Embodiment 1

[0020] Example 1, take 1 kg of ammonium nitrate, 0.5 kg of ammonium perchlorate, 1 kg of cerium nitrate, 0.7 kg of thiourea, and 2-3 kg of water, and dissolve them completely at a controlled temperature of 100-120° C. to prepare an aqueous solution. Then take 0.3 kg of PCE, 0.2 kg of Span80, 0.4 kg of engine oil, and 0.3 kg of paraffin, and heat it to 110-120°C to make an oil phase solution. Then add the water phase solution and the oil phase solution into the emulsification tank, and at the same time add 0.15-0.25 kg of emulsifier and mix evenly, and finally emulsify to form a viscous emulsified explosive matrix, and finally add 0.2-0.5 kg to meet different engineering needs sensitizer to obtain high-density and high-energy emulsion explosives.

Embodiment 2

[0021] Embodiment 2, take 1 kilogram of ammonium nitrate, 0.8 kilogram of ammonium perchlorate, 1 kilogram of lead nitrate, 0.5 kilogram of urea, 3-4 kilogram of water, control temperature 110-130 ℃ to dissolve completely, make aqueous phase solution. Then take 0.3 kg of Span80, 0.4 kg of T155, 0.3 kg of engine oil, and 0.4 kg of composite wax, and heat it to 110-120°C to make a uniform oil phase solution. Finally, add the water phase solution and the oil phase solution into the emulsification tank, and at the same time add 0.15-0.25 kg of emulsifier and mix evenly, and finally emulsify to form a viscous emulsion explosive matrix. Finally, add 0.4-0.7 kg to meet different engineering needs Additives to obtain high-density and high-energy emulsion explosives.

Embodiment 3

[0022] Embodiment 3, take 1 kilogram of ammonium nitrate, 0.6 kilogram of ammonium perchlorate, 1 kilogram of barium nitrate, 3-4 kilograms of water, 0.8 kilogram of thiourea, control temperature 110-130 ℃ to dissolve completely, make aqueous phase solution. Then take 0.6 kg of PCE, 0.3 kg of T155, 0.4 kg of waste oil, and 0.4 kg of composite wax, and heat it to 110-120°C to make a uniform oil phase solution. Finally, add the water phase solution and the oil phase solution into the emulsification tank, and at the same time add 0.15-0.25 kg of emulsifier and mix evenly, and finally emulsify to form a viscous emulsion explosive matrix. Finally, add 0.4-0.7 kg to meet different engineering needs Additives to obtain high-density and high-energy emulsion explosives.

Abstract

The invention discloses a high-density high-energy emulsion explosive. The high-density high-energy emulsion explosive is prepared from the following raw materials in parts by weight: 66-85 parts of an aqueous phase, 28-35 parts of an oil phase and 5-10 pars of an additive; the aqueous phase is prepared from the following components in parts by weight: 20-28 parts of ammonium nitrate, 4-8 parts ofperchlorate, 20-28 parts of nitryl metal salt, 3-6 parts of thiourea, and 5-18 parts of water; the oil phase is prepared from the following components in parts by weight: 6-14 parts of PCE, 8-15 parts of Span80 or 6-10 parts of T155, 2-8 parts of illegal cooking oil or 2-8 parts of engine oil, and 2-8 parts of compound wax or 2-8 parts of paraffin. The invention belongs to the technical field ofemulsion explosives. The prepared emulsion explosive has higher density, explosion heat and power, and high energy density, and is capable of satisfying the requirements of medium-length hole blastingexplosion in a strip mine and underwater special blasting engineering better.

Description

technical field [0001] The invention belongs to the technical field of emulsion explosives, in particular to a high-density, high-energy emulsion explosive and a preparation method thereof. Background technique [0002] Emulsion explosives generally refer to a class of water-in-oil emulsion type water-resistant industrial explosives prepared by emulsification technology. Usually, emulsion explosives use fine droplets of oxidant aqueous solution as the dispersed phase, and the suspension contains dispersed bubbles or hollow glass microspheres or other porous materials. A water-in-oil type special emulsification system is formed in the continuous medium composed of oil-like substances of the material, which is a kind of waterproof latex explosive widely used in the field of open-pit mining engineering and underwater blasting engineering. At present, for open-pit mining medium and deep hole blasting projects and underwater blasting reef blasting projects, the density of the emu...
