Abstract

The invention discloses a low-density rock expanded AN explosive, which comprises the following raw materials by weight percentage: 90 to 94% of ammonium nitrate, 0.1 to 0.3% of diffusant, 2 to 5% of wood flours, 1 to 2% of perlite, 2 to 5% of oil phase, 0.1 to 0.2% of octadecylamine and 0.1 to 0.2% of eleaostearic acid. The explosive is strong in free-running property, low in density, excellent in explosion performance, simple in preparation process and long in storage period.

Description

technical field [0001] The invention relates to the technical field of explosives and manufacture, in particular to a low-density rock expanded ammonium nitrate explosive and a preparation method. Background technique [0002] Rock-expanded ammonium nitrate explosive is a craft powder explosive that does not contain violent explosives, high-energy substances and other sensitizers. It is prepared by adding composite oil phase and wood powder to expanded ammonium nitrate. Expanded ammonium nitrate is produced in It is prepared by dissolution and vacuum expansion crystallization under the action of surfactant. It is widely used because of its simple operation, relatively loose process conditions, low energy consumption, large production capacity, and stable and reliable product quality. The main problem of the rock-expanded ammonium nitrate explosive in the prior art is that due to the use of a composite oil phase in the preparation process, the viscosity of the explosive is v...
