実施例２〜１４に係る無鉛爆粉は、実施例１の無鉛爆粉の組成について、種々変化させて構成したものである。また、これらの組成物の総重量に対し、外割として添加される粘結剤としてのゴム液は、５又は１０重量％添加されている。なお、実施例２〜１４における無鉛爆粉の作製方法は、実施例１と同様である。実施例２〜１４においても、外割０〜１０重量％のタルク若しくは二酸化ケイ素、又はタルク及び二酸化ケイ素の混合物を添加することが望ましい。
(Examples 2 to 14)
The lead-free powders according to Examples 2 to 14 are configured by variously changing the composition of the lead-free powder according to Example 1. In addition, 5 or 10% by weight of a rubber liquid as a binder added as an outer split is added to the total weight of these compositions. In addition, the production method of the lead-free explosion in Examples 2-14 is the same as that of Example 1. Also in Examples 2 to 14, it is desirable to add 0 to 10% by weight of talc or silicon dioxide or a mixture of talc and silicon dioxide.
ここで、上記実施例１〜１４につき、発火感度、着火性、物理的な不具合事象等の各種評価の試験結果を下記［表１］に示す。なお、表中［―］で示されるのは、非添加を示し、［○］は、定性的な評価により、要求を十分に満足するという意味を表している。 Here, with respect to Examples 1 to 14, test results of various evaluations such as ignition sensitivity, ignitability, and physical failure events are shown in [Table 1] below. In the table, [-] indicates no addition, and [◯] indicates that the requirement is sufficiently satisfied by qualitative evaluation.
なお、比較例として、比較例１〜１４のトリシネートを爆粉とする***について、実施例１〜１４と同様の評価試験を行った試験結果を下記［表２］に示す。なお、表中［―］で示されるのは、非添加を示し、［○］は、定性的な評価により、要求を十分に満足するという意味を表している。 In addition, as a comparative example, the following [Table 2] shows the test result which performed the evaluation test similar to Examples 1-14 about the detonator which made the tricinate of Comparative Examples 1-14 explosive powder. In the table, [-] indicates no addition, and [◯] indicates that the requirement is sufficiently satisfied by qualitative evaluation.
そして、［表１］、［表２］に示す通り、実施例１〜１４のいずれについても、鉛を含まない爆粉を用いているにも関わらず、発火感度、着火性、物理的な不具合事象等の要求される性能を十分に満たして、小銃・機関銃、拳銃等の火器に使用される実包や空包などの***を構成する無鉛爆粉となり得ることが分かった。
なお、［表２］に示す通り、比較例１〜１４についてもその諸性能については問題はない。しかしながら、トリシネートは、成分中に鉛を含むため好ましくなく、その理由については、既に上述している。
And as shown in [Table 1] and [Table 2], in any of Examples 1 to 14, the ignition sensitivity, the ignitability, and the physical defects were used in spite of the use of explosives not containing lead. It has been found that it can be a lead-free explosive that constitutes a detonator such as an actual package or an empty package used in firearms such as rifles, machine guns, and handguns, sufficiently satisfying the required performance such as events.
In addition, as shown in [Table 2], there are no problems with respect to the performances of Comparative Examples 1 to 14. However, tricinate is not preferred because it contains lead in the component, and the reason has already been described above.
