Abstract
The present invention relates to a primer composition formed of TNT, DNT (2,4-dinitrotoluene) and fine particle size PETN (pentaerythritol tetranitrate) for use with explosive charges. This composition is extruded in melt condition into primer cartridges. Any topping-off operations are eliminated since practically no shrinkage occurs as the melt cools to form a solid casting in the cartridge.
Claims9
A homogeneous primer composition of uniform sensitivity for use with explosive charges consisting of about 50% by weight of the total composition of a nitrotoluene blend of 20-50%, dinitrotoluene (DNT) having a melting point of about 69.degree. C. with 50-80% of trinitrotoluene of about 80.degree. C., and about 50% of the total composition of finely granulated pentaerythritol tetranitrate (PETN) of 120-150 mesh size which remains in suspension in the nitrotoluene blend after being mixed with the nitrotoluene blend.
A primer unit for use with explosive charges comprising a hollow cartridge and a solidified homogeneous explosive composition of uniform sensitivity within said cartridge wherein said composition consists of about 50% by weight of the total composition of a nitrotoluene blend of 20-50% dinitrotoluene (DNT) having a melting point of about 69.degree. C. with 50-80% of trinitrotoluene having a melting point of about 80.degree. C, and about 50% of the total composition of finely granulated pentaerythritol tetranitrate (PETN) of 120-150 mesh size which is uniformly suspended in the nitrotoluene blend.
A primer composition of uniform sensitivity for use with explosive charges consisting of a nitrotoluene blend of 20-50%, dinitrotoluene (DNT) having a melting point of about 69.degree. C. with 50-80% of trinitrotoluene having a melting point of about 80.degree. C., and finely granulated pentaerythritol tetranitrate (PETN) of 120-150 mesh size which remains in suspension in the nitrotoluene blend after being mixed with the nitrotoluene blend.
