摘要（英）：

The invention provides a high-temperature radiation coating, which is prepared from infrared radiation powder, a bonding agent, a suspension agent and a deflocculating agent; the infrared radiation powder is prepared from 20 to 40 weight percent of FeTiO3, 10 to 30 weight percent of Cr2O3, 5 to 10 weight percent of SiO2, 1 to 5 weight percent of MnO2, 10 to 20 weight percent of Co2O3, 1 to 5 weight percent of HfO2 and 5 to 10 weight percent of Nb2O3. The invention also discloses a preparation method of the high-temperature radiation coating. The prepared high-temperature radiation coating has the advantages that the temperature resistance is high; good infrared radiation performance is realized; the bonding intensity with a high-temperature furnace body is high; the heat vibration performance is good; in a use process, cracking and peeling cannot easily occur; the service life is long. Experiment results show that the prepared coating can resist the temperature of 1800 DEG C; the radiation rate is higher than or equal to 0.87; the vibration resistance at 1300 DEG C is greater than or equal to 6 times; the paint thickness is 0.3 to 2mm; the service life is greater than or equal to six years.