ここで、本発明に係る無鉛爆粉の組成につき、ジアゾジニトロフェノールは、２０重量％よりも少ないと発火感度が低く、弾丸を飛翔させるための発射薬の着火性が低下するため好ましくない。一方、４０重量％よりも多いと発火威力が大きすぎるため、***突破や出管などの物理的不具合事象が発生するので好ましくない。
テトラセンは、２０重量％よりも多いと発火感度は高くなるが、ジアゾジニトロフェノールの割合の低下により発射薬への着火性が低下するため好ましくない。
硝酸バリウムは、２０重量％よりも少ないと発火感度が低く、弾丸を飛翔させるための発射薬の着火性が低下するため好ましくない。一方、４０重量％よりも多いと発射薬への着火性が向上するが、ジアゾジニトロフェノールの割合の減少により発火感度が低下するため好ましくない。
ケイ化カルシウムは、５重量％より少ないと弾丸を飛翔させるための発射薬の着火性が低下するため好ましくない。一方、３０重量％よりも多いと発射薬への着火性が向上するが、ジアゾジニトロフェノールの割合が低下して発火感度が低下するため好ましくない。
Here, regarding the composition of the lead-free explosive powder according to the present invention, if diazodinitrophenol is less than 20% by weight, the ignition sensitivity is low, and the ignitability of the propellant for flying bullets is not preferable. On the other hand, if the amount is more than 40% by weight, the ignition power is too large, and physical trouble events such as detonator breakout and outlet tube occur, which is not preferable.
When tetracene is more than 20% by weight, the ignition sensitivity becomes high, but the ignitability of the propellant is lowered due to a decrease in the ratio of diazodinitrophenol, which is not preferable.
If the barium nitrate is less than 20% by weight, the ignition sensitivity is low, and the ignitability of the propellant for flying the bullet is lowered, which is not preferable. On the other hand, if the amount is more than 40% by weight, the ignitability to the propellant is improved, but the ignition sensitivity is lowered due to a decrease in the proportion of diazodinitrophenol, which is not preferable.
If the calcium silicide is less than 5% by weight, the ignitability of the propellant for flying the bullet is lowered, which is not preferable. On the other hand, if the amount is more than 30% by weight, the ignitability to the propellant is improved, but the ratio of diazodinitrophenol is lowered and the ignition sensitivity is lowered, which is not preferable.
また、三硫化アンチモンは、２０重量％よりも多いと発火感度は高くなるが、ジアゾジニトロフェノールの割合の低下により発射薬への着火性が低下するため好ましくない。

粘結剤（ゴム液）は、０．５重量％より少ないと製造性に支障がでるため好ましくない。一方、１０重量％よりも多いと発火感度が低下するため好ましくない。
タルク若しくは二酸化珪素、又は、これらの混合物は、１０重量％よりも多いと発火感度が低下するため好ましくない。
Further, when antimony trisulfide is more than 20% by weight, the ignition sensitivity becomes high, but it is not preferable because the ignitability to the propellant is lowered due to a decrease in the ratio of diazodinitrophenol.
If the glass powder is more than 20% by weight, the ignition sensitivity becomes high, but the ignitability of the propellant is lowered due to a decrease in the ratio of diazodinitrophenol.
If the amount of the binder (rubber liquid) is less than 0.5% by weight, it is not preferable because the productivity is impaired. On the other hand, if it is more than 10% by weight, the ignition sensitivity is lowered, which is not preferable.
Talc, silicon dioxide, or a mixture thereof is not preferable if it exceeds 10% by weight because the ignition sensitivity is lowered.
そして、ジアゾジニトロフェノールを２０〜４０重量％、硝酸バリウムを２０〜４０重量％、ケイ化カルシウムが５〜３０重量％、三硫化アンチモンを重量１〜２０％、テトラセンを０〜２０重量％、ガラス粉を０〜２０重量％の範囲の組成とし、これらの合計を１００重量％に適宜調製するとともに、外割にて粘調剤を０．５〜１０重量％添加すれば、本発明に係る無鉛爆粉を得ることができる。 20 to 40% by weight of diazodinitrophenol, 20 to 40% by weight of barium nitrate, 5 to 30% by weight of calcium silicide, 1 to 20% by weight of antimony trisulfide, 0 to 20% by weight of tetracene, glass If the powder is made into a composition in the range of 0 to 20% by weight, and the total of these is adjusted to 100% by weight as appropriate, and the thickener is added in an external ratio of 0.5 to 10% by weight, the lead-free explosion according to the present invention Powder can be obtained.
