Benefits of technology

[0010] The present invention is a heavy-metal free primer composition consisting essentially of potassium dinitrobenzofuroxane as a primary explosive, diazodinitrophenol as a secondary sensitization explosive, and an inert sensitizer. The preferred mix is comprised of 50% of potassium dinitrobenzofuroxane, 30% of diazodinitrophenol and 20% of ceramics powder as the inert sensitizer. This composition has sufficient sensitivity, good ballistic properties for all types of the cartridges, and very strong stability in high temperature and high humidity conditions.

Problems solved by technology

This is true despite the fact that the by-products of firing such a composition include lead, which is considered toxic and, hence, such compositions are widely recognized as undesirable.

Embodiment Construction

[0015] According to the disclosure in Russian patent RU 2175652, incorporated herein by reference, which is a primer composition containing (% of weights): lead styphnate (60-75%), diazodinitrophenol (10-20%), and inert sensitizer (15-20%), the test primers have shown good results when checked for stability of the ballistic characteristics in a range of temperatures from −15° C. up to +50° C., high thermostability and moisture resistance. The increased time of a shot at negative temperatures is a problem of this composition. At temperatures of a −50° C., hang fires and misfires were observed. Additionally, this composition is not free of heavy metals.

[0016] The present invention provides an improvement over RU 2175652. It demonstrates stability of the ballistic characteristics and an increase of the reliability of ignition of a propellant charge in a range of temperatures +50° C. to −50° C. as well as preservation of high thermo and moisture resistance. Moreover, it is a non-corros...

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of priority from provisional patent application 60 / 482,643.FIELD OF THE INVENTION [0002] The present invention relates to ammunition primers, namely to the percussion pyrotechnical compositions for small arms ammunition primers. BACKGROUND OF THE INVENTION [0003] At present, there is a biological and environmental problem before designers of ammunition. The problem is that the components in ammunition primers are harmful to people and nature. These components are especially toxic when shooting in small areas and enclosed premises, including indoor shooting galleries. The solution requires a significant reduction in the use of these harmful components. [0004] The current technology for percussion pyrotechnical compositions (“PCC”) includes a combination of mercury fulminate (Hg(ONC)2), potassium chlorate (KCLO3) and antimony sulfide (Sb2S3). However, this composition is not ideal since its combustion i...
