[0059] A second aspect of the present invention provides a method for preparing a dimming component in an embodiment, which is a method for preparing the dimming component in the above-mentioned embodiment, including the following steps:

[0060] Step S110: Laminate the first light-transmitting plate, the first adhesive layer and the light-adjusting film in sequence, and then perform lamination.

[0061] Wherein, the material of the first adhesive layer is non-liquid optical glue before preparing the dimming component. For example, before preparing the dimming component, the material of the first adhesive layer may be solid or solidified optical adhesive OCA, or may be polymer adhesive. In one embodiment, the material of the first adhesive layer is selected from one of PVB and EVA before preparing the light-adjusting component, and the edge of the light-adjusting film is opposite to the first light-transmitting plate and the inside of the first adhesive layer. shrink.

Embodiment 1

[0088] see figure 2 The present embodiment provides a dimming component, specifically a dimming glass 100, the dimming glass 100 includes: a first light-transmitting plate 110, a first adhesive layer 120, a dimming film 130, a second light-transmitting plate 110, a first adhesive layer 120, a dimming film 130, a second The adhesive layer 140 and the second light-transmitting plate 150 . The first light-transmitting plate 110 and the second light-transmitting plate 150 are both hyperbolic glass (the main curvature is: 2293-4900 mm, the secondary curvature is 4887-475778 mm, and the thickness is 2.1 mm). The first adhesive layer 120 is a PVB film with a thickness of 0.38 mm. Before preparing the dimming component, the material of the second adhesive layer 140 is liquid optical glue (specifically, US108 liquid optical glue), and the thickness is 0.4 mm. The dimming film 130 is an LC dimming film. The light-adjusting film 130 and the second adhesive layer 140 are retracted rel...

Abstract

The invention relates to a dimming assembly, a preparation method of the dimming assembly and a vehicle. The dimming assembly comprises a first light-transmitting plate, a first bonding layer, a dimming film, a second bonding layer and a second light-transmitting plate which are sequentially arranged in a stacked mode. The first light-transmitting plate, the first bonding layer and the dimming film can be bonded through a lamination process; the second bonding layer is formed by curing liquid optical cement; the edges of the dimming film and the second bonding layer are shrunk inwards relative to the first bonding layer; the dimming assembly further comprises a sealing component, and the sealing component is located between the first bonding layer and the second light-transmitting plate and makes contact with the dimming film and the edge of the second bonding layer. The dimming assembly is good in appearance and has no Mura phenomenon.

Description

technical field [0001] The present invention relates to the field of glass, in particular to a dimming component, a preparation method thereof, and a vehicle. Background technique [0002] The dimming glass is a new type of photoelectric glass that combines the dimming film into the middle of two layers of glass, and controls the light-transmitting and opaque states of the glass by controlling whether the current is on or off. The conventional dimming glass includes a first glass substrate, a first adhesive layer, a dimming film, a second adhesive layer and a second glass substrate which are arranged in layers. The dimming film is respectively bonded to the first glass substrate and the second glass substrate through the first adhesive layer and the second adhesive layer. The first adhesive layer and the second adhesive layer of the traditional dimming glass are usually PVB adhesive layers or EVA adhesive layers, which are prepared by a lamination process. The appearance of...
