Ambient temperature mix, cast, and cure composite propellant formulations |
摘要 |
Composite propellant formulations containing a novel combination of bonding agent and cure catalyst together with carefully balanced HTPB binder and isocyanate curative may be mixed, cast, and cured at ambient temperature. The NCO/OH ratio is in the range from about 0.8 to about 0.9. The propellant formulations include as typical solid ingredients an oxidizer such as ammonium perchlorate and a reactive metal fuel such as aluminum. A plasticizer may optionally be included in the propellant to improve processing and low temperature properties. The bonding agents used in the present invention include a Schiff base or a combination of Schiff base and hydroxyl or amine functionality.
