Problems solved by technology

However, the existing single-silver low-e glass has relatively ordinary performance in terms of performance, shading coefficient, visible light transmittance, and U value (heat transfer coefficient) during use, and cannot meet the market's requirements for high-performance products.
At the same time, the existing low-radiation coating products have large data drift before and after steel, and poor oxidation resistance, which will also cause a decline in product yield

Abstract

A sun-shading type double-silver low-radiation coated glass capable being tempered comprises a glass substrate and a film system plated on the glass substrate. The film system comprises a first dielectric layer, a first protective layer, a first functional layer, a second protective layer, a middle dielectric layer combined layer, a second functional layer, a third protective layer and a top layer dielectric layer combined layer which are sequentially arranged from the glass substrate to the outside, wherein the middle dielectric layer combined layer is formed by a ZnSnO3 layer and a ZnO layer, and the top layer dielectric layer combined layer is formed by a ZnSnO3 layer and a Si3N4 layer. The sun-shading type double-silver low-radiation coated glass can be tempered, data drift degree before and after tempering is small, adhesive force among film layers are strong, and coated products is good in mechanical performance and strong in oxidation resistance, and has the advantages of being sun-shading, low in radiation and the like.

Description

Technical field [0001] The invention relates to the technical field of coating in glass deep processing, in particular to a sun-shading type dual silver steel low-radiation coated glass. Background technique [0002] With the increasing demand for decoration and installation materials in modern construction industry and automobile industries, people's requirements for the quality of glass, which is one of the commonly used materials, are also increasing. Glass is an indispensable part of buildings and cars, and it bears many important functions, including beautifying the appearance of buildings and cars, lighting, and bringing a broad view to the interior. Ordinary glass has a high sunlight transmittance, but has a very low reflectivity to infrared rays. Most of the sunlight enters the room through the glass, thereby heating objects, and the energy in these rooms is lost through the glass in the form of radiation. According to statistics, the heat lost through doors and windows ...
