FIELD: explosive substances.
SUBSTANCE: invention relates to emulsion explosive substances. Invention proposes a method for modifying the brisance of emulsion explosive substance prepared by using emulsion of type "water-in-oil" (reverse emulsion) containing oily phase and dispersed phase consisting of inorganic nitrates and/or perchlorates an aqueous solution that can comprise also inorganic or organic components and involving addition the brisance modifying agent to the oily phase. Prepolymer or polymer with links -[CH2-C(X)=CH-CH2]- as the brisance modifying agent wherein X means hydrogen atom (-H) or methyl group (-CH3) in macromolecule terminating by hydroxyl or isocyanate groups or polyisobutylene groups. The dispersed phase of emulsion explosive substance can comprise a cooling component in form of inorganic chloride group. Invention is directed for reducing the brisance of emulsion explosive substance with retaining its working properties.
EFFECT: improved and valuable properties of explosive substance.
