Abstract

The invention discloses a composite oil phase with nitromethane, in particular to the composite oil phase for powder type ammon explosives. The invention comprises the raw materials by weight proportions: 72 to 92 proportions of solid fuel oil, 5.0 to 20 proportions of liquid fuel oil, 2.0 to 5.0 proportions of nitromethane, and 1.0 to 3.0 proportions of condensation compounds of aromatic sulphonate and aldimine. The invention also discloses a preparation method thereof. The method comprises the steps as follow: the solid fuel oil is firstly melted, and liquid fuel oil, condensation compound of organic acid salt aldehydes and nitromethane are added in turn for being mixed fully, and then the mixture is cooled and packed. The invention is characterized in that the burning thermal value is high; the viscosity is small; and the dispersion on the surface of powder type ammonium nitrate grain to form a moisture proof anti-blocking water resistance oil membrane is easy, thus the detonation Sensitivity and the detonation energy of the powder type ammon explosives are improved. The utility model used for the powder type ammon explosives has the advantages that the oil phase with the nitromethane is simple and reliable, has low cost and facilitates the industrialization production and utilization.

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 ...
