Abstract

The invention discloses a preparation method of a powdery emulsion explosive oil phase material. The oil phase material comprises 10-40% of petroleum wax, 50-85% of vacuum cerate, 0-20% of foots oil and 0-5% of a polymer. According to the weight of the oil phase, 0.1-1.0% of a catalyst is added to the oil phase; under a temperature of 130-180 DEG C, oxygen-containing gas is delivered into the oil phase, and the mixture is subject to a reaction for 2-10 hours; according to the weight of the oil phase, 0.1-5% of phosphatide is added to the oxidation product, such that the powdery emulsion explosive oil phase material is finally prepared. According to the invention, when the oil phase material is used for preparing the powdery emulsion explosive, the dosage of an emulsifying agent can be reduced to 1.0%, and the stability of the powdery emulsion explosive can be further improved.

Description

technical field [0001] The invention relates to a preparation method of an oil phase material used for powdery emulsion explosives. Background technique [0002] Powdery emulsion explosive is a new type of civil explosive with international advanced level invented in the late 1990s. It is made of supersaturated oxidant solution and oil phase under the action of emulsifier, emulsified at 140 ℃ and then spray-dried Made of powdered explosives. It not only has the excellent water resistance of emulsion explosives, does not contain TNT in components, is harmless to the environment and human body, conforms to the development trend of civil explosives without ladders, but also has the solid form characteristics of powdery ladderless explosives, and is stable in storage. High explosive power (working ability), more flexible and convenient to use, etc. The powdery emulsion explosive not only overcomes the poor stability of the emulsion explosive, but also overcomes the shortcoming...
