【産業上の利用分野】
本発明は、着火薬およびその製造方法に関するものであり、詳しくは、特に、病害虫駆除剤の燻煙化における燃焼剤の着火薬として好適な着火薬およびその製造方法に関するものである。
【0002】
従来より、燃焼剤にて病害虫駆除剤を燻煙化することにより、温室やビニルハウス等に生息する病害虫を駆除する方法が知られている。例えば、本出願人によって提案された特開平2−212403号公報には、病害虫駆除剤の煙化方法およびその装置が提案されている。そして、上記の燃焼剤としては、例えば、過塩素酸塩、塩素酸塩、硝酸塩、亜硝酸塩、ニトロ化合物、過酸化物の一種または二種以上とこれに還元剤として多糖類を含む糖類を含有する混合物が使用される。
【0003】
【従来の技術】
ところで、病害虫駆除剤の燻煙化は、着火薬によって発生する熱で燃焼剤を発煙させることによって行われるため、着火薬は極めて重要であるにも拘わらず、未だ、その十分な検討は行われていない状況にある。例えば、上記の公開公報には、マッチ薬と擦り板との組み合わせから成る着火手段が開示されているが、マッチ薬の場合、主にその着火で出る炎によって燻煙剤に着火させるために熱ロスが大きく、しかも、固体燃焼の状態(燠の状態)で存在することが殆どないために燃焼剤の着火を確実に行うことが出来ない等の問題がある。
【0004】
【発明が解決しようとする課題】
本発明は、上記実情に鑑みなされたものであり、その目的は、炎の発生が殆どなく、燠の状態で存在する時間が長く、着火性に優れ、破損し難く、しかも、効率的かつ安全に製造することが出来、特に、病害虫駆除剤の燻煙化における燃焼剤の着火薬として好適な着火薬およびその製造方法を提供することにある。また、本発明の他の目的は、着火薬の安全な製造方法を提供することにある。
【0005】
【課題を解決するための手段】
すなわち、本発明の第1の要旨は、水に不溶ないしは難溶性の酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤をニトロセルロースによって無機繊維に担持して成ることを特徴とする着火薬に存し、第2の要旨は、水に不溶ないしは難溶性の酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤、ニトロセルロース、水溶性有機溶剤を混合して泥状混合液を調製し、当該泥状混合液に無機繊維マットを浸漬させて無機繊維マットに泥状混合液を担持させ、泥状混合液を担持した無機繊維マットを水中に浸漬し、水溶性有機溶剤を溶解除去することにより泥状混合液を固化して燃焼性粉剤およびニトロセルロースを無機繊維に担持させ、次いで、無機繊維マットをその乾燥前に所定の寸法に切断することを特徴とする着火薬の製造方法に存する。
【0006】
以下、本発明を詳細に説明する。
先ず、本発明の着火薬について説明する。本発明において、酸化剤、還元剤および燃焼調製剤としては、例えば、花火の材料成分として使用されている各種の酸化剤、還元剤および燃焼調製剤の中から水に不溶ないしは難溶性のものを適宜選択して使用することが出来る。例えば、酸化剤としては四三酸化鉛、還元剤としては珪素鉄、燃焼調製剤としては油煙が好適に使用されるが、これらの例に限定されるものではない。例えば、酸化剤としては、過酸化カルシウム、過酸化マンガン、酸化亜鉛、酸化バリウム、過酸化バリウム、酸化鉛、酸化鉄、酸化クロム等、還元剤としては、珪素、亜鉛、アルミニウム等、燃焼調製剤としては、松炭、麻炭、桐炭などを使用することも出来る。

【0008】
本発明の着火薬は、酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤をニトロセルロースによって無機繊維に担持してものである。ニトロセルロースは主としてバインダーとして作用し、また、無機繊維はその絡み合いによって比較的ポーラスなマトリックスを形成するための担体として作用する。
【0009】
酸化剤、還元剤および燃焼調製剤の各割合は、主に酸化剤と還元剤の組み合わせてによって酸素平衡が大きく異なるために一概には決定できず、上記の組み合わせごとに適宜選択される。四三酸化鉛と珪素鉄と油煙の組み合わせの場合、通常、100:10〜100:1〜20(重量比)、好ましくは、100:20〜60:5〜10(重量比)の範囲とされる。一方、燃焼性粉剤とニトロセルロースとの割合は、通常、100:5〜30(重量比)、好ましくは、100:5〜20(重量比)の範囲とされる。無機繊維は、着火薬の後述する製造方法に従い、マットとして使用される。この場合、マット1m2 当たりの前記成分の担持量は、通常1〜15Kg、好ましくは3〜10Kgの範囲とされる。
【0010】
