Definitions
- the present invention relates to large pyrotechnic grains based on binder-free formulations, to their production, and to their use. More precisely, it relates to:
- Gas generation has a number of applications, both in the civilian and in military fields.
- compositions with a high combustion rate In the automotive safety sector, gas generators have been developed with a short operational duration, which use compositions with a high combustion rate. Those compositions are in the form of thin pellets (1 mm [millimeter] to 3 mm) with a small diameter (3 mm to 7 mm). This provides them with a large combustion surface, encouraging a high rate over a short period (necessary for airbag applications in automotive safety, of the driver's airbag type). The porosity of such pellets is generally less than 4%. Pelletization operations carried out to produce said pellets are well known, similar to those used in medicinal formulations. Compositions based on guanidine nitrate and basic copper nitrate have been used in that context (United States patent U.S. Pat. No. 5,608,183). An attempt has even been made to improve the combustion rate (U.S. Pat. No. 6,143,102) since said combustion rate of such compositions is rather low, compared with that of other compositions used in the same field
- That relates to the field of slow gas generation.
- a gas stored under pressure is generally used.
- the use of chemical reactions or the combustion of pyrotechnic cartridges has also been mentioned.
- the flow rate of the gas that is generated is controlled by selecting the characteristics of the propellant, the geometry of the cartridges, and/or the conditions for ejecting said generated gas, etc.
- the present invention falls within the context of generators operation providing long duration, low flow rate, and low operating pressure.
- the present invention proposes pyrotechnic grains that are simple in shape and that satisfy the following specifications:
- a long combustion period 50 ms [millisecond] to 1 min [minute] due to a slow combustion rate (to ensure a long period of operation) and/or to a ratio of combustion area over burning thickness that is low, and/or to a low operating pressure (for use in low pressure generators and to encourage a low combustion rate);
- the pyrotechnic grains of the invention are also advantageously non-aggressive for the gas generator in which they are used and for the associated system (i.e., on combustion, they generate neither particles nor corrosive species). In the same manner, the generated species are advantageously of low toxicity.
- the pyrotechnic grain of the invention must be thick and have a small combustion area. Thus, it must be a large grain, larger than the pellets mentioned above.
- the Applicant has obtained pyrotechnic grains, from specific oxidizing and reducing charges, which are simple in shape and that satisfy the above specifications.
- Such pyrotechnic grains constitute the first aspect of the present invention.
- Said pyrotechnic grains of the invention have a composition that comprises at least one (specific) oxidizing charge and at least one (specific) reducing charge, but that includes no binder.
- they are pyrotechnic grains of the pellet type mentioned above.
- the composition of the pyrotechnic grains of the invention generally essentially consists of at least one such (specific) oxidizing charge and at least one such (specific) reducing charge. It generally essentially consists of a (specific) oxidizing charge (an oxidizer) and a (specific) reducing charge (a reducer).
- Said at least one specific oxidizing charge is selected from ammonium, potassium, sodium, barium, strontium, and basic copper nitrates, and ammonium, potassium, and sodium perchlorates, and mixtures thereof.
- it comprises basic copper nitrate and/or potassium perchlorate.
- it consists of basic copper nitrate or potassium perchlorate.
- it consists of basic copper nitrate.
- Said at least one specific reducing charge is selected from nitroguanidine, guanidine nitrate, and mixtures thereof. Preferably, it consists of guanidine nitrate.
- said pyrotechnic grains of the invention are in the form of substantially cylindrical blocks:
- Said (monolithic) blocks are large blocks, which are simple in shape and of low porosity.
- Said blocks have a substantially cylindrical shape. Generally, but not exclusively, they are circular cylinders or near (quasi) circular cylinders.
- the shape of the grains of the invention is the signature of the last step of the method by which they are obtained: a compacting step (see below).
- Said blocks may in particular consist of solid (quasi) cylinders or (quasi) cylindrical sleeves.
- the grains in question are large objects (thickness more than 5 mm, equivalent diameter (or, clearly, diameter if it is a perfect circular cylinder) of 10 mm or more), and are relatively dense (porosity in the range 1% to 8%).
- Non-limiting dimensions of said grains are detailed below.
- said thickness and said equivalent diameter are both 75 mm or less.
- said thickness and said equivalent diameter are both as precised above.
- said thickness and said equivalent diameter are both in the range 10 mm to 60 mm (values of 10 mm and 60 mm being included).
- the porosity of the blocks is in the range 1% to 8% (it should be noted here that this parameter, expressed as a percentage, corresponds to the ratio between the actual density and the theoretical density; it is in fact the difference from the theoretical density).
