Definitions
- the invention relates to a process for producing pourable plastic bound Explosive charges according to the preamble of claim 1.
- Plastic-bound explosive charges have a high active power despite a high relatively high insensitivity. They consist of reaction polymers in the pre curing crystalline explosives, such as octogen, hexogen, pentaerythritol tetranitrate etc., to be incorporated. The polymer content is about 10 to 20 Wt .-%.
- a problem in the production of plastic-bound explosive charges is that that with increasing solids content, i. with increasing proportion of explosive, the viscosity of the mixture may increase so that pouring of this mixture becomes impossible.
- the theoretical limit for a flowable mixture is 92 Wt .-%.
- the practical limit for flowable Mixtures at about 90 wt .-% is.
- explosives are with such a high solids content only pourable if the particle sizes of the explosive charge used explosive crystals within a given diameter interval lie, so that a relatively expensive screening of grain fractions is required.
- From DE 38 04 396 C1 is a process for the production of plastic-bound Explosives known in which to increase the solids content without Viscosity increase of the pourable explosive charge is proposed to the mixture from explosive and other solids as well as the hardenable plastic before or during the mixing process, a proportion of the solid as Add finest grain.
- the finest grain fraction should be 0.1 to 10%, based on the weight of all solids, and the mean grain size of the Feinstkorns less than 25 microns, preferably less than 8 microns, amount.
- the Feinstkornanteil can be made of an explosive (Oktogen or Hexogeb), a Oxygen carriers (nitrates or chlorates) or fuels (aluminum powder) consist.
- the invention is based on the object, a method for producing insensitive pourable plastic bonded explosive charges with a high (e.g. % solids), which is sufficient for casting the explosive have low viscosity, without previously screening the grain fraction is required.
- the invention is based essentially on the idea of the respective explosive charge 0.1 to 10 wt .-% fine-grained vanadium, niobium, tantalum, chromium, molybdenum or Add tungsten powder or a mixture of two or more such powders, wherein the powder grains are to have a substantially spherical shape.
- this metal powder due to the spherical shape of the powder grains have a very small specific surface, has surprisingly shown to be like liquid lubricants between the coarser-grained explosive particles act (tribological effect), so that relatively low viscosities between 400 and 1200 Pas at 50 ° C result.
- the percentage of metal powder depends on the special surface of the Metal powder and the grain size and is according to experience preferably between 2 and 5 wt .-%, while the grain size is between 0.1 and 5 microns.
- the explosives are preferably octogen (HMX), hexogen (RDX) and Pentaerythritol tetranitrate (PETRIN) has proved beneficial.
- HMX octogen
- RDX hexogen
- PETRIN Pentaerythritol tetranitrate
- the explosive charges according to the invention are produced by means of the following typical formulations: 80-88% by weight Crystalline explosive, eg RDX or HMX 10-20% by weight Binder, eg HTPB 5-10% by weight softener 0.01-02% by weight bonding agent 0.05-05% by weight coating aids 0.1-1.0% by weight antioxidant 0.1-10% by weight metal powder