次に、本発明の着火薬の製造方法について説明する。本発明の製造方法は、水に不溶ないしは難溶性の酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤、ニトロセルロース、水溶性有機溶剤を混合して泥状混合液を調製し、当該泥状混合液に無機繊維マットを浸漬させて無機繊維マットに泥状混合液を担持させ、泥状混合液を担持した無機繊維マットを水中に浸漬し、水溶性有機溶剤を溶解除去することにより泥状混合液を固化して燃焼性粉剤およびニトロセルロースを無機繊維に担持させ、次いで、無機繊維マットをその乾燥前に所定の寸法に切断することを特徴とする。斯かる製造方法によれば、燃焼性粉剤およびニトロセルロースを含む泥状混合液の固化を水中で行い、また、燃焼性粉剤およびニトロセルロースを担持した無機繊維マットの切断をその乾燥前に行うため、燃焼や爆発など危険を回避して安全に着火薬を製造することが出来る。
【0011】
先ず、第1工程において、酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤、ニトロセルロース、水溶性有機溶剤を混合して泥状混合液を調製する。水溶性有機溶剤としては、メタノール等の低級アルコール、アセトン等の低級ケトンが好適に使用される。水溶性有機溶剤の使用割合は、特に制限されないが、通常、燃焼性粉剤とニトロセルロースの合計量に対し、0.3〜1.0重量倍の範囲から選択される。
【0012】
上記の泥状混合液の調製において、各成分の添加順序は特に制限されないが、水溶性有機溶剤とニトロセルロースの溶液に燃焼調製剤を添加して混合し、得られた混合液に酸化剤と還元剤との混合物を添加して混合するのがよい。
【0013】
次に、第2工程において、泥状混合液に無機繊維マットを浸漬させて無機繊維マットに泥状混合液を担持させる。浸漬処理は、泥状混合液を収容した容器内に無機繊維マットを浸漬し、容器内で無機繊維マットを適宜動かし、無機繊維マットに泥状混合液を十分担持させる。無機繊維マットとしては、自由厚さが1〜5mm程度のものが好適に使用される。
【0014】
次に、第3工程において、泥状混合液を担持した無機繊維マットを水中に浸漬し、水溶性有機溶剤を溶解除去する。これにより、泥状混合液は直ちに固化し燃焼性粉剤およびニトロセルロースは無機繊維マットに担持される。また、水溶性有機溶剤の溶解除去により、無機繊維マットに担持される燃焼性粉剤およびニトロセルロースのマトリックスはポーラス状態となる。上記の水中浸漬は、10〜20分の短時間で十分であり、また、泥状混合液の固化を促進するため、必要に応じ、流水条件下に行ってもよい。
【0015】
次に、第4工程において、無機繊維マットをその乾燥前に所定の寸法に切断する。通常、幅は1〜20mmとされ、長さは使用態様により適宜決定される。無機繊維マットの切断は、乾燥前の含水状態で行われるため、発火や燃焼などの恐れがなく安全に行うことが出来る。切断後の乾燥は、通常、40〜80℃の温度で1〜3時間行えば十分である。
【0016】
本発明の着火薬は、無機繊維マットを使用した上記の製造方法の他、無機繊維チョップスランドを使用し、酸化剤、還元剤および燃焼調製剤より成る燃焼性粉剤、ニトロセルロース、水溶性有機溶剤、無機繊維チョップスランドの泥状混合物をノズル口から水中に押し出す方法によって製造することも出来る。斯かる製造方法によれば、ノズル口の断面形状に従い、着火薬の断面形状を例えば星型とすることが出来る。斯かる断面形状の着火薬は、その鋭角部を利用し、着火薬に対する着火を一層容易に行うことが出来る。

[0002]
BACKGROUND ART Conventionally, there has been known a method of exterminating pests that inhabit greenhouses, greenhouses, and the like by smoking a pesticide with a burning agent. For example, Japanese Unexamined Patent Publication No. 2-212403 proposed by the present applicant proposes a method and an apparatus for smoking a pesticide. And, as the above-mentioned burning agent, for example, one or more of perchlorate, chlorate, nitrate, nitrite, nitro compound, peroxide and a saccharide containing a polysaccharide as a reducing agent are contained. A mixture is used.
