Description

A kind of double-silver low-emissivity coated glass and preparation method thereof
Technical field
The present invention relates to glass arts more particularly to a kind of double-silver low-emissivity coated glass and preparation method thereof.
Background technology
Low radiation coated glass is using high-tech vacuum magnetic-control sputtering technology, nanometer is plated on large-size glass substrate What the silverskin and multilevel oxide anti-reflection film of grade (1 nanometer=0.000001 millimeter) thickness manufactured.According under Different climate environment Requirement can make a series of product of different models of the visible light transmittance between 40%~80%.With a piece of low The hollow glass that radiation film coating glass and 12 millimeters of another sheet glass interval gas blanket make has magical energy-saving effect, summer (far infrared radiation is also referred to as hot spoke to the far infrared radiation in near-infrared radiation and outdoor environment in its reflection and barrier sunlight Penetrate), keep indoor refrigerant comfortable；It reflected and obstructed the far infrared radiation that room heater is sent out winter, maintained warm interior Temperature.Everything is attributed to the fact that the perfect combination of the high infrared reflection performance of silverskin and the low convection current performance of hollow internal gas.It is low The magical part of radiant glass is, not only keeps good daylighting function, but also effectively stop too as heat-reflecting glass The direct heat radiation of sun, it more difficult to and though can be valuable be to play the effect for stopping heat radiation always at daytime or night.
Preparing low-emissivity coated hollow glass can be largely used to heavy construction glass curtain wall and the glass door and window of residential houses, The public activities place such as perspectivity and the exigent exhibition center of thermal insulation, market can also be used in, can be also used for keeping low The windowpane of the refrigerator-freezer of temperature.
Low radiation coated glass can be made into laminated glass use, and this glass is in addition to having certain blocking sun spoke Outside the function of penetrating, also there is quite outstanding security personnel's performance and sound insulation value.When doubling glass is attacked by external force, toughness is very Good PVB films can promptly absorb energy, and glass fragment is kept completely to stick together, thus it can resist bullet, Earthquake, the injury of typhoon, hail prevent the criminal offence forced open the door, broken window is entered the room.PVB films also play in terms of sound wave is obstructed Important role makes doubling glass product reduce by 30 decibels of ambient noise or more.
Low emissivity (low-e) coated glass has the advantages that through visible ray and reflects infrared ray, so as to significantly It reduces the air conditioning energy consumption of automobile and improves the comfort level of driver and passenger, therefore building as a kind of green product And have the huge market demand above the vehicles.The core material of Silver-based low emissivity coated glass is the silver of one layer or multilayer (Ag) layer, can be saturating so must all have been deposited in the upper and lower of silver-colored (Ag) layer since silver (Ag) layer is easily corroded and aoxidizes Cross the transparent dielectric layer of visible ray；The necessary compactness of these dielectric layers is good, thermal stability is high, enough so as to be provided for silver layer Heat, power and chemoproection.In the dielectric layer of Silver-based low emissivity coated glass, near glass substrate dielectric layer and farthest away from Dielectric layer above the silver layer of glass substrate is especially important to the protection of silver layer, particularly must near the dielectric layer of glass substrate It can must at high temperature obstruct the osmosis of the alkali metal ion and oxygen atom in glass.On the other hand, these media Layer can also play the role of the antireflective to visible ray, be combined together with silver layer and realize that visible ray preferably penetrates and reflection is special Property.
It is offline at present it is low-emission coated can be divided into two kinds of single silver low radiation film, low-radiation film by film layer structure, before the latter's ratio Person has lower radiance E and U value, and general single silver Low-E films are mainly by the silver layer (Ag) for being evenly distributed on middle layer To play the role of reflecting far-infrared thermal radiation, entire thicknesses of layers about 45~75nm；And then completely different, its overall structure phase To more complicated, the silver layer for mainly having more than two layers is evenly distributed between the metal oxide that other shield, film layer In silver layer (Ag) overlap middle layer to be separated by, the thickness of silver-based film layer forms metal layer and insulation about between 5~12nm The cross one another Special Film structure of layer.

Embodiment 5
The obtained products of embodiment 1-4 are tested, the results are shown in table below：
Embodiment 1 2 3 4
Shading coefficient SC 0.260 0.259 0.258 0.254
Light transmittance 75 73 78 72
E values 0.038 0.036 0.032 0.035
G values 0.41 0.45 0.40 0.48
Wherein, E values refer to radiance.Radiance refers to through the ratio between the far infrared of glass and incident far infrared.Spoke Penetrate that rate is smaller, the heat reflected back by film layer is more, and heat insulation is better.(E=0.0129R-6.7-5R2)
G values are solar energy acquisition value (shade coefficients).It is the amount for weighing the total transmitance of solar energy.It southern area will Ask G values more lower better, the higher the better for northern area requirement G values.
