Abstract
The invention provides a light-adjusting film, high-camber light-adjustable glass and application thereof. The dimming film comprises two layers of base films, a color-changing film, two electrodes and at least one annular reinforcing layer; wherein: the color-changing film is positioned between the two base films; the annular reinforcing layer is arranged at the edge or the area within the edge of one layer of base film. The invention also provides a high-camber adjustable glass which comprises the dimming film. The invention also provides application of the high-camber adjustable glass as vehicle glass. The dimming film can reduce the possibility of generating wrinkles in a dimming visible area when being applied to glass with large camber. For high camber glass, the possibility of wrinkles generated by the membrane extending into the viewable area can be reduced by adjusting the electrodes or increasing the spacing and stiffness of the stiffening layers.
Description
Technical Field
The invention relates to a dimming film and high-camber dimmable glass, and belongs to the technical field of dimming glass.
Background
Dimming glass has become a trend today, and more automobiles will choose to choose a dimmable glass on a sunroof or side window. Current dimming technology, whether PDLC, EC, SPD or future LC, uses flexible dimming films sandwiched in two layers of glass to form a dimmable glass.
The structure of the dimming film, whether PDLC, EC, SPD or LC dimming, is substantially as shown in fig. 1. The light modulation film is generally of a three-layer structure: and a layer of color-changing substance is sandwiched between two symmetrical PET flexible films with ITO conductive layers. The periphery of the PET flexible film is provided with a circle of electrodes used for conducting electricity, and the electrodes can be conductive silver colloid or conductive copper strips. The electrodes are arranged on the periphery or part of the PET flexible film, as shown in fig. 2, the arrangement mode is mainly based on PDLC, SPD and LC, because the color change speed is high, and the electrodes do not need to be increased to improve the conduction speed.
The existing skylight glass, especially the awning glass, is large in size, has a large arch height which is basically more than 20mm/M, and has a tendency of being flat in the middle and bent at the edges, as shown in fig. 3 and 4.
In both types of color-changing films, the film is flexible PET, and the film is thin (not more than 0.4 mm), so that when the film is glued into bent glass, the film is wrinkled due to the extrusion of the glass. Further, since the most curved points of the glass are all at the edges, the resulting fold shape is such that it extends inward from the edges, and the more the edges are, the shallower the folds are, as shown in fig. 5.

After the completion of the preparation, no wrinkles were generated at all in the dimming visible region of the large camber dimmable glass of example 4, and no bubbles were generated even when the dimming film using the color-changing film as EC film, and there was no risk of glass cracking.
In the present invention, fig. 6 to 10 are schematic views for the structure of the light modulation film, and do not represent the dimensions (especially the ratio between the dimensions) and the relative positions of the respective parts in the actual light modulation film, which are to be completely consistent with the dimensions and the relative positions shown in the drawings.
The technical features of the above embodiments may be arbitrarily combined, and for brevity, all of the possible combinations of the technical features of the above embodiments are not described, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
