【Task】 Infrared shielding fuming composition using red phosphorus as the main ingredient of the smoke generating agent improves infrared absorption efficiency (improves smoke density) and has a significantly high shielding effect not only in the visible light wavelength range but also in the infrared wavelength range. Infrared transmittance is significantly lowered in the far infrared wavelength region of -12 μm. [Solution] It has red phosphorus, an oxidizing agent selected from nitrates, sulfates, persulfates or oxides, a metal powder, and an energy binder. For example, red phosphorus 55 to 75% by weight and oxidizing agent 5 to 30% %, Metal powder 5 to 10% by weight, and energy binder 5 to 20% by weight. Here, the energy binder is selected from GAP (Glycidyl azide polymer), BAMMO (3,3-bis (azidomethyl) methyloxetane) or AMMO (3-azidomethyl-3-methyloxetane), and the oxidizing agent is clear. . |
