- the invention relates to a method for producing a functional high-energy Layered grain material containing a high energy plasticizer and a polymeric phlegmatizer, wherein the plasticizer and / or the Phlegmatizer in the form of an aqueous emulsion is diffused into the receptive grain will or will be. Furthermore, the invention relates to such a material.
- TLP Propellant Charge Powder
- nitrocellulose based monobasic Propellant powders have a higher kinetic energy on the ammunition component can transfer.
- the problem with providing this required new high performance TLP is now to avoid unwanted side effects, i. on the demanded increased performance level nevertheless the full extended system compatibility concerning pipe (erosion, corrosion), weapon (top gas pressures, cadence) and environment (avoidance environmentally problematic formulation components).
- the ballistic stability i. the period of time within which the with the propellant charge powder filled ammunition can be fired safely and in compliance with requirements, opposite can not be reduced to the conventional propellant charge powder.
- the required high-performance TLP can be produced inexpensively, i. starting from easily accessible, inexpensive starting materials and in particular no complicated processing processes (such as rolling processes in polybasic TLP) need.
- Another approach to increasing the energy content is to include a suitable one high-energy blasting oil to the grain matrix.
- a suitable one high-energy blasting oil to the grain matrix.
- ball powder The maximum size of the spherical Powder particles are limited. However, these powders are inherently very explosive and have acquired a technical importance, especially in the small caliber area. Moreover these powders have a strongly limited ballistic compared to monobasic TLPs and chemical stability.
- the powders have a high kinetic Muzzle energy and a high thermal efficiency.
- the layered structure of the outer skin and the inner zones of the novel causes Powder a burning behavior, which largely independent of the temperature of the powder body is.
- the functional materials have very high bulk densities.
- Bulk density is a measure of what weight of propellant powder can be accommodated in a given volume unit and is typically expressed in g TLP / l unit. This positive property is of great importance because the shell volume of a given ammunition component is given. The more powder that can be accommodated in this given tube volume, the higher the potential, which can be converted into kinetic energy. Thus, for example, with comparable top gas pressure, a muzzle energy increased by up to 12% over conventional monobasic TLP can be achieved.
- US 2 771 351 describes a powder having a surface area of 10-84 cm 2 / g with a surface Comes size of about 0.015 and 0.070 inches and one introduced into the surface Deterrent.
- the grain can z. B. be prepared by extrusion of nitrocellulose (NC).

- the Grain is then pressed to a size of 0.019 inches and dried.
- Last but not least The grain is treated with potassium nitrate, diphenyl phthalate and Dinitrotoluen and with Graphite coated.
- the post-published document EP 1 031 548 A1 relates to a method for Producing a TLP, in which a flattening of the maximum pressure curve in the Temperature range for which the weapon is intended, is reached.
- Usual one, two or one Polybasic powders are to be surface treated with phlegmatizers which are used in the Essentially have no migration.
- the surface treatment by Spraying a solution or emulsion of Phlegmatisators done. It should be substances such as Non-energetic polyesters, energetic polymers, alkylnitratoethylnitramines, Dinitrodiazaalkane, nitric acid esters, etc. are used.

- US Pat. No. 5,682,009 proposes a green grain on the basis of nitrocellulose a thermoplastic polymer as phlegmatizer diffuse.
- a thermoplastic polymer as phlegmatizer diffuse.
- the preparation of the TLP becomes an aqueous with the powder Suspension to which a non-aqueous solution of the thermoplastic Phlegmatizer is given.
- Has the phlegmatizer penetrated into the grain with am Edge is the highest concentration, the solvent is removed.
- US 5 520 757 is concerned with the preparation of blends with alkyl NENA and DINA and its use for a NG-based TLP.
- the object of the invention is to provide a method of the type mentioned, which the precise adjustment of the layer structure allows.
- the plasticizer and / or the phlegmatizer in the form of an aqueous emulsion in one Diffusion depth in the range of 100-500 ⁇ m into the receptive (unimpregnated) grain, i.e. diffused into the so-called green powder.
- the invention is based on the surprising finding that the impregnation for Production of the functional materials can also be carried out in an aqueous emulsion, wherein TLP also result in the desired layered construction.
- the present invention therefore includes the process of impregnating an untreated one monobasic green powder in aqueous emulsion, and the subsequent completion to provide the functional, layered TLP.
