POLYMER COMPOSITION FOR BONDING ARMOURED SOLID PROPELLANT CHARGE WITH GAS GENERATOR HOUSING Russian patent published in 2013 - IPC C09J109/00 C06D5/00 C06B21/00 

FIELD: chemistry.

SUBSTANCE: invention relates to rocket engineering and preparation of a boding polymer composition for bonding an armoured solid propellant charge with a gas generator housing, which prevents longitudinal movement of the charge in the gas generator housing. The polymer composition contains hydroxyl-containing polybutadiene rubber SKD-GTRA, 1,4-butanediol, technical carbon, hexamethylene diisocyanate, dibutyltin dilurate and further contains a combination of N,N,N',N'-tetrakis-(-2-hydroxypropyl-)-ethylenediamine (lapromol 294) and a polyether with molecular weight of 1000 (laprol 1052).

EFFECT: obtaining a polymer composition with low initial viscosity, long life during processing and curing at normal ambient temperature while providing high physical and mechanical properties; disclosed bonding polymer composition is capable of providing high operational reliability of the solid propellant charge in a wide operating temperature range for a long guaranteed shelf life.
