摘　　要：本文以SiO2、CaCO3、MgO、TiO2等为原料，利用高温烧制的方法，制备出了能够遮蔽8～14μm波长红外光和10．6μm、1．06μm波长激光的烟幕干扰材料。研究结果表明，当该烟幕干扰材料的平均粒径如为4.2μm时，具有很好的遮蔽效果，对8～14μm波长红外光和10．6μm激光遮蔽率≥85％（透过率≤15％），对1．06μm波长激光遮蔽率≥80％（透过率≤20％），同时又具有较长的持续遮蔽时间。In this paper, an Anti-infrared/laser compound smoke interfering material was described, which prepared from pure reagents of SiO2, CaCO3, MgO and TiO2 by the combustion at high temperature. The screening performance of the material at IR approximately 8～14μm and Laser wavelength 1.06μm, 10.6μm is excellent. As a results, when the average particle size of the sample was 4.2μm, the transmittance at 8 ～ 14μm and 10.6μm wavelength were below 15%, the transmittance at 1.06/1m wavelength was below 20%. The smoke interfering material possessed good screening effect and longer screening time.
