Definitions
- the present invention relates to new priming charges with central or annular percussion, as well as their manufacturing process.
- priming filler compositions based on mercury fulminate are practically no longer used, essentially due to their high toxicity and their lack of thermal stability. They were first replaced by compositions containing compounds of lead, antimony and barium. These latter compounds, during the operation of the primer, give rise to the emission of residues containing these elements which are released into the atmosphere. They thus cause serious pollution of the premises, shooting ranges, often confined in which the cartridges are fired in great numbers.
- EP-A-0 012 081 describes, for example, compositions using diazodinitrophenol as an energy explosive.
- these compositions have the drawback of containing, as an oxidizing agent, zinc peroxide, which is difficult to obtain in a state of sufficient purity, as well as powdered titanium as a reducing agent.
- the latter has the disadvantage of a high price, and a certain toxicity.
- the object of the present invention is precisely to develop new compositions which can be used in primers with central or annular percussion, which do not exhibit any toxicity.
- the percussion initiation charges, free from toxic metal, in accordance with the present invention are of the type comprising at least one primary explosive, an oxidizing agent, a reducing agent and an inert abrasive powder. They are essentially characterized in that said oxidizing agent contains copper oxide.
- the percussion initiation charges advantageously correspond to the following weight composition: 10 to 40% diazodinitrophenol; 10 to 60% of a shock-sensitive booster explosive; 10 to 40% cupric oxide; 5 to 20% of a pulverulent reducing agent; 5 to 25% of an inert abrasive powder, and 0 to 5% of a binder.
- the extra explosive sensitive to shock can be constituted by tetrazene.
- the percussion ignition charges according to the invention then respond to a weight composition of the following type: 20 to 40% diazodinitrophenol; 10 to 30% tetrazene; 20 to 40% cupric oxide; 5 to 20% aluminum powder; 5 to 20% glass powder; 0 to 5% of binder.
- the extra explosive sensitive to shock consists of a dinitrobenzofuroxane salt, in particular the potassium salt.
- the percussion initiation charges according to the invention correspond to the following weight composition: 5 to 25% diazodinitrophenol; 35 to 55% of potassium dinitrobenzofuroxane; 10 to 30% cupric oxide; 5 to 20% iron powder; 5 to 20% glass powder, and 0 to 5% of binder.
- This particular type of percussion ignition charge remains stable up to temperatures at least 120 ° C.
- the percussion initiation charges may also contain an additional oxidizing agent, chosen from ferric oxide, metallic salycilates, ascorbic acid, mineral or organic peroxides as well as mixtures of these compounds.
- the pulverulent reducing agent will advantageously be chosen from aluminum, iron, zinc, magnesium and also mixtures of these metals.
- the inert abrasive powder is advantageously constituted by glass powder.
- the reducing agent and / or the inert abrasive powder may be based on calcium silicide.
- the latter compound alone can fulfill both the functions of reducing agent and abrasive agent.
- the present invention also relates to a method for manufacturing percussion ignition charges as defined above.
- this process is characterized in that the following successive steps are carried out: * the copper oxide, the reducing agent (s) and the abrasive powder are dry mixed; * the diazodinitrophenol and the additional explosive are added to this inert mixture, and * the mixture thus obtained is homogenized.
- a binder solution is added to the inert mixture, for example in the form of an aqueous solution of gum arabic.
- the non-explosive ingredients are weighed: cupric oxide, aluminum and glass powder and are introduced into a rotary mixer where they are stirred until homogeneous. They are then transferred to a planetary mixer for wet compositions, the necessary amount of water is added, then the diazodinitrophenol and tetrazene previously weighed are poured in and finally an aqueous solution of gum arabic acting as a binder.
- the various pulverulent constituents are generally used with an average particle size of less than approximately 250 ⁇ m. We mix for the necessary time.
- the composition is then ready for use, it contains the following percentages by dry weight: Diazodinitrophenol 29.8% Tetrazene 19.8% Cupric oxide 29.8% Aluminum powder 9.8% Glass powder 9.8% Gum arabic 1.0%
- This composition is then distributed by spreading according to the conventional method in primer cells with a diameter of 4.45 mm so as to obtain charges of 18 ⁇ 2 mg per primer.
- Using a flat punch place a paper disc, then dry the primers and compresses according to the conventional method with a pressing force of 150 daN on each primer. After varnishing, the anvil is put in place and the drying is finished.
- These primers are then tested in sensitivity on a firing assembly for primers: 0 ⁇ 2 mm round point striker 55 g ball Fall height 220 mm Result: out of 50 priming charges tested, all work
- Primers are also mounted on .38sp caliber cases which are tested on a drop sheep with the same ball.
- the average operating height H obtained is 140 mm, with an estimated standard deviation S of 22 mm, which gives an H + 5S of 250 mm and an H-2S of 96 mm.
