以堇青石、SiC、Cr2O3、TiO2、SiO2为原料，与磷酸盐胶粘结剂配料混匀后，经机械搅拌制备红外辐射涂料，采用刷涂的方式在高铝砖基体表面制备红外辐射节能涂层。采用TG-DSC研究分析红外辐射粉末的热稳定性，利用涂-4杯和漆膜附着力测定仪对涂料的流动性能和涂层与基体的结合强度进行表征，采用空冷和水淬方式研究涂层的抗热震性能，并探讨了碳化硅的含量对涂层红外发射率的影响。研究结果表明：胶粉比为2：1时，获得的涂料均匀，流动性最好；以磷酸盐胶粘结剂制备的红外辐射涂料经1100℃以上高温瓷化后，红外辐射涂层与基体的结合力增强，涂层抗热震性能良好；碳化硅含量为40%时，制备的复合红外辐射涂层具有最优的红外辐射性能。此外，在炭砖焙烧窑上使用该红外辐射涂料后，炉内温度提高了128℃，降低能耗8%左右。

Infrared radiation paint was prepared from cordierite, SiC, Cr2O3, TiO2, SiO2 as the initial raw material by mechanical mixing with phosphate adhesive. And then an energy-saving infrared radiation coating was prepared on high aluminum brick surface by brushing process. Thermal stability of the infrared radiation powders were investigated by Thermo Gravimetric-Differential Scanning Calorimeter (TG-DSC). The flowability of the prepared paint and the adhesion between infrared radiation coating and substrate were characterized by paint-4 cup and paint film adhesion tester. The thermal shock resistance of the obtained coating was investigated by water cooling and air cooling. The effect of SiC content on the emissivity of the coating was discussed. The research results show that:the paint is well-distributed and the flowability is quite good at the ratio 2:1 of adhesive to infrared radiation powders. The adhesion strength between coating and substrate increased after high temperature heat treatment at 1100℃. The thermal shock resistance of the coating was excellent. The emissivity of the infrared radiation coating containing 40%SiC is the highest, which can reach 0.91. Besides, the inner temperature of the baking furnace was increased by 128℃ after the energy-saving infrared radiation coating being used, and the energy consumption decreased 8%.
