Problems solved by technology

However, no acrylic resin is used for stabilization
The mixtures described therefore do not have the mechanical stability for glass curtain walls with controllable transparency and are correspondingly unsuitable as components for readily switchable sun protection in construction or shipbuilding

Embodiment 1

[0054] Electrochromic laminated glass was prepared by gluing two ITO-coated glasses made of 5 mm float glass, which were joined along the edges by a 1.5 mm thick acrylic adhesive tape. Prepare 72g GmbH's UV (54g 2-ethylhexyl acrylate, 9g acrylic acid, 7.3g methyl methacrylate, 1.7g tris(2-methoxyethoxy)vinylsilane), 36g propylene carbonate, 36g poly(ethylene diethylene glycol) alcohol) diacrylate (M=700g / mol), 14.4g lithium trifluoromethanesulfonate, 0.2g 2,2-dimethoxy-2-phenylacetophenone and 1.6g ethylenedioxythiophene The mixture was stirred for 30 minutes in the dark. The mixture is filled into the cavity between two 300 mm x 300 mm glass plates through a cannula or funnel, and the edges of the window are subsequently sealed with a two-component resin. Subsequently, one glass was cured for 30 minutes in a UV radiation chamber. By applying a DC voltage of 3.0 V for 1 min, a transparent polyethylenedioxythiophene film was formed on the anode, which turned blue when the...

Embodiment 2

[0056] Electrochromic laminated glass was prepared by gluing two ITO-coated glasses made of 5 mm float glass joined along the edges by a 1.5 mm thick acrylic adhesive tape. Preparation of 25.6 g methyl methacrylate, 22.4 g 1,4-butylene glycol diacrylate, 3.2 g pentaerythritol tetraacrylate, 6.4 g 2-hydroxyethyl methacrylate, 6.4 g methacrylic acid, 48 g ethylene carbonate , 48g poly(ethylene glycol) diacrylate (M=700g / mol), 16g lithium perchlorate, 18.8g 3,4-(2,2-dimethylpropylenedioxy)thiophene (ProDOT- Me 2 ) and 0.28 g of 2,2-dimethoxy-2-phenylacetophenone and stirred for 30 minutes in the dark. The mixture is filled into the cavity between two 300 mm x 300 mm glass plates through a cannula or funnel, and the edges of the window are subsequently sealed with a two-component resin. Subsequently, the glass was cured for 30 minutes in a UV radiation chamber. Transparent poly(proDOT-Me 2 ) film, which turns blue-purple when the voltage is removed. The laminate was decoloriz...

Abstract

The present invention relates to an electrochromic cast resin laminated glass which can be used for sun and glare protection. Such a plate glass structure is manufactured by a particularly simple one-step cast resin method and thus has the necessary mechanical stability to be used in the field of building glazing or of vehicles and ships use.

Description

technical field [0001] The present invention relates to electrochromic cast resin laminated glass which can be used as sun protection and anti-glare. Such glass pane structures are produced in a particularly simple one-step resin casting process and thus have the mechanical stability required in the field of glazing for buildings or glazing for vehicles and ships. Background technique [0002] Both electrochromic devices and cast resin laminated glass involve technologies that have been established for decades. [0003] An electrochromic device usually consists of two parallel-oriented substrates made of glass or plastic material, each provided with a conductive transparent electrode on one side. In a first step, a generally inorganic electrochromic layer is deposited on at least one of the two electrodes by evaporation, sputtering or vapor deposition. Optionally, non-electrochromic redox-active substances can also be applied to the second electrode. Subsequently, the two...
