Problems solved by technology

[0005] The one-way see-through window film currently on the market is generally attached to the inner surface of the glass. Although it can achieve the anti-peeping function, the visible light reflectance on the side of the room or inside the car is relatively high. When people look outside through the one-way see-through window film , will produce double image or even mirror effect, the human eyes will feel uncomfortable, and some people may even feel dizzy

Abstract

The invention provides one-way transparent glass film of multi-film composite structure; the one-way transparent glass film comprises a release film, a first glue layer, a first transparent base layer, a second glue layer, a one-way transparent functional layer and a second transparent base layer, wherein the one-way transparent functional layer is composed of a metal layer and a metal compound layer and is attached to the surface of glass through the release film. The one-way transparent glass film has low internal reflectivity, can protect privacy in a room or a car, and can reduce indoor dazzling greatly and improve comfort for human eyes.

Description

technical field [0001] The invention relates to the one-way perspective technical field of glass films, in particular to a one-way see-through glass film. Background technique [0002] Generally speaking, the glass of a building or car can see each other whether you are indoors or outdoors. But in order to protect the privacy of people and specific valuables in large-scale building curtain walls, household door and window glass, car windows, it is necessary to make it reach the light transmission effect of one-way perspective, that is, a single direction (from inside to outside). A common method is to use electronically controlled dimming glass instead of ordinary glass, and control the liquid crystal polymer inside the dimming glass to make it transparent or opaque by closing the voltage switch, which is not only expensive, but also inconvenient to use (manual active control is required) , and can only achieve the purpose of anti-peeping, and lose the meaning of one-way pe...
