PYROTECHNIC SMOKE MATERIAL FOR OBSCRUING MULTI-SPECTRUM USING EXPANDED GRAPHITE AND RED PHOSPHORUS

摘要

The present invention relates to a combustion type multi-region screening smoke agent for smoke screen and deception, and more specifically, to a combustion type multi-region screening smoke agent which has impermeability in visible ray and ultraviolet ray band by combustion reaction materials of red phosphorus in the combustion, and provides a camouflage smokescreen which causes scattering absorption in millimeter wave band as expanded graphite is expanded, by comprising 30-50 wt% of red phosphorus, 20-40 wt% of expanded graphite, and 5-15 wt% of an alkali metal nitrate; 2-20 wt% of a composition selected from a group consisting of at least one type of metal selected from a group consisting of alkali earth metals and transition metals, alloy thereof, and at least one metalloid, and 0.5-8 wt% of a bonding agent.
