Abstract

DANS UNE APPLICATION PREFEREE, LA PAROI 10 D'UNE CHAMBRE EST REVETUE D'UNE COUCHE 11 DE MATERIAU ISOLANT PUIS D'UNE COUCHE 12 DE REVETEMENT INTERIEUR. LE REVETEMENT 12 CONTIENT UN COMPOSE D'ISOCYANATE SOLIDE 24 DISPERSE DANS UN POLYURETHANE A BASE D'UN COMPOSE ORGANIQUE HYDROXYLE. LA COMPOSITION PEUT ETRE TOTALEMENT DURCIE ET FOURNIT CEPENDANT UN EXCES DE GROUPEMENTS ISOCYANATE QUI PEUVENT REAGIR AVEC DES GROUPEMENTS HYDROXYLES CONTENUS DANS UNE COUCHE ADJACENTE 14 EN FORMANT DES LIAISONS 28 A L'INTERFACE 18 ENTRE LE REVETEMENT 12 ET LA CHARGE 14. APPLICATION A LA PREPARATION DE CHAMBRES DE MOTEURS-FUSEES CONTENANT UN PROPERGOL SOLIDE.IN A PREFERRED APPLICATION, THE WALL 10 OF A BEDROOM IS COATED WITH A LAYER 11 OF INSULATION MATERIAL THEN WITH A LAYER 12 OF INTERIOR COATING. THE COATING 12 CONTAINS A SOLID ISOCYANATE COMPOUND 24 DISPERSE IN A POLYURETHANE BASED ON AN ORGANIC HYDROXYL COMPOUND. THE COMPOSITION CAN BE TOTALLY CURED AND HOWEVER PROVIDES AN EXCESS OF ISOCYANATE GROUPS WHICH MAY REACT WITH HYDROXYL GROUPS CONTAINED IN AN ADJACENT LAYER 14 FORMING BONDS 28 AT INTERFACE 18 BETWEEN COATING 12 AND PREPARATION 14. APPLICATION TO THE COATING 12 AND PREPARATION 14. OF ROCKET ENGINE CHAMBERS CONTAINING A SOLID PROPERGOL.
