Embodiment 1

[0035] The embodiment 1 is used to make the dimming glass of the present invention.

[0036] (1) A polymer-dispersed liquid crystal layer is coated between two conductive layers, and then cured to produce a polymer-dispersed liquid crystal laminate. Coating conductive silver paste on one end surface of the two conductive layers, attaching two copper foils to the two conductive layers respectively, and connecting one lead wire from the copper foil. Wherein, the polymer-dispersed liquid crystal laminate is produced according to the method of Example 1 of CN101017304A, and the two conductive layers are polycarbonate with indium tin oxide conductive film on the surface.

[0037] (2) Provide a piece of clean curved glass, cut a piece of adhesive layer (EVA) into the same size of curved glass 10, and place it on the bottom layer; the laminate obtained in step (1) is cut into the shape of curved glass, surrounded by Slightly smaller, keep the width of 1.0cm from the edge of the glas...

Abstract

The invention provides dimming glass and a manufacturing method thereof. The dimming glass comprises glass, a first adhesive layer, a first conducting layer, a polymer dispersed liquid crystal layer, a second conducting layer, a second adhesive layer and a hard film layer which are orderly stacked. In the dimming glass provided by the invention, the polymer dispersed liquid crystal layer is clamped between the glass and the hard film layer, only one piece of glass is required instead of two pieces of glass, and the requirements on the surface evenness of the glass are not high. In a laminating process, the hard film layer is matched with the glass. Compared with the dimming glass which uses two pieces of glass, the dimming glass of the invention decreases the technological operation difficulty. Furthermore, the dimming glass provided by the invention has small change on the thickness of the glass and can be used together with universal glass. When the dimming glass is applied to the window of an automobile, the dimming glass has the advantages of basically ignored change of a vehicle door structure, no influence on lifting, good stability, effective prevention of ultraviolet and long service life.

Description

technical field [0001] The invention relates to a dimming glass and a manufacturing method thereof. Background technique [0002] Polymer dispersed liquid crystals (Polymer dispersed liquid crystals, PDLC) film is an optoelectronic composite material containing a mixture of polymer and liquid crystal materials. The PDLC film can be changed from opaque to transparent by applying an electric field, so people sandwich the PDLC film between two pieces of glass to make dimming glass. [0003] At present, most dimming glasses are used in buildings, and are also used in curved glass-related devices. For example, CN201097031Y discloses a safety laminated smart liquid crystal side windshield dimming glass for vehicles, which includes a layer of liquid crystal material, and Two pieces of side windshield glass for sandwiching the liquid crystal material layer and matching the shape of the side window of the car. [0004] The existing dimming glass sandwiches a layer of liquid crystal...
