ABSTRACT:
Solid water-in-oil emulsion explosive compositions comprising a discontinuous emulsion phase formed of an aqueous solution of an oxidizer salt and a continuous emulsion phase formed of a solid carbonaceous fuel derived from an oleaginous liquid. The continuous phase provides a self-sustaining matrix. A solid non-hygroscopic oxidizer salt, such as ammonium perchlorate, is dispersed in the emulsion in a solid granular form. Void cells are also dispersed within the emulsion to provide a void volume of at least 5%. The explosive compositions may be formulated to be sensitive to No. 8 blasting caps. Processes for forming the explosive compositions include the use of an oleaginous liquid of a polyester and styrene monomer mixture, which is emulsified with an aqueous solution of oxidizer salt without the addition of an emulsifying agent. The explosive composition may be formed as a unitary product or transformed into granular particulate form.
