Problems solved by technology

Thus, on the one hand, not only the preparation process of the emulsion explosive is cumbersome, but also because the added components are more, it is easier to cause fluctuations in the quality of the emulsion explosive, and the emulsification and emulsification stability of the emulsion explosive are also difficult to control; on the other hand On the one hand, for explosives manufacturers, it is necessary to reserve a lot of various raw materials in advance, which will lead to a serious backlog of funds, and will also cause unnecessary waste of manpower, material resources and energy in transportation, storage, etc.

Description

technical field [0001] The invention relates to the oil phase technology of explosives, in particular to an integrated oil phase of emulsion explosives and a preparation method thereof. Background technique [0002] Emulsion explosives generally refer to a class prepared by emulsification technology, so that the droplets of oxidant salt aqueous solution can be evenly dispersed in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil type explosive. latex-like aqueous industrial explosives. Emulsion explosive is a kind of industrial explosive that the civil explosive industry has vigorously promoted in recent years. This type of emulsion explosive has excellent performance, good water resistance, stable storage performance, and does not contain any toxic components. It is widely used in blasting operations such as infrastructure construction and mining. [0003] In the prior art, in the...
