AI Technical Summary
Existing thermal control coatings for spacecraft are prone to decomposition and peeling under high temperature and high-speed airflow conditions, which cannot meet the aerodynamic thermal environment requirements of large-sized reusable spacecraft during the rocket ascent phase, and cannot simultaneously possess resistance to alternating high and low temperatures, resistance to space radiation, and rain protection.
It adopts a multi-layer composite coating structure, including a bottom layer, a middle layer and a top layer. The bottom layer is a high-temperature resistant coating, the middle layer is a thermally conductive coating, and the top layer is a low-absorption coating. Through the design of interfacial bonding and thermal conductivity, a coating that is heat-insulating, waterproof and resistant to high-temperature airflow is formed.
The coating exhibits good stability under high-temperature and high-speed airflow, provides long-term heat preservation, prevents the substrate from burning due to heat, has rainproof properties, adapts to various harsh environments, has strong coating adhesion, and stable thermal radiation performance.
