Flexible OSR second surface mirror thermal control coating and preparation method and application thereof

The invention provides a flexible OSR second surface mirror thermal control coating. The thermal control coating comprises a flexible glass substrate. One side of the flexible glass substrate is firstly coated with a metal reflecting layer and then coated with an anti-oxidation layer. If there is requirement on conductibility, the other side of the flexible glass substrate is coated with a conductive film layer. The fundamental principle of the invention is to adopt a vacuum magnetron sputtering and coating technology. By coating at two sides of the flexible glass substrate, the flexible OSR second surface mirror thermal control coating with a certain physical properties, namely solar absorptance (alpha s) and emittance (epsilon h) is obtained. The flexible OSR second surface mirror thermal control coating can be pasted onto a curved surface of spacecrafts such as a satellite, etc. to raise thermal control performance. Then, the problem that a traditional rigid OSR second surface mirror thermal control coating cannot realize curved surface pasting and a product is easy to crack is effectively solved; and application range of the OSR second surface mirror thermal control coating is widened.
