Abstract

The invention discloses an emulsified explosive with long-term storage stability, belongs to the technical field of explosives, and relates to an emulsified explosive. The problem that an existing emulsified explosive is short in storage period is solved. The emulsified explosive with the long-term storage stability is prepared from, by weight, 72.23 parts of ammonium nitrate, 9.85 parts of sodiumnitrate, 11.71 parts of water, 1.46 parts of paraffin, 1.46 parts of microcrystalline wax, 0.31-0.96 part of base oil, 0.62-1 part of Span-80 and 0.93-2.36 parts of LZ2820. Accordingly, two emulsifiers of Span-80 and LZ2820 are mixed to prepare the emulsion explosive, and the emulsion explosive is high in detonation speed and brisance, better in storage stability and good in water resistance.

Description

technical field [0001] The invention belongs to the technical field of explosives and relates to emulsion explosives, in particular to an emulsion explosive with long-term storage stability. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt solution evenly in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres to form a water-in-oil emulsion-like explosive. , is a new industrial explosive developed in the 1970s. [0003] The stability of emulsion explosives is an important factor affecting the quality of emulsion explosives, and the stability is usually expressed by the length of natural storage period. "General Technical Conditions for Industrial Explosives" (GB28286) stipulates that the guarantee period of rock-type emulsion explosives is 6 months. With the internationalization of trade, some foreign users have higher requirements ...
