Embodiment 1

[0010] Example 1: (1) Preparation of expanded ammonium nitrate: Based on the weight of ammonium nitrate, add 8 to 10% of water and 0.10% of surfactant, then heat to 130 to 140°C, at a vacuum degree of -0.090 ~-0.096MPa crystallization, discharge, and produce expanded ammonium nitrate;

[0011] (2), by weight percentage, mix 80-90% expanded ammonium nitrate with 2-12% porous granular ammonium nitrate, 0.2-0.5% calcium fluoride, 3-5% chaff, 23% diesel oil, Mix 0.10-0.12% octadecylamine and 1-2% compound wax for 10 minutes, discharge, and control the temperature at 50-60°C; pack to obtain the finished product.

[0012] The charge density of the invention is 0.99-1.09g / cm3, which increases the volume and power of the explosive, and the explosive power is better than that of the existing expanded ammonium nitrate explosive. At the same time, it has the characteristics of simple process and convenient operation.

Abstract

In the prior art, the expanded ammonium nitrate explosive has disadvantages of low density, small volume power and easy agglomeration. For solving the disadvantages in the prior art, the present invention provides a modified expanded ammonium nitrate explosive with advantages of stable quality, simple production and low cost. The modified expanded ammonium nitrate explosive provided by the present invention has characteristics of good detonation sensitivity, stable detonation velocity, easy charging, no agglomeration, high charge density and large volume power. The technical scheme of the modified expanded ammonium nitrate explosive is that: the modified expanded ammonium nitrate explosive is prepared through mixing the following raw materials, wherein the raw materials comprise, by weight, 80-90% of expanded ammonium nitrate, 3-5% of hull, 2-3% of diesel fuel, 1-2% of % composite wax, 0.10-0.12% of qctadecyl amine, 0.2-0.5% of calcium fluoride and 2-12% of porous granular ammonium nitrate.

Description

technical field [0001] The invention is a modified expanded ammonium nitrate explosive. Background technique [0002] The proportion of the existing expanded ammonium nitrate explosive is: expanded ammonium nitrate is 90-94%, wood flour is 3-5%, diesel oil is 2-3%, and composite wax is 1-2%. It has the following disadvantages: (1), high cost; (2), low charge density (0.8-0.86 g / cm3); (3), small volume and power; (4), the prepared expanded ammonium nitrate explosive is not easy to pack (5) Extensive use of wood powder is not conducive to environmental protection. Contents of the invention [0003] Aiming at the deficiencies of the existing expanded ammonium nitrate explosives such as low density, small volume and power, high cost and easy agglomeration, the present invention proposes a modified expanded ammonium nitrate explosive. It has the characteristics of good detonation sensitivity, stable detonation velocity, easy charge, no caking, high charge density (0.99-1.09 g...
