Abstract
The utility model discloses an uvioresistant antireflective coating film layer with a heat insulation effect. The uvioresistant antireflective coating film layer with the heat insulation effect is characterized in that four composite antireflective coating film layers can be coated on common glass. From the surface of common glass, the antireflective coating film layers sequentially comprise a TiO2 or Nb2O5 layer, a first SiO2 layer, a ZnO and Al2O3 alyer, and a second SiO2 layer. The uvioresistant antireflective coating film layer with the heat insulation effect provided by the utility model has the function of reducing the reflectivity of visible lights on the surface of the glass, so that the amount of the visible lights through common glass is enhanced from 90% to 98%. The uvioresistant antireflective coating film layer with the heat insulation effect further has the uvioresistant effect, reduces ultraviolet rays passing through glass, has the insulation effect, and reduces the infrared rays passing through glass.
Description
Technical field
The utility model relates to the coatings on a kind of glass surface, the antireflective coatings of especially a kind of anti-electrostatic uvioresistant and reflective infrared
Background technology
Light has 4% light and is fallen by the surface reflection of glass by simple glass the time, positive and negative two surfaces of glass reflect away 8% light altogether, and light is only had about 90% by the amount of glass.
Glass substrate itself is uvioresistant not, and is also very weak to ultrared reflection.Antireflective coating does not have substantially for anti-ultraviolet at present.
The plating ITO(tin indium oxide that present glass has) coating, have preferably electroconductibility and the transparency, can cut off harmful electron radiation, ultraviolet ray and far infrared rays, but ITO coating does not have the antireflective function, cost is also very high, usually be not used in uvioresistant and subtract ultrared effect, and be mainly used in the touch-screen aspect.
The utility model content
The utility model purpose is: the antireflective coatings that a kind of glass surface is provided, make glass single-sided be reduced to 1% to the reflectivity of light by 4%, behind the two sides plated film of glass, light is increased to about 98% by the amount of glass, when reducing the visible light reflection, increase reaches uvioresistant and anti-infrared function to ultraviolet ray and ultrared reflection and absorption.
The technical solution of the utility model is:

Layer has electroconductibility, and surface resistance is 5 ohm ~ 1 megaohm, and simultaneously to visible transparent, ZnO coating has strong absorption to UV-light (wavelength is less than 380nm), and specific absorption is 50% ~ 90%.
Further, set and accurately control the thickness of each rete, make the reflected light interference effect reach best, thereby reduce the reflectivity of light, when reducing visible reflectance, increase ultraviolet and ultrared reflection.The radiation coefficient of rete is 0.1 ~ 0.5, and is high to ultrared reflection.
Further, outer field the second silicon oxide layer is very hard, and its pencil hardness can reach 7H.Except playing compound action, have protection and anti-scratch concurrently.
The utility model has the advantages that:
1. the utlity model has and reduce visible light in the function of reflection of glass surface rate, make visible light be promoted to 98% by the amount of simple glass by 90%.
. the utility model coating has the uvioresistant effect, can reduce ultraviolet ray and pass through glass.
The utlity model has heat-blocking action, can reduce infrared rays and pass through glass.
The utility model has certain electrostatic-proof function, and cost is lower.
