Abstract

L'invention concerne des compositions pyrotechniques génératrices de gaz ainsi qu'un procédé continu permettant de les mettre en oeuvre.
De telles compositions comprennent un liant hydrocarboné, un composé organique azoté et une charge oxydante comprenant du perchlorate d'ammonium et un capteur de chlore.
Le liant est constitué soit par l'association d'une gomme polyester et d'une résine polyester, soit par l'association d'une gomme acrylique et d'un plastifiant de cette gomme.
Les solides (A) et les liquides (B) sont introduits dans le mélangeur-extrudeur bi-vis (1) par deux ouvertures d'alimentation différentes. Les constituants sont alors transportés et malaxés dans le compartiment (2) de manière à obtenir une pâte homogène. Cette pâte est ensuite dégazée dans le compartiment (3) puis extrudée sous forme de joncs (8). Ces joncs sont découpés en chargements (9).
