Abstract

The invention provides a membranous layer composite structure of toughened low-radiation coated glass with a double-silver composite structure; toughening processing technique can be carried out after coating without influence on quality of products; silicon nitride (Si3N4) + ZnO is used as a composite dielectric layer of a base layer; one or more of tin oxide (SnO2), titanium oxide (TiO2), silicon nitride (Si3N4), and an absorbing layer of niobium oxide (Kb2O5) with ZnO are selected to form a composite dielectric layer of a middle layer; and the thicknesses and membranous components of other layers are reasonably selected, so as to prepare the toughened low-radiation coated glass with the double-silver composite structure which can undergo high-temperature heat processing.

Description

Technical field: [0001] The invention relates to a low-radiation coated glass coated with double silver layers, a composite dielectric layer and an absorption layer, which has high-efficiency sunshade performance and can be tempered. Background technique: [0002] Toughened double-silver coated glass is a film system product composed of multi-layer metal or other compounds including double-silver layer coated on the glass surface with good performance and toughening processability. Due to the double silver layer structure, the product has a high transmittance to visible light while maintaining good heat insulation and sunshade performance, and the long path of the multiple metal compound layers of the composite structure ensures the stability of the silver layer to achieve the after-coating. Tempered reprocessing. [0003] The film layer structure of ordinary double-silver structure low-emissivity glass produced by vacuum magnetron sputtering is generally: glass / base dielec...
