Abstract
The invention discloses an ultrahigh-reflectivity composite material and a preparation method thereof. The high-reflectivity composite material is composed of a base material, an affinity layer, a metal coating layer and a protective layer from bottom to top, wherein the protective layer is composed of a first protective layer and a second protective layer and is a coating of oxide, fluoride and the like. When visible light radiates to the first protective layer, a part of light is reflected to atmosphere, the other part of light transmits the first protective layer to arrive at the surface of the second protective layer, a part of light is reflected by the first protective layer, the surplus light transmits the second protective layer to arrive at the surface of the metal coating layer, a small part of light is absorbed by the metal coating layer, and the rest most of light is basically subjected to total reflection to be reflected to the atmosphere after transmitting the second protective layer and the first protective layer. Therefore, the composite material has extremely high reflectivity to a visible light region, and is an ultrahigh-reflectivity material; and the highest reflectivity is up to 98%.