- .38sp cartridges are made with the above primers, 430 mg of BA9 powder and truncated semi-armored bullets. They are then drawn with a Smith and Wesson mle 58G pistol. They give an initial speed of 300 ⁇ 5 m / s, which is perfectly correct.
- a composition according to the second variant of the invention is prepared in the same manner as above, containing: Potassium dinitrobenzofuroxan 44.8% Diazodinitrophenol 14.8% Cupric oxide 19.8% Powdered iron 9.8% Glass powder 9.8% Gum arabic 1.0%
- This composition is distributed by spreading in cases for annular percussion of .22 or 6 mm or 9 mm caliber or other and distributed by compression or turbination or any other mechanical means, in the bead thereof. These cases are tested for their sensitivity to percussion: the fall of a 111.7 g ball on the striker from a height of 200 mm causes certain operation, which is considered satisfactory for this type of ammunition .

Abstract
Description
- La présente invention concerne de nouvelles charges d'amorçage à percussion centrale ou annulaire, ainsi que leur procédé de fabrication.
- Les charges d'amorçage destinées à assurer l'allumage des poudres propulsives dans les cartouches de tir et de guerre, à percussion annulaire ou centrale et généralement dans tous les dispositifs produisant une flamme à partir de l'action d'un percuteur, présentent actuellement l'inconvénient de renfermer des composés toxiques.
- De nos jours, les compositions de charges d'amorçage à base de fulminate de mercure ne sont pratiquement plus utilisées, essentiellement en raison de leur forte toxicité et de leur manque de stabilité thermique. Elles ont tout d'abord été remplacées par des compositions renfermant des composés du plomb, de l'antimoine et du baryum. Ces derniers composés, lors du fonctionnement de l'amorce, donnent lieu à l'émission de résidus contenant ces éléments qui sont libérés dans l'atmosphère. Ils occasionnent ainsi une grave pollution des locaux, stands de tir, souvent confinés dans lesquels les cartouches sont tirées en très grand nombre.
- Ce problème de toxicité a été soulevé depuis quelques années, et l'on a déjà tenté à plusieurs reprises de le résoudre.
- EP-A-0 012 081 décrit par exemple des compositions utilisant le diazodinitrophénol en tant qu'explosif énergétique. Ces compositions présentent cependant l'inconvénient de renfermer en tant qu'agent oxydant du peroxyde de zinc, difficile à obtenir à l'état de pureté suffisant, ainsi que du titane en poudre en tant qu'agent réducteur. Ce dernier présente l'inconvénient d'un prix élevé, et d'une certaine toxicité.
- Une autre composition a été décrite dans US-A-4 675 059 qui fait également appel au diazodinitrophénol en tant qu'explosif mais qui utilise le bioxyde de manganèse en tant qu'agent oxydant. Ce dernier présente une concentration maximale tolérable dans l'air de 5 mg/m³ et ne peut donc pas être considéré comme un produit non toxique.
- La présente invention a précisément eu pour but de mettre au point de nouvelles compositions utilisables dans les amorces à percussion centrale ou annulaire, qui ne présentent pas de toxicité.
- Les charges d'amorçage à percussion, exempte de métal toxique, conformes à la présente invention sont du type comprenant au moins un explosif primaire, un agent oxydant, un agent réducteur et une poudre abrasive inerte. Elles sont essentiellement caractérisées en ce que ledit agent oxydant contient de l'oxyde de cuivre.
- Conformément à la présente invention, les charges d'amorçage à percussion répondent avantageusement à la composition pondérale suivante :
10 à 40 % de diazodinitrophénol ;
10 à 60 % d'un explosif d'appoint sensible au choc ;
10 à 40 % d'oxyde cuivrique ;
5 à 20 % d'un agent réducteur pulvérulent ;
5 à 25 % d'une poudre abrasive inerte, et
0 à 5 % d'un liant. - Selon une première variante, l'explosif d'appoint sensible au choc peut être constitué par du tétrazène.
- Les charges d'amorçage à percussion selon l'invention répondent alors à une composition pondérale du type suivant :
20 à 40 % de diazodinitrophénol;
10 à 30 % de tétrazène;
20 à 40 % d'oxyde cuivrique;
5 à 20 % d'aluminium en poudre;
5 à 20 % de poudre de verre;
0 à 5 % de liant. - Selon une seconde variante de l'invention, l'explosif d'appoint sensible au choc est constitué par un sel de dinitrobenzofuroxanne, en particulier le sel de potassium.
- Dans pareil cas, les charges d'amorçage à percussion selon l'invention répondent à la composition pondérale suivante :
5 à 25 % de diazodinitrophénol;
35 à 55 % de dinitrobenzofuroxanne de potassium;
10 à 30 % d'oxyde cuivrique;
5 à 20 % de fer en poudre;
5 à 20 % de poudre de verre, et
0 à 5 % de liant. - Ce type particulier de charges d'amorçage à percussion reste stable jusqu'à des températures au moins égales à 120°C.
