Abstract
The invention discloses a eutectic explosive containing trinitrobenzene and 1-nitronaphthalene and a preparing method of the eutectic explosive, and belongs to the technical field of explosive eutectic. The trinitrobenzene and the 1-nitronaphthalene are bonded in a crystal of the same crystal lattice through the intermolecular force by adopting an evaporation solvent method or a suspension method. The thermal stability of the prepared eutectic explosive is greatly improved, the eutectic sensitivity is greatly reduced compared with that of a single-compound explosive, the eutectic melting point is lower than 100 DEG C, and the eutectic explosive can be used as a casting explosive component.
Description
Technical field
The invention belongs to explosive eutectic technical field, be specifically related to a kind of cocrystallized explosive containing sym-trinitrobenzene and 1-nitro-naphthalene and preparation method thereof.
