Abstract
The invention relates to a single-base granular-energetic colloidal explosive. The single-base granular-energetic colloidal explosive is characterized by being prepared from the following ingredients in percentage by weight: 40-70% of ex-service single-base granular propellant powder, 10-30% of ammonium nitrate, 5-20% of sodium nitrate, 0.1-3.0% of sesbania, 0.01-0.3% of urotropine, 0.01-0.30% of antimony potassium tartrate, 0.01-0.30% of potassium pyroantimonate and 10-20% of water. A method for preparing the single-base granular-energetic colloidal explosive comprises the steps of: preparing an aqueous oxidant solution; preparing a colloidal oxidant solution; and weighing mixed propellant powder, adding the weighed mixed propellant powder into the prepared colloidal oxidant solution and stirring, charging after a mixture is uniform, packaging and gelling, thereby preparing the single-base granular-energetic colloidal explosive. The single-base granular-energetic colloidal explosive is novel, has the aim of recycling ex-service single-base granular propellant powder, and has the advantages of high explosive power, strong water resistance, high density, easiness in charging, no crystal precipitation, safe production process and high ex-service propellant powder handling capacity.
Description
technical field [0001] The invention relates to the technical field of reapplication of decommissioned propellants. In particular, it relates to a civil energetic colloidal explosive manufactured by using decommissioned single-base granular propellant. Background technique [0002] At present, the application of decommissioned propellants in the field of civilian explosives is still in the research stage of single-base propellants with relatively low energy. It exists in explosives; the second is to pour oxidized glue directly into the granular propellant to make perfusion explosives, and the propellant exists in the explosive in the form of particles. There are certain disadvantages in these two application forms. The first one is the safe crushing of propellants. Due to the large number of crushing times, the risk is high, the yield of products is low, and the pollution of crushing cooling water and other issues restrict the development of this technology. developmen...