- the invention thus differs significantly from the known methods, in which Impregnations by means of which the layered distribution of the explosive oil and the Let phlegmatizers set specifically, typically in so-called polishing drums be performed.
- highly sensitive explosive oils such as nitroglycerin due to acute safety risks would arise and the production of larger quantities of functional high-energy Considerably complicating, if not destroying, materials avoided in the inventive method.
- the impregnation process can be carried out in a 2-stage process or in a 1-stage process be performed.
- the green grain is first in a aqueous emulsion treated with the blasting oil. After completion of the action will be pumped off the excess emulsion.
- the liquid components in the reactor can by a Drained sieve. Thereafter, the (remaining in the reactor) powder mass in a further process step of an aqueous emulsion containing the polymeric phlegmatizer exposed. This procedure allows a good control of the process parameters.
- the green grain is first with a aqueous emulsion of the blasting oil. After completion of the exposure time, the remaining emulsion but not separated from the powder, but with the addition of the polymeric Phlegmatisators continue to be used. By varying the addition times of the blasting oil or the polymeric phlegmator and the time point, the concentration profiles be selectively changed.
- the 1-step process involves fewer process steps and is therefore more economical.
- the aqueous emulsion used can be used both in the 1-stage and in the 2-stage process if necessary, known auxiliaries (stabilizers and / or wetting agents) added which, inter alia, suppress foaming, stabilize the emulsion or can specifically influence the penetration of the components of action.
- auxiliaries stabilizers and / or wetting agents
- layered TLPs are obtained which have similarly advantageous properties as the materials described in EP 0 960 083 A1, ie over the entire temperature range, a markedly increased power potential can be achieved under arms-compatible conditions (see Table 1).
- Another aspect of the present invention is the provision of novel functional ones Materials that improved over the materials described above Have properties.
- K. Ryf Int. Annu. Conf. ICT (1998), 29th (Energetic Materials), 38.1-38.14
- Impregnation exclusively using blasting oils such as nitroglycerin.
- One such disadvantage is the extremely high sensitivity of these blasting oils.
- nitroglycerin and dinitrodiglycol each have a sensitivity to impact of only 0.2 Nm, what their handling during processing severely hampered and restricted.
- blasting oils Another disadvantage of these blasting oils is their high Energy content (explosion heat), for nitroglycerin 6542 J / g and for dinitrodiglycol 4527 J / g. If the powder now contains larger quantities of these blasting oils, it increases during combustion, the flame temperature and hereby leads to an increase in pipe erosion.
- blasting oils can be replaced in the impregnation process by energetic plasticizers, which have a lower energy content and advantageous thermodynamic properties and which are additionally less sensitive to impact.
- the resulting novel powders are surprisingly characterized by a significantly improved ratio of Vo / Pmax, ie when using the pressure reserves higher muzzle velocities can be realized.
- functional materials also have a favorable ratio of ⁇ Vo gTLP / ⁇ Pmax gTLP , ie, per gram charge increase, the muzzle velocity increases more than the pressure on TLP based on blasting oils. This effect is illustrated in Example 3 below.
- energetic plasticizers include in particular low molecular weight aliphatic nitric acid esters, nitro compounds, nitramines and azides.
- a particularly suitable substance class form the so-called 2-nitroxyethyl-nitramaine (alkyl-NENA) having the general structural formula I, wherein R 1 represents an aliphatic radical.
- alkyl-NENA 2-nitroxyethyl-nitramaine
- Another particularly suitable class of substances for this purpose form the so-called dinitro diazaalkane of the general formula II, wherein R 2 and R 3 are aliphatic radicals.
- the present invention also relates to novel functional materials which additionally contain a crystalline energy carrier in the basic matrix of nitrocellulose.
- crystalline energy carriers are known per se. These are, for example, so-called crystalline nitramines of general formula III.
- the radical R 4 forms part of a ring system and may preferably contain further units of the structure (-CH 2 -N-NO 2 ).
- Particularly preferred compounds of structure III are Hexogen IV, Oktogen V and CL-20 VI.
- the upper limit of the content of crystalline energy is such that the obtained mechanical strength of the resulting powder grain even at low temperature remains. To detect the expected positive effect ballistically, the amount should not be less than about 5%.
- These compounds of general structure III or mixtures thereof are therefore used in amounts of between. 5-80%, preferably 10-50% of the total powder mass, the nitrocellulose matrix mixed and are homogeneously distributed in the finished grain.
