Abstract

The invention relates to the technical field of explosive preparation, in particular to an environment-friendly emulsion explosive. The flame retardant comprises the following raw materials in percentage by mass: 40%-43% of ammonium nitrate, 13%-15% of sodium nitrate, 5%-7% of a modified combustible agent, 3%-5% of a flame inhibitor, 2%-4% of a compound emulsifier, 4%-8% of perlite, 1%-3% of a foaming aid, 4%-6% of a hydrolysis-resistant additive and the balance of water. According to the present invention, the detonation velocity, the brisance and the gap distance of the emulsion explosive can be significantly improved, and the hydrolysis resistance of the emulsion explosive in the underwater environment can be further improved.

Description

technical field [0001] The invention relates to the technical field of explosive preparation, in particular to an environment-friendly emulsion explosive. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt aqueous solution evenly 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. [0003] As an explosive, its explosive performance is an important performance index. Moreover, the easily hydrolyzable components such as ammonium nitrate and sodium nitrate contained in the explosive are easy to decompose in a humid environment, so that the use effect of the explosive is reduced. Therefore, we propose an environmentally friendly emulsion explosive to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the pri...
