Description
Technical field
The utility model relates to a kind of coated glass, specifically refers to a kind of Low-E coated glass.
Background technology
Glass is important material of construction, and along with to the improving constantly of decorating building requirement, the usage quantity of glass in building trade also constantly increases.Yet current people, when selecting the glass door and window of buildings, except considering its aesthetics and external appearance characteristic, more focus on its heat control, refrigeration cost and inner sunlight and project the problems such as comfortable balance.This just makes the upstart in coated glass family---and Low-E glass is shown one's talent, and becomes the focus that people pay close attention to.The thermosteresis of outer windowpane is the major portion of building energy consumption, accounts for more than 50% of building energy consumption.Relevant research data shows, the heat transfer of interior surfaces of glass be take radiation as main, accounts for 58%, this means and will reduce from the performance that changes glass the loss of heat energy, and effective means is the radiation that suppresses its internal surface.The radiant ratio of common float glass, up to 0.84, be take silver after basic low radiation film when plating one deck, and its radiant ratio can be down to below 0.15.Therefore, with Low-E glass manufacture building window, can greatly reduce the indoor heat that causes because of radiation to outdoor transmission, reach desirable energy-saving effect.
Another remarkable benefit that the reduction of indoor calorific loss brings is environmental protection.Cold season, the CO caused because of constructure heating
2, SO
2discharge Deng obnoxious flavour is important source of pollution.If use Low-E glass, due to the reduction of thermosteresis, can significantly reduce the fuel consumed because of heating, thereby reduce the discharge of obnoxious flavour.
Low-E glass has high transmittance to visible ray in sunlight, can reach more than 80%, and reflectivity is very low, and this makes it compare with traditional coated glass, and optical property is greatly taken on a new look.From outdoor, watch, outward appearance is more transparent, clear, has both guaranteed the daylighting that buildings is good, has avoided again the light pollution phenomenon that large-area glass curtain wall, double glazing door and window luminous reflectance cause in the past, builds more soft, comfortable luminous environment.
The composite film coating of existing Low-E glass generally comprises dielectric layer, functional layer and blocking layer, and the utility model patent that for example patent No. is 201020579779.4 discloses the silver-colored Low-E coated glass of a kind of list, and its dielectric layer is TiO
2, complete processing is more complicated, rete is thin and the thermal treatment resistance is poor.In addition, its composite film coating is more fragile, when cleaning or wiping, easily on surface, causes scratch.
Summary of the invention
The utility model in view of the foregoing defects the prior art has, provides the Low-E that a kind of transmittance is high, radioprotective is effective coated glass.
The utility model is by the following technical solutions:
The Low-E coated glass, comprise glass substrate and the plating radioprotective composite film on glass substrate, and described radioprotective composite film comprises the first dielectric layer, the first blocking layer, functional layer, the second blocking layer and the second dielectric layer from inside to outside successively; Dielectric layer is Si
