Micro-priming powder for detonator

Abstract

The invention relates to micro initiating explosive for an exploder, and solves the problems of insecurity of the exploder with the initiating explosive and high cost of the exploder without the initiating explosive. The micro initiating explosive comprises more than one high explosive and more than one initiating explosive. The high explosive comprises hexogen and PETN; the initiating explosive comprises dinitrodiazophenol, lead azide, lead trinitroresorcinate, nickel hydrazine nitrate and perchloric acid tricarbohydrazide cadmium complex; and the more than one high explosive and the more than one initiating explosive are mixed to prepare the micro initiating explosive. Adhesive and surfactant can also be used. The micro initiating explosive has the advantages that the micro initiating explosive can reduce the content of the initiating explosive by 30 to 60 percent compared with the conventional exploder filled with the explosive, lower 20 to 30 percent of cost compared with the prior exploder, improve safety during assembly of the exploder, reduce static electricity, friction, impact and light and heat sensitivity while ensuring initiating force and flame sensitivity, improve safety during production, transportation, storage and use of the exploders, can reduce explosive feeding amount of the exploder, and improve free-running property of preparations.

Description

technical field [0001] The present invention relates to an explosive for a detonator, that is, a microprime detonator. Background technique [0002] At present, the production of industrial and military detonators all use primers, and the amount of primers is very large. These primary explosives discharge a large amount of toxic water containing mercury, lead, azos or phenols during the production process. If they are not treated, they will seriously pollute the environment, and bulk primary explosives are prohibited from being transported. Each detonator factory has to separate The establishment of explosives workshops will increase the number of pollution points and require more investment in environmental protection. Therefore, existing detonators all have safety problems in production, transportation, storage and use. [0003] The No. 3,978,791 U.S. Patent issued in September, 1976 discloses a flyer-type non-primer detonator. It uses low voltage and small current to p...