- the thus pretreated powders (which functionally correspond to the green powder) become then by an impregnation process, which the previously described Layerwise grain structure results and is also part of the present invention, treated with an energetic plasticizer and a phlegmatizer.
- This stratified functional material is that it faces the functional materials, which do not contain any crystalline energy carrier in the grain matrix contain an increased Energyinhait, which thanks to the special Layer structure optimally converted into kinetic energy in a system-compatible manner can be.
- the impregnation process for the production of high-energy functional materials is described below.
- the impregnation process goes from untreated Green powder of any form, which consists essentially of nitrocellulose with an N content between 11-13.5% exists.
- the green powder used can optionally in the powder technology known additives for stabilization, pipe protection, softening and fire damping contain.
- Known additives which are suitably used For increasing stability for example, sodium hydrogen carbonate (CAS #: 144-55-8), calcium carbonate (CAS #: 471-34-1), magnesium oxide (CAS #: 1309-48-4), acardite II (CAS #: 724-18-5), Centralit I (CAS #: 90-93-7), Centralit II (CAS #: 611-92-7), 2-nitrodiphenylamine (CAS #: 836-30-6) and diphenylamine (CAS #: 122-39-4), for plasticizing about diethyl phthalate (CAS #: 84-66-2), camphor (CAS #: 76-22-2), dibutyl phthalate (CAS #: 84-74-2), Di-n-propyl adipate (CAS #: 106-19-4) or methylphenylurethane (CAS #: 261-79-6), for Tube protection about magnesium oxide (CAS #: 1303-48-4), molybdenum trioxide (CAS #: 1313-27-5), Magnesium silicate (CAS #: 14807
- the green powder Still other known additives, such as to improve the Anzünd s and Modulation of the burning behavior, included. All the mentioned accessories are during the green grain preparation has been added to the powder dough, i. they are even in distributed the grain matrix.
- the total amount of these additives in the green grain is between 0-20% the nitrocellulose, preferably between 5-15%.
- the green powder is typically cylindrical single or multi-hole powder with a diameter / grain length ratio between 0.5-2.0, preferably 0.9-1.5.
- the Outer diameters of the green powders are in the range between 0.5 and 10 mm, preferably 0.5-5 mm.

- the green com can open known manner by compression of a solvent-containing powder dough in a strand press or by extrusion.
- the production process according to the invention can be one-stage or two-stage.
- Impregnation process should first be clarified in the 2-step process:
- the above described green powder is placed in a metallic reactor vessel, which with Lid inlet valve, bottom outlet valve, mechanical and static flow internals and connections is equipped for vacuum and which with 1-5 times the amount Water (compared to the amount of powder to be treated) is charged.
- the powder can first with stirring for 4-24 hours at a temperature of 20-85 ° C pre-bathed become. Thereafter, for a period of 10-60 minutes, a solution of the Sprengöls (about 20% dissolved in a suitable solvent) was added, wherein the proportion of the Blasting oil is compared to the used green grain in the range of 3-20%.
- the 1-stage process is analogous to the 2-stage process described above with the only difference that after completion of the exposure time of blasting solution the liquid components remain in the reactor and directly to the phlegmatizer emulsion is added.
- the addition times By varying the addition times, the exposure times and the time the pressure reduction can reduce the burning characteristics of the finished powder be specifically influenced.
- Suitable explosive oils may be nitroglycerin (CAS #: 55-63-0) or diethylene glycol dinitrate (Dinitrodiglycol, CAS #: 693-21-0). It's a lot of connections possible, which can be used as suitable phlegmatizers. On the one hand the affinity with the nitrocellulose must be such that the phlegmatizer will react with the appropriate Solvent as transport medium (carrier) diffuse into the powder grain can. On the other hand, after the removal of the solvent no further diffusion which would lead to a change in the distribution profile.
- organic ether and ester compounds having a molecular weight between 100-100,000, preferably between 1000-10,000.
- a hitherto unknown novel class of functional energetic materials is obtained by replacing the blasting oils described above with less impact-sensitive (in simplified terms: "insensitive") energetic plasticizers of the general structures I or II.
- these novel functional materials are distinguished by a particularly favorable ratio of Vo / Pmax.
- such functional materials have a favorable ratio of ⁇ Vo gTLP / ⁇ Pmax gTLP , ie, per gram of charge increase, the muzzle velocity increases more than the pressure than the layered TLP based on blasting oils.
