Intumescent polymer compositions for rockets
Abstract
Abstract THIS INVENTION PERTAINS TO CHEMICAL COMPOSITIONS USEFUL IN THERMAL BARRIERS OF A SOLID-PROPELLED ROCKET MOTOR WHICH PROVIDES ZONING CAPABILITY FOR A MISSILE. FLAME RESISTANT CHEMICAL COMPOSITIONS WHICH INTUMESCE ARE EMPLOYED IN THE INERT ELASTOMERIC BARRIER THAT IS EMBEDDED BETWEEN LAYERS OF SOLID PROPELLANT. DISCLOSED ARE INTUMESCENT CHEMICAL COMPOSITIONS USEFUL AS THERMAL BARRIERS AND ADDITIVES TO ROCKET MOTOR CASE INSULATION AND LINER MATERIALS. THE DISCLOSED TYPICAL INTUMESCENT COMPOSITIONS ARE COMPRISED OF AMMONIUM DIHYDROGEN PHOSPHATE, BORIC ACID, A FILLER MATERIAL SELECTED FROM ASBESTOS OR STARCH AND TRAGACANTH, A TITANIUM OXIDE COMPOSITION SELECTED FROM TITANIUM DIOXIDE AND TITANIUM DIOXIDE-BARIUM SULFATE, AND A RESIN.
