空心微珠基红外低发射率材料研究

Study on Hollow Particles Based Low Infrared Emissivity Material

利用化学镀镍工艺制备空心微珠基红外低发射率材料,对其表面形貌,并重点对其吸收率、发射率和热辐射能等红外性能进行表征。SEM表征表明:材料表面包覆完整、毛刺较少。研究表明:材料在8～14μm波段平均红外吸收率从34.2%降至13.9%;红外发射率从0.85降至0.65;红外热辐射能较包覆前明显降低,且低于常用金属填料,在低发射率红外隐身涂料研制领域具有广泛应用前景。

Low infrared emissivity materials based on hollow particles are prepared by chemical Ni-coated processing, and surface morphology, absorbance, emissivity and infrared radiant energy are characterized. Hollow particles is fully packaged by Ni-P films and shown as few needle things on surface by SEM. IR, DSC demonstrates that the materials absorbance can be decreased from 34.2% to 13.9%, and infrared emissivity can be decreased from 0.85 to 0.65 at waveband of 8～14 μm, and infrared radiant energy is lower than ones of other metal fillers greatly. Then it is hopeful to be applied in research field of low emissivity infrared hidden coat.
