The invention relates to an
emulsion explosive and a preparation method thereof, and belongs to the technical field of
emulsion explosives. The invention aims to provide a high-performance
emulsion explosive. The explosive is prepared from the following components in parts by weight: 92.8-93.8 parts of a water-phase material, 6.2-7.2 parts of an oil-phase material and 0.3-0.45 part of a
foaming agent, wherein the water-phase material comprises the following components in parts by weight: 75-84 parts of
ammonium nitrate, 2-5 parts of
sodium nitrate, 6-11 parts of
titanium black, 0.8-1.2 parts of a surfactant and 9-12 parts of water; and the oil-phase material comprises the following components in parts by weight: 8-12 parts of composite
wax, 8-12 parts of refined paraffin, 15-25 parts of
microcrystalline wax, 15-25 parts of engine oil, 20-30 parts of an S-80 emulsifier, 8-15 parts of an LR-1 emulsifier and 2-6 parts of
titanium sub-
oxide. The explosive is large in
explosive power, the explosive speed is larger than or equal to 5000 m / s, the
explosive power is larger than or equal to 350 mlm / s, the
brisance is 17 mm or above, the product quality is stable, the validity period reaches6 months or above, the blasting effect is good, aluminum
powder does not need to be added into the explosive, and the production process is simple and safe.
