  • Ammonium nitrate propellants
    Patent number: 5583315
    Abstract: A propellant with a long shelf life that is smoke-free when combusted. The propellant may have the following composition when the propellant includes a reinforcing agent.______________________________________ Approximate Percentage Material Range by Weight ______________________________________ Ammonium nitrate 40-85 Binder (with curvative) 4-40 Energetic plasticizer 0-40 Reinforcing agent 0.1-8 ______________________________________When the reinforcing agent is included in the propellant, a desiccant in the range of 0.02-6% may or may not be included in the propellant. The binder is selected from the group consisting of a thermoplastic material such as Finaprene.RTM. or Kraton.RTM. (e.g. thermoplastic elastomers) or a cure-hardening material or a combination thereof. Examples of the energetic plasticizer are trimethylolethane trinitrate, triethyleneglycol dinitrate, and butanetriol trinitrate.
