| 简介 |
The present invention has as an aim of the generating pyrotechnical gas compounds as well as a process for their obtaining. The aforementioned compounds can be obtained uninterrupted by extrusion and present a composition which contains, in a réticulé oxygenated bitumen binder, an oxidizing load : - the aforementioned oxidizing load including/understanding a principal oxidizing load made up of at least an organic perchlorate and, for to the maximum 10% in mass (of the total mass of the composition), a complementary oxidizing load made up of at least a nitrate chosen among alkaline and alkaline-earth nitrates; - the aforementioned réticulé oxygenated bitumen binder, having been obtained by reticulation of an elastomer in the presence of to less the one reticulating agent and of at least an oxygenated hydrocarbon plasticizer of known as elastomer; the aforementioned elastomer, preferentially selected among polyesters and polyacrylates, having a molecular mass higher than 200.000 and the aforementioned at least hydrocarbon plasticizer oxygenated being selected among the plasticizers, whose molecular mass is higher than 350 g/mol and balances it out of oxygen equal or higher than -280% and lower or equalizes to -235%, and their mixtures; and - the aforementioned composition not containing a nitrogenized organic compound. |
