Abstract

The invention discloses a modified ammonium nitrate-fuel oil explosive, which is composed of the following components in percentage by weight: 90.6 to 95% of ammonium nitrate, 2 to 4% of high performance composite oil phase, 3 to 5% of wood powder, and 0.2 to 0.4% of high performance ammonium nitrate modifier; wherein the high performance composite oil phase is composed of the following components in percentage by weight: 0.5 to 2% of composite surfactant, 5 to 30% of stearic acid, and 68 to 94.5% of composite oil phase; the composite surfactant is composed of 40 to 70% of gemini surfactant, 20 to 40% of fatty alcohol-polyoxyethylene ether, and 0 to 20% of octyl phenol-polyoxyethylene ether; and the high performance ammonium nitrate modifier is composed of 10 to 30% of gemini surfactant, 10 to 20% of sodium cetyl sulfonate, 10 to 30% of octadecyl amine, 20 to 30% of sodium stearate, and 10 to 20% of dispersant. The formula is reasonable, the adaptability is strong, the conventional technology is not changed, the explosive is safe and reliable, the storage period is prolonged, and the explosive performance is enhanced.

Description

technical field [0001] The invention relates to a modified ammonium oil explosive and belongs to the field of industrial explosive manufacturing. Background technique [0002] Among powdery industrial explosives, ammonium ladder explosives were originally a very important one. Because the ammonium ladder explosive uses TNT as a sensitizer, it has the advantages of simple composition, convenient processing, and good explosive power, and its explosive performance is also much better than that of ammonium oil explosives. However, TNT has strong toxicity, poor safety, serious environmental pollution, and great harm to human health. It is strictly prohibited to use in the production of civilian explosives. At present, powdery explosives mainly include expanded ammonium nitrate explosives, powdery emulsion explosives, and modified ammonium oil explosives. Expanded ammonium nitrate explosive is high-temperature and high-concentration ammonium nitrate aqueous solution under the ac...
