Abstract

The invention relates to the field of glass technologies, and discloses a glass window and a preparation method thereof. The glass window comprises a first protective layer, a middle layer and a second protective layer which are sequentially arranged, wherein the middle layer comprises a first PVB (polyvinyl butyral) layer, a first transparent conductive layer, a PDLC (polymer dispersed liquid crystal) layer, a second transparent conductive layer and a second PVB layer which are sequentially arranged, wherein the first PVB layer is provided with an anti-ultraviolet agent; the PDLC layer is prepared from liquid crystal molecules and a polymer matrix through mixing, and the polymer matrix is prepared by using a nano titanium dioxide modified epoxy resin matrix; and the second PVB layer is provided with an anti-ultraviolet agent. The PVB has excellent impact resistance; the transparent conductive layer is an ITO (indium tin oxide) layer, and has an anti-infrared function and a heat insulation effect; and titanium dioxide can increase view angles and the light transmittance of each view angle, and can absorb ultraviolet light. In addition, the invention also provides a preparation method of the glass window.

Description

technical field [0001] The invention relates to the technical field of glass window manufacture, in particular to a glass window and a preparation method thereof. Background technique [0002] Existing glass windows are all simple in structure and relatively simple in function. Existing glass windows are divided into categories such as single toughened glass windows, laminated glass windows, vacuum glass windows, and glass window film. Glass window film structure such as figure 1 As shown, the glass film is to add a layer of composite film on the surface of the glass. The composite film is made of multi-layer materials, consisting of anti-wear layer 01, PET (polyethylene terephthalate), safety base layer 02, and metal insulation layer. 03. Composite adhesive 04, UV absorbing layer 05 and other structures, glass window film has the advantages of impact resistance, UV resistance, heat insulation and other aspects. [0003] However, there are many layers of glass film, each l...
