Abstract

The invention discloses a green and environment-friendly explosive simulant material. The green and environment-friendly explosive simulant material contains the following ingredients in parts by weight: 0-30 parts of polytetrafluoroethylene, 0-35 parts of aluminum oxide, 0-14 parts of polyvinyl chloride, 19-30 parts of silicon dioxide, 30-40 parts of binder, 0.4-0.8 part of curing agent, 0.01-0.1 part of colorant, 0.02-0.08 part of surfactant and 0.25-2 parts of diluent. The invention further discloses a preparation method for the green and environment-friendly explosive simulant material. According to the preparation method, through adding green and environment-friendly simulant materials into a binder system, the explosive simulant material prepared through curing is not only good in formability, good in machined dimensional stability and uniform in product interior filling, but also can be used for accurately simulating the density and mechanical properties of real explosives.

Description

technical field [0001] The invention belongs to the field of civil energetic materials, and in particular relates to a green environment-friendly explosive simulation material and a preparation method thereof. Background technique [0002] Explosive simulation material is mainly an inert material used to simulate the charge density and mechanical properties of explosives. The products are mainly used for simulating assembly, transportation experiments, environmental tests, exhibition models, etc. The charge density, mechanical properties, and thermal conductivity of the simulated material must meet the requirements, that is, be equivalent to the simulated explosive; the inert material used in the formula is compatible with the contact material; there should be no delamination after the charge is formed. [0003] For a long time, the solid phase components of commonly used explosive simulation materials are barium nitrate (BN) and polyvinyl chloride (PVC). Using these simulat...
