A high-energy insensitive pressure-packed polymer bonded explosive

Abstract

The invention relates to a high energy insensitive press-fitting high polymer bonded explosive which is prepared from the following components in percentages by weight: 45-75% of main body explosive,5-20% of auxiliary explosive, 15-30% of metal fuel, 1-5% of an adhesive and 1-3% of an insensitive agent, wherein the main body explosive is TKX-50. In order to solve the existing problem that press-fitting PBX is not compatible in power properties and low vulnerability, a high energy insensitive explosive system is introduced. By adding the high energy insensitive main body explosive, the PBX formula has good power properties and low vulnerability. The detonation velocity of the explosive formula is greater than 7500m / s, the explosion heat is greater than 7500J / g, the power is greater than 1.85TNT (2,4,6-trinitrotoluene), and meanwhile, the friction sensitivity of the explosive formula is smaller than 20%, the impact sense is 0, and the explosive can pass examinations of low vulnerabilitytest items such as quick cook-off, slow cook-off and bullet impact.

Description

technical field

[0001] The invention relates to a polymer bonded explosive (hereinafter abbreviated as PBX), specifically a high-energy insensitive pressure-packed polymer bonded explosive, which belongs to the field of propellant and explosive formula development. Background technique

[0002] Since the development of low-fragility explosives was proposed in the early 1980s, the related research has been highly valued by countries all over the world, and many new low-fragility explosive formulations have been introduced. With the United States, NATO and others emphasizing the development of insensitive munitions (IM ), low-vulnerability explosives have entered the stage of large-scale promotion and application. At present, the low-fragile explosives researched and applied abroad are mainly high-quality RDX (hereinafter abbreviated as RDX), high-quality Octogen (hereinafter abbreviated as HMX), 3-nitro-1,2,4-triazole -5-ketone (hereinafter abbreviated as NTO), 1,3,5-triamin...
