Fig. 1 is a solar energy reflection mirror structural representation of the present utility model
Embodiment:
Referring to shown in Figure 1, solar energy reflection mirror of the present utility model, order is made up of glass substrate 1, metallic reflector 2, coat of metal 3, hard protective seam 4 and protective paint 5, mutually combines by sputter coating process between the adjacent layer.Wherein, glass substrate 1, metallic reflector 2, coat of metal 3 and protective paint 5 all can adopt existing solar energy reflection mirror structure, and hard protective seam 4 is new layer reinforced structure, and it can be the silicon nitride (Si of individual layer
3N
4) or titanium nitride (TiN) sputtering layer, also can be Si
3N
4/ TiN/Si
3N
4Compound sputtering layer or composite membrane adopt complex method can further improve the anti-environmental stability of solar energy reflection mirror, and reduce hard protective seam internal stress.
The utility model is in existing solar energy reflection mirror preparation technology, increases the hard protective seam between coat of metal and protective paint, makes the anti-environment of catoptron (corrosion such as sea water resistance, humidity, soda acid) good stability, the hardness height.Solar energy reflection mirror preparation method adopts medium frequency reactive sputtering, and sputtering target material is Titanium (Ti), or semiconductor silicon (Si), and reacting gas is nitrogen (N
2), make interlayer in conjunction with tight and firm.
