Abstract

The invention relates to a preparation technology of a water-resisting modified ammonium nitrate fuel oil (ANFO) explosive, and provides a preparation technology of a non-TNT high-performance powdery ANFO explosive with high physical and chemical properties of functional powder. According to the invention, a mechanical force chemical modification technological mode is adopted. Good water resistance is provided for the explosive through the addition of a water-resisting composite oil phase rich in hydrophobic factors. The density of the explosive is reasonably regulated through the addition ofa density regulator. Therefore, good detonation sensitivity and detonating transfer performance are provided for the explosive. Compared to prior arts, the water-resisting modified ANFO explosive prepared with the technology provided by the invention is characterized by reasonable and advanced formulation. The explosive is safe and reliable, and has good damp proofing, agglomeration resisting, water resisting, and explosion performances. Therefore, the explosive is suitable for industrialized productions.

Description

technical field

[0001] The invention relates to a modified ammonium oil explosive used in blasting engineering and a preparation method thereof, in particular to a water-resistant modified ammonium oil explosive and a preparation method thereof. Background technique

[0002] Powdered ammonium nitrate explosives mainly include ammonium oil explosives and ammonium ladder explosives. Ammonium oil explosives are usually mixed with ammonium nitrate and diesel oil, while ammonium ladder explosives contain 10-20% TNT as a sensitizer, and their explosive performance is significantly better than that of ammonium oil explosives. However, TNT is poisonous, polluting, and costly. Production safety; ammonium oil explosives have low cost and simple production process, but have a series of defects such as low detonation sensitivity, poor explosive performance, easy oil leakage and deterioration, and unfavorable storage. At the same time, the two types of explosives are easy to absorb and ...
