摘要： 基于红外辐射产生机理，采用过渡区金属氧化物掺杂、高温固相烧结法制备陶瓷红外辐射材料，通过正交试验优化工艺条件，并确定配方，制得的红外辐射粉经 XRD表征，生成了高红外活性的四氧二铁酸钴反尖晶石相，在 26°C，8~13.5μm波段“大气窗口”的发射率大于 94%。以此红外材料为功能填料，氟碳乳液为基料，辅以其他颜填料及助剂，制得了在“大气窗口”波段内发射率大于 78%的外墙节能涂料，SEM测试表明漆膜表面平整紧密，其他基本性能良好。

Abstract: The infrared emissivity ceramic material was prepared by the methods of transition metal oxides doping and high temperature solid phase sintering based on the mechanism of infrared radiation.The process conditions and formula were optimized and determined by orthogonal design experiments. The products accoding was characterized by XRD. The results showed that the high-infrared activity anti-spinel cobalt diiron tetraoxide was formed, which provided the infrared emissivity powder a high emissivity higher than 94% at the wave length of 8~13. 5 μm, called "atmospheric window"at 26 ℃. And then, the infrared emissivity coatings for exterior wall was perpared based on the infrared powder as founctional filler and fluo-rocarbon latex as film material. The infrared emissivity was higher than 78% at the"atmospheric window".The results of SEM showed that the film of coatings was smooth and dense, the other properties were qualified.
