Ignition mixtures

Abstract

A firing mixture which contains explosives, oxidizing and reducing agents is characterized in that it contains one or several explosives which can be fired by laser light. Also disclosed is a process for producing the same and its use.

1 . An igniter agent comprising at least one oxidizing agent, at least one reducing agent and polynitropolyphenyl ether or polynitropolyphenylene or mixtures of polynitropolyphenyl ether and polynitropolyphenylene, wherein the igniter agent can be ignited by laser light. 
     
     
         2 . The igniter agent according to  claim 1 , further comprising binders, combustion moderators, processing agents and/or compaction aids. 
     
     
         3 . The igniter agent according to  claim 1 , wherein the at least one oxidizing agent is selected from the group consisting of sulfur, peroxides of alkali or alkaline earth metals, zinc peroxide, peroxodisulfates of the aforementioned substances and of ammonium, nitrates of alkali and alkaline earth metals, oxohalogen compounds of alkali or alkaline earth metals or ammonium, and mixtures of the aforementioned substances. 
     
     
         4 . The igniter agent according to  claim 1 , wherein the at least one reducing agent is a metal selected from the group consisting of titanium, zirconium, aluminum, magnesium or cerium, a mixture of these metals, an alloy of these metals, carbon, boron, and a mixture of the aforementioned agents. 
     
     
         5 . The igniter agent according to  claim 1 , wherein the igniter agent is pigmented or coloring pigments are added thereto. 
     
     
         6 . The igniter agent according to  claim 1 , further comprising a combustion moderator capable, by heterogeneous or homogeneous catalysis, of influencing the combustion and its rate. 
     
     
         7 . The igniter agent according to  claim 1 , wherein the at least one oxidizing agent is lithium, sodium, potassium, strontium or ammonium nitrate or mixtures thereof. 
     
     
         8 . The igniter agent according to  claim 1 , wherein the at least one oxidizing agent is potassium perchlorate or ammonium perchlorate or mixtures thereof. 
     
     
         9 . The igniter agent according to  claim 1 , wherein the igniter agent includes polynitrophenylether, the at least one oxidizing agent is potassium nitrate, the at least one reducing agent is boron, and the igniter agent includes a binder comprising polyurethane. 
     
     
         10 . A process for production of the igniter agent according to  claim 1 , comprising mixing the individual components and then compacting the mixed components. 
     
     
         11 . A method for igniting an ignition mixture, comprising igniting an ignition mixture with laser light, the ignition mixture comprising at least one oxidizing agent, at least one reducing agent and polynitropolyphenyl ether or polynitropolyphenylene or mixtures of polynitropolyphenyl ether and polynitropolyphenylene. 
     
     
         12 . The method according to  claim 11 , wherein the at least one oxidizing agent is selected from the group consisting of sulfur, peroxides of alkali or alkaline earth metals, zinc peroxide, peroxodisulfates of the aforementioned substances and of ammonium, nitrates of alkali and alkaline earth metals, oxohalogen compounds of alkali or alkaline earth metals or ammonium, and mixtures of the aforementioned substances. 
     
     
         13 . The method according to  claim 11 , wherein the at least one reducing agent is a metal selected from the group consisting of titanium, zirconium, aluminum, magnesium or cerium, a mixture of these metals, an alloy of these metals, carbon, boron, and a mixture of the aforementioned agents. 
     
     
         14 . The method according to  claim 11 , wherein the igniter agent includes polynitrophenylether, the at least one oxidizing agent is potassium nitrate, the at least one reducing agent is boron, and the igniter agent includes a binder comprising polyurethane.
