Firework with integral module explosive filling structure in open mode and preparation method thereof

Abstract

The invention discloses a firework with an integral module explosive filing structure in an open mode and a preparation method thereof. The explosive filling structure disclosed by the invention comprises a shell, a delay fuse, bright beads and an open explosive module, wherein the shell, the delay fuse and the bright beads are made of traditional materials. The preparation method of the fireworkwith the integral module explosive filling structure in an open mode comprises the following steps: preparing a slurry containing an organic adhesive, an ignition performance reinforcing agent and granular micro-pore firework explosive granules; then, filling the bright beads and the slurry into the ball shell of the firework according to the needed structure, thus forming an integral module structure; and finishing the preparation of the firework according to a conventional method. By adopting the integral module explosive filling structure and the explosive filling method, the gap between the open explosive module and the bright beads is basically eliminated; the ignition rate of the bright beads can be improved; the mechanical friction action among the granules in the explosive fillingcourse and storage and transportation course of the granules is avoided; and the safety of the preparation course and storage and transportation course of fireworks is improved.

Description

technical field

[0001] The invention belongs to the technology of opening buds of fireworks bombs, in particular to a fireworks bomb with an integral module bud opening charge structure and a preparation method thereof. Background technique

[0002] The traditional fireworks popping explosives are made of black powder as the main explosive material. Usually, black powder is mixed with a small amount of binder, and a large amount of low-density filling materials such as rice husk or cottonseed husk are added. Stick the black gunpowder to the surface of the granular filler, and dry it to become a granular budding medicine. This bud-opening drug has been used for hundreds of years. It is characterized by a wide range of sources of raw materials and is relatively easy to make, but it also brings about the problem of unstable material properties. In addition, during the bud opening process of this kind of budding medicine, the filling materials such as black powder and rice husk...
