Abstract

The invention discloses an emulsion explosive with long-term storage stability and a preparation method thereof. The emulsion explosive is prepared from the following raw materials in parts by weight:70 to 80 parts of ammonium nitrate, 5 to 15 parts of sodium nitrate, 5 to 15 parts of water, 0.1 to 0.5 part of dioctadecyl dimethyl ammonium chloride, 0.1 to 0.5 part of dodecyl hydroxypropyl phosphate betaine, 0.5 to 1.5 parts of Span-80, 3 to 7 parts of a composite oil phase, 0.1 to 0.3 part of a composite sensitizer and 0.1 to 0.3 part of an accelerant. Through the synergistic effect of the components, the long-term storage stability of the emulsion explosive is remarkably improved, and the emulsion explosive still has a good explosion effect after being stored for about 11 months.
