A Cl-20-based press-packed high-energy insensitive explosive and its preparation method

Abstract

The invention discloses a CL-20 based compact high-explosive insensitive explosive and a preparation method thereof. A novel preparation technology in-situ precipitation reaction method is adopted forpreparing the novel CL-20 based compact high-explosive insensitive explosive, and the CL-20 based compact high-explosive insensitive explosive aims to solve the problems of low formation density anddetonation velocity of CL-20 based compact explosives of existing preparation technologies. According to the preparation method of the CL-20 based compact high-explosive insensitive explosive, cladding and desensitization of the CL-20 explosive are achieved through an in-situ precipitation reaction process, an explosive formula of the CL-20 based compact high-explosive insensitive explosive is composed of CL-20, a binding agent and a desensitization agent, the mechanical sensitiveness of the existing CL-20 based compact explosives is effectively improved, and the formation density and energy output of the CL-20 based compact explosives are improved. The CL-20 based compact high-explosive insensitive explosive is mainly used for high explosive anti-tank cartridge and antitank missile warhead charging.

Description

technical field [0001] The invention relates to a CL-20-based press-packed high-energy insensitive explosive prepared by an in-situ reaction method, which belongs to a new formula mixed explosive prepared by a new process method, and is mainly used for charging armor-piercing projectiles and anti-tank missile warheads. Background technique [0002] With the development of weapon protection technologies such as tanks, a variety of new types of armor have emerged, which put forward higher requirements for the charge energy of armor-piercing ammunition. At present, CL-20-based armor-piercing bomb explosives usually use PBX explosives with a CL-20 explosive content of about 95%. LX-19 explosive is disclosed in No. 26, P1690-1694. The mass composition of LX-19 is CL-20 / Estane 5703-P=95.8 / 4.2, and the charge density is 1.920g / cm 3 , the detonation velocity is 9104m / s; the mechanical sensitivity is 36% for impact sensitivity and 32% for friction sensitivity. LX-19 explosive has ...

AI Technical Summary

Problems solved by technology

LX-19 explosive has the advantages of high detonation velocity and strong energy output; however, the main explosive content and charge density of this formula are relatively low, and the mechanical sensitivity of CL-20 explosive itself is relatively high, and the impact sensitivity and friction sensitivity are both 100 %; Therefore, the energy output and safety performance of LX-19 are limited, and cannot fully meet the armor-piercing damage requirements of the new reactive armor, and need to be further improved