- Selon une autre caractéristique de l'invention, les charges d'amorçage à percussion peuvent en outre contenir un agent oxydant additionnel, choisi parmi l'oxyde ferrique, les salycilates métalliques, l'acide ascorbique, les peroxydes minéraux ou organiques ainsi que les mélanges de ces composés.
- Selon une autre caractéristique de l'invention, l'agent réducteur pulvérulent sera avantageusement choisi parmi l'aluminium, le fer, le zinc, le magnésium ainsi que les mélanges de ces métaux.
- Enfin, selon une autre caractéristique de l'invention, la poudre abrasive inerte est avantageusement constituée par de la poudre de verre.
- Dans un mode de réalisation particulier des charges d'amorçage à percussion selon l'invention, l'agent réducteur et/ou la poudre abrasive inerte peuvent être à base de siliciure de calcium. Ce dernier composé peut, à lui seul, remplir à la fois les fonctions d'agent réducteur et d'agent abrasif.
- La présente invention concerne également un procédé de fabrication des charges d'amorçage à percussion telles que définies précédemment. Selon l'invention ce procédé est caractérisé en ce que l'on réalise les étapes successives suivantes :
* on mélange à sec l'oxyde cuivrique, le ou les agent(s) réducteur(s) et la poudre abrasive ;
* on ajoute à ce mélange inerte le diazodinitrophénol et l'explosif d'appoint, et
* on homogénéise le mélange ainsi obtenu. - Le cas échéant, en plus des explosifs, on ajoute au mélange inerte une solution de liant, par exemple sous la forme d'une solution aqueuse de gomme arabique.
- L'objet de la présente invention sera décrit ci-après plus en détail en se référant à deux exemples de réalisation particuliers donnés à simple titre d'illustration.
- On pèse les ingrédients non explosifs : oxyde cuivrique, aluminium et poudre de verre et on les introduit dans un mélangeur rotatif où ils sont brassés jusqu'à homogénéité. On les transvase ensuite dans un malaxeur planétaire pour compositions humides, on ajoute la quantité d'eau nécessaire puis on verse par dessus le diazodinitrophénol et le tétrazène préalablement pesés et enfin une solution aqueuse de gomme arabique jouant le rôle de liant. Les différents constituants pulvérulents sont généralement utilisés avec une granulométrie moyenne inférieure à environ 250 µm. On malaxe pendant le temps nécessaire. La composition est alors prête à l'emploi, elle renferme les pourcentages en poids sec suivants :
Diazodinitrophénol 29,8 % Tétrazène 19,8 % Oxyde cuivrique 29,8 % Aluminium en poudre 9,8 % Poudre de verre 9,8 % Gomme arabique 1,0 % - Cette composition est ensuite distribuée par tartinage selon la méthode classique dans des alvéoles d'amorce de diamètre 4,45 mm de façon à obtenir des charges de 18 ± 2 mg par amorce. On met en place à l'aide d'un poinçon plat un disque de papier puis on sèche les amorces et on comprime selon la méthode classique avec une force pressante de 150 daN sur chaque amorce. Après vernissage on met en place l'enclumette et on termine le séchage. Ces amorces sont ensuite testées en sensibilité sur un montage de tir pour amorces :
Percuteur à pointe arrondie 0̸ 2 mm
Bille de 55 g
Hauteur de chute 220 mm
Résultat : sur 50 charges d'amorçage testées, toutes fonctionnent - On monte également des amorces sur étuis de calibre .38sp qu'on teste sur un mouton de chute avec la même bille. La hauteur moyenne de fonctionnement H obtenue est de 140 mm, avec un écart-type estimé S de 22 mm, ce qui donne un H+5S de 250 mm et un H-2S de 96 mm.
- Des cartouches de .38sp sont confectionnées avec les amorces ci-dessus, 430 mg de poudre BA9 et des balles semi-blindées tronquées. Elles sont ensuite tirées au pistolet Smith et Wesson mle 58G. Elles donnent une vitesse initiale de 300 ± 5 m/s, ce qui est parfaitement correct.
- On prépare de la même manière que précédemment une composition selon la seconde variante de l'invention contenant :
Dinitrobenzofuroxanne de potassium 44,8 % Diazodinitrophénol 14,8 % Oxyde cuivrique 19,8 % Fer en poudre 9,8 % Poudre de verre 9,8 % Gomme arabique 1,0 % - Cette composition est distribuée par tartinage dans des étuis pour percussion annulaire de calibre .22 ou 6 mm ou 9 mm ou autre et répartie par compression ou turbinage ou tout autre moyen mécanique, dans le bourrelet de ceux-ci. Ces étuis sont testés pour leur sensibilité à la percussion : la chute d'une bille de 111,7 g sur le percuteur à partir d'une hauteur de 200 mm provoque un fonctionnement certain, ce qui est considéré comme satisfaisant pour ce type de munitions.
