Embodiment Construction

[0026] Below in conjunction with accompanying drawing and preferred example the present invention will be described in further detail:

[0027] In the first step, zirconium (Zr) powder is mechanically ground, and its specific process parameters and procedures are:

[0028] 1.1 The Japanese planetary ball mill PL-1200 is adopted, which mainly consists of a mechanical part and a control part. The mechanical part is mainly composed of a turntable with a diameter of 60cm, on which there are three symmetrical self-rotating ball mill jars (φ130×80mm) and fasteners. The ball milling tank is a flying saucer-shaped tank with a capacity of 500ml, which is divided into a cavity part and a sealing cover. The ball milling bead is a zirconia ball with a diameter of φ2mm. Pour 500g of ball milling beads, 30g of zirconium powder and 70ml of deionized water into the ball milling jars of the ball mill. Wrench to tighten the screw. Put the three ball mill jars into the fixed position of the b...

Abstract

The invention discloses a preparation method of a ZPP (Zinc Protoporphyrin) insensitive ignition explosive, and belongs to the preparation field of initiating explosive medicaments. The preparation method comprises the following steps of: refining zirconium powder and potassium perchlorate; enabling the average particle diameter of the zirconium powder and the potassium perchlorate to be respectively less than 3mu m and 20mu m; evenly mixing the zirconium powder and the potassium perchlorate manually or mechanically; mixing the zirconium powder and the potassium perchlorate with a prepared nitrocotton acetone solution; volatilizing the acetone in a stirring manner; and collecting semi-dry medicament particles of 18 to 60 meshes and drying, thereby obtaining the ZPP insensitive ignition explosive as a finished product in the shape of a gray solid granule. The prepared ZPP insensitive ignition explosive is accurate in medicament content, can be stored for a long time and used at any time, and is suitable for the pressing charging of the medicaments in various shapes and density changes.

Description

technical field [0001] The invention belongs to the field of preparation of pyrotechnic agents, and mainly relates to a method for preparing an insensitive igniter, in particular to a method for preparing an insensitive igniter which can be used for an insensitive electric igniter. Background technique [0002] ZPP insensitive ignition powder (Zirconium potassium-perchlorate, referred to as ZPP) is composed of zirconium powder, potassium perchlorate and binder, and is an insensitive ignition powder. Insensitive ignition powder means that the sample is placed in the electric explosive product, and the minimum current of 1A is applied to the corresponding power of 1W DC, and the electrification time is at least 5min. ZPP insensitive ignition powder fully complies with the requirements of 1A1W5min, and is mainly used for ignition control of ignition or explosion sequences, and is widely used in ignition components in military and civilian fields. ZPP insensitive ignition powde...
