摘　　要：以过渡金属氧化物Fe2O3、MnO2为主要组分，掺入NiO、Co3O3、CuO，通过固相烧结制备红外辐射材料；优选发射率较高的A、B试样与堇青石复合制备堇青石一过渡金属氧化物红外辐射材料，并将制得的红外辐射材料作为功能填料制备辐射型隔热涂料，并对其隔热机理进行了探讨。研究表明：添加40wt％试样B制备的堇青石一过渡金属氧化物复合红外辐射材料8—14um的红外发射率达95．4％；以TBH为成膜基料，添加2．0g堇青石-过渡金属氧化物红外辐射材料为填料制备隔热涂料的热反射率达73．2％。The infrared radiation materials were prepared with Fe203 and MnO2 as the primary constituent, and doped with the appropriate proportion of NiO, Co2O3 and CuO by solid state sintering. Cordierite-transition metal oxide infrared radiation materials were prepared with A and B samples which were selected for their high emissivity. With the prepared infrared radiation materials as functional fillers, radiation heat-insulated paint was developed. And the heat-insulated mechanism of radiation heat-insulated paint was also discussed. Research indicates that the infrared emissivity of the cordierite-transition metal oxide infrared radiation materials doped with 40wt% B sample can reach 95.4% in 8 ~ 14um wavelength. The heat reflectance of the radiation heat-insulated paint, which is based on TBH emulsion as the binder and adding 2.0g cordierite-transition metal oxide as fillers, can reach 73. 2%.
