Description

Radiation coated glass capable of being toughened
Technical field
The utility model relates to a kind of coated glass, particularly relates to a kind of radiation coated glass capable of being toughened.
Background technology
Low radiation coated glass also claims Low-E glass, is at the high-quality Float Glass Surface, plates several layers low radiative materials and other metal compound film and forms.Low radiation coated glass has following characteristics: extremely low emissivity, high far infrared (heat radiation) reflectivity can stop after the glass heat absorption heats up and outwards dispel the heat from face with forms of radiation, also can directly reflect far-infrared thermal radiation.Above two characteristics of LOW-E film match with the iris action of double glazing to the convection of heat conduction, have just consisted of the extremely low LOW-E double glazing of U value.But its trap heat to a cold end transmission, stops that indoor heat rushes down to outdoor from an end of heat winter, indoor heat can be remained on indoorly, plays energy-conservation effect; And stop summer in the outdoor thermal radiation inlet chamber, play good heat-blocking action, be present optimal glazing material.
Low radiation coated glass mainly contains two kinds of production methods at present: one) online high temperature pyrolysis sedimentation: finish in float glass process for cooling process, liquid metal or metal-powder are directly injected on the hot glass surface, cooling along with glass, metallic diaphragm becomes the part of glass, and this rete is sturdy and durable.This plated film mode because of with glass processing procedure line, be commonly referred to as on-line coating, though but the low emissivity glass that this method is produced has the hot bending tempering, needn't under hollow state, use, can standing storage, but its thermal property, thermal insulation effect are poor, if want to improve its thermal property by increasing thickness, its transparency is with regard to non-constant.Two) off-line vacuum magnetic-control sputtering method: on glass with vacuum magnetic-control sputtering mode sputter multiple layer metal or pottery magnetic (oxidized metal) film at raw sheet, because of its not with glass processing procedure line, so be called off-line coated, the low radiation coated glass of this kind method explained hereafter, need one deck fine silver film as functional membrane, the fine silver film is between two layers of metal oxide film, metal oxide film provides protection to the fine silver film, and as the middle layer between the rete, the effect of adjusting coated glass color and antireflection increase transmissivity is arranged, it has following properties: 1) near the natural primary color of glass, (visible light wave range of 380nm~780nm) has high perspective rate, and reason glass does not produce serious anti-dazzle public hazards to the height reflection of visible light to wavelength; 2) visible light penetrates indoor manyly in the sunlight, and color nature, daylighting are good, reduce the use of indoor lamp, save the energy; 3) to infrared ray have higher reflectivity (wavelength 780nm~3000nm),, almost be total reflection especially to long wavelength's infrared rays (more than the wavelength 3000nm), a large amount of thermals source capable of blocking enter, and make indoorly to feel nice and cool, reach effect cool in summer and warm in winter; Being suitable for high-grade curtain buildings uses.
But because the consideration of security, above-mentioned low radiation coated glass often will carry out tempering to be handled, if carry out tempering behind the plated film again, because the effect of high temperature (more than 680 ℃), make coatings very easily oxidized and burn out, cause the function of low radiation coated glass to completely lose.
The utility model content
Technical problem to be solved in the utility model provides a kind of radiation coated glass capable of being toughened, still can keep high performance nature behind the tempering.
The technical scheme that the utility model technical solution problem adopts is: radiation coated glass capable of being toughened; comprise glass substrate; also comprise according to this antireflection rete, metal separating film layer, antireflection rete on glass substrate, block infrared ray rete, metal separating film layer and protect overall rete, described antireflection rete is Si 3N 4Or Si 3N 4+ TiO 2Described metal separating film layer is the NiCr alloy; Described antireflection rete is ZAO ceramic target; The described infrared ray rete that blocks is metal A g; Described metal separating film layer is the NiCr alloy; The overall rete of described protection is Si 3N 4, SnO 2+ Si 3N 4Or TiO 2+ Si 3N 4
The beneficial effects of the utility model are: because each the rete arrangement on the radiation coated glass capable of being toughened of the present utility model is reasonable, can carries out tempering or heat treatment, and still can keep high performance nature after carrying out tempering or heat treatment; Have the heat-insulating and energy-saving performance the same with two silver-colored LOW-E; Product can store 4-6 month can oxidation; Have the nature color, have high permeability at visible light wave range, can not produce serious anti-dazzle public hazards.
