WATER-RESISTANT EMULSION EXPLOSIVE AND EMULSION COMPOSITION FOR WATER-RESISTANT EXPLOSIVES Russian patent published in 2015 - IPC C06B31/28 C06B47/14 

FIELD: chemistry.

SUBSTANCE: invention relates to production of safe water-resistant emulsion explosives. The water-resistant emulsion explosive contains, wt %: oil-in-water emulsion 80.00-30.00, ammonia nitrate 18.60-65.70, gas-generating agent in the form of a gasification solution 0.20-0.10 and petroleum products 1.20-4.20. The petroleum products used are diesel fuel; the oil-in-water emulsion is based on aqueous ammonium or sodium nitrate and includes 70% acetic acid, thiourea as a catalyst and 40% sodium hydroxide. The emulsion explosive includes granular ammonium nitrate which is mechanically mixed with said emulsion.

EFFECT: invention is aimed at improving stability of operational and explosive properties and improving effectiveness of the explosive effect.
