Abstract

The invention discloses an explosive composition and a preparation method thereof and belongs to the field of chemical industry. The explosive composition disclosed by the invention comprises: fuel oil, a throwing agent, ammonium nitrate particles, a cracking agent, an expanding agent and an electrolyte solution; the explosive composition comprises the raw materials in parts by weight: 10 to 20 parts of the fuel oil, 20 to 40 parts of the throwing agent, 20 to 30 parts of the ammonium nitrate particles, 10 to 30 parts of the cracking agent, 20 to 30 parts of the expanding agent and 50 to 70 parts of the electrolyte solution; the explosive composition disclosed by the invention adopts a reasonable proportion design; a combustible agent is selected from a mixture composed of wood charcoal, aluminum powder and magnesium powder; compared with a wood charcoal combustible agent, the aluminum powder and the magnesium powder have high combustion calorific value; compared with an explosive composition in the prior art, the explosive composition generates a relatively great impact wave component force in an explosion process; the explosion strength is ideal, and the explosion performance ofexplosive and solid fuel is stable; and the explosive composition and the preparation method thereof are worthy of being popularized and applied.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an explosive composition and a preparation method thereof. Background technique [0002] In the process of national economic and social development, mining is an important operation. It not only guarantees the basic mineral materials needed to maintain the development of the national economy, but more importantly, it has an irreplaceable advantage in maintaining the stability and innovation of the national military industry. [0003] In the patent application document with the patent application number CN200980124791.6, an explosive composition is proposed. The solid fuel is natural synthetic rubber, and the binder is a mixed adhesive composed of polyisobutylene, polystyrene, polyethylene and polybutylene. Binder, obviously, it can use the same solid fuel particles for different purposes, resulting in the predictability and stability of the explosion results, but this explosive c...
