わせでも同様の変化を生ずる。この反応に着目し、シリコーン撥水被覆の解除に利用することとした。
【０００６】
【実施例】本発明の実施例では、アルコールには安価で入手し易いメタノールを、アルカリには、植物の成育に有用な元素を含むという理由から水酸化カリウムを、被処理物にはヤマトＡＢＣ粉末消火剤の使用期限を過ぎたもの（以下廃粉末消火剤という。）を使用した。工業用メタノール（９９．９％）１，０００ｍｌに水酸化カリウム２ｇを溶かして処理薬とする。１０ｋｇの廃粉末消火剤を厚手のビニール袋に入れ、処理薬を注ぎ密封した後１８ｌ缶に納め、蓋をして２４時間放置した。処理後物を取り出し水に溶かしてみると、処理前は全く水に溶けなかった廃粉末消火剤が容易に水に溶け、ピンク色の水溶液となった。
【０００７】撥水性を与え、流動性を向上させる為にシリコーン処理された粉末消火剤は、僅かの風にも粉塵となって舞い上がる為取り扱いが困難で、攪拌などの工程には不向きである。本発明の方法は単に被処理物に注ぐだけで、アルコールの高い浸透性に任せて反応を待つのみであるので、作業は極めて容易で粉塵の発生も無い。
【０００８】また、メタノールの水に対する溶解度は１００％であるので、反応時間に急を要しなければ、前記処理薬のメタノールに水を加えて、費用の削減を図ってもよい。
【０００９】
【発明の効果】とうもろこしを栽培し、一般の肥料（アンモニア性窒素１５．０％、可溶性リン酸１５．０％、く溶性加里１０．０％を含む化成肥料）を使用したもの、本発明によって得た廃粉末消火剤処理後物を肥料として使用したもの、施肥しないものの３種類の畝を作り、効果を比較した。施肥しないものの成育が不良だったのは勿論だが、本発明の再生肥料を使用したものの成育と結実状況は一般の肥料を使用したものに比べ全く遜色が無かった。[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a method for releasing a water-repellent coating with a reactive silicone represented by methyl hydrogen polysiloxane (hereinafter referred to as H oil) and the like. An object of the present invention is to provide a method of restoring the original water solubility of silicone water-repellent ammonium dihydrogen phosphate, which is widely used as a fire extinguishing agent, to reuse it as phosphoric acid and ammoniacal nitrogen fertilizer. .
[0002]
2. Description of the Related Art It is known that a silicone water-repellent coating can be released by heating. However, it is unsuitable as a method for releasing the water-repellent coating applied to a substance which is easily deteriorated by heat, such as the above ammonium dihydrogen phosphate. Therefore, the silicone-treated ammonium dihydrogen phosphate filled in the powder fire extinguisher has been discarded after the expiration date.
[0003]
SUMMARY OF THE INVENTION The present invention provides a method for easily and quickly releasing a silicone water-repellent coating without heat and without altering ammonium dihydrogen phosphate, and reusing it as fertilizer. With the goal.
[0004]
An alcohol containing alkali is infiltrated into a silicone-coated ammonium dihydrogen phosphate powder to release the silicone water-repellent coating.
[0005]
When an alcohol containing an alkali is added to H oil, the H oil is converted into a resinous substance having wettability with water while generating hydrogen gas. Alkali is sodium hydroxide, calcium hydroxide, sodium silicate and the like, and alcohol is methanol, ethanol, propanol and the like. Although the hardness and color of the resinous substance are different, the same change occurs in any combination. Focusing on this reaction, it was decided to use it for releasing the silicone water-repellent coating.
[0006]
In the embodiments of the present invention, alcohol is methanol which is inexpensive and easily available, alkali is potassium hydroxide because it contains elements useful for plant growth, and Yamato ABC is used as a treatment target. The expiration date of the powder fire extinguisher (hereinafter referred to as waste powder fire extinguisher) was used. Dissolve 2 g of potassium hydroxide in 1,000 ml of industrial methanol (99.9%) to obtain a treating agent. 10 kg of waste powder fire extinguishing agent was put into a thick plastic bag, and the treated chemical was poured and sealed, then placed in an 18 l can, covered with a lid, and left for 24 hours. When the product after the treatment was taken out and dissolved in water, the waste powder extinguishing agent, which was not completely soluble in water before the treatment, was easily dissolved in water to form a pink aqueous solution.
[0007] Powdered fire extinguishers that have been silicone-treated to impart water repellency and improve fluidity are difficult to handle because they fly up as dust even with a slight wind, making them unsuitable for processes such as stirring. Since the method of the present invention simply pours into the object to be treated and waits for the reaction with high alcohol permeability, the operation is extremely easy and no dust is generated.
Further, since the solubility of methanol in water is 100%, if the reaction time is not required to be short, water may be added to the treatment agent methanol to reduce the cost.
[0009]
According to the present invention, corn is cultivated, and a common fertilizer (a chemical fertilizer containing 15.0% of ammoniacal nitrogen, 15.0% of soluble phosphoric acid, and 10.0% of soluble potassium) is used. Three types of ridges were prepared, one using the obtained waste powder after the fire extinguishing agent treatment as a fertilizer and one not applying fertilizer, and comparing the effects. Although the fertilizer was not fertilized, the growth was poor, but the growth and fruiting of the regenerated fertilizer of the present invention were not inferior to those of the conventional fertilizer.
