Description
The present invention relates to comprise the multiple glazing plate (vitrage multiple) of at least one an outer sheet glass and an interior sheet glass, these sheet glass (vitre) are separated by at least one insulation layer (lame siolante), and described outer sheet glass has the inner face that contacts with this insulation layer.
Therefore, the present invention relates to the sheet glass field, as the glass of building plate, they are used for closed window, and therefore guarantee space outerpace and internal space are separated, and can also make at least a portion light simultaneously, and visible daylight passes through especially.
Therefore, term " multiple glazing plate " expression in the present invention is a kind of sheet glass that comprises at least two sheet glass (outer sheet glass and interior sheet glass) insulation layer, this insulation layer is for example by gas cloud, air vacuum space, perhaps layer of inert is formed, it is placed between these two sheet glass, contacts with the inner face of outer sheet glass at least.
Conduct by conduction under the situation of heat at it, this layer is to be called " insulating " only considerably lessly.Therefore not solid or fluent material.
If this insulation layer also contacts with the inner face of interior sheet glass, therefore this multiple glazing plate constitutes double glazing unit.
Yet also possible is that this insulation layer itself can also be divided into two independent sectors by sheet glass.At this moment this sheet glass is the triplex glass plate.
Described sheet glass on meaning of the present invention is monolithic glass sheet (vitresmonolithiques) normally, they each all by the solid material thin slice, glass flake, even plastic tab especially constitutes.They can also be the compound glass sheets that is made of several glass flakes, and wherein two glass flakes are separated by plastic tab, to form the lamination sheet glass.
In order to produce sheet glass of the present invention, also around sheet glass, provide peripheral frame, be used between these sheet glass, keeping this insulation layer at least.This framework can also help the global stiffness of this sheet glass.
Know the production method of not having the multiple glazing plate that strengthens heat-blocking action by prior art.In this case, because it greatly reduces thermal conduction, this insulation layer has the effect that prevents to transmit energy between two terminal sheet glass.In addition, the convection current in this insulation layer also greatly is lowered.
Yet, in order to reduce sun heat radiation, near-infrared radiation is penetrated into inside especially, those skilled in the art know production so-called " day light guide " multiple glazing plate, its outer sheet glass is providing stack of thin on the face of insulation layer, it can allow most of visible light pass, and stops these near infrared lights (face 1 is the face of the outer sheet glass that contacts with the outside) in face 2 parts of sheet glass.
Those skilled in the art know two class day light guide (CS) sheet glass: absorb CS sheet glass and reflection CS sheet glass.
The subject matter that these absorptions CS sheet glass brings is this fact, and promptly this sheet glass is isotropically launched it to this insulation layer at a part of thermal infrared energy (the about 10 μ m of wavelength) that face 2 absorbs again.
This problem is more serious in the situation of triplex glass plate, because may heat this layer by the outside to the emission again of first insulation layer, and impels and is going up condensation towards the face (it is colder) of inside.
The heat of these sheet glass is Emission Factor q again
i(facteur de r é é mission thermique) therefore absorbs the common height than reflection CS sheet glass of day light factor (facteur solaire) of CS sheet glass, even its energy transmission is the same with the latter good than reflection CS sheet glass height.
The objective of the invention is to absorb the outer sheet glass of CS but have lower heat radiation factor q again by proposing a kind of the adding
iAnd therefore have lower day light factor and therefore bigger optionally multiple glazing plate, alleviate the defective of prior art.
Another main purpose of the present invention is to realize this result in a kind of simply and not too expensive mode.
Therefore, the most widely on the scope, the present invention relates to sheet glass according to claim 1 at it.This sheet glass comprises at least one outer sheet glass and interior sheet glass, these sheet glass by at least one insulation layer separately, described outer sheet glass has the inner face that contacts with insulation layer, it is characterized in that described outer sheet glass comprises an absorption day light guide base material (substrat de
Solaire parabsorption), the low radiation stack of thin (empilement de couches minces bas-é missif) of the described inner-surface coated lid of the outer sheet glass that contacts with this insulation layer (lame isolante).
So, be positioned at the low radiation stack of thin (in fact in the position (dans une position de fait plus à l ' int é rieur que les moyens absorbants) than the more inner portion of described absorption means) on the outer glass sheet surface that contacts with this insulation layer, restriction absorbs day absorption means of light guide base material and also therefore launches to the heat of inside to this insulation layer again.
