To glassy layer, glass inner layer, glass outer layer and one-way glass layer are bonded directly or indirectly through PVB film layers, one-way glass
Layer is compound glass, and two layers altogether of regular reflection film is interval with inside compound glass or outer surface；Regular reflection film is
High polymer complex film or fluoride plated film, fluoride plated film are the plated film of yttrium fluoride or praseodymium fluoride.
As preferred scheme, one layer of silicon carbide layer is additionally provided with outside the regular reflection film.
As preferred scheme, the thickness of the silicon carbide layer is 0.02-0.05mm.
As preferred scheme, the thickness of the glass inner layer is 1-6mm, and the thickness of glass outer layer is 1-5mm.
As preferred scheme, the glass inner layer or glass outer layer are spread glass, and one is provided with outer layer glass surface
Layer silicon nitride layer.
As preferred scheme, the glass inner layer or glass outer layer ion exposure have zinc oxide film.
Compared with prior art, beneficial effect is the utility model：The half mirror of preparation has well unidirectional
Transparent effect, positive transmitance is relatively low, and reflectivity is higher, and reverse side transmitance is higher, and reflectivity is relatively low；And heat absorption coefficient compared with
It is low.
