ROCKET SOLID-PROPELLANT CHARGE Russian patent published in 2009 - IPC F02K9/10 C08L23/16 

Abstract RU 2367812 C1

FIELD: engines and pumps.

SUBSTANCE: invention relates to solid-propellant charges. Proposed charge comprises casing and propellant charge attached thereto by protective-attachment layer. The latter represents a calendered sheet material based on ethylene-propylene and comprising serpentine asbestos as filler, dioctyldecyl adipate as plastifier and n-dinitrosobenzene as adhesive additive. Note here that the surface of aforesaid layer, on boundary of contact with propellant charge, is subjected to modification by thermally-treated 4,4'-diphenyl methane diisocyanate in the amount of 5 to 20 g/m2.

EFFECT: reliable attachment of charge to engine housing that allows charge longer life.
