Three-silver coated glass

Abstract

The embodiment of the invention discloses three-silver coated glass. The coated glass comprises a glass substrate, and a first dielectric layer, a first priming layer, a first functional layer, a first metal barrier layer, a second dielectric layer, a second priming layer, a second functional layer, a second metal barrier layer, a third dielectric layer, a third priming layer, a third functional layer, a third metal barrier layer and a fourth dielectric layer which are sequentially formed on the same side face of the glass substrate. The second dielectric layer comprises a second lower sub-dielectric layer, a second middle layer and a second upper sub-dielectric layer which are arranged in sequence, the second lower sub-dielectric layer is adjacent to the first metal barrier layer, and thesecond upper sub-dielectric layer is adjacent to the second priming coat; the third dielectric layer comprises a third lower sub-dielectric layer, a third middle layer and a third upper sub-dielectric layer which are arranged in sequence, the third lower sub-dielectric layer is adjacent to the second metal barrier layer, and the third upper sub-dielectric layer is adjacent to the third priming layer; and the second middle layer and the third middle layer are respectively selected from copper-nickel alloy, copper-titanium alloy, copper-chromium alloy and copper-zinc alloy.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a triple-silver coated glass. 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. However, the optical performance of the existing double-silver low-emissivity glass still has certain deficiencies, so its optical performance needs to be further improved to meet higher requirements. Contents of the invention [0003] In view of the above problems, an embodiment of the present invention provides a triple-silver coated glass to improve its optical performance. [0004] On the one hand, a triple-silver...
