Abstract

The invention discloses an anti-overload explosive and a forming process thereof. The anti-overload explosive comprises the following components in percentage by mass: 52%-63% of octogen, 22%-33% of magnesium powder, 4%-6% of an ethylene-vinyl acetate copolymer, 3%-5% of 80# microcrystalline wax, 1%-3% of fatty alcohol-polyoxyethylene ether sodium sulfate and 3%-5% of dioctyl adipate. The anti-overload explosive is mainly used for charging the tail part of a penetration warhead, and is particularly suitable for charging the warhead of an aluminum-containing press-fitting explosive.

Description

technical field [0001] The invention relates to military explosives, in particular to an anti-overload explosive, which is mainly used for penetrating the tail of a warhead, and is especially suitable for the warhead filled with aluminum-containing press-packed explosives. Background technique [0002] The penetration warhead is mainly used to strike high-value targets such as underground construction facilities, ground reinforcement targets, and multi-storey buildings. It is required that the high-energy explosives loaded in the warhead remain stable during the penetration process, and finally achieve effective strikes on the target. Explosives have to withstand extremely high overload stress during the penetration process. Therefore, general high-energy explosives are difficult to withstand such a high penetration overload, and it is easy to cause the penetration warhead to explode before reaching the intended target. At the same time, because the penetrating warhead is mo...
