Abstract
This invention relates to water-in-oil emulsion explosives in which an oxidizing material is contained in the discontinuous water phase, and the continuous oil phase acts as a carbonaceous fuel. More particularly, this invention relates to such explosives in which polyfunctional carboxylic acids, sulfonic acids, or phosphorous-containing acids, soluble in the oil phase, are caused to cross-link using an inorganic cross-linker, thereby causing the viscosity of the emulsion to increase.
Claims31
An explosive emulsion comprising:
- (A) a discontinuous aqueous oxidizer phase comprising at least one oxygen-containing component, (B) a continuous organic phase which comprises at least one carbonaceous fuel, (C) an emulsifying amount of an emulsifier suitable for forming a water-in-oil emulsion, (D) an oil-soluble polyfunctional acidic material suitable for cross-linking, and (E) a suitable polyvalent inorganic cross-linking agent, provided that the emulsifier, component (C), may serve as the poly-functional acid suitable for cross-linking.
