Radiation protection thermal control coating and its manufacturing method

The invention discloses a kind of radiation protection thermal control coatings, and the coating is using low atomic number material as the surface covering of thermal control coating, inter coat of the middle atomic number material as thermal control coating, primer coating of the high atomic number material as thermal control coating.Coating of the invention, under same surface density, compared with ZnO coating, 10% or more radiation protection capability improving, and coating solar absorptance α s is about 0.152, thermal emissivity e is about 0.886, suitable with ZnO white paint.
