Embodiment 1

[0015] First, weigh 18.2 kg of ammonium nitrate according to the formula, put the ammonium nitrate into a heavy wheel mill at 100 °C after coarse crushing, and roll for 20 minutes. 2:1), and then rolling for 10 minutes, ammonium nitrate fineness 71% passed 60 mesh; then weighed 0.50 kg of wood powder after flue gas drying and crushing; weighed 0.5 kg of composite oil phase melted and kept at 90 to 110 ° C ; Sponge titanium powder: 0.80kg. Next, add modified ammonium nitrate, composite oil phase, wood flour, and titanium sponge to the wheel mill and mix at low temperature. The wheel mill passes cooling water for 30 minutes, and the drug is discharged at 45°C; during this process, the modified ammonium nitrate is added. Roll and mix for 2 minutes, add compound oil and mix for 18 minutes, then add wood flour and titanium sponge powder and mix for 10 minutes. Finally, the mixed product was packaged at 45°C to obtain 20 kg of high-power modified ammonium oil explosive containing s...

Embodiment 2

[0025] First, weigh 17.9 kg of ammonium nitrate according to the formula, put the ammonium nitrate into a heavy weight wheel mill at 105 ° C after coarse crushing, and roll for 25 minutes, then add the modified additive 0.1 kg of octadecylamine and K12. The mixing ratio is 2:1), and then rolling for 12 minutes, ammonium nitrate fineness 75% passed 60 mesh; then weighed 0.6kg of wood powder after flue gas drying and crushing; weighed 0.6kg of composite oil phase melted and kept at 90-110°C ; Sponge titanium powder: 0.90kg. Next, add modified ammonium nitrate, composite oil phase, wood flour, and titanium sponge to the wheel mill for low-temperature mixing, pass cooling water through the wheel mill, mix for 35 minutes, and discharge at 45°C; during this process, add modified ammonium nitrate Grind and mix for 3 minutes, add compound oil and mix for 20 minutes, then add wood flour and titanium sponge powder and mix for 12 minutes. Finally, the mixed product was packaged at 45° C...

Embodiment 3

[0035] First, weigh 18.0 kg of ammonium nitrate according to the formula, put the ammonium nitrate into a heavy wheel mill at 105 ° C after coarse crushing, and roll for 30 minutes, add the mixed modified additive 0.15 kg of octadecylamine and the mixing ratio of K12 is 2:1), and then rolling for 15 minutes, ammonium nitrate fineness 80% passed 60 mesh; then weighed 0.4kg of wood powder after flue gas drying and crushing; weighed 0.6kg of composite oil phase melted and kept at 90-110°C ; Sponge titanium powder: 1.0kg. Next, add modified ammonium nitrate, composite oil phase, wood powder, and titanium sponge to the wheel mill and mix at low temperature. The wheel mill passes cooling water for 40 minutes, and the drug is discharged at 45°C; during this process, the modified ammonium nitrate is added. Grind and mix for 5 minutes, add compound oil and mix for 23 minutes, then add wood flour and titanium sponge powder and mix for 12 minutes. Finally, the mixed product was packaged...

Abstract

The invention belongs to titanium sponge powder-containing high-strength modified ammonium nitrate fuel oil explosive used in engineering blasting and a method for making the same. The ammonium nitrate fuel oil explosive is powdery explosive consisting of powdery ammonium nitrate, wood flour, modified addition agent, a compound oil phase material and titanium sponge powder. The high-strength modified ammonium nitrate fuel oil explosive does not contain high explosives such as TNT, and contains titanium sponge powder; moreover, the explosive has a simple manufacturing method and better explosion properties than ammonium nitrate fuel oil explosive.

Description

technical field [0001] The invention relates to a high-power modified ammonium oil explosive containing sponge titanium powder and a preparation method thereof. Background technique [0002] At present, most of the ammonium ladder explosives produced by domestic manufacturers contain more or less TNT simple explosives. Due to the high risk in the production, transportation and storage of TNT, serious environmental pollution, and great harm to the physical and mental health of operators, it is one of the products restricted in my country; the existing expanded ammonium nitrate powder explosives and modified ammonium oil Although explosives such as dynamites that do not contain high explosives have overcome the above shortcomings, there are shortcomings such as small volume and power, which are limited to a certain extent in popularization and application. Contents of the invention [0003] The purpose of the present invention is to provide a high-power modified ammonium oil...
