HEAT-STABLE MOULDED COMPOSITE EXPLOSIVES AND PRODUCTION THEREOF

摘要

The specification describes heat-stable pressuremoulded composite explosives which comprise at least one crystalline explosive having a high rate of detonation and, as a synthetic binder therefor, a cross-linked silicone resin. These composite explosives are produced by coating the crystalline explosive in the presence of water with a thermosetting polysiloxane prepolymer, then drying and crosslinking the moulding powder obtained, and finally coldcompressing the cross-linked moulding powder to form a shaped composite explosive. These explosives have exceptional mechanical strength at elevated temperatures which enables them to be used in all types of explosive charge. The process used provides increased safety and results in a lower cost price.