[0003]
[Prior art]
By the way, since smoking of a pesticide is carried out by fuming a burning agent with heat generated by the ignition agent, although the ignition agent is extremely important, it is still not sufficiently studied. Not in a situation. For example, the above-mentioned publication discloses an ignition means composed of a combination of a match medicine and a rubbing plate. In the case of a match medicine, however, heat is mainly applied to ignite the smoking agent by the flame generated by the ignition. There is a problem that the loss is large and the combustion agent cannot be reliably ignited because it hardly exists in the state of solid combustion (emulsion state).
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to generate almost no flame, to stay in the state of embroidery for a long time, to have excellent ignitability, to be hard to break, and to be efficient and safe. In particular, it is an object of the present invention to provide an igniting agent suitable as an igniting agent for a burning agent in smoking of a pesticide and a method for producing the igniting agent. It is another object of the present invention to provide a method for safely producing an igniting agent.
[0005]
[Means for Solving the Problems]
That is, a first gist of the present invention is an igniting agent characterized in that a flammable powder comprising an oxidizing agent, a reducing agent and a combustion controlling agent which are insoluble or hardly soluble in water is supported on inorganic fibers by nitrocellulose. The second gist is that a muddy liquid mixture is prepared by mixing a flammable powder comprising an oxidizing agent, a reducing agent and a combustion regulator, which are insoluble or hardly soluble in water, nitrocellulose, and a water-soluble organic solvent. Then, the inorganic fiber mat is immersed in the mud-like mixed liquid to carry the mud-like mixed liquid on the inorganic fiber mat, and the inorganic fiber mat carrying the mud-like mixed liquid is immersed in water to dissolve and remove the water-soluble organic solvent. A method for producing an igniting powder characterized by solidifying a muddy mixture to support a combustible powder and nitrocellulose on inorganic fibers, and then cutting the inorganic fiber mat into predetermined dimensions before drying. Existence That.
[0006]
Hereinafter, the present invention will be described in detail.
First, the igniting agent of the present invention will be described. In the present invention, examples of the oxidizing agent, reducing agent and combustion regulator include, among various oxidizing agents, reducing agents and combustion regulators used as material components of fireworks, those insoluble or hardly soluble in water. It can be appropriately selected and used. For example, lead tetroxide is preferably used as the oxidizing agent, silicon iron is used as the reducing agent, and oily fume is used as the combustion regulator. However, the present invention is not limited to these examples. For example, as an oxidizing agent, calcium peroxide, manganese peroxide, zinc oxide, barium oxide, barium peroxide, lead oxide, iron oxide, chromium oxide, etc., as a reducing agent, silicon, zinc, aluminum, etc., a combustion control agent For example, pine charcoal, hemp charcoal, and paulownia charcoal can be used.
[0007]
In the present invention, the nitrocellulose is not particularly limited, but those having a low nitrogen content are preferably used. Glass fibers, asbestos fibers, alumina fibers and the like are used as the inorganic fibers.
[0008]
In the igniting agent of the present invention, a combustible powder comprising an oxidizing agent, a reducing agent and a combustion controlling agent is supported on inorganic fibers by nitrocellulose. Nitrocellulose mainly acts as a binder, and the inorganic fibers act as a carrier for forming a relatively porous matrix by entanglement.
[0009]
The proportions of the oxidizing agent, the reducing agent, and the combustion control agent cannot be unconditionally determined because the oxygen balance largely differs depending on the combination of the oxidizing agent and the reducing agent, and is appropriately selected for each of the above combinations. In the case of a combination of lead tetroxide, silicon iron and oil fumes, it is usually in the range of 100: 10 to 100: 1 to 20 (weight ratio), preferably 100: 20 to 60: 5 to 10 (weight ratio). You. On the other hand, the ratio between the combustible powder and the nitrocellulose is usually in the range of 100: 5 to 30 (weight ratio), preferably 100: 5 to 20 (weight ratio). The inorganic fibers are used as a mat in accordance with a method for producing an igniting agent described later. In this case, the amount of the component carried per m 2 of the mat is usually in the range of 1 to 15 kg, preferably 3 to 10 kg.
