High-energy ignition agent and preparation method thereof

The invention discloses a high-energy ignition agent and a preparation method thereof. The high-energy ignition agent comprises, by weight, 20-25 parts of magnesium powder, 40-50 parts of barium nitrate powder, 20-25 parts of barium peroxide powder, 3-5 parts of shell-lac, 1-2 parts of drying oil and anhydrous ethanol. A volume-mass ratio of anhydrous ethanol to shell-lac is in a range of 2.5-5.5ml/g. The high-energy ignition agent has low mechanical sensitivity, can be stored and transported easily and has a low ignition point, a strong ignition capability and a high self-combustion temperature.
