Electrical allochroic shading glass

Abstract

The invention discloses electrical allochroic shading glass. A first structure of the electrical allochroic shading glass is characterized by comprising plate glass, and one or more transparent liquid crystal screens, wherein the transparent liquid crystal screens and the plate glass are integrally molded after being bonded by a binding material; and a second character of the electrical allochroic shading glass is characterized by comprising two pieces of glass, polarizing films and a liquid crystal film; the liquid crystal film is arranged between the two pieces of glass; the polarizing film is arranged between each glass and the liquid crystal film; the binding material is formed between the glass and each polarizing film, and between each polarizing film and the liquid crystal film, and the glass, the polarizing films and the liquid crystal film are integrally molded after being bonded at high temperature and high pressure. The invention also discloses electrical allochroic shading hollow glass. The electrical allochroic shading hollow glass is characterized in that one of the two pieces of glasses is the electrical allochroic glass; the electrical allochroic glass comprises the plate glass, and one or more transparent liquid crystal screens, and the transparent liquid crystal screens and the plate glass are integrally molded after being bonded. According to the invention, the light transmittance of the glass can be adjusted, and the electrical allochroic shading glass and the electrical allochroic shading hollow glass are suitable for doors and windows and glass curtain walls of various buildings, and trains, cars, steamships and the like.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to an electrically controlled color-changing sunshade glass. Background technique [0002] At present, in order to improve the indoor lighting effect, a large amount of glass is used in buildings, but the heat transfer coefficient and shading coefficient of the energy-saving glass currently used are both fixed values, which cannot allow the sunlight to penetrate into the room in winter, and the summer The effect of penetrating into the room is less, that is, there is no sunshade function. [0003] In order to prevent the sunlight from radiating indoors in summer, people have installed an external shading system, including outdoor louvers, outdoor roller blinds and awnings. This is to physically block solar radiant heat and sunlight from entering the room through the building envelope. When the sunshade is needed in summer, put it down to prevent sun...

Problems solved by technology

Its disadvantages are: affecting the facade of the building; maintenance and cleaning are difficult; the service life is not long

[0004] Some use hollow louver glass as the door and window glass of buildings. The disadvantages are: the energy saving effect is not as good as the external sunshade, the failure rate is high, the maintenance is inconvenient, and the service life is not long.

Its disadvantage is that it can only adjust the glass from transparent to opaque, but not f