[0010]
Next, a method for producing the igniting agent of the present invention will be described. In the production method of the present invention, a muddy liquid mixture is prepared by mixing a flammable powder comprising an oxidizing agent which is insoluble or hardly soluble in water, a reducing agent, and a combustion modifier, nitrocellulose, and a water-soluble organic solvent. The inorganic fiber mat is immersed in the slurry mixture, the mud mixture is supported on the inorganic fiber mat, the inorganic fiber mat supporting the slurry mixture is immersed in water, and the water-soluble organic solvent is dissolved and removed. The solid mixture is solidified to support the combustible powder and nitrocellulose on the inorganic fibers, and then the inorganic fiber mat is cut to a predetermined size before drying. According to such a production method, the muddy liquid mixture containing the combustible powder and nitrocellulose is solidified in water, and the cutting of the inorganic fiber mat supporting the combustible powder and nitrocellulose is performed before drying. Thus, it is possible to safely manufacture an ignition charge while avoiding dangers such as combustion and explosion.
[0011]
First, in a first step, a combustible powder comprising an oxidizing agent, a reducing agent and a combustion controlling agent, nitrocellulose, and a water-soluble organic solvent are mixed to prepare a muddy liquid mixture. As the water-soluble organic solvent, lower alcohols such as methanol and lower ketones such as acetone are preferably used. The usage ratio of the water-soluble organic solvent is not particularly limited, but is usually selected from the range of 0.3 to 1.0 weight times the total amount of the combustible powder and nitrocellulose.
[0012]
In the preparation of the above-mentioned muddy mixture, the order of addition of each component is not particularly limited. The mixture with the reducing agent is preferably added and mixed.
[0013]
Next, in the second step, the inorganic fiber mat is immersed in the muddy mixed liquid to carry the muddy mixed liquid on the inorganic fiber mat. In the immersion treatment, the inorganic fiber mat is immersed in a container containing the muddy liquid mixture, and the inorganic fiber mat is appropriately moved in the container to sufficiently support the muddy liquid mixture on the inorganic fiber mat. As the inorganic fiber mat, one having a free thickness of about 1 to 5 mm is suitably used.
[0014]
Next, in a third step, the inorganic fiber mat supporting the muddy mixture is immersed in water to dissolve and remove the water-soluble organic solvent. As a result, the muddy mixture is immediately solidified, and the combustible powder and nitrocellulose are supported on the inorganic fiber mat. Further, by dissolving and removing the water-soluble organic solvent, the combustible powder and the matrix of nitrocellulose carried on the inorganic fiber mat become porous. The above-mentioned immersion in water is sufficient for a short time of 10 to 20 minutes. In order to promote the solidification of the muddy mixture, the immersion in water may be performed under flowing water if necessary.
[0015]
Next, in a fourth step, the inorganic fiber mat is cut into predetermined dimensions before drying. Usually, the width is 1 to 20 mm, and the length is appropriately determined depending on the use mode. Since the cutting of the inorganic fiber mat is performed in a water-containing state before drying, it can be safely performed without fear of ignition or combustion. Drying after cutting is usually sufficient at a temperature of 40 to 80 ° C. for 1 to 3 hours.
[0016]
The igniting powder of the present invention is, in addition to the above-mentioned production method using an inorganic fiber mat, using an inorganic fiber chop land, a flammable powder comprising an oxidizing agent, a reducing agent and a combustion regulator, nitrocellulose, a water-soluble organic solvent. Alternatively, it can be produced by a method in which a muddy mixture of inorganic fiber chopsland is extruded into water from a nozzle opening. According to such a manufacturing method, the cross-sectional shape of the ignition agent can be, for example, a star shape according to the cross-sectional shape of the nozzle port. The igniting agent having such a cross-sectional shape makes it possible to more easily ignite the igniting agent by utilizing the acute angle portion.
[0017]

A glass fiber mat having a thickness of 3 mm was immersed in the mud-like liquid mixture to carry the mud-like liquid mixture on the glass fiber mat.
[0019]
Next, the glass fiber mat supporting the muddy mixture was immersed in water for 15 minutes, and methanol was dissolved and removed to solidify the muddy mixture. Then, immediately, the glass fiber mat was cut into a size of 3 mm in thickness and 5 mm in width. The length was 100 mm. And it dried at the temperature of 60 degreeC for 2 hours, and obtained the ignition charge.
