EMULSIFIER FOR INDUSTRIAL EMULSION EXPLOSIVES Russian patent published in 2021 - IPC C06B23/00 B01F17/00 

FIELD: blasting.

SUBSTANCE: invention can be used in the production of emulsion-type explosives for blasting. An emulsifier for industrial emulsion explosives contains industrial oil, a gel-forming agent, a foaming agent, a surfactant and a stabilizer. As a gel-forming agent, it contains alkenyl-succinic anhydride, as a foaming agent - methyl cellulose, as a surfactant - PO6RZ, as a stabilizer - glycerin oleate. The composition of the emulsifier has the following ratio of components, wt.%: alkenyl-succinic anhydride 30-35, methyl cellulose 0.5-1.5, PO6RZ 0.7-1.1, glycerin oleate 0.8-1.2, industrial oil is the rest.

EFFECT: invention provides an increase in the viscosity of the emulsion explosive composition after injection into the well and an increase in the life time in the well.
