Waste HTPB Propellants as Ingredients in Novel Watergel Explosive
In order to dispose and reuse waste solid propellants safely, a novel type of watergel explosive containing waste hydroxyl-terminated polybutadiene (HTPB) propellants was proposed. The detonation performance of watergel explosive was tested through the witness plate test, and the detonation velocity was also measured. The Effect of single-base propellant content, particle size of HTPB propellant and charge diameter on the detonation properties of explosives were also studied. The results show that the HTPB propellant itself is hard to detonate, but if some single-base propellants are added in the charge, the impact sensitivity of explosives can be significantly improved. The density of the watergel explosive is about 1.6 g/cm3, and the detonation velocity is greater than 6500 m/s when the charge diameter is 70 mm. The watergel explosive can be used as an open-air commercial explosive with big charge diameter.
