METHOD OF PREPARATION OF AN EMULSIFYING AGENT FOR PRODUCTION OF BLASTING EXPLOSIVES AND THE EMULSIFYING AGENT FOR PRODUCTION OF A BLASTING EXPLOSIVE

摘要

FIELD: preparation of emulsifying agents for production of the emulsion blasting explosives applied at a boulder blasting for boreholes drilling.;SUBSTANCE: the invention is pertaining to the field of mining, in particular, to the method of preparation of an emulsifying agent for production of emulsion blasting explosives applied at a boulder blasting for boreholes drilling. The method is realized by mixing of a polyisobutylenesuccinate or polyisobutylenebissuccinate anhydrate with a product of its interaction with an organic monoamine or polyamine. At that in the produced mixture at temperature of 70-150°C and constant stirring action add ethers of fatty acids with polyhydric alcohols. Then at temperature of 20-150°C add alkylbenzosulfonates of Ca, To, Mg, Mo or their mixtures in the form of a 20-70 % solution in the industrial oil. The mixture is agitated at the temperature of 100-150°C and filtered at the temperature of 100-150°C. The emulsifying agent contains the above indicated components at the following ratio (in mass %): polyisobutylenesuccinate or polyisobutylenebissuccinate anhydrate 1-10; the product of interaction of polyisobutylenesuccinate or polyisobutylenebissuccinate anhydrate with the organic monoamine or polyamine 40-90; ethers of fatty acids with polyhydric alcohols 2-30; alkylbenzosulfonates of Ca, To, Mg, Mo or their mixtures 6-30. The technical result is an increased activity of the emulsifying agent, which allows to reduce its concentration in the emulsion of the blasting explosive and to increase duration of stability of the emulsion.;EFFECT: the invention allows to increase activity of the emulsifying agent, to reduce its concentration in the emulsion of the blasting explosive, to increase duration of stability of the emulsion.;2 cl, 2 ex, 1 tbl
