Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、打上げ花火に用いられる玉皮の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a cork used for launch fireworks.
［従来の技術］ 打上げ花火は第２図に示すように、玉皮1,1を合せて
球体とし、内部に割薬２を充填してあって、この割薬２
を親導３によって爆発させ、玉皮１を破裂させるととも
に、図示していないが、国旗やパラシュート等の内容物
の放出あるいは星等への着火や初速付与を行っている。[Prior Art] As shown in FIG. 2, a launch fireworks is made up of a sphere formed by combining the corks 1 and 1 and filled with a preservative 2 therein.
Is exploded by the leader 3 to rupture the cork 1 and, although not shown, discharges contents such as a national flag and a parachute, ignites a star or the like, and gives initial velocity.
玉皮１としては、新聞紙を糊で貼り合わせたものと、
ボール紙を圧搾して半球形体に仕上げたものが知られて
いる。新聞紙で作った玉皮の強度は抗張力として縦70〜
80kg/cm2、横で35kg/cm2程度である。ボール紙製の玉皮
は新聞紙製のものより劣る強度である。As the cork 1, newspaper paper is glued with glue,
It is known that cardboard is pressed into a hemispherical shape. The strength of the cork made of newspaper is 70 ~
80kg / cm 2, is a lateral in the 35kg / cm 2 about. Corrugated cardboard has less strength than newsprint.
［発明が解決しようとする課題］ 従来の花火においては、打上げ後、爆発して、分散さ
れた未燃および燃えている玉皮が地上に落下してきて、
人や構築物等にあたったりして、地上に散乱して、翌日
それらを回収する必要があった。又、火災の原因になる
恐れもあった。[Problems to be Solved by the Invention] In conventional fireworks, after launch, they explode and dispersed unburned and burning corks fall to the ground,
It was necessary to collect them the next day, scattered on the ground by hitting people or structures. There was also a risk of fire.
本発明は未燃および燃えている状態で地上に落下する
ことのない打上げ花火用玉皮を提供しようとするもので
ある。An object of the present invention is to provide a launch firework skin that does not fall to the ground in an unburned or burned state.
［課題を解決するための手段］ 本発明は、窒素量が12.0〜13.15％のニトロセルロー
スとクラフトパルプを主成分とする焼尽製半球形体を成
形し、その外面に不燃剤を塗布してなる打上げ花火用玉
皮である。[Means for Solving the Problems] The present invention relates to a fireworks display formed by forming an exhausted hemispherical body mainly composed of nitrocellulose having a nitrogen content of 12.0 to 13.15% and kraft pulp, and applying a flame retardant to the outer surface thereof. It is a skin for use.
上記半球形体の望ましい材料組成は、ニトロセルロー
ス40〜70％、クラフトパルプ10〜30％、安定剤１〜３
％、バインダー10〜30％である。Desirable material compositions of the hemispherical bodies are nitrocellulose 40-70%, kraft pulp 10-30%, stabilizers 1-3.
%, Binder 10-30%.
本発明では無煙火薬の基剤であるニトロセルロースを
主成分として用いているので、燃焼力が強く、又、煙の
発生もない。クラフトパルプは玉皮に強度を付与し成形
性を保つ。In the present invention, since nitrocellulose, which is the base of smokeless powder, is used as a main component, it has a strong combustion power and does not generate smoke. Kraft pulp imparts strength to the bark and maintains its formability.
バインダーとしてはスチレン−ブタジエン樹脂が好適
に用いられる。又、ニトロセルロースは自然に分解して
いくことがあるので、安定剤を混入する。安定剤として
エチルセントラリットなどが用いられる。Styrene-butadiene resin is preferably used as the binder. In addition, since nitrocellulose may decompose spontaneously, a stabilizer is added. Ethyl centralite or the like is used as a stabilizer.
これらの配合割合は前述の範囲がそれぞれの機能を十
分に果す上で好適である。These mixing ratios are suitable for the above ranges to sufficiently fulfill their functions.
焼尽性半球形体の外面に塗布する不燃剤としては、例
えばウレタン樹脂、アクリル樹脂等を用いているので吸
湿が防止でき、かつ不慮の着火による災害の発生が防止
できる。As a non-combustible agent applied to the outer surface of the burnable hemispherical body, for example, a urethane resin, an acrylic resin, or the like is used, so that moisture absorption can be prevented and occurrence of a disaster due to accidental ignition can be prevented.
［実施例］ 次に実施例を図面によって説明する。Example Next, an example will be described with reference to the drawings.
ニトロセルロース（窒素量13.15％） 58％ クラフトパルプ 20％ バインダー 20％ 安定剤 ２％ からなる組成物をもって、第１図に示す焼尽性半球形体
４をつくり、その外側に不燃剤としてウレタン樹脂５を
塗布した。かかる焼尽性半球形体４を２つ合せて球体の
玉皮とし、内部に適当数の星６、小割７並びに割薬８を
配置し、クラフト紙９によって焼尽性半球形体4,4同士
の接合部分を結合して、打上げ花火５号玉を作成した。
なお、３は親導である。Nitrocellulose (nitrogen content 13.15%) 58% Kraft pulp 20% Binder 20% Stabilizer 2% is used to make a burnable hemispherical body 4 shown in FIG. 1, and a urethane resin 5 is used as a non-combustible agent on the outside. Applied. Two such burnable hemispheres 4 are combined to form a sphere skin, and an appropriate number of stars 6, small splitters 7 and splitting agents 8 are disposed inside, and the burnable hemispheres 4 and 4 are joined together by kraft paper 9. The fireworks No. 5 ball was launched by combining the parts.
In addition, 3 is a leader.
この花火玉を通常の方法で打上げた結果、焼尽性半球
形体よりつくった玉皮は空中で分断されながら燃え尽き
て地上に落下してこなかった。As a result of launching this fireworks ball in the usual manner, the bark made of burnable hemispheres did not fall to the ground and burned out while being divided in the air.
［発明の効果］ 本発明の玉皮を使用して作成した花火玉は、打上げ時
は外側に不燃剤を塗布しているので、燃えることがなく
打上げられ、空中で着火された割薬の炎で、本発明の玉
皮に着火し、空中で燃え尽き、地上に落下することがな
い。[Effect of the Invention] A fireworks ball made by using the skin of the present invention is fired without burning because a non-combustible agent is applied to the outside at the time of launch, and is ignited in the air. Thus, the bark of the present invention is ignited, burns out in the air, and does not fall to the ground.
本発明品は工業的に連続製造可能であり、新聞紙の貼
り合わせの様に手作りでないので、常に一定の強度の打
上げ花火用玉皮が量産できる。Since the product of the present invention can be continuously manufactured industrially and is not handmade as in the case of pasting newspaper, mass production of fireworks skins having a certain strength can always be carried out.
