Abstract

The invention discloses a composite oil phase containing nitromethane, especially a composite oil phase for powdery ammonium nitrate explosives, comprising the following raw materials in parts by weight: solid fuel oil 72-92, liquid fuel oil 5.0-20, Nitromethane 2.0-5.0, beta naphthalene sulfonic acid sodium salt and formaldehyde condensate 1.0-3.0, the invention also discloses its production method. The method is as follows: after melting the solid fuel oil, adding liquid fuel oil, organic acid salt aldehyde condensate and nitromethane respectively in sequence, stirring and mixing, and packing after cooling. The invention has the advantages of high combustion calorific value, low viscosity, easy dispersion on the surface of powdered ammonium nitrate particles, and the formation of a moisture-proof, caking-proof and water-resistant oil film. Increased the detonation sensitivity and explosion energy of powdered ammonium nitrate explosives. The compound oil phase process for the powdery ammonium nitrate explosive of the present invention is simple, reliable and low in cost, and is convenient for industrialized production and application.

Description

technical field [0001] The invention relates to a composite oil phase containing nitromethane for powdery ammonium nitrate explosive. Background technique [0002] In the ammonium ladder explosive composed of ammonium nitrate, TNT and wood powder, due to the existence of the TNT single substance explosive sensitizer, the explosive performance of the explosive is stable and reliable. However, TNT is poisonous and pollutes the environment. Therefore, in recent years, TNT sensitizers have been canceled in explosives, and fuel oil has been used to replace TNT to produce a powdery ammonium nitrate explosive without TNT sensitization, which makes the production non-toxic and harmless. , This is of great significance for improving environmental quality. [0003] But, in the powdery ammonium nitrate explosive that is made up of ammonium nitrate, fuel oil and wood flour, owing to do not have TNT elemental explosive sensitizer, the detonation sensitivity and explosive performance of ...
