High-free-dispersion antistatic shellac granulation detonator explosive and preparation method of high-free-dispersion antistatic shellac granulation detonator explosive

The invention provides a high-fluidity antistatic shellac granulation detonator explosive. The high-fluidity antistatic shellac granulation detonator explosive is prepared from the following raw materials in parts by weight: 50 parts of hexogen; 50 to 175 parts of water; 0.05 to 0.10 part of a composite surfactant; 0.5 to 1.0 part of shellac; 2.5 to 11.5 parts of ethanol; 0.005 to 0.025 part of colloidal graphite powder; the composite surfactant comprises gelatin and a soap active agent; the mass ratio of the gelatin to the soap active agent is 1: (4.5-5.5). The colloidal graphite powder is used as the antistatic agent, so that on one hand, the electrostatic sensitivity of the lac granulation detonator explosive can be further eliminated, and on the other hand, the free-running property of the lac granulation detonator explosive can be greatly improved. Meanwhile, by optimizing the addition amount of the raw materials, the finally prepared shellac granulation detonator explosive has high free-running property
