In another preferred embodiment, the composition of the first middle layer, the second middle layer and third middle layer is each other It is different.

For example, the second middle layer and third middle layer, which can be colourless and the first middle layer, can be the centre of coloring Layer.For example, middle layer can also be different from each other in terms of its additive or plasticizer loading.

It should be appreciated that with regard to the structure and size of the first glass plate, the second glass plate, middle layer and function element, material and excellent For selecting embodiment, it is equally applicable to above in relation to statement made by composite glass according to the present invention according to the present invention Method, vice versa.

It in one embodiment, according to the method for the present invention include by infrared radiation reflecting coating cloth as additional step It sets on the inside of the first middle layer, the second middle layer, the inside of the first glass plate or the second glass plate.

In an embodiment according to the method for the present invention, in the side edge of entire function element or function element At least one is surrounded by sealing material, and wherein sealing material is preferably poor plasticizer or not plasticizer-containing, and especially excellent Selection of land include polyethylene terephthalate (PET) or polyethylene (PE) or by polyethylene terephthalate (PET) or Polyethylene (PE) composition.Sealing material especially prevents the chemical component (such as plasticizer) of thermoplastic interlayer to be diffused into active layer In.Thus the muddiness of the fringe region of function element has been reduced or prevented.

In one embodiment, sealant is adhesive or adhesive tape, especially clear, colorless adhesive or transparent nothing Color adhesive tape.It in this case, according to the method for the present invention further include at least one of the side edge for surrounding function element The step of adhesive disposed or adhesive tape.

In another embodiment, sealant is the plastics squeezed out around the side edge of function element.In such case Under, further include the steps that according to the method for the present invention around function element extrusion plastic.

Sealing material is also configured to one or more barrier films, partially or fully covering function element.This In the case of, two, three, four, or more barrier film can also weld together to and be formed bag, function element completely or It is arranged locally in the bag.It in this case, according to the method for the present invention further include being arranged in second by function element Before on interbed, barrier film is arranged around function element or welds together two, three, four, or more barrier film And bag is formed, then function element is wholly or partly arranged in bag.

In a preferred embodiment of the method according to the invention, the method includes sealing material is fixed on In two middle layers and in the first middle layer.Sealing material is arranged in the second and first middle layer, so that it is in lamination step At least one of the side edge of entire function element or function element is surrounded later.For example, can in the second middle layer cloth Sealing material band, sealing material frame or sealing material film are set, and arranges sealing material band, sealing in the first middle layer Material frame or sealing material film.Then, they can for example with corresponding interlayer adhesion.It is fixed in the first middle layer Sealing material and the sealing material being fixed in the second middle layer be laminated and associated exhaust after it is stacked on top of each other and/or It is fused together in lamination process, so that will not be diffused into from middle layer by the side edge for the functional material that sealing material surrounds Chemicals.

In the case where the composite glass of the prior art, function element is surrounded by the middle layer of frame-like.It will be used for function It is technically complicated that the sealing material of the side edge of energy element, which is fixed in frame-like middle layer,.According to the present invention multiple In the case where combined glass glass plate, function element is not arranged in the third middle layer of frame-like, and is arranged on two full surfaces Between middle layer (the first middle layer and the second middle layer, i.e., the middle layer of two not no void areas).By making first and Two middle layers do not have gap and can more easily arrange and fixing seal material in these middle layers.Therefore, according to this The manufacture of invention includes having in the method for the composite glass of function element of electrically controllable optical property, the edge of function element Sealing can be easier to realize compared with method described in the prior.

The invention also includes use of the composite glass according to the present invention in building or land, water and air transport facility On the way.Here, composite glass preferably acts as glass pane, it is used for example as the glass pane of vehicle, the glass pane or building of building The glass pane of object interior room.Composite glass is particularly preferably used as the top glass or windshield of motor vehicles, especially has The electrically controllable sunshading board realized by function element.
