Abstract
The invention relates to a gas-generating pyrotechnical composition and pyrotechnical compounds which can be obtained from said composition. The compound comprises copper nitrate, guanidine nitrate, a specific additional reducing charge and/or a specific additional oxidizing charge, in addition to a specific binder.
Description
The present invention relates to pyrotechnic gas and produce, particularly in the swelling gasbag that in the system of protection passenger, uses.More specifically, the present invention relates under the acceptable temperature of motor vehicle security to produce the pyrotechnic composition of rich nitrogen and nontoxic, clean what is called " cold " gas, also relate to the firework mixture that can obtain by these compositions.
Because different pyrotechnics demand, particularly guarantee the expansion that air bag is correct, pyrotechnic gas generator must provide pure gas in the short period of time at the utmost point of 30 milliseconds of orders of magnitude, promptly do not contain the solid particulate that might constitute focus (hot spot), this solid particulate may damage airbag wall, and gas is nontoxic, promptly contains a spot of nitrogen oxide, carbon oxides and chlorizate.
U.S. Pat-A-5608183 discloses the pyrotechnics gas-generating agent composition, and this pyrotechnics gas-generating agent composition comprises the reductibility filler (charge) that is made of Guanidinium nitrate (GN) of predetermined proportion and the oxidisability filler that is made of basic copper nitrate (BCN).This composition has superiority very much, because they burn being lower than under the 2000K low temperature, allows them to be used for the producer gas generator of air bag, also because they can produce high gas yield in its combustion processes.
Yet for example US-A-6143402 describes, and this composition has low rate of combustion, particularly owing to there is Guanidinium nitrate (also referring to US-A-6550808 the 3rd hurdle) in composition.In addition, have been noted that this composition is difficult to light, and they have low-down temperature of combustion, this has significantly reduced their swelling capacity (power) (" swelling capacity " is defined as the incendiary gas yield and multiply by the long-pending of its temperature of combustion).When being used for the vehicle safety field with swelling gasbag, the temperature of combustion of composition must keep low temperature, if possible is lower than 2200K.In fact, being lower than the temperature of 2200K, still can use air bag with uncoated inwall.From the viewpoint of cost, this may be in the competition of automobile market be have conclusive.Yet too low temperature of combustion is totally unfavorable for combustion power.
European patent application EP-A-1279655 and EP-A-1130008 have described the method for producing the aerogenesis mixture.Provide applicable to as the component of those mixtures, as the reductibility filler, as the oxidisability filler with as the long list of the material of additive.The preparation of minor diameter simple perforation integral body (monolithic) mixture has been described in a general way.
Therefore, target of the present invention is to provide extrudable pyrotechnic composition (it is applicable to preparation list or multiple punching whole mixt usually), this pyrotechnic composition can be lower than the clean nontoxic gas of generation under the low temperature of 2300K, allow it to be used to the uncoated air bag that expands, said composition is lighted easily, and has satisfied swelling capacity.
Realize this target by following pyrotechnics gas-generating agent composition, this pyrotechnics gas-generating agent composition comprises: by the oxidisability filler of basic copper nitrate (BCN) formation and reductibility filler and the binding agent that is made of Guanidinium nitrate (GN), said composition is characterised in that also and comprises:
Be selected from trimethylene-trinitramine (RDX), tetramethylene tetranitro amine (HMX), trinitrol (PETN), nitric acid triaminoguanidine (TAGN), nitroguanidine, 3-nitro-1,2,4-triazole-5 ketone (ONTA) and single-and the additional reductibility filler of two-tetrazolium; And/or, favourable and
Additional oxidisability filler by the formation sosoloid that obtains with Guanidinium nitrate (GN) displacement; And
Mierocrystalline cellulose is water miscible, and being based on mass ratio is at least a high molecular carboxymethyl cellulose of 95/5-60/40 and the mixture of at least a lower molecular weight carboxymethyl cellulose.
According to the present invention, select to have formula Cu (NO
3)
23Cu (OH)
2Basic copper nitrate (hereinafter BCN) as oxygenant, because it is highly stable and combine burning with reductive agent and form the advantage that is easy to filtering copper resistates.In addition, BCN is soluble in water, and this is favourable when composition uses water-soluble binder, and this permission is prepared by extruding.BCN also has the satisfied gas yield of compound that is higher than copper oxide for example, with relative high+30% oxygen residue.
In the favourable enforcement of the present invention, the massfraction that basic copper nitrate (BCN) exists is the 40%-60% (the particularly advantageous 50%-60% of being) of whole composition qualities.
According to the present invention, the reductibility filler of selection is Guanidinium nitrate (GN).Guanidinium nitrate (GN) is rich nitrogen, stable and cheap organic compound.Detected in 400 hours 107 ℃ of tests, Guanidinium nitrate (GN) has good aging resistance.In addition, in composition, exist Guanidinium nitrate (GN) to improve the gas yield of composition.Guanidinium nitrate (GN) has negative Enthalpies of Formation, also has the effect that reduces the composition burn temperature.
