Abstract
The present invention relates to an improved explosive composition. More particularly, the invention relates to a water-in-oil emulsion explosive that is sensitized by chemically formed gas bubbles. The water-in-oil emulsion explosives of this invention contain a water-immiscible organic fuel as the continuous phase, an emulsified inorganic oxidizer salt solution as the discontinuous phase, an emulsifier, a chemical gassing agent and a surfactant for increasing the rate of gas generation from the gassing agent. The invention also relates to a method of forming such explosives. As used herein, the term 'water-in-oil' will refer to a discontinuous phase of polar or water-miscible droplets emulsified throughout a nonpolar or water-immiscible continuous phase. Such emulsions may or may not actually contain water, and those not containing water sometimes are referred to as 'melt-in-oil' emulsions.
