Description

Steel single silver low-emission coated glass

The present invention relates to the field of glass deep processing, and specifically relates to a steel single silver low-emission coated glass.

With the increasing demand for decorative materials in modern buildings, the demand for glass as one of the building materials is increasing. Glass is an integral part of buildings and cars, and it carries many important functions, including beautifying the appearance of buildings and cars, lighting, and giving the interior an open view. However, ordinary glass has a high transmittance of sunlight and a low infrared reflectivity. Most of the sunlight enters the room through the glass, which causes the room temperature to rise. Conversely, when the outdoor temperature is low, the energy in the room is dissipated through the glass in the form of radiation. . According to statistics, the heat lost through doors and windows in buildings accounts for about 50% of the heating or cooling energy consumption of the entire building, while the heat lost through the glass accounts for about 80% of the entire window.

At present, there is a glass coated with a low-emission film on the market, and its heat insulation is greatly improved. Especially, the single-silver low-radiation glass currently used in the market is to exclude the infrared rays in the sunlight and to reflect the secondary radiant heat of the object. The special glass that went back is getting more and more popular. However, in the existing single silver low-emissivity glass, the silver-containing functional layer in the inner layer of the single-silver low-emissivity glass is easily oxidized, and its oxidation causes the film system to lose the low-radiation function, so that it is not like ordinary glass. It has thermal insulation performance; and the single-silver low-emission film on the glass has low adhesion, and it is easy to cause film release under high temperature conditions. Therefore, the existing single-silver low-emission glass has To be further improved.

It can be seen from the above description that the conventional single silver low-emission coated glass has a tendency to cause off The problem of the film, therefore, how to provide an anti-oxidation, high adhesion and temperable steel single-silver low-emission coated glass to enhance the mechanical properties protection, improve the processing resistance, avoid the falling off of the film, that is, become This creative work is to solve one of the important issues.

For the aforementioned problems in the prior art, the creators have been engaged in this industry for many years. The experience, active research and improvement, finally developed and designed the steel single silver low-emission coated glass.

One object of the present invention is to provide a steel single silver low-emission coated glass comprising a glass substrate and a functional film system deposited on the glass substrate, the functional film system comprising a longitudinal direction A first barrier layer, a first dielectric layer, a second barrier layer, a functional silver layer, a third barrier layer and a second dielectric layer are stacked on the glass substrate. In addition, optionally, the first barrier layer, the second barrier layer and the third barrier layer are all nickel-chromium (NiCr) films; optionally, the functional silver layer is doped silver layer or silver element; The doped silver layer is a nickel-doped silver layer; optionally, both the first dielectric layer and the second dielectric layer are tantalum nitride (Si ₃ N ₄ ). Thus, by providing the first barrier layer, the present invention effectively avoids diffusion of sodium ions (Na ⁺ ) in the glass and reduces its influence on the film system; further, by providing the functional film system The second barrier layer and the third barrier layer effectively improve the oxidation resistance and the process resistance of the functional film system, and the mechanical mechanism of the functional film system is strengthened by providing the first dielectric layer and the second dielectric layer The performance protection, in turn, makes the steel single silver low-emission coated glass have the advantages of low radiation and temperability, and is worthy of popularization.
