Abstract

The invention discloses a high-performance mixed-loaded emulsion explosive. The explosive is composed of the following components in parts by mass: 60 to 70 parts of an oxidizing agent, 5 to 7 parts of an oil phase, 10 to 15 parts of water, 5 to 7 parts of aluminum powder, 1 to 3 parts of an emulsifier, 0.5 to 1.2 parts of a sensitizer, 0.02 to 0.05 part of a sensitization accelerator and 1 to 2 parts of a flame inhibitor. The oxidizing agent is composed of the following components by the weight percentage: 35 to 45% of ferric nitrate, 15 to 18% of sodium nitrate, 5 to 7% of zinc nitrate, 7 to9% of calcium nitrate and the balance being ammonium nitrate, wherein the sum of the weight percentages of the components is 100%. The oil phase is composed of the components in parts by mass: 3 to 5parts of engine oil, 1 to 3 parts of diesel oil, 0.5 to 1 part of petroleum calcium sulfonate, 1 to 3 parts of microcrystalline wax, 0.7 to 1.0 part of vegetable pitch and 1 to 2 parts of base oil. The invention further provides a preparation method of the high-performance mixed-loaded emulsion explosive; the preparation method is simple and easy to implement, and the prepared emulsion explosiveis good in stability and low in cost.

Description

technical field [0001] The invention relates to an explosive, in particular to a high-performance mixed emulsified explosive and a preparation method. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt solution evenly 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-like explosive. , is a new type of industrial explosive developed in the 1970s, mixed emulsion explosive is a kind of emulsion explosive; [0003] Due to its low cost, safety and high efficiency, mixed emulsion explosives have been popularized and adapted in many large mines. According to different charging environments, bulk explosive mixing vehicles and charging devices for open-air and underground mine blasting sites have been launched. However, on-site mixed emulsion explosives have low viscosity and short storage period, and the s...