- Said porosity is advantageously 5% or less. It should be recalled that the lower said porosity, the lower the dependency of the rate of combustion on the operating temperature of the grain.
- the pyrotechnic grains of the invention which are simple in shape, being substantially cylindrical, may in particular consist of solid cylinders or sleeves.
- the equivalent internal diameter of said sleeves is advantageously more than 10 mm; preferably, it is in the range 12 mm to 35 mm (that implies obviously a greater equivalent diameter of the sleeve).
- composition of the pyrotechnic grains of the invention the following non-limiting details can furthermore be given.
- the said composition of the pyrotechnic grains of the invention advantageously includes basic copper nitrate as the oxidizing charge and guanidine nitrate as the reducing charge. Highly advantageously, it comprises basic copper nitrate as the only oxidizing charge and guanidine nitrate as the only reducing charge.
- said basic copper nitrate/guanidine nitrate combination is known to have a combustion rate that is rather low relative to that of other compositions used in this field.
- said composition generally comprises:
- the additives in question are chemical compounds that are known per se as well as for their beneficial involvement in the general production of pyrotechnic grains.
- they may be:
- the present invention provides the production of large pyrotechnic grains, as described above.
- the method in question comprises a series of steps that are known per se.
- the method of producing pyrotechnic grains of the invention comprises carrying out the following steps in succession:
- At least one of the charges used in the powder state has a median diameter that is substantially larger than that which is used in the prior art to prepare pellets (of small dimensions).
- a median diameter that is substantially higher ( ⁇ 4, ⁇ 6) than that known to be used in the preparation of prior art pellets.
- a reducing charge with a median diameter of 200 ⁇ m [micrometer] or more be used.
- guanidine nitrate with a median diameter of 200 ⁇ m to 300 ⁇ m be used. Said guanidine nitrate is conventionally used for the fabrication of pellets, with a median diameter of 50 ⁇ m.
- the granules selected are those that have a median diameter of more than 200 ⁇ m, preferably in the range 500 ⁇ m to 1000 ⁇ m. It is thus recommended, in the context of the present invention, that basic copper nitrate/guanidine nitrate granules with a median diameter in the range 500 ⁇ m to 700 ⁇ m or potassium perchlorate/guanidine nitrate granules with a median diameter in the range 500 ⁇ m to 1000 ⁇ m be selected.
- a pressure in the range 15 ⁇ 10 6 Pa [pascal] to 35 ⁇ 10 6 Pa is applied for 0.1 s [second] to 30 s.
- the method of the invention is very advantageously carried out with all the above advantageous embodiments, i.e.
- the method of the invention is advantageously carried out with a combination of basic copper nitrate or potassium perchlorate/guanidine nitrate; highly advantageously, it is carried out with a basic copper nitrate/guanidine nitrate combination.
- the combustion rate of compositions based on these two elements BCN/NG is reduced.
- the teaching of the present invention thus goes against that of U.S. Pat. No. 6,143,102.
- the present invention provides a method of generating gas, the method comprising, in conventional manner, the combustion of at least one pyrotechnic grain.
- said method of the invention comprises the combustion of at least one pyrotechnic grain as described above (large pyrotechnic grain) and/or produced using the method described above.
- Said gas generation method is carried out in a suitable device which, in particular, has a combustion chamber adapted to the dimensions of the original pyrotechnic charge, based on large pyrotechnic grains.
- said device comprises:
- Pyrotechnic grains of the invention were prepared from the following starting materials:
- the intimate mixture of powders obtained was dry granulated in a Sahut Conreur® type granulator (an Alexanderwerk® type granulator would also have been suitable). Said intimate mixture of powders was forced through a screen. The granulometric distribution of the granules obtained was from 10 ⁇ m to 1000 ⁇ m.
- the granules obtained were then sieved, and those with a mean diameter of more than 200 ⁇ m were selected.
- Said selected granules were then compacted on a 35 (metric) tonne single action press.
- the compacting pressure applied was 230 bars (23 ⁇ 10 6 Pa). It was applied for 10 s.
- Pyrotechnic grains in accordance with the invention were obtained, which grains were cylindrical monoliths (shape of mold) with a thickness of 10 mm, a diameter of 24.6 mm, and porosity of 3%.
- cylindrical grains were prepared as follows:
- FIG. 3 With the prior art pellet, as expected, an operating peak was obtained ( FIG. 3 ). With the blocks of the invention, the desired spread over time was observed ( FIGS. 1 and 2 ).
