Problems solved by technology

This method has the cheapest cost and the simplest process, but has short storage performance and is not suitable for production in specialized factories.
Physical sensitization mostly uses hollow resin microspheres, hollow glass microspheres, and expanded perlite as carriers, and introduces air bubbles into the emulsified matrix to achieve the purpose of sensitization. This method is relatively simple to operate and has relatively stable performance, but the manufacturing cost is relatively high.
Chemical sensitization generally uses nitrite, bicarbonate, organic azo compounds, and nitroso compounds as gas-generating agents to generate gas through chemical reactions and introduce the gas into the emulsified matrix to achieve the purpose of sensitization. The process of this method is relatively complicated. But the cost is low, and the performance of the produced emulsion explosive is relatively high

Abstract

The invention discloses novel sensitization bubble carrier colloidal emulsion explosive. The colloidal emulsion explosive comprises the following components: inorganic oxidizer salt, water, a compound oil phase, an emulgator, a compound flame inhibitor, a sensitizer, a foaming agent and a foaming accelerant, wherein the inorganic oxidizer salt is a mixture of ammonium nitrate, sodium nitrate and urea. The invention also designs a preparation method of the novel sensitization bubble carrier colloidal emulsion explosive. The preparation method comprises the following steps: firstly preparing a water phase, adding an oil phase to the water phase for mixing, then sequentially emulsifying and sensitizing, and finally filling to obtain a finished product. The novel sensitization bubble carrier colloidal emulsion explosive is good in water resistance, excellent in explosive performance, proper in sensitivity, suitable for blasting of various environments, simple and convenient in production process, low in affect on environment and low in cost.

Description

technical field [0001] The invention belongs to the field of explosive preparation, and in particular relates to a novel sensitized bubble carrier colloidal emulsion explosive and a preparation method thereof. Background technique [0002] Emulsion explosives are prepared by emulsification technology. The droplets of oxidant salt aqueous solution are uniformly dispersed in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres to form a water-in-oil emulsion. explosives. Emulsion explosives have excellent blasting performance and water resistance, are non-toxic and pollution-free during production, and are relatively safe during transportation, storage, and use. It is convenient to deliver and has become a key development product in my country's civil explosive equipment industry. [0003] With the development of continuous automation technology for emulsion explosive production lines in my country, the produc...
