Abstract

The invention relates to a preparation method of special oil for emulsion explosives and application of the special oil for the emulsion explosives in the emulsion explosives. The influence of impurity gas and bottom slag in reduced pressure distillation is reduced, the load on reduced pressure distillation equipment is reduced, and the reduced pressure distillation efficiency is improved; the obtained special oil for the emulsion explosive is low in residual amount of sulfur and carbon, basically free water is not contained, the flash point is high, the possibility of spontaneous combustion of an oil product in the steam heating production and transportation process can be effectively reduced, and the safety coefficient is improved; meanwhile, the special oil product for the emulsion explosive does not contain an additive in engine oil blending, so that the influence of the additive on the emulsifying effect of an emulsifier is avoided, and the quality stability of an emulsion matrix is improved; the emulsion explosive prepared from the special oil for the emulsion explosive is high in density, proper in detonation velocity and good in water resistance.

Description

technical field [0001] The invention relates to the field of emulsion explosives, to raw materials for the production of emulsion explosives in the civil explosive equipment industry, in particular to a preparation method of a special oil for emulsion explosives, and more particularly, to the application of the special oil for emulsion explosives to emulsion explosives . Background technique [0002] Emulsion explosive is a water-resistant industrial explosive formed by sensitizing a water-in-oil latex matrix prepared by emulsification technology. At present, ammonium nitrate aqueous solution and oil phase are emulsified in China. The oil phase is mainly prepared by mixing emulsifier, diesel oil and engine oil. In the mixed production process, steam heating is mostly used. Security risks. Due to the low flash point of ordinary diesel oil (45℃-65℃), it is classified as dangerous goods, and its procurement cost is high, and the safety management of production, transportation...
