Problems solved by technology

Emulsion explosives have been widely used in various civil blasting projects, and show their superiority in water and wet blasting occasions, but their storage stability and quality stability are still poor, and further research and improvement are needed.
[0003] The current emulsion explosives are widely used, and they are relatively mature in waterproof and moisture-proof aspects, but their storage stability and quality stability are poor, and there is a greater safety hazard for the storage of emulsion explosives during use.
[0004] In the process of explosive preparation, poor temperature control ability is easy to cause danger; high power in the sensitization process wastes energy; poor control of emulsification time in the emulsification process makes the quality of the prepared emulsion explosive poor

Abstract

The invention belongs to the field of explosive preparation, and discloses a three-raw-material emulsified explosive as well as a preparation method thereof. A formula of the three-raw-material emulsified explosive comprises a discontinuous phase of oxidized release salt and water and a continuous phase adopting organic fuel oil as an emulsifier. The preparation method comprises the following steps: mixing ammonium nitrate and water, placing a mixture into a closed container, and keeping the temperature of the solution at 90 to 100 DEG C; heating the an emulsifier in the closed container, slowly emulsifying the solution and the emulsifier in an emulsification device,and to obtaining an emulsified matrix; and dissolving a given amount of sodium nitrite and phosphoric acid in the water at 30DEG C, slowly adding the mixed solution into the closed container, sensitizing, and thus obtaining the emulsified explosive. The prepared emulsified explosive is packaged in a packaging machine to form a commodity emulsified explosive, and the emulsified explosive is cooled in an immersion manner by virtue of a water channel and storedstoring is performed. All used raw materials used in the invention are easy to buy, the stability of the explosive can be improved, and the safety potential hazard of the explosive storage can be reduced.

Description

technical field [0001] The invention belongs to the technical field of explosive preparation, and in particular relates to a three-material emulsion explosive and a preparation method thereof. Background technique [0002] Emulsion explosives use the action of emulsifiers to evenly disperse the droplets of oxidant salt aqueous solution in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil emulsion-like explosive. There are many types of emulsion explosives developed at present, including open-pit emulsion explosives for open-pit mines, rock-type emulsion explosives for medium-hard rock blasting, permitted emulsion explosives for underground coal mines, and smooth surface blasting. Emulsion explosive with small diameter and low detonation velocity. Emulsion explosives have been widely used in various civil blasting projects, and show their superiority in water and wet blasting occasi...
