Abstract

Abstract

A new emulsion explosive was obtained by introducing energetic microballoons containing alkane into emulsion matrix. Energetic microballoons were foamed in a constant temperature environment of 90 ℃ for 5 min to reach the maximum volume, and then energetic microballoons were mixed with emulsion matrix to prepare emulsion explosive with the energetic microballoon contents from 0.2% to 7%. The detonation velocity of emulsion explosives with different microballoons was measured by detonation velocity meter. In a steel explosion vessel with a diameter of 5 m and a depth of 5 m, the explosives were placed at a depth of 3 m, which were 0.8, 1.0, 1.2 and 1.4 m away from sensor. The underwater explosion pressure-time curve of emulsion explosive with microballoon contents from 0.2% to 7% was obtained through underwater explosion experiment. The parameters of underwater explosion, such as shock wave peak pressure, specific shock wave energy, specific bubble energy and specific explosion energy, were obtained by analysis and calculation, which was used to explore the influence of energetic microballoon contents on the underwater explosion property of explosive. The results show that the peak pressure of emulsion explosive with microballoon content of 0.2% is the largest and decreases with the increase of microballoon contents at the same testing distance. The specific bubble energy of emulsion explosive increases firstly and then decreases with the increase of the microballoon contents, and the specific bubble energy is the largest when the microballoon content is 4%. The specific shock wave energy and specific explosion energy decrease as microballoon contents increase. The attenuation rate of underwater shock wave peak pressure is negatively correlated with propagation distance. However, the specific shock wave energy, special bubble energy and special explosion energy do not change with the increase of propagation distance.
