Abstract

The invention discloses a composite explosive molding process. In order to solve the problem that the pouring explosives cannot realize the orderly assembly of particles, the invention adopts the method of mechanical implantation to implant oxidant, reducing agent particles or composite explosives into the mixed explosives to prepare high-energy pouring PBX explosives, pyrotechnics, and propellants Wait. While achieving the purpose of orderly assembly of particles, the invention solves the problem of air bubbles in mechanical implantation through a vacuum process; by controlling the implantation time, it ensures that there is no crack defect in the charge after implantation. The molding process disclosed by the invention is divided into five steps: determining the implantation time, preparing the implanted particles, preparing the matrix, implanting the particles, orderly assembling the particles, and curing at high temperature. The invention is mainly applied in the fields of explosives and explosives.

Description

technical field

[0001] The invention belongs to the field of pyrotechnics and explosives, and relates to a molding process for composite explosives, in particular to a process for injecting strong oxidant or strong reducing agent particles into mixed explosives to prepare high-energy castable PBX explosives and pyrotechnics. Background technique

[0002] The cast PBX explosive is a polymer-based composite material in which the polymer is the matrix, the elemental explosive is the oxidant, and other compound particles are the reducing agent. The microstructure between the elemental components plays a decisive role in the detonation performance of the composite material.

[0003] The reaction of mixed explosives, pyrotechnics, and propellants is related to the structure and scale of the raw materials. The degree of combustion and detonation reaction, the severity of the reaction, and the damage effect can be adjusted through the structure of the raw materials. The document "Op...
