Problems solved by technology

It is understood that in order to prolong the storage period of emulsion explosives, domestic and foreign manufacturers increase the content of the oil phase and add a large amount of sodium nitrate to reduce the crystallization point to prolong the storage period, but the disadvantage of this method is that the cost increases greatly

Embodiment 1

[0009] Add 8 kg of tap water into the water phase dissolution tank with a power of 3KW and a speed of 1420 rpm, then add 80 kg of ammonium nitrate, 3.5 kg of sodium nitrate, and 1 kg of urea to dissolve under heating. The time is 60 minutes; 2.0 kg of modified Span-80 emulsifier, 1.7 kg of industrial paraffin, and 1.7 kg of industrial vaseline are sequentially added to the oil phase dissolution tank (1.5KW, 1430 rpm) to heat up, and the dissolution temperature is 80°C , the dissolution time is 80 minutes, and it is kept warm for later use. The modified Span-80 emulsifier is a compound of 0.8 kg of soybean flour emulsifier and 1.2 kg of Span-80 emulsifier; after the above-mentioned water phase and oil phase materials are filtered, the water phase The conveying equipment and the oil phase conveying system are sent to the emulsifier for emulsification, with a power of 18.5KW and a speed of 470 rpm, and then sent to the cooling machine (power of 4KW, speed of 40 rev / min) to automa...

Embodiment 2

[0014] Add 11 kg of tap water to the water phase dissolving tank, then add 85 kg of ammonium nitrate, 0.5 kg of sodium nitrate, and 0.3 kg of urea to dissolve under heating. Xingspan-80 emulsifier, 0.15 kg of industrial paraffin, and 0.15 kg of industrial vaseline are added to the oil phase dissolving tank in turn to raise the temperature, the dissolution temperature is 98°C, and the dissolution time is 60 minutes. It is the compound of 0.18 kg of soybean flour emulsifier and 0.12 kg of Pan-80 emulsifier; after the above-mentioned water phase and oil phase materials are filtered, the water phase conveying equipment and oil phase conveying system are sent to the emulsifier for emulsification, and then emulsified with latex The delivery pump is sent to the cooling machine for automatic cooling. The temperature drops below 65°C. After cooling, it will automatically pass through the foaming delivery system and add 2.6 kg of emulsified foaming agent. The emulsified foaming agent is ...

Abstract

The invention provides an emulsified explosive and method for preparing same, wherein the explosive comprises (by weight percentage) 75-85% of ammonium nitrate, 8-14% of water, 0.3-3.5% of nitrates, 0.3-2.0% of urea, 0.3-3.5% of modified emulsifying agent, 0.3-3.5% of compound oil phase, and 0.3-3.5% of emulsion foaming agent. The preparation process comprises the steps of, (1) charging water into ammonium nitrate, heating, agitating, dissolving, charging nitrates, urea, agitating, dissolving, thermal insulating 60-80 minutes, obtaining aqueous phase, (2) mixing modified emulsifying agent, mineral wax and Vaseline, elevating the temperature to 80-98 deg. C, dissolving 60-80 minutes, obtaining oil phase, (3) filtering the aqueous phase and the oil phase, mixing, emulsifying, (4) lowering the temperature to below 65 deg. C, charging emulsion foaming agent.

Description

technical field [0001] The invention relates to an emulsion explosive and a preparation method thereof. Background technique [0002] During the production and use of emulsion explosives, the storage period and working ability have become fatal problems for many manufacturers. At present, the storage period of emulsion explosives is usually 6 months, which cannot meet the requirements of export standards, and the export requires a storage period of more than 1 year. It is known that in order to prolong the storage period of emulsion explosives, domestic and foreign manufacturers increase the content of oil phase and add a large amount of sodium nitrate to reduce the crystallization point to prolong the storage period, but the disadvantage of this method is that the cost increases greatly. Contents of the invention [0003] The object of the present invention is to provide a kind of emulsified explosive with a storage period of more than 18 months and high working capacity...
