multifunctional glass film

Abstract

The invention provides multifunctional glass film which is of multi-film composite structure; the multifunctional glass film comprises a release film, a first glue layer, a first base layer, a second glue layer, a multifunctional layer and a second base layer sequentially, wherein the multifunctional glass film is attached to the surface of glass through the release film; the multifunctional layer includes an anti-dazzling adjusting film layer, a core layer and a protective layer; the anti-dazzling adjusting film layer and the protective layer are distributed on two sides of the core layer, the anti-dazzling adjusting film layer is attached to the second base layer, and the protective layer is attached to the second glue layer; the core layer is composed of at least one group of three metal layers; the anti-dazzling adjusting film layer is composed of at least one first medium layer D1; the protective layer is composed of at least one second medium layer D'1. In addition, the advanced magnetron sputtering deposition method is introduced herein, environment resistance of a film layer system is enhanced, and a richer color system is acquired.

Description

Technical field [0001] The invention relates to the field of one-way see-through technology and heat insulation of glass films, in particular to a multifunctional glass film. Background technique [0002] Generally speaking, the glass of buildings or automobiles has an inevitable demand for energy saving, heat insulation and sun protection. At the same time, in order to protect the privacy of people inside large-scale building curtain walls, home windows and doors, car windows and certain valuable items, it is necessary to achieve a one-way perspective, that is, a single direction (inside to outside) light transmission effect. [0003] In order to achieve the effects of one-way perspective and heat insulation at the same time, in the prior art, a commonly used method is to directly coat the glass with one or more layers of film structure to change the spectral properties of the glass itself, but due to this film The layer is relatively soft, and usually needs to be made into hollo...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve the effect of one-way perspective and heat insulation at the same time, a common method in the prior art is to directly coat the glass with one or more layers of film structure to change the spectral properties of the glass itself, but due to this film The layer is relatively soft, and it usually needs to be made into insulating glass in the later stage, and the cost is relatively high

[0004] Another commonly used method is to directly stick a window film with this function on the glass surface. This method has lower cost and also has functions such as anti-ultraviolet and anti-splash. The perspective effect is poor, and it has no heat insulation ability
