Description
Technical Field
The invention belongs to the technical field of functional coatings, and particularly relates to an ultraviolet irradiation resistant low-absorptivity inorganic white thermal control coating and a preparation method thereof.
Background
Space is a high vacuum environment and heat exchange between the spacecraft and the external space is mainly carried out in the form of thermal radiation. The spacecraft which runs in the space environment is easy to generate high temperature due to solar radiation to influence the running of each component and equipment in the spacecraft, so the thermophysical property of the structural part or the equipment surface of the spacecraft plays a decisive role in the radiation heat exchange state. The function of the thermal control design is to select the coating reasonably and organize the heat exchange paths, processes and heat exchange quantities of the inner and outer surfaces of the spacecraft, so that the equipment and the structure reach a balanced temperature, and the environmental temperature of each equipment is ensured to be within the operating temperature working interval of the equipment, so that each equipment can run normally.
The application of the thermal control coating is the most widely, economically and simply applied measure in a thermal control system in the field of spacecrafts, and the thermal control coating mainly plays a role in passive temperature control and realizes heat exchange between the spacecrafts and the space environment. The photothermal properties of the thermal control coating are mainly determined by its own solar absorptance (alpha)s) And infrared emissivity (epsilon) characteristics to regulate the temperature of the spacecraft surface. Generally, the smaller the solar absorption ratio, the larger the infrared emissivity, and the better the temperature control performance. Spacecraft operating in space environments are susceptible to high vacuum, charged particle irradiation, ultraviolet irradiation, atomic oxygen erosion, high and low temperature difference changes and the like, and the environments can affect the optical and thermal properties of a spacecraft surface coating. However, although the solar ultraviolet light accounts for a small proportion in the space environment, the irradiation has higher energy, and has stronger irradiation damage effect on the coating, so that the change of the optical performance of the white thermal control coating is larger. In the current research, the inorganic thermal control coating still has poor adhesive force and high solar absorption, and particularly, the photo-thermal performance of the coating is reduced more after ultraviolet irradiation.
