Definitions
- the present invention relates to a priming composition for incorporating a pyrotechnic chain to provide ignition, separation or destruction.
- a priming composition is a mass of a detonating material that will be used to transform a generally mechanical action, for example percussion, into a pyrotechnic action, causing the ignition of a charge of powder or explosive.
- the invention will be more particularly described in an application to hunting or sports cartridges, but it is not limited to this use and may be suitable for any system of deformation by explosion, for example in the automotive industry, to the ignition for an airbag or seat belt pretensioner.
- lead-free initiating compositions have been developed with an explosive fraction consisting of mixtures of diazodinitrophenol and tetrazene, in a proportion of tetrazene of up to 40% for each of them, by weight relative to the total weight of the composition.
- FR-A-2,730,991 discloses an initiator composition for small arms cartridges comprising 20-40% by weight of diazodinitrophenol and 5-20% by weight of tetrazene, and an oxidation-reduction system comprising metals and tin oxides .
- EP-A-1 216 215 discloses an initiator composition comprising 5-40% by weight of an explosive selected from nitroesters and nitramines, 5-40% by weight of tetrazene, an oxidation-reducing system, an agglomerating agent and a friction agent.
- the preferred compositions described still comprise an explosive fraction having a proportion of at least 50% by weight of the composition.
- tetrazene or 1 (5-tetrazolyl) -4-guanyl tetrazene hydrate
- tetrazene or 1 (5-tetrazolyl) -4-guanyl tetrazene hydrate
- the explosive fraction thus obtained is lead free.
- the use of tetrazene as the primary primary explosive or as the only primary explosive makes it possible to lower the proportion of the explosive fraction in the priming composition.
- the invention relates to a priming composition which comprises at least (a) an explosive fraction which comprises at least one primary explosive, (b) an oxidation-reducing system and (c) an agglomerating composition in which the explosive fraction represents from 9 to 35% by weight of the composition, and the primary explosive at least is tetrazene which represents at least 95% by weight of said explosive fraction.
- the tetrazene represents at least 99% by weight of the explosive fraction.
- a composition of the invention is thus obtained by a simplified method which avoids having to use an additional line of synthesis of another primary explosive, said composition being effective, even in the absence of any other primary explosive, or even secondary explosive.
- a preferred industrial process for obtaining tetrazene comprises the reaction, with stirring, of an aqueous solution of a nitrite salt, for example sodium nitrite, and an aqueous solution of a neutral salt of guanidine, for example a guanidine sulphate, in the absence of mineral acid, and optionally in the presence of acetic acid and / or crystallization agent.
- a nitrite salt for example sodium nitrite
- a neutral salt of guanidine for example a guanidine sulphate
- a process is implemented according to which the tetrazene is formed in situ.
- a salt of nitrite and a neutral salt of guanidine that is to say the reagents for the preparation of the tetrazene, as well as the other constitutive ingredients of the composition, are dry blended.
- An appropriate quantity of this dry mixture is then metered into the starter cell, the mixture is compressed and then moistened, this step causing the formation of the tetrazene, and finally the composition is dried.
- This process is suitable for all starting reagents for the synthesis of tetrazene, in particular sodium nitrite and / or guanidine sulphate, as well as any constituent ingredients of a composition of the invention.
- This process is very advantageous in that it combines and safe handling and environmental safety.
- the invention therefore also relates to a composition as described above, the explosive fraction of which comprises no other primary explosive than tetrazene, and a composition whose explosive fraction consists only of tetrazene.
- the explosive fraction of a composition may, if necessary, comprise at least one secondary explosive.
- This may be chosen from secondary explosives well known to those skilled in the art, and in particular from aromatic nitro explosives, such as tolite (or 2,4,6-trinitrotoluene, 2,4,6-TNT), melinite (or picric acid) and trinitroaniline (or picramide or trinitroamine benzene); nitric ester explosives such as pentrite (or pentaerythritol tetranitrite, PETN) and nitrated esters of cellulose; and nitramine explosives, such as hexogen (or cyclotrimethylene trinitramine, RDX), tetryl (or 2,4,6-trinitrophenylmethylnitramine), nitroguanidine and octogen (or cyclotetramethylene tetranitramine, HMX).
