Smokeless Propellant composition containing Bismuth-based compound and method of preparing the same

摘要

The present invention relates to a lead-free high-energy solid propellant composition exhibiting a low pressure index including a bismuth compound as a combustion property improver and a method for producing the same. Since the propellant composition according to the present invention contains a bismuth compound, it is possible to secure the processability of the propellant, especially the castable time. Therefore, unlike the method of introducing the temperature control and curing inhibiting catalyst, To improve reliability of the propellant manufacturing process. It also has the advantage of exhibiting a low pressure index.
