The invention provides an intelligent thermal control-infrared stealth function integrated coating, a preparation method thereof and a spacecraft, and relates to the field of thermal control coatings. The coating comprises a metal bonding layer, a thermochromic radiation layer and a heat sensitive layer which are arranged in a stacked mode, the metal bonding layer comprises MCrAlY alloy, M comprises nickel and/or cobalt, the thermochromic radiation layer comprises lanthanum manganate system ceramic, and the heat sensitive layer comprises one or more of Pt, Ag, Cu and Al. The coating has an infrared stealth function, through cooperation of the metal bonding layer, the thermochromic radiation layer, the heat sensitive layer and other multiple coatings, radiation absorption can be reduced, the radiance can be effectively adjusted along with temperature changes, the coating adapts to the temperature change environment in the space environment, the unique temperature sensing characteristic of the coating can effectively respond to the temperature changes, and the coating can be applied to infrared stealth. Interlayer heat transmission in the coating is controlled, the change of emissivity is rapidly adjusted, the multifunctional requirement can be met, meanwhile, the coating has the characteristics of being light and thin, and energy and resources are effectively saved.
