Abstract

Belonging to the technical field of blasting, the invention discloses a novel electronic detonator priming and a preparation method thereof. According to the invention, nickel hydrazine azide, magnesium powder, boron powder, potassium perchlorate, potassium chlorate, barium chromate and other components are adopted as the raw materials to prepare the priming. The electronic detonator priming provided by the invention has low ignition point and high detonation velocity, is conducive to reducing the action time of the electronic fusehead, generates high heat and sensitivity to flame during combustion, and can ignite basic detonators reliably. The electronic detonator fusehead prepared from the electronic priming provided by the invention has the characteristics of good ignition reliability and high delay time precision.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a novel electronic detonator ignition powder and a preparation method thereof. Background technique [0002] With the development of the blasting industry, the requirements for delay accuracy and safety of detonating equipment are getting higher and higher. Electronic detonators are increasingly valued by the industry for their high delay accuracy and high traceability. The general steps of burning the ignition charge of the electronic detonator can be divided into: electronic control module delay discharge process, module resistance heating process, and ignition charge combustion process. Therefore, whether the ignition powder can burn reliably directly determines the ignition performance of the electronic detonator. However, due to the limitation of electric capacity stored in the capacitor in the electronic detonator control module, after detonation, the electric energy rele...
