Abstract

The invention provides a special composite oil phase for an emulsion explosive and a preparation method thereof, which belong to the technical field of explosive composition. The composite oil phase comprises Span-80, soybean lecithin, vaseline, a microcrystalline wax, a paraffin wax and a composite wax, wherein during producing the emulsion explosive, an emulsion and a blending wax are melted after being mixed or mixed after being melted according to a mass ratio of 1:2 so as to obtain the special composite oil phase for the emulsion explosive. By using the composite oil phase provided by the invention, the problems of low performance, over-quickness for damping detonation capacity as well as short storage period of the traditional emulsion explosive are solved; and the special composite oil phase for the emulsion explosive, provided by the invention, can be used for producing the special composite oil phase materials for the emulsion explosive.

Description

technical field [0001] The invention belongs to the technical field of explosive compositions, and in particular relates to a special composite oil phase for emulsion explosives and a preparation method thereof. Background technique [0002] Emulsion explosive is a kind of special water-in-oil type formed by the fine droplets of oxidant aqueous solution as the dispersed phase, suspended in the continuous medium composed of dispersed air bubbles or hollow glass microspheres or other porous materials like oily substances. emulsifying system. The oil phase material of emulsion explosives can be broadly understood as a class of water-insoluble organic compounds, whose main function is to form an oil film covering the inner phase particles. It forms a W / O emulsion together with the oxidant salt solution, which is one of the key components of emulsion explosives. The oil phase material must have good water resistance, suitable appearance, and be able to provide different viscosit...
