Problems solved by technology

Since the oxidant phase of this type of explosive contains (8-15)% of water, the working ability of this type of explosive is relatively small
And emulsion explosives are usually colloidal, which is not convenient for storage and use
Chinese patent ZL93117971.8 proposes a powdery emulsion explosive and a preparation method thereof. In this method, the water phase and the oil phase are first made into latex, and then the latex is made into a powdery emulsion explosive by means of rotary flash evaporation, but due to technical Defects on the failure to put into practice
This repeated transportation causes a lot of waste of manpower and material resources, increases production costs, and also brings potential safety hazards.

Embodiment 1

[0010] Embodiment 1 (taking the preparation of 500 kilograms of rock powdery emulsion explosives as an example). The mass percentages of each component of the rock powdery emulsion explosive are selected as follows: 90% ammonium nitrate, 1% urea, 3% water, 1.2% paraffin, 1.2% microcrystalline wax, 1.6% rosin, and 2.0% polymer emulsifier. Accurately weigh 450 kg of ammonium nitrate, 5 kg of urea, 15 kg of water, 6 kg of paraffin, 6 kg of microcrystalline wax, 8 kg of rosin, and 10 kg of polymer emulsifier according to the above proportioning ratio.

[0011] Operation steps: in the first step, heat and dissolve ammonium nitrate, urea and water and raise the temperature to 135°C; Phase and oil phase materials are emulsified into latex through an emulsifier; in the fourth step, the latex obtained in the third step is molded by cold air through a three-fluid nozzle, and the rock powdery emulsion explosive is directly produced. In the fifth step, the rock powdery emulsion explosive...

Embodiment 2

[0012] Embodiment 2 (taking the preparation of 500 kilograms of powdery emulsion explosives as an example). The mass percent of each component of rock powdery emulsion explosive is selected as follows: 89 ammonium nitrate, 2 urea, 3 water, 2.0 paraffin, 1.0 microcrystalline wax, 0.6 rosin, and 2.4 polymer emulsifier. Accurately weigh 445 kg of ammonium nitrate, 10 kg of urea, 15 kg of water, 10 kg of paraffin, 5 kg of microcrystalline wax, 3 kg of rosin, and 12 kg of polymer emulsifier according to the above proportioning ratio. The operating steps and test conditions are the same as in Example 1. The measured explosive performance is: detonation velocity 4650m / s, brute force 18mm, working capacity 332ml, and detonation distance 17cm.

Embodiment 3

[0013] Embodiment 3 (taking the preparation of 500 kilograms of powdery emulsion explosives as an example). The mass percent of each component of the rock powder emulsion explosive is: ammonium nitrate 88, urea 3, water 3, paraffin 1.6, microcrystalline wax 1.2, rosin 1.0, polyethylene 0.4, polymer emulsifier 1.8. Accurately weigh 440 kg of ammonium nitrate, 15 kg of urea, 15 kg of water, 8 kg of paraffin, 6 kg of microcrystalline wax, 5 kg of rosin, 2 kg of polyethylene, and 12 kg of polymer emulsifier according to the above proportioning ratio. The operating steps and test conditions are the same as in Example 1. The measured explosive performance is: detonation velocity 4400m / s, brute force 16mm, working capacity 345ml, and detonation distance 17cm.

Abstract

The invention relates to a rock powder shaped emulsion explosive and manufacturing method thereof, wherein the explosive comprises (by wt. portions) ammonium nitrate 87-93, assisting solvent 1-3, organic oily phase material 4-6, macromolecular emulsifying agent 1-3, and water 1-5. The preparation process comprises the steps of, charging aqueous phase into agitated oily phase, emulsifying into water-in-oil type emulsion, and making emulsion rock powdery explosive through cold air blast modeling.

Description

1. Technical field [0001] The invention relates to an explosive and a manufacturing method thereof, in particular to a rock powder emulsion explosive and a manufacturing method thereof. 2. Background technology [0002] A common emulsion explosive is a water-in-oil emulsion in which the oxidant phase is the dispersed phase and the organic fuel is the continuous phase. Because the oxidant phase of this type of explosive contains (8-15)% of water, the working ability of this type of explosive is relatively small. Moreover, emulsion explosives are usually in a colloidal state, which is inconvenient for storage and use. Chinese patent ZL93117971.8 proposes a powdery emulsion explosive and a preparation method thereof. In this method, the water phase and the oil phase are first made into latex, and then the latex is made into a powdery emulsion explosive by means of rotary flash evaporation, but due to technical The above flaws have not been put into practice. Chinese patent Z...
