Definitions
- the invention relates to a method for producing castable plastic-bound Explosive charges or rocket fuels according to the preamble of claim 1.
- Plastic-bound explosive charges have a high active power relatively high insensitivity. They consist of reaction polymers in the front curing crystalline explosives, such as octogen, hexogen, pentaerythritol tetranitrate etc., can be incorporated. The polymer content is about 10 to 20 Wt .-%.
- a problem with the manufacture of plastic explosive charges is that with increasing solids content, i.e. with increasing proportion of explosive, the viscosity of the mixture can 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 is approx. 90% by weight.
- explosive charges with one high solid content can only be poured if the grain sizes are suitable for the explosive charge explosive crystals used within a predetermined diameter interval lie, so that a relatively costly screening of grain fractions is required.
- the respective explosive charge 0.1 to 10% by weight of fine-grained vanadium, Niobium, tantalum, chromium, molybdenum or tungsten powder or a mixture from two or more such powders, the powder grains being one should have a substantially spherical shape.
- this metal powder which due to the spherical shape of the powder grains a very small specific Surprisingly, surface has been shown to be like liquid Lubricants act between the coarser-grained explosive particles (tribological Effect), so that relatively low viscosities result.
- the invention has for its object a method for producing less sensitive pourable plastic-bound explosive charges or rocket fuels with a high (e.g. 90%) solid content, with which an increase the viscosity due to polar deposits on the metal surface of the metal powder Groups is avoided.
- the polar groups can no longer react with the isocyanates and the specific surface area of the respective metal powder is reduced.
- the viscosity of the explosive charge also drops.
- All alkyl and aryl radicals are suitable as organic radicals, the alkyl radicals being more reactive.
- tungsten powder (grain size between 3 and 5 ⁇ m) was placed in a solution of 900 g of pentane and 20 g of trimethylchlorosilane and stirred for 5 minutes. The tungsten powder was then filtered off and dried in a drying cabinet. While the specific surface area before the treatment with Me3SiCl was 0.1978 m 2 / g, it was only 0.1880 m 2 / g after the treatment, which subsequently reduced the viscosity of the explosive mixture from approx. 600 - 800 Pas to approx 400 Pas led.
- the grain size of the respective metal powder should be between 0.1 and 5 ⁇ m lie.
