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 method for preparing continuous phase materials for emulsion explosives. Background technique [0002] Emulsion explosives are mainly composed of the inorganic oxidant salt solution component as the dispersed phase, the hydrocarbon fuel component as the continuous phase, the sensitized gas component (density modifier) ​​that forms the dispersed phase, and the emulsifier. Oil phase materials mainly play the role of continuous phase and combustion agent in emulsion explosives. Any hydrocarbons with suitable water-insoluble properties from different sources can be used as oil phase materials, including waxes, oils and polymers from various sources. Taking into account the easy emulsification performance and emulsion stability of the oil phase material during the emulsification process, it generally contains long-chain hydrocarbon components (such as paraffin) and short-chain hydrocarbon components (such as diesel, lubricating oil, et...
