The low radiation glass prepared by the invention has a beautiful appearance of blue glass, suitable natural light transmittance and reflectivity. Most importantly, the low radiation glass prepared by the invention has the potential of remote processing, can undergo film coating first and then undergo cutting and tempering processing, thus greatly improving the production efficiency.
Description
Technical field
The present invention relates to a kind of low emissivity glass, but particularly a kind of blueness tempered and low-radiation energy-saving glass.
Background technology
Low radiation energy-saving glass (LOW-E glass), its production technology is to be coated with multilayer to take the assembly of thin films that silver (Ag) is functional layer on high-quality float glass process substrate.At present, the low radiation energy-saving glass processing mode of off-line is divided into two kinds: a kind of is first by former cutting of float glass process, edging, and then the tempering plated film, makes double glazing.A kind of is direct plated film on former of float glass process, then adopts as required the modes such as cutting, edging tempering to be processed.
Existing technology production outward appearance blue tinted glass, be to add appropriate metallic cobalt (Co) ion to obtain by float glass mostly, but this float glass advantage is the strange land processing, and shortcoming is that energy saving is not so good as low emissivity glass.And reach the glass of outward appearance blueness by the plated film adjustable colors, and its advantage is that energy-efficient performance is good, can obtain the better glass appearance of texture, and shortcoming is to realize strange land processing, and production efficiency is relatively low.And blue float glass is by absorbing other visible ray, can only present blueness through blue light, so it is more blue to see through color ratio.
Summary of the invention
The object of the invention is to overcome blue cobalt glass in prior art and do not there is low radiation energy-saving effect, and the low emissivity glass of existing imitative blue outward appearance is difficult to the defect of strange land processing, and a kind of blue low emissivity glass is provided.But the invention provides a kind of blueness tempered and low-radiation energy-saving glass, it can carry out in strange land the processings such as edging, tempering.
In order to realize the foregoing invention purpose, the invention provides following technical scheme:
A kind of low radiation coated glass; it is characterized in that, this glass film layer structure is followed successively by: glass substrate, ground floor prime coat silicon nitride layer, second layer NI-G layer, the 3rd one functional layer silver layer, the 4th layer of protective layer NI-G layer, layer 5 dielectric layer zinc oxide aluminium lamination, layer 6 antireflection layer titanium oxide layer, layer 7 silicon nitride layer.
Described low radiation coated glass adopts the off-line magnetron sputtering plating to make.
Described ground floor prime coat silicon nitride (SiNx) thickness at 10nm between 50nm,
The thickness of described second layer NI-G (NiCr) at 2nm between 8nm,
The thickness of described the 3rd one functional layer (Ag) layer at 4nm between 9nm,
The thickness range of described the 4th layer of protective layer NI-G (NiCr) at 2nm between 7nm,
The thickness range of described layer 5 dielectric layer zinc oxide aluminum (AZO) at 0nm between 15nm,
Described layer 6 antireflection layer titanium oxide (TiOx) thickness at 5nm between 25nm,
The thickness range of described layer 7 silicon nitride (SiNx) at 15nm between 45nm.
Ground floor bottoming dielectric layer improves the adhesive force of rete effects on surface; Second layer NI-G NiCr, promote the adhesive force of Ag layer in rete, improves the oxidation resistance of Ag layer; The 3rd one functional layer, the Ag layer can reflect away the heat radiation in most of solar energy, plays low radiation energy-saving effect; The 4th layer of protective layer, NI-G NiCr or cadmium Cr layer can defencive function layer Ag layer not by follow-up coating process and the oxidation of the institute of process thereafter, lose effect; Layer 5 dielectric layer zinc oxide aluminum, can starvation and other materials, protects inner rete to avoid corroding, and improving film is the performance of resistance to chemical attack and mechanical friction, can play the effect of adjustable colors simultaneously.The major function of layer 6 antireflection layer titanium oxide is protective film.The layer 7 silicon nitride has very strong anticorrosive, anti-machinery scuffing, the performance of high temperature resistance can be protected inner layer film system.
The low emissivity glass that adopts the said sequence rete to be coated with, regulate thicknesses of layers, can change between rete visible optical transmission, absorption and reflection ratio.During the known different thin-film materials combination of optical principle, after can making visible ray pass through rete, reverberation interferes phenomenon.The inventor finds to select above-mentioned film material inadvertently, carry out in a certain order plated film, in above-mentioned thicknesses of layers scope, regulate the thickness of film, can make the natural daylight of each wavelength period obtain suitable reflection, transmittance, glass shows the outward appearance of the blueness of fashion.
Further, in this scope, regulate each layer thickness of film system, can also further strengthen blue light wave reflection ratio, reduce other wave band reflection of lights, thereby present the blueness of fashion beauty more, possess with former of float glass process in add the similar appearance colour of blue glass that cobalt ions obtains, for the manufacture of the blue low emissivity glass of commercialization provides another kind of solution.The glass that the present invention prepares also has good low radiance, and the outstanding infrared reflection shown as in sunshine strengthens, and it is good that the natural daylight visible light part sees through ratio, with general low emissivity glass, compares and have more excellent energy-saving effect.The more important thing is that low emissivity glass prepared by the present invention possesses the potentiality of strange land processing simultaneously, can first plated film, rear cutting, tempering processing.Solve the strange land processing problems of blue coated low-emissivity glass, improved greatly the production efficiency of blue low emissivity glass.
Regulate the outward appearance reflection by the present invention and present blueness, it is more neutral that it sees through color ratio, more meets the requirement of building Visual Aesthetics.So this invention can realize having the blue outward appearance of better texture, greatly enhance productivity simultaneously, meet different customer demands.
Compared with prior art, beneficial effect of the present invention: the reflectivity R of the low emissivity glass that this invention is manufactured is from 8% to 30%, b* scope from-11 to-20, transmitance from 40% to 65%.Annotate: b*(champac degree, the more negative color of its value is more blue)
