Low-detonation-velocity explosive with adjustable detonation velocity and brisance and preparation process thereof

Abstract

The invention provides a low-detonation-velocity explosive with adjustable detonation velocity and brisance and a preparation process thereof. According to the technical scheme, the low-detonation-velocity explosive is prepared by mixing the following components in percentage by mass: 52%-73% of ammonium nitrate, 2.0%-3.0% of a complex oil phase, 3%-16% of wood powder, 20%-30% of industrial salt and 0.3%-0.42% of a modifier. By the low-detonation-velocity explosive with adjustable detonation velocity and brisance, such problems of the existing explosive for explosive welding as high sensitivity, uneven explosive mixing, poor safety, poor fluidity, instable detonation velocity and the like are solved.

Description

technical field

[0001] The invention belongs to the technical field of explosive manufacture, in particular to a low-detonation-velocity explosive with adjustable detonation velocity and intensity. Background technique

[0002] Explosive welding is to use the energy generated by the explosion of explosives to make the doubler plate collide with the substrate at a very high speed, so that the interface between the two metal plates produces local severe plastic deformation and is tightly combined to form a good welding interface. This technology has been widely used in national defense, shipbuilding, petrochemical, metallurgy and other departments. As an energy source for explosive welding, the performance of low-velocity explosives will directly affect the quality of explosive welding. At present, there are mainly three production methods of low detonation velocity explosives in the explosive welding process at home and abroad. One method is to add heavy metal powder to the ...
