Abstract

The invention discloses a low-detonation-velocity ammonium oil explosive and a preparation method thereof, and relates to the technical field of industrial explosives. The low-detonation-velocity ammonium oil explosive is composed of the following raw materials in the following weight percentages: ammonium nitrate: 0.3-65.1%; oil phase: 3.7% ~4.2%; expanded perlite: 30.7~36.0%.

Description

technical field [0001] The invention relates to the technical field of industrial explosives, in particular to a low detonation velocity ammonium oil explosive and a preparation method thereof. Background technique [0002] Explosives currently used for explosive welding, marble mining and fruit forest loosening are mainly expanded ammonium nitrate explosives, which have the following disadvantages: (1) expanded explosives are easy to agglomerate; (2) storage stability is not good; (3) detonation velocity is unstable ,Not adjustable. In particular, the instability of the detonation velocity has caused a large number of waste products and unqualified metal explosion welding. [0003] The patent document "An open-air low-density modified ammonium oil explosive and its preparation method" (patent application number: 201910685246.X) discloses an open-air low-density modified ammonium oil explosive and its preparation method. Regulator B is added in different proportions to red...
