Problems solved by technology

[0002] There are low-emissivity coated glass coated with double silver layers on the market, but generally the high-transmission glass has a high shading coefficient, while the glass with medium and low transmission can meet the requirements of low shading coefficient but the reflectivity is relatively high, so it has not yet met the requirements at the same time. Double layer silver coated glass with low shading coefficient and low reflectivity

Abstract

The present invention is one kind of coated glass with double silver layer structure and possessing low reflectivity, high shading coefficient and low insolation, and its coating process. The film structure on the glass includes one first dielectric layer, one composite absorption layer, one first silver layer, one first protecting layer, one composite dielectric layer, one second silver layer, one second protecting layer and one second dielectric layer arranged successively on the glass. The glass with the film structure has the advantages of high infrared reflectivity, low surface radiance, high shading performance, medium visible light transmittance, medium visible light reflectivity, etc.

Description

Technical field: [0001] The invention relates to a low-reflection, high-efficiency sunshade and low-radiation coated glass coated with double silver layers, a composite dielectric layer and a composite absorption layer. Background technique: [0002] There are low-emissivity coated glass coated with double silver layers on the market, but generally the high-transmission glass has a high shading coefficient, while the glass with medium and low transmission can meet the requirements of low shading coefficient but the reflectivity is relatively high, so it has not yet met the requirements at the same time. Double silver coated glass with low shading factor and low reflectivity. Invention content: [0003] The purpose of the present invention is to provide a low-reflection and high-shading low-radiation coated glass with a double-silver composite structure and a production process in order to satisfy the double-layer silver coated glass with low shading coefficient and low ref...
