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

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 work performance have become fatal problems for many manufacturers. At present, the storage period of emulsion explosives is usually 6 months, which does not meet the requirements of export standards, and the export requires a storage period of more than 1 year. It is understood that in order to extend the storage period of emulsion explosives, domestic and foreign manufacturers have extended the storage period by increasing the content of the oil phase and adding a large amount of sodium nitrate to reduce the crystallization point. However, the disadvantage of this method is that the cost increases. Summary of the invention [0003] The purpose of the present invention is to provide an emulsion explosive with a storage period of more than 18 months and a great function, ...
