Environment-friendly low-emissivity glass and preparation method thereof

Abstract

The invention discloses an environment-friendly low-emissivity glass and a preparation method thereof. The environment-friendly low-emission glass comprises from bottom to top: a substrate layer, a first transition layer, a tin oxide layer doped with fluorine and antimony, a seed layer, and a functional layer , a toning layer, a second transition layer, a barrier layer and a protective layer, wherein the seed layer is a metal Cu layer, the thickness of the seed layer is 5-10nm, the functional layer is a metal Ag layer, and the thickness of the functional layer is 5-10nm, The toning layer is a metal Pd layer, the thickness of the toning layer is 3-8nm, the second transition layer is a metal Ti layer, the thickness of the second transition layer is 3-6nm, and the thickness of the tin oxide layer doped with fluorine antimony is 5nm. -10nm. The environment-friendly low-emissivity glass of the present invention has a beautiful appearance, and at the same time ensures high low-emission performance and high visible light transmittance.

Description

technical field [0001] The invention relates to the technical field of low-emissivity glass, in particular to an environment-friendly low-emission glass and a preparation method thereof. Background technique [0002] In some spaces where human beings often move and live, such as housing, automobiles, airplanes and refrigerated cabinets, it is required to have certain functions of heat preservation, heat insulation and lighting to meet the needs of human production and life. Glass is the most commonly used and most suitable transparent lighting material, but the thermal insulation effect of ordinary flat glass is not ideal, and cannot meet the needs of human production and life. On the other hand, with the continuous improvement of human aesthetics in architecture, large-area lighting glass has been widely used in various high-rise or landmark buildings, but it cannot be perfectly combined with modern architectural concepts such as building energy saving and reducing light po...

AI Technical Summary

Problems solved by technology

However, there are still some problems with low-e glass in the prior art. Due to the defects in the design of the film layer structure, many low-e glass reflect blue or reddish light at present, which makes the appearance of these low-e glass used in glass curtain walls poor , while reflecting light of this color will cause light pollution

Usually, a toning layer is added to the existing glass film layer, but the addition of the toning layer will inevitably lead to a decrease in the transmittance of the glass. How to ensure that the color of the glass is beautiful and the transmittance is high is a difficult problem in the existing technology