In the favourable embodiment of the present invention, the massfraction that Guanidinium nitrate (GN) exists is the 20%-55% (the particularly advantageous 20-40% of being) of whole composition qualities.
The additional reductibility filler that exists in the present composition improves gas yield significantly and promotes lighting of described composition, therefore makes it more reliable, and has avoided lighting filler.It is expensive lighting filler; Therefore, use composition of the present invention can reduce the cost that gas is instead given birth to device.
In preferred embodiment, the additional reductibility filler of selection is trimethylene-trinitramine (RDX) or tetramethylene tetranitro amine (HMX).，
When having described additional reductibility filler, with respect to whole composition qualities, massfraction is less than 15% usually.
The specific additional oxidisability filler that exists in the present composition can be especially:
Improve gas yield;
Promote lighting of described composition; And can also
Improve the rate of combustion of described composition.
It has also promoted the described method for compositions of preparation and by the enforcement of the method for described preparation of compositions mixture.
Therefore, the additional oxidisability filler that can use is not an oxidisability filler arbitrarily.Its selection is to form by replacing the sosoloid that obtains with Guanidinium nitrate (GN).
This class is known to those skilled in the art just by the sosoloid that displacement (molten altogether) obtains itself.Described chemical substance (Guanidinium nitrate and second oxygenant in the present circumstance) must have:
Similar molecular dimension;
The crystal lattices of same type; With
Identical valence state (or Oxidation Number).
Surprising, the contriver has been found that the importance of this class sosoloid in literary composition of the present invention.To the rate of combustion important influence.
In the pyrotechnics field in the already used multiple known oxygenant, have only those oxygenants that form by the sosoloid that obtains with the Guanidinium nitrate displacement to be applicable to composition of the present invention.Particularly, ammoniumper chlorate, potassium perchlorate, ammonium nitrate, SODIUMNITRATE and saltpetre are fit to.Ammoniumper chlorate and potassium perchlorate are particularly suitable.The use of ammoniumper chlorate is special recommendation.These special oxygenants are discussed hereinafter.
Usually, when having described additional oxidisability filler, massfraction is less than 15% of whole composition qualities, and favourable is less than 10%.
Ammoniumper chlorate is very strong oxygenant and has extraordinary gas yield.Its high oxidation character allows to improve the ratio of reductibility filler in composition, therefore improves the ratio of Guanidinium nitrate (GN) in composition, and GN also has extraordinary gas yield.Resemble additional reductibility filler, the ammoniumper chlorate that exists in composition can promote lighting of composition.In the vehicle safety field, nearly all pyrotechnic composition must be under the pressure of 20MPa (MPa) order of magnitude, in 30ms (millisecond)-40ms (air bag that is used for passenger or officer) or 20ms (being used for installing side airbag) internal combustion.Be used for the composition of vehicle safety, must satisfy these combustion times.When having ammoniumper chlorate, ammoniumper chlorate is as " secondary accelerator " of composition.
In addition, when the pyrotechnics product that obtains burns in parallel layer, law below rate of combustion Vc satisfies:
V
c＝a*p
n
Wherein, a is that constant n is a pressure index.The burning of firework mixture at first is a chemical reaction, therefore depends on temperature.Use ammoniumper chlorate can reduce pressure index, this make composition still less depend on pressure and therefore still less depend on temperature.In the present invention, pressure index is low especially, is lower than 0.7 significantly, this means that the temperature at-35 ℃-85 ℃ can make this pyrotechnic compound play a role.Therefore composition of the present invention can be used in the motor vehicle.
Although ammoniumper chlorate or potassium perchlorate are strong oxygenants and have favourable combustionproperty that the use in composition can cause the generation of high temperature of combustion and produce the combustion gases that can contain quite high-level hydrogenchloride.For fear of these problems, what recommend very much is to use these oxygenants on a small quantity, usually less than 15%, preferably is less than 10% (with respect to the quality of composition).In conjunction with the use of the additional oxygenant that is fit to arbitrarily, having provided these maximum values with general fashion is 15% or 10% indication.
Composition of the present invention also can comprise the decomposition of transition metal oxide with the additional oxygenant of catalysis.Described transition metal oxide is the oxide compound of iron, copper and manganese particularly, and the content that exists is less than 5 weight % usually.
Show that above composition of the present invention comprises above-mentioned additional reductibility filler and/or above-mentioned additional oxidisability filler.Favourable, they comprise described additional reductibility filler and described additional oxidisability filler.
What therefore, they were favourable comprises:
Basic copper nitrate (BCN) and additional oxidisability filler and
Guanidinium nitrate (GN) and additional reductibility filler.
