Description
Technical field
The utility model belongs to the glass technology field, and particularly a kind of laminated glass with multiple film layer, this laminated glass are mainly as windshield.
Background technology
The windshield glass of automobile adopts colourless, transparent toughened glass mostly, reflectivity to sunlight is low, effect of heat insulation is poor, in order to improve this situation, some medium-to-high grade automobiles are brought into use the glass that is laid with functional membrane, wherein the most advanced is the ITO film glass, and ITO is the abbreviation of Indium-Tin-Oxide, and its Chinese is the tin indium oxide alloy.
The advantage of tin indium oxide alloy film is: combines with substrate of glass firmly, and wear-resistant, acid and alkali-resistance, low temperature resistant, long service life has the good function that stops the sunlight middle-ultraviolet lamp and the performance of shielding electromagnetic wave.
But the tin indium oxide alloy film also has following shortcoming:
Blocking capability to the sunlight middle infrared (Mid-IR) is relatively poor, the transmitance height of infrared band, and heat directly passes in the car by infrared emanation, and effect of heat insulation is poor.
In order to improve to ultrared blocking capability, have only the thickness that increases the indium stannum alloy plated film, can significantly reduce visible light transmissivity but so do, cause the blank screen phenomenon.
The utility model content
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of transparent, conduction, heat reflection multiple film layer vehicle glass, its transparency height, reflected infrared, shielding of ultraviolet effectively, can be rapidly under low voltage, heating equably, mist elimination defrosting, melting ice and snow.
For achieving the above object, the utility model is by the following technical solutions:
A kind of transparent, conduction, heat reflection multiple film layer vehicle glass, by a coated glass sheet and one not the coated glass sheet form, be provided with adhesive-layer between these two blocks of sheet glass, it is characterized in that:
Described coated glass sheet is made up of four layers of plated film on the glass substrate and the glass substrate internal surface that is laid in, and these four layers of plated films are tin indium oxide alloy rete, zinc sulphide rete, silver film, zinc sulphide rete from inside to outside successively.
The upper and lower edge of the internal surface of described coated glass sheet is horizontally arranged with upper and lower bus respectively, and this upper and lower bus is connected with upper and lower lead-in wire respectively, and this upper and lower lead-in wire is the diagonal angle and arranges.
Innovative point of the present utility model is as follows:
Adopt multilayer film, reduce the thickness of the first layer ITO film, thereby improve the transmittance of visible light.
Adopt silverskin to come reflected infrared; in each element; silver is best long wave heat energy reflecting material; the shortcoming of silver is that hardness is low; not wear-resisting, easily oxidation and weathering, and firm inadequately with combining of unorganic glass or organic transparent material; therefore must be protected with protective layer, be improved bonding force with transition layer.
The utility model adopts ITO/ZnS/Ag/ZnS four tunics, wherein passes through the transition of zinc sulphide rete between ITO rete and the Ag rete, and the protective layer of Ag rete also is the zinc sulphide rete.
The specific refractory power of ITO rete is about 2, and the specific refractory power of ZnS rete is about 2.3, and both are more approaching, helps improving visible light transmissivity.
Though the Ag rete has been subjected to the protection of ZnS rete, therefore such protection adopts the laminated glass structure not enough, makes the Ag rete be subjected to reliably protecting.
After the thickness of ITO rete reduces, the transmittance of its visible light has increased, but its resistance value also can correspondingly increase, if be connected with LVPS, heating power is low, heat-up rate is slow, but silver has extraordinary conductivity, is one of best electrical conductor, and the face resistance value of whole rete is significantly reduced, just can remedy the problem that resistance value raises behind the ITO rete attenuate, thus under low voltage rapid heating.What deserves to be mentioned is: if the ZnS/Ag/ZnS trilamellar membrane directly is laid on the windshield glass, effect is relatively poor, is difficult to long-time steady operation under 12V voltage, and they are laid on the ITO rete, just can make its stable work.
This product has following advantage:
One. the transparency height: visible light transmissivity is greater than 70%.
Two. conduct electricity very well: the face resistance value is low, and the resistance between the upper and lower bus is about 2 to 4 ohm, uses the automobile low-voltage power supply can realize rapid heating.Under 12V voltage, can raise in the time of 5 minutes about 8 ℃, can raise about 14 ℃ in the time of 18 minutes, and current consumption is very little, working stability is reliable.
Three. heat reflection performance is good: at infrared region very strong light reflective is arranged, reflectivity can transmitance significantly descend sun heat radiation more than 85%.When using, can make heat into the car reduce about 50% as vehicle glass.
Four. intercept ultraviolet ray: high ultraviolet isolating rate is arranged, and the ultraviolet isolating rate is more than 85%.
Five. wear-resisting, anti-corrosion: owing to be the laminated glass structure, each rete is between two blocks of sheet glass, so can not wear and tear and corrode.
