Abstract
The present invention relates to a high energy-containing propellant composition and a use thereof. The propellant composition of the present invention is a propellant composition for guns, including: (a) 55 to 85 wt % of a nitrocellulose binder; (b) 10 to 35 wt % of a nitramine oxidant; (c) 1 to 4 wt % of a plasticizer having both a nitrate group and a nitramine group; and (d) 0.5 to 3 wt % of a stabilizer. The propellant composition of the present invention significantly improves a physical compatibility between the nitrocellulose binder and the oxidant using a plasticizer containing both a nitrate group and a nitramine group, leading to stable interior ballistics characteristics from low temperature to high temperature as well as improvement on the characteristics of an extrudate. Accordingly, the propellant composition of the present invention may be effectively applied to an ammunition for guns due to an excellent physical property and interior ballistic stability thereof.
