the utility model object is: provide a kind of light transmission rate high, effectively prevent light pollution and can reduce the anti-reflection ultra-thin solar glass of the optical absorption loss of solar energy glass itself.

the technical solution of the utility model is: a kind of anti-reflection ultra-thin solar glass, it is characterized in that, comprise the low iron figured glass of ultrawhite, be coated with one deck nanometer anti-reflection hydrophilic film by Ar coating liquid through first roller coat, later half toughening method on the surface of the low iron figured glass of described ultrawhite, the utility model adopts the low iron figured glass of ultrawhite as solar energy glass substrate, the reflectivity that has reduced to a certain extent light is processed in the making herbs into wool on the low iron figured glass of its ultrawhite surface, the low iron content formula of itself has also significantly reduced the specific absorption of sun power, be coated with again on this basis the antireflecting Ar coating liquid of one deck, the anti-reflection ultra-thin solar glass obtaining after half tempered is processed again, can make it under various angle incident conditions, all there is high sun power transmitance, and reflectivity is low, effectively prevent light pollution, thereby reach higher solar conversion efficiency.

preferably, the thickness of the low iron figured glass of described ultrawhite is less than or equal to 2mm; Thinner than traditional 3.2mm, 4mm solar energy glass, not only its quality is light, reduces production cost, simultaneously owing to having reduced the thickness of glass, thereby reduced the absorption loss of glass itself, strengthened solar light-transmitting ability, the technique of half tempered has been eliminated the possibility of glass self-explosion simultaneously.

preferably, the anti-reflection hydrophilic film of described nanometer is plated on the upper surface of the low iron figured glass of described ultrawhite; Because sunlight is mainly injected from outside, so the anti-reflection hydrophilic film of nanometer is mainly plated on the upper surface of the low iron figured glass of ultrawhite.

the Ar coating liquid that the utility model adopts adopts formula as follows: alcohol 80w%, distilled water 13w%, SiCl ₄ 4w%, KNO ₃ 2w%, MgCl ₂ 0.5w%, CaF ₂ 0.2 ± 0.1w%, HNO30.2 ± 0.1w%, by adopt the Ar coating liquid that forms of this formulated by rolling method coat ultrawhite low iron figured glass upper surface or on, lower surface, at 120 ℃ of temperature, dry, about 4mins, then by after horizontal annealing furnace half tempered, form the anti-reflection ultra-thin solar glass of half tempered, in half tempered process, half tempered temperature is 700 ℃, tempering blast is 0.900MPa, Xu Leng blast is 0.4MPa, be 90s heat-up time, chilling period is 6s, cooling time is 28s, semi-tempered glass surface stress reaches 60MPa, shock resistance can tolerate 1.3 meters of free-fallings of 227g steel ball and impact not broken.

the utility model has the advantages that:

1. the utility model adopts the low iron figured glass of ultrawhite as solar energy glass substrate, and at the antireflecting Ar coating liquid of its surface coated one deck, the anti-reflection ultra-thin solar glass obtaining after half tempered is processed again, can make it under various angle incident conditions, all there is high sun power transmitance, can reach 95%, and reflectivity is low, effectively prevents light pollution, thereby reach higher solar conversion efficiency and reliable resistance to impact shock.

. the utility model adopts the low iron figured glass of ultrawhite of 2mm, itself is thinner than traditional 3.2mm, 4mm solar energy glass, not only its quality is light, reduce production cost, simultaneously owing to having reduced the thickness of glass, thereby reduced the absorption loss of glass itself, strengthened solar light-transmitting ability, the technique of half tempered has been eliminated the possibility of glass self-explosion simultaneously.
