EMULSIFYING COMPOSITION FOR PRODUCTION OF THE EMULSION BLASTING EXPLOSIVES AND THE METHOD OF ITS PRODUCTION Russian patent published in 2006 - IPC B01F17/34 B01F17/16 C06B23/00 

FIELD: chemical industry; methods of production of emulsifying composition for production of emulsion blasting explosives.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to production of emulsifying compositions applied in production of blasting explosives of the emulsion type for the mountain boulder blasting. The emulsifying structure includes the products of condensation poly isobutylene succinic anhydrides with alkanolamines in the form of the solution in the industrial oil. The composition contains the mixture of the products of condensation of poly isobutylene succinic anhydrides with monoethanolamine and triethanolamine in the following ratio in the initial reaction mass: monoethanolamine - from 0.2 up to 0.5 mole and triethanolamine - from 1.5 up to 1.8 mole per 1 mole of polyisobutylene succinic anhydride. In the method of production of the composition the process of condensation of polyisobutylene succinic anhydride conduct with sequential addition of 0.2-0.5 mole of monoethanolamine, then - 1.8-1.5 mole of triethanolamine per 1 mole of poly isobutylene succinic anhydride with intermixing at the stirrer rotation rate of 2.5 3.6 m\s. To decrease the frothing effect introduce 0.005-0.01 mass % of polymethylsiloxyne liquid. The technical result of the invention is - rising of technological effectiveness of the emulsifying composition by optimization of the average molecular mass of the emulsifier.

EFFECT: the invention ensures the rise of the technological effectiveness of the emulsifying composition due to optimization of the average molecular mass of the emulsifier.
