Abstract
The invention discloses an uvioresistant antireflective coated layer with a heat insulating function. The uvioresistant antireflective coated layer with the heat insulating function is characterized in that four layers of compound antireflective coated layers are coated on common glass, wherein the antireflective coated layers from the surface of the common glass to upper side are sequentially as follows: a TiO2 or Nb2O5 layer; a first SiO2 layer; a ZnO and Al2O3 layer; and a second SiO2 layer. The uvioresistant antireflective coated layer with the heat insulating function provided by the invention has the function of reducing the reflectivity of visible lights on the surface of the glass so that the amount of visible lights through the common glass is promoted from 90% to 98%. The uvioresistant antireflective coated layer with the heat insulating function further has the uvioresistant effect, reduces the probability of ultraviolet through the glass, has the heat insulating effect and reduces infrared rays passing through the glass.
Description
Technical field
The present invention relates to the coatings on a kind of glass surface, the antireflective coatings of especially a kind of antistatic uvioresistant and reflective infrared
Background technology
light has 4% light and is reflected away by the surface of glass through simple glass the time, positive and negative two surfaces of glass reflect away 8% light altogether, and light is had only about 90% through the amount of glass.
glass substrate itself is uvioresistant not, to ultrared reflection also very a little less than.At present antireflective coating is used for anti-ultravioletly not having basically.
Plating ITO (tin indium oxide) coating that
present glass has; Have the electric conductivity and the transparency preferably; Can cut off harmful electron radiation, ultraviolet ray and far infrared, 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.
Summary of the invention
the present invention seeks to: the antireflective coatings that a kind of glass surface is provided; Make the glass single face be reduced to 1% by 4% to the reflectivity of light; Behind the two sides plated film of glass, light is increased to about 98% through the amount of glass, when reducing to the visible light reflection; Increase reaches uvioresistant and anti-infrared function to ultraviolet ray and ultrared reflection and absorption.
Technical scheme of the present invention is:
A kind of antireflective coatings is characterized in that, can be on simple glass four layers of compound antireflective coatings of coating, said antireflective coatings from surface of ordinary glass up is successively: TiO

said antireflective coatings utilizes the method for vacuum sputtering to be plated on glass surface; Every layer of coating uses different materials and thickness difference; Make visible light produce the interference of light, play the effect that reduces visible reflectance, improves its transmitance through the reverberation of different coating.(400 ~ 700nm), the reflectivity of antireflective coatings is≤1% in the scope of visible light.
Further, said ZnO and Al

Layer has electric conductivity, and face resistance is 5 ohm ~ 1 megaohm, and simultaneously to visible transparent, ZnO coating has strong absorption to ultraviolet light (wavelength is less than 380nm), and absorptivity is 50% ~ 90%.
are further set and the accurate thickness of each rete of control, make the reverberation interference effect reach best, thereby reduce the reflectivity of light, when reducing visible reflectance, increase ultraviolet ray and ultrared reflection.The radiation coefficient of rete is 0.1 ~ 0.5, and is high to ultrared reflection.
are further again, and outer field second silicon oxide layer is very hard, and its pencil hardness can reach 7H.Except that playing compound action, have protection and anti-scratch concurrently.
Advantage of the present invention is:
1. the present invention have the function of reduction visible light in the reflection of glass surface rate, make visible light be promoted to 98% through the amount of simple glass by 90%.
3. the present invention have heat-blocking action, can reduce infrared ray and pass through glass.
4. the present invention have certain electrostatic-proof function, and cost is lower.
