Problems solved by technology

Increasing the thickness of the silver layer can reduce the surface resistance of the film layer and improve the thermal insulation performance; however, there is a limit to the increase in the thickness of the two silver layers. Too thick a silver layer will reduce the visible light transmittance of the low-emissivity glass and weaken the glass transmittance. role of light

Embodiment 1

[0035] A high-performance double-silver low-emissivity glass, the film structure from the glass substrate to the outside is: glass substrate / ITO / Ag / NiCr / ITO / Ag / NiCr / ITO / ZrO 2 . Among them, the thickness of the first low surface resistance transparent conductive layer (ITO) is 30nm; the thickness of the first silver layer (Ag) is 12nm; the thickness of the first protective layer (NiCr) is 1.5nm; the second low surface resistance transparent conductive layer The thickness of the first layer (ITO) is 60nm; the thickness of the second silver layer (Ag) is 14nm; the thickness of the second protective layer (NiCr) is 2nm; the thickness of the third low surface resistance transparent conductive layer (ITO) is 40nm; Protective layer (ZrO 2 ) with a thickness of 20nm.

[0036] The steps for preparing the above-mentioned high-performance double-silver low-emissivity glass are as follows:

[0037] (1) Provide a glass substrate, clean it, dry it, and place it in a vacuum sputtering are...

Abstract

The invention relates to a high-performance double-silver-layer low-radiation glass and a preparation method thereof. The high-performance double-ilver-layer low-radiation glass comprises a glass substrate and a first low surface resistance transparent conductive layer, a first silver layer, a first protective layer, a second low surface resistance transparent conductive layer, a second silver layer, a second protective layer, a third low surface resistance transparent conductive layer and a top protective layer which are successively form on the glass substrate. The high-performance double-silver-layer low-radiation glass, on the premise of better transmittance, also has increased heat insulation performance.

Description

technical field [0001] The invention relates to an energy-saving glass, in particular to a high-performance double-silver low-emissivity glass and a preparation method thereof. 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. In the low-e glass family, double-silver low-e glass with excellent energy-saving performance has been widely used. [0003] Low-emissivity glass is formed by depositing a low-emissivity film on the surface of ordinary glass. Since the low-emissivity film contains a silver layer with excellent electrical conductivity, the surface resistance of the low-emission film layer is low, and the emissivity ε is related to the surface resistance R □ Satisfies the formula: ε=0.0106R □ , the lower the surfac...
