Abstract

L'invention se situe dans le domaine militaire des munitions explosives. Elle a pour objet un procédé semi-continu d'obtention d'un chargement explosif composite à matrice solide polyuréthanne chargée dont la charge est pulvérulente et comprend au moins un explosif nitré organique, par introduction dans un moule d'une composition explosive pâteuse puis réticulation thermique de cette composition.
La composition est obtenue par mélange de constituants comprenant essentiellement un prépolymère polyol, un plastifiant, un monomère polyisocyanate et une charge solide pulvérulente comprenant au moins un explosif nitré organique. Plus précisément, on réalise tout d'abord, à partir de l'ensemble des constituants, 2 composants :
  • un composant A pâteux comprenant la totalité du prépolymère polyol et la totalité de la charge solide pulvérulente,
  • un composant B liquide comprenant la totalité du monomère polyisocyanate,
   le plastifiant étant indifféremment réparti entre les 2 composants A et B.
On mélange ensuite, de façon continue, le composant A et le composant B de telle sorte que le rapport massique composant A / composant B soit constant et compris entre 95/5 et 99,5/0,5.
Ce procédé simple et économique permet de s'affranchir, sans inconvénient, du compromis vie de pot / durée de cuisson de la composition.
