MIXTURE OF HYDROCARBONS FOR PRODUCTION OF EMULSION EXPLOSIVE COMPOSITIONS AND EMULSION EXPLOSIVE COMPOSITION BASED THEREON (VERSIONS) Russian patent published in 2016 - IPC C06B31/32 C06B45/14 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a mixture of hydrocarbons for emulsion explosive compositions (EEC) and to emulsion explosive compositions obtained based thereon. Combustible mixture of hydrocarbons includes, wt%: surfactant - polyisobutylene succinic anhydride with alkanolamine or mixture thereof 22-33, polymer stabiliser - polyisobutylene isomers 10-30, additional stabiliser mixture - fusible hydrocarbon in form of petrolatum with drop point of 48 °C or 72 °C 16-20 and liquid fuel - industrial oil - balance up to 100. Four versions of emulsion compositions are prepared based on said mixture of hydrocarbons with four types of sensitising agents: aqueous solution of sodium nitrite, glass microspheres, polymer microspheres and polymer microspheres in form of foamed polystyrene.

EFFECT: obtained compositions retain stable physical and chemical and explosive characteristics at storage life of not less than 6 months and processing temperature not higher than 85 °C.
