Abstract

The invention provides a novel bulk emulsion explosive and a preparation method thereof. The novel bulk emulsion explosive comprises an emulsion matrix and a sensitization material, wherein the emulsion matrix is prepared from the following components: ammonium nitrate, sodium nitrate, water, a combustible agent and an emulsifier. The sensitization material is prepared from hollow glass microspheres or plastic microspheres. The specific preparation method comprises the following steps: (1) preparing a water-phase solution; (2) preparing an oil-phase solution; (3) preparing the emulsion matrix;and (4) sensitizing by fully stirring the emulsion matrix with the sensitization material to prepare the novel bulk emulsion explosive. The novel bulk emulsion explosive prepared by the method is free of detonator sensitivity, meets the requirements of Manual of Tests and Criteria in Recommendations on the Transport of Dangerous Goods (Fifth Revised Edition) of United Nations, can be put in Item5.1, is an oxidizative material, belongs to non-explosive products, still has detonating projectile sensitivity, and is capable of rapidly reacting, releasing energy and doing work outwards.

Description

technical field [0001] The invention belongs to the technical field of industrial explosives, and in particular relates to a novel bulk emulsion explosive and a preparation method thereof. Background technique [0002] Emulsion explosive is a kind of water-in-oil type latex-like explosive which is uniformly dispersed in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres by means of the action of an emulsifier. Dynamite is a new type of industrial explosive developed in the 1970s. [0003] According to the packaging form, emulsion explosives can be divided into packaged emulsion explosives and bulk emulsion explosives. At present, the packaging of emulsion explosives basically adopts plastic film packaging materials to pack the colloidal drug body into a fixed-shaped drug roll, put the drug roll into a middle bag, and then put the middle bag into a carton or woven bag to complete the packaging of the emulsi...
