産業上の利用分野
本発明は、ポリウレタン樹脂とニトラミン系爆薬を主剤
とする可塑性爆薬（以下ＰＢＸという）に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a plastic explosive (hereinafter referred to as PBX) whose main ingredients are a polyurethane resin and a nitramine explosive.
従来技術
ニトラミン系爆薬は高性能で低感度のため従来のトリニ
トロトルエン（以下ＴＮＴという）系爆薬に置き変わり
つ−あるが、融点が高く、ＴＮＴのように弾体に溶融充
填することができない。ＴＮＴと融合し、溶融充填する
ことは可能であるが、ＴＮＴの配合比を多くする必要が
あり、爆薬の威力が低下する。また被弾により爆発する
という欠点もある。Prior Art Nitramine-based explosives are replacing conventional trinitrotoluene (hereinafter referred to as TNT)-based explosives because of their high performance and low sensitivity, but they have a high melting point and cannot be melted and filled into bullets like TNT. Although it is possible to fuse with TNT and melt-fill it, it is necessary to increase the blending ratio of TNT, which reduces the power of the explosive. It also has the disadvantage of exploding when hit by a bullet.
弾体への爆薬の充填に際しては、気泡がないように充填
することが発射時仁高加速度を受ける砲弾ではとくに必
要であり、その方法としては溶融充填のほかに爆薬粉末

者の場合、爆発威力を増大させるためには爆薬成分の配
合比を多くすることが望まれるが、爆薬成分の配合比を
多くすると、可塑性が失われて粉状となる。When filling explosives into a shell, it is especially necessary to fill the shell without air bubbles, especially for shells that are subject to high acceleration during firing. There is a way to fill it as a PBX. In the latter case, it is desirable to increase the blending ratio of explosive components in order to increase the explosive power, but if the blending ratio of explosive components is increased, plasticity is lost and the product becomes powdery.
