Abstract

The invention discloses an explosive special for powdery emulsion explosive welding and a preparation method thereof and relates to the technical field of explosives. The explosive special for powdery emulsion explosive welding comprises the following components in percentage by weight: 90.5 percent of ammonium nitrate, 3.8 percent of complex wax, 1.0 percent of rosin, 1.2 percent of emulsifying agent and 3.5 percent of water at the pH value of 7. The preparation method comprises the following steps: performing aqueous phase preparation, oil phase preparation, emulsification, powder preparation by spraying, cooling and discharging on the materials according to a specific technological procedure to obtain a basic explosive special for powdery emulsion explosive welding; uniformly mixing 100 weight percent of the basic explosive special for powdery emulsion explosive welding with 13-15 percent of porous granular ammonium nitrate, 8-10 percent of talcum powder and 8-10 percent of wood flour to obtain the explosive special for powdery emulsion explosive welding. The explosive velocity of the explosive is 2400-2700m / s, the requirements of explosive welding processes of various metal composite materials can be met, the component formula is reasonable, the production process is simple, a novel process device is not required to be increased, and the explosive can be industrially produced in a large scale. The explosive can be applied to all powdery emulsion explosive manufacturing enterprises.

Description

technical field [0001] The invention relates to the technical field of explosives, in particular to a special powdery emulsified explosive for explosive welding and a preparation method thereof. Background technique [0002] Explosion welding is a solid phase welding method, usually used for welding between dissimilar metals. Modern industry needs a variety of metal composite materials, such as titanium steel and carbon steel, stainless steel and carbon steel welded composite plates...etc. Titanium, copper, aluminum, steel and other metal materials with different chemical compositions and physical properties It is difficult to achieve welding with other welding methods. And modern industry needs a variety of metal composite materials, so the explosive welding process came into being. Explosion welding is to use the energy of explosives to weld two (or more) composite materials together under the action of detonation waves to achieve high-speed oblique collision. As a spec...
