The invention provides a thermochemical protective coating material, the thermochemical protective coating material comprises an ABO 3 perovskite material or a ternary composite metal oxide doped with lithium, and the A site of the ABO 3 perovskite material is La , a combination of any two or more of Ca, Ba, Sr, and K, and/or, the B site of the ABO 3 perovskite material is a combination of any two or three of Mn, Fe, and Co. The thermochemical protective coating material can adjust the reaction temperature by changing the molar ratio of the composite metal oxide according to different requirements, thereby overcoming the shortcoming of the narrow temperature range of the single metal oxide heat storage material. The material is sprayed on the surface of the heat sink, which can improve the heat resistance of the heat sink itself and prolong the service life of the heat sink. |
