Problems solved by technology

The above-mentioned patents have made corresponding improvements to the quality and performance of the oil phase material of the emulsified explosive without any influence on the amount of emulsifier used.
[0004] As we all know, compared with wax materials, emulsifiers are expensive. At present, the amount of emulsifiers accounts for 1.5% of emulsion explosives. In order to improve the storage period of emulsion explosives, some explosive factories also increase the amount of emulsifiers accordingly. Production Cost of Emulsion Explosives

Abstract

The present invention discloses a preparation method for a continuous phase material of an emulsion explosive. The raw materials of the continuous phase material comprise, by weight, 0-20% of vacuum distillate oil, 70-95% of vacuum cerate, and 5-20% of residual oil cerate. According to the preparation method, a catalyst is added to the raw materials of the continuous phase material, wherein the weight of the catalyst is 0.1-1.0% of the weight of the raw materials of the continuous phase material; oxygen-containing gas is introduced to carry out a reaction for 2-10 hours at a temperature of 130-180 DEG C; phospholipid is added to the oxidation product to prepare the continuous phase material of the emulsion explosive, wherein the weight of the phospholipid is 0.1-5% of the weight of the raw materials of the continuous phase material. When the continuous phase material prepared by the method of the present invention is used for preparation of the emulsion explosive, the use amount of the emulsion can be substantially reduced under the premise of assurance of the product quality, such that the emulsion explosive production cost is reduced.

Description

technical field [0001] The invention relates to a preparation method of a continuous phase material used for emulsified explosives. Background technique [0002] Emulsion explosives are mainly composed of four parts: the inorganic oxidant salt solution component as the dispersed phase, the hydrocarbon fuel component as the continuous phase, the sensitizing gas component (density modifier) ​​forming the dispersed phase, and the emulsifier. The oil phase material mainly plays the role of the continuous phase and the combustion agent in the emulsion explosive. Any suitable hydrocarbon insoluble in water from different sources can be used as the oil phase material, including waxes, oils and polymers from various sources, but Considering the easy emulsification performance of the oil phase material in the emulsification process and the stability of the emulsion, it generally contains long-chain hydrocarbon components (such as paraffin) and short-chain hydrocarbon components (such...
