摘要
烟幕具有"隐真"和"示假"双重功能,是一种重要的对抗技术。红外烟幕干扰材料是近几年重点发展的烟幕材料之一,红外吸收陶瓷材料是一种对红外线具有高吸收率的无机材料。本文以SiO2、Al2O3、MgCO3、TiO2等为原料,利用高温烧制的方法,制备出了对8～14μm波长红外光具有很好遮蔽效果的陶瓷烟幕干扰剂材料。研究结果表明,当该陶瓷烟幕干扰剂材料的平均粒径d50为4.2μm时,既具有很好的遮蔽效果,遮蔽率≥85%(透过率≤15%),又具有较长的持续遮蔽时间。同时还有良好的热稳定性和储存性能。
Smoke screen is an important electro-optical counter measure. IR-smoke screen interfering material has become an international hotspot of investigation and development. An infrared aerosol material prepared from pure reagents of SiO2, Al2O3, MgCO3 and TiO2 by the combustion at high temperature was described. The extinction effect of this aerosol material at IR wavelength approximately 8 - 14 μm is excellent. The experimental results indicated when the average particle size is 4.2 μm, the infrared ceramic smoke screen material possesses good screening effect (transmittance [less-than or equal to] 15%), longer screening time, better thermal stability and storage performance.
