Plastic-bonded pyrotechnical mixture for producing alkali metal chloride or earth alkali metal chloride aerosols as smokescreen

Abstract

A plastic-bonded pyrotechnical mixture is provided that includes at least one oxidatizer, one carbonate and/or phosphate from the group of alkali metals or earth alkali metals, a chlorinated rubber and a softener. An additional bonding agent and/or graphite can be added thereto as needed. The oxidatizer can be a perchlorate or a mixture of perchlorates from the group of alkali metals or earth alkali metals, or alternatively, ammonium perchlorates can also be integrated as an oxidatizer. The softener is an organic substance or substance mixture from the group of adipates or phthalates, or can be an organic phosphoric acid ester or a phosphoric acid ester mixture. As an additional bonding agent, an organic titanate or an organic titanate mixture is preferred. All components are mixed with one another at such a ratio that a neutral smoke in the pH range of 5-7 (bases on aerosol) is created.

1 . A plastic-bound pyrotechnic mixture comprising at least one oxidizer, a carbonate and/or phosphate or a mixture of carbonates and/or phosphates from the group of the alkali metals and/or alkaline earth metals, a chlorinated rubber, and a plasticizer. 
     
     
         2 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein all of the components are blended in a ratio to one another such that a neutral smoke in the range pH 5-7,relative to the aerosol is formed. 
     
     
         3 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein a further binder and/or a graphite is incorporated. 
     
     
         4 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein the oxidizer is a perchlorate or a mixture of perchlorates from the group of the alkali metals and/or alkaline earth metals. 
     
     
         5 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein, alternatively or additionally, ammonium perchlorate is incorporated as the oxidizer. 
     
     
         6 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein the plasticizer is an organic substance or substance mixture from the group of the adipates, citrates or phthalates. 
     
     
         7 . The plastic-bound pyrotechnic mixture of  claim 1 , wherein the plasticizer is an organic phosphoric ester or a phosphoric ester mixture. 
     
     
         8 . The plastic-bound pyrotechnic mixture of  claim 2 , wherein the additional binder is an organic titanate or an organic titanate mixture. 
     
     
         9 . Caseless and encased smoke grenades or munitions, smoke hand grenades, and fixed smoke application systems, wherein a plastic-bound pyrotechnic mixture according to  claim 1  is incorporated therein.
