Abstract

The invention discloses a preparation method of an automatically charged explosive logic network. The preparation method comprises the following steps: firstly preparing micro-nano CL-20-based thermocuring explosive emulsion; sequentially mounting a base material and a mask on a supporting material, and then realizing direct writing deposition of micro-nano CL-20-based thermocuring explosive emulsion on the surface of a substrate by adopting graph data driving designed in advance; after liquid in to-be-exploded emulsion is volatilized, uncovering the mask to obtain patterned explosive, then needling an explosive deposited layer to form a needle type lead, finally packaging the explosive deposited layer with a packaging material, and shearing, so that the explosive logic network is obtained. The explosive logic network prepared by adopting the method is good in flexibility, explosive loading density is high, stable combustion and detonation can be realized, and the preparation method is safe and simple.

Description

[0001] Technical field: [0002] The invention relates to the field of blasting devices, in particular to a method for preparing an automatic charging explosive logic network. [0003] Background technique: [0004] The explosion network is a detonation transfer device composed of explosive elements, which selects and transmits different detonation instructions through the control of detonation signals. The detonation transfer path can be a flexible or rigid detonation transfer channel made of explosives or explosives. The application of explosive network technology can effectively reduce the detonation growth area of ​​explosives, thereby improving the utilization rate of detonation energy of explosive charges; at the same time, the explosive detonation waveform can also be controlled through the explosive network, which is helpful for improving the damage power of directional warheads is of great significance. [0005] However, the currently used network charging process is ...