This minimizing of emission again causes heat Emission Factor q again
iReduction, and thereby the day light factor of sheet glass also reduce, therefore because than reflection CS sheet glass lower production cost, the selectivity of sheet glass increases.
The selectivity that obtains even can be better than the selectivity that obtains usually with reflection CS sheet glass, and transmitance correspondingly reduces.

The painted absorption day light guide base material that title " H-Green " expression is sold by SAINT-GOBAIN CLASS company, it is especially with the base material that acts on the glass of building plate.
In addition, Fig. 7 for example understands this structure of above-mentioned three embodiment.
In the figure, multiple glazing plate (10) comprises outer sheet glass (20) and interior sheet glass (40), and they are insulated layer (30) separately.Incident daylight is represented with the double-headed arrow in sheet glass left side.
Like this, this sheet glass has four faces, is numbered 1-4 from outside to inside, and insulation layer contacts with 3 with face 2.
Outer sheet glass (20) is made of the absorption day light guide base material PG (22) of mass pigmentation, and this base material has been capped low emission stack of thin (29) PLT on the face 2 within it.
The selectivity that adopts this technical scheme to obtain is better than the selectivity (the 2nd hurdle) of the double glazing unit that absorbs the CS base greatly.
PLT lamination with functional layer of single money base can access is enough to reduce greatly the low emission characteristic that the energy that absorbs the CS base material is launched again.
The light transmission of the 4th hurdle solution is higher, it is not because the low emission of deposition lamination also can be by very big change, because the latter is very neutral (neutre) in the visible spectrum part.This energy transmission mainly limits by absorbing the CS base material.Thereby day light factor and selectivity are also fine, even slightly improve with respect to the sheet glass of the reflection CS lamination that combines SKN-172 (the 3rd hurdle) base, and this reflection CS lamination comprises the metal function layer of two-layer money base.
In addition, the expense beguine according to the technical scheme on the 5th hurdle is more cheap according to the technical scheme on the 3rd hurdle.
Illustrational as Fig. 8, another kind of technical scheme is to use the day light guide base material (22) that is coated with absorbing coating, this coating comprises absorptivity stack of thin (24), comprise the absorptivity stack of thin (24) of the absorptive function layer of one deck metal nitride (as niobium nitride) base at least especially, the lamination of like Cool Lite ST type.In the illustrational structure of institute, this absorptivity stack of thin (24) is deposited on the painted base material of PG class, but it can be deposited on the PLX class transparent substrate fully.
As in Fig. 9 illustrated, another kind of technical scheme is to use the day light guide base material (22) that is coated with absorbing coating, this coating comprises dielectric matrix (26), described matrix has added metal or semiconductor nano sintering metal (nano-cermets m é talliques ousemi-conducteurs), so that can be implemented in the absorption of the very highly selective among the nearly IR, and with the adjustable peak of this material-wavelength (pic ajustable enlongueur d ' onde) by the plasma resonance effect.
Thereby, can for example use sedimentary ITO nanometer metal ceramic in dielectric matrix (nano-cermets d ' ITO), in addition, this matrix preferably with dielectric materials base following cover coating and dielectric materials base on cover coating and surround.
In the structure of Fig. 9 illustrated, comprise that the absorbing coating of dielectric materials (26) is deposited on the painted base material of PG type, but it can be deposited over fully on the PLX type transparent substrate.
As in Figure 10 illustrated, another kind of technical scheme is to use compound outer sheet glass (20), and here it is made of laminated glass, and this laminated glass comprises two glass flakes that separate with middle base material (28).
Here, middle base material (28) is made with PVB, and mass pigmentation.
Therefore, this sheet glass has six faces, numbering 1-6 from outside to inside, and the middle base material (28) of mass pigmentation contacts with 3 with face 2, and insulation layer (30) contacts with 5 with face 4.
Another kind of technical scheme (not illustrating) is to use electrochromic compound outer sheet glass, it is made of laminated glass, this laminated glass comprises two glass flakes that separated by middle base material (28), electrochromic system be inserted in base material and from outside between second sheet glass beginning.
In this case, when electrochromic system was coloring mode, it absorbed a part of incident light, and low emission lamination stops the energy of launching a part of coated absorption again to insulation layer, therefore stoped this energy to be launched to inside again.
The present invention describes by way of example in its previous section.It should be understood that those skilled in the art can carry out various different modification of the present invention, and can therefore not exceed scope of patent protection as being defined by the claims.