- aromatic nitro explosives such as tolite (or 2,4,6-tri
- a composition of the invention advantageously has the following characteristics, considered independently or in combination.
- the oxidizing agent (s) of the oxidation-reduction system (b) are chosen from chemically stable oxidants and in particular from nitrate of barium, zinc oxides, zinc sulphate, copper oxide, copper nitrate, manganese oxides, ferric oxides, potassium chlorate, sodium chlorate, chromium oxide, carbonates and their mixtures.
- the reductant (s) of the redox system (b) are chosen from organic reducers, metals and metal salts, celluloses and optionally nitrated cellulose derivatives.
- the reducing agent (s) of the redox system (b) are chosen from aluminum, magnesium, zirconium and antimony sulphide.
- the proportion of the redox system (b) preferably varies between 65 and 81% by weight relative to the weight of the composition.
- the binder (c) is advantageously chosen from cellulose gums such as gum arabic, gum tragacanth and gum acacia. If the binder is necessary or even essential, its proportion in the composition can be very low, it generally varies from 0.01 to 5% by weight.
- a composition may comprise at least one friction agent, which is chemically inert.
- Undit agent is for example chosen from glass powder, diamond powder, carbide powder, ceramic, nitrides such as titanium nitride.
- the proportion of the friction agent preferably does not exceed 15% by weight relative to the weight of the composition.
- a composition of the invention can be used in various fields, in particular for the manufacture of shot, hunting, sports, defense cartridges, for barreled and rifled guns, in the automotive industry for manufacture of airbags safety devices (airbags) or pretensioners, or for any other article using pyrotechnic energy, or for sealing techniques using explosive cartridges. It can also find applications in medical injection techniques, for example for the intradermal or subcutaneous administration of a drug, a vaccine.
- the proportion of the binder is low compared to those of the other constituents of the exemplified composition.
- the explosive fraction (a) in such a composition of the invention represents only 20% of said composition.
- This composition constitutes an advantageous variant of the invention in that the explosive fraction (a) consists only of tetrazene.
- the explosive fraction in such a composition represents 32-40% of said composition.
- compositions were tested under the same conditions in three tests, a percussion sensitivity test, a ballistic test and a full-scale blind ballistic test.
- This test measures the ability of a composition to respond to the percussion of the weapon and safety standards.
- a standard ball drop apparatus is used. A ball of 56 g is released from a height H on a firing pin, thus causing the explosion or not of the load.
- the priming composition is placed in a cell in which it is protected by a blotter.
- composition tested is that described at the beginning of the example, with a variation of the proportion of tetrazene indicated in the table and compensated by the proportion of barium nitrate.
- Table 1 Lot 20 20% tetrazene Lot 21 18% tetrazene Lot 22 23% tetrazene Lot 20 20% tetrazene Lot 21 18% tetrazene Lot 22 23% tetrazene Weight of the priming composition (mg) 61 61 58 68 70 72 Weight of the blotter 120 120 120 120 120 120 120 120 H (mm) 72 75 64 71 86 87 S 0.539 0.594 0.939 0,440 0.642 0.570 H + 5s 126 135 158 122 150 145
- skirt pad cartridges After having constituted skirt pad cartridges, loaded with a commercially available powder and a charge of lead, and initiated by a composition of the invention or a composition of the prior art, these cartridges are placed in an apparatus of control, called shotgun.
- Trials were carried out in triplicate on the composition of the invention, and for a lead load of 36 g and another of 32 g.
- Table 2 corresponds to tests carried out with a lead load of 36 g
- Table 3 corresponds to those carried out with a lead load of 32 g.
