Abstract

L'invention concerne l'obtention, par coulée, d'un revêtement de polyuréthanne sur une charge de propergol pour en inhiber la combustion périphérique. On obtient le polyuréthanne par la réaction d'un constituant polyéther-polyol aliphatique avec un constituant polyisocyanate aliphatique. Conviennent des polyols ayant 4 à 8 groupes fonctionnels, un poids moléculaire de 400 à 1 000, et un rapport C/O inférieur à 3 (utilisés isolément ou en mélange avec des polyéther-triols ou -diols), et des di- ou tri-isocyanates aliphatiques à rapport C/O inférieur à 5. On peut y ajouter des agents d'allongement et de réticulation des chaînes, ainsi que des charges. Application : durcissement du mélange des constituants 7 moulés autour d'une charge 4 de propergol dans un moule 1, 2, 3, pour réguler la combustion du propergol 4.
