Problems solved by technology

However, the increase of the film layer increases the interference of light, which is specifically manifested in the inconsistency of the hue of the reflection color of the glass surface when viewed from the side and viewed from the front, and there is a big difference
The reflection color observed from the side is greener or redder or yellowish greener or purpler than the reflection color viewed from the front, and the color cast is more serious. After this kind of glass is installed on the curtain wall, it can be viewed from bottom to top, or viewed from the side. Look, the color is inconsistent, which will affect the visual effect of the building, so it will affect the large-scale promotion of triple-silver low-e glass in curtain wall glass

Abstract

The invention relates to a piece of infrared ray shielding glass with a front surface and a side surface having consistent reflection hues. The infrared ray shielding glass comprises a glass substrate and an infrared ray shielding film structure formed on the surface of the glass substrate, wherein the film structure sequentially comprises a first composite medium layer, a bottom infrared ray shielding layer, a first protective layer, a second composite medium layer, an infrared ray shielding mixing layer, a second protective layer, a third composite dielectric layer, a top infrared ray shielding layer, a third protective layer and a fourth composite dielectric layer from the glass substrate to the outside, wherein the thickness of the bottom infrared ray shielding layer is less than that of the top infrared ray shielding layer, and the thickness of the top infrared ray shielding layer is less than that of the infrared ray shielding mixing layer. The infrared ray shielding glass has an excellent infrared ray shielding performance and also has the advantages that the front surface and the side surface of the glass have the consistent reflection hues.

Description

technical field [0001] The invention relates to an infrared shielding glass, in particular to an infrared shielding glass whose front and side reflective colors are consistent. Background technique [0002] With the implementation of national energy conservation and emission reduction policies and people's awareness of low-carbon environmental protection, energy-saving glass represented by low-emissivity glass is more and more widely used in doors, windows and glass curtain walls. [0003] The functional layer of the existing triple-silver low-emissivity glass is three very thin silver film layers. Because the silver film layer has a high reflectivity to infrared rays, this triple-silver low-emissivity glass has good heat insulation performance. [0004] Generally speaking, in the existing three-silver low-emissivity glass film layer structure, the thickness of the bottom silver layer is smaller than the thickness of the middle silver layer, and the thickness of the middle s...
