Abstract

The invention discloses a metal accelerated explosive and a preparation method thereof, and aims to solve the problem of low acceleration capability of the existing metal acceleration type explosive.The metal accelerated explosive comprises the following components in percentage by mass: 75%-83% of 3, 4-dinitrofurazan-based furazan oxide (D5030 [mu]m to 40 [mu]m), 15%-20% of nano aluminum powder(D50100nm to 200nm), 1%-4% of ethylene-vinyl acetate copolymer (EVA, model 28 / 150) and 1%-4% of paraffin (68 #). The preparation method comprises the following steps: preparing composite particles ofnano aluminum powder and 3, 4-dinitrofurazan-based furazan oxide (DNTF), and carrying out coating granulation by using EVA and paraffin to complete the preparation of the metal accelerated explosive molding powder. According to the explosive, on the premise that safety is guaranteed, high metal driving capacity can be achieved. The charging device is suitable for charging of armor-breaking warheads and explosion-killing warheads.

Description

technical field

[0001] The application relates to a metal-accelerated explosive and a preparation method thereof, which is suitable for charging an anti-armor warhead and an anti-explosion warhead, and belongs to a mixed explosive. Background technique

[0002] 3,4-Dinitrofurazanyl furazan oxide is a new type of high energy density material, which integrates furazan, furazan oxide and nitrate base, with a density of 1.937g cm -3 , detonation velocity 9250m·s -1 , explosive heat 5798J·g -1 , has the advantages of high density and high energy, and is the only energetic material that can compete with hexanitrohexaazaisopentazane in energy at this stage.

[0003] The armor-piercing warheads or fragmentation warheads currently in use in China need to be loaded with explosive charges with strong metal acceleration capabilities. At present, high-explosive-pressure mixed explosives with high content of main explosives are generally used, among which RDX, HMX, etc. are mostly used ...
