Environment-friendly chromium-containing spinel infrared radiation coating and preparation method thereof
The invention relates to an environment-friendly chromium-containing spinel infrared radiation coating and a preparation method thereof. According to the technical scheme, the environment-friendly chromium-containing spinel infrared radiation coating is composed of a transition layer and a working layer. Aluminum-chromium solid solution fine powder, zirconium oxide fine powder and silica sol are used as transition layer raw materials, titanium-iron co-doped magnesium-chromium spinel fine powder, aluminum-chromium solid solution fine powder, boron-containing glass powder, silica powder and an aluminum dihydrogen phosphate solution are used as working layer raw materials, the two raw materials are mixed with deionized water and subjected to ball milling, and transition layer slurry and working layer slurry are obtained. And sequentially coating the transition layer slurry and the working layer slurry on the surface of the aluminum-silicon refractory brick, and drying to obtain the environment-friendly chromium-containing spinel infrared radiation coating. The environment-friendly chromium-containing spinel infrared radiation coating prepared by the method is suitable for a high-temperature environment of more than 1400 DEG C, can be firmly combined with a matrix, and can stably play a radiation role and hexavalent chromium meets the emission standard.
