A safe ignition powder and preparation method

The present invention relates to a safety ignition powder and a preparation method, belonging to the field of energetic materials. The following composition: Carbon black 20 ~ 40%; 30% to 50% oxidizer; after coated calcium peroxide 15 to 30%; borohydride from 5 to 15%; binder A1 ~ 8%; the present invention is a secure Igniting safe. Coated with calcium peroxide prevents the reaction of calcium peroxide and borohydride, calcium peroxide and blocking other components of the reaction due to the impact, caused by friction, decreased sensitivity, and improve transport safety in use. Simple process. The present invention does not require the use of complex equipment, simple preparation process, the operation is simple, easy to continuous production.
