Abstract

The invention discloses an in-situ self-assembled slapper ignition component and a preparation method thereof. Specifically, the in-situ self-assembled slapper ignition component comprises a pin equipped alumina ceramic substrate, a metal copper exploding foil, a Parylene C slapper layer, a photoresist structural layer and an acceleration chamber. The metal copper exploding foil is disposed on the alumina ceramic substrate, the Parylene C slapper layer is arranged on the metal copper exploding foil, the photoresist structural layer is disposed on the Parylene C slapper layer, and the acceleration chamber is disposed in the photoresist structural layer. The component provided by the invention has the characteristics of self-assembly and flexibility, and can meet the production needs of various slapper ignition components with different specifications. According to the invention, photoresist is applied to preparation of the acceleration chamber and tempering modification treatment thereon so as to further strengthen the mechanical properties. Thus, the acceleration chamber can effectively shear slappers.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a flexible preparation method of an in-situ self-assembled integrated shock plate ignition component. Background technique [0002] Shock disc detonators are highly safe and reliable and are used in in-line detonation systems. A shock detonator is usually composed of a substrate, an explosive bridge foil, a flyer, an accelerating chamber, and a priming charge. Explosive foils are made by copper plating and etching on insulating ceramic substrates. Polyimide or polyester films bonded to the explosive foils are used as flyers. Between the flyers and the priming charge is an aperture of about Acceleration chamber with 1.5 times the width of the bridge area. When the shock detonator acts, the explosive foil undergoes an electric explosion under the action of a high-energy pulse, and generates plasma to drive the flyer to move. The flyer passes through the shearing of the accel...