Described concrete Oxidizing and Reducing Agents in the mode of feature, is included in the specific water-soluble binder.Described concrete water-soluble binder is favourable:
Because: it is water miscible.(in some patent applications, french patent application FR-A-2772370 has for example described based on silicone resin or based on the use of the crosslinked reduction binding agent of Resins, epoxy.The content that binding agent exists in said composition is favourable is the 6%-10% of whole composition weights.For be applicable to use the preparation of twin screw extruder by extruding, composition for example must have whole composition qualities 4% or 5% amount binder content and must use the solvent of binding agent.The binding agent that uses in the prior art compositions need use organic or halogenated solvent.Yet the halogenated solvent for example use of trieline will be regulated, and the production of this is complicated greatly this composition has also increased production cost.Similarly, organic solvent for example ketones solvent (for example acetone, methylethylketone etc.) need to use the volatilization of omplicated solution with control volatile organic compounds (VOC).Water-soluble binder in the present composition has avoided using this organic or halogenated solvent in granulation that relates to firework mixture or extrusion step); With
Because: it is based at least a high molecular carboxymethyl cellulose that mass ratio is 95/5-60/40 and the mixture of at least a lower molecular weight carboxymethyl cellulose, and promptly it comprises macrofiber and the staple fibre with aforementioned proportion.
High and low-molecular-weight notion limits below.Clearly, they refer to molecular-weight average.The term that uses in the application and claim " high molecular " refers to more than 250,000g/mol[gram/mol] molecular-weight average, favourable 700,000g/mol or more.The term that uses in the application and claim " lower molecular weight " refers to and is less than 100, the molecular-weight average of 000g/mol, and usually much smaller than 90,000g/mol.These definition are not unexpected for a person skilled in the art.
The carboxymethyl cellulose performance is good, because:
Good aging behavior is particularly when carrying out burn-in test detection in 400 hours for 107 ℃; With
Favourable oxygen residue.The composition that uses in the vehicle safety field must have equilibrated oxygen residue (OB).According to definition, composition is called as oxygen " equilibrated ", and said composition comprises competent oxygen so, makes all cpds of after reaction composition with CO
2, H
2O and N
2Form.The oxygen residue of binding agent must be low as much as possible.Carboxymethyl cellulose has the oxygen residue higher than elastic type binding agent.
Carboxymethyl cellulose (as defined above short and long stapled mixture) in granulation, to suppress and extrude in the operation performance good especially, and is applicable to fully composition is processed into spherical, plate-like or whole bulk, they are singly or even multiple punching.Can be prepared as follows short and long stapled mixture:
In solution, in minimal amount of water, pumpable and measurable colloidal sol is accepted a large amount of solid packings continuously; With
Indeformable extruded product under himself weight.
The common massfraction that exists in the present composition of specific water soluble binding agent is the 2%-15% of whole composition qualities as defined above.Surpassing 15%, is deleterious to composition oxygen lingering effect.
The specificity that is used for the binding agent of the present composition means and can obtain mixture by using continuous double-screw type forcing machine to extrude continuously, this mixture has the structure that is described as whole bulk (or particle) in specialty, this structure have one or more external diameters be several millimeters to about 20 millimeters perforation.For diameter 0.5mm[millimeter]-perforation of 1.5mm, the quantity of perforation can be changed by 1-19.
Composition of the present invention also can comprise additive, particularly as the incendiary catalyzer or be used for capturing the reagent of the solid particulate that combustion processes produces.Described reagent can capture the solid particulate that produces in the combustion processes and have the residue that is enough to make the size that they are filtered with generation.Be used for the compositions field of vehicle safety, known additives is aluminum oxide or silicon oxide for example, can add in the composition of the present invention.
In second aspect, the invention provides can be by the mixture of above-mentioned pyrotechnic composition acquisition.
In first changed, the firework mixture with above-mentioned composition pressed (disc compression) technology to be prepared and moulding by granulating (pelletization) or coiling.
In second changed, the firework mixture with above-mentioned composition was prepared and moulding by expressing technique.
In the present invention, the scale production of comprehensively pressing or granulate of the firework mixture with present composition.
Before the operation of granulating, must prepare the powder step.This step is not only to mix each dried component.For the operation of granulating, must obtain suitable mobile powder.This preparation step is granulation (granulation) operation, comprises the particle that is begun to make the larger particle size with hundreds of micron number magnitude by the various materials that constitute the present composition with powder type.In case the acquisition powder, the operation of just granulating.
These granulations or pressing treatment are known to those skilled in the art in itself.
In the present invention, the firework mixture with present composition also can lead to and extrudes acquisition.It is possible extruding, and is optimized by the water of carboxymethyl cellulose and interpolation.Suppose to use ammoniumper chlorate or potassium perchlorate, should add a spot of water to prevent the dissolving of described perchlorate.By extruding favourable the comprising of method for preparing firework mixture, will be pre-mixed the oxidisability filler (BCN and optionally additional oxidisability filler) of used binding agent (the concrete binding agent of use) and reductibility filler (GN and optional additional reductibility filler) and infeed for example step of duplex bar forcing machine of mixing and extrusion device continuously.After mixing, use forcing machine, the bar of extruding (section nod) cuts into required length then through baking hardening, for example is the particulate form.Under some dimensional requirements and undemanding situation, also can before baking hardening, cut.The monoblock mixture that obtains can carry out single or multiple perforation.The specificity of binding agent (short and macrofiber mixture) allows the mixture with the acquisition of multiple punching form.
