Abstract

The invention relates to the field of glass coating, in particular to low-eradiation coated glass available for heat treatment and high in visible light transmission and sandwich glass products thereof. A film structure sequentially comprises a glass substrate, a first dielectric layer, an infrared reflecting layer and a second dielectric layer above the glass substrate and is characterized in that the second dielectric layer comprises a second dielectric film made of at least one of ZrO2 and ZrOxNy, a third dielectric film deposited on the second dielectric film, wherein the third dielectric film is made of at least one of metal oxides of Ti, Al, Si, Ta, Hf, Nb, Cr, Ni, Fe, Mo, W, Y and the like, or at least one of metal nitrides or metal nitrogen oxides of Ti, Al, Ta, Nb, Fe, Hf, Ni, Cr and the like. The low-eradiation coated glass has the advantages that the low-eradiation coated glass and the sandwich glass products thereof have high mechanical stability and high-temperature thermal treatment stability.

Description

Technical field: [0001] The invention relates to the field of glass coating, in particular to high visible light transmittance, heat-treatable low-radiation coated glass and its laminated glass products, especially suitable for single silver coated laminated glass on vehicles. Background technique: [0002] Low-emissivity film (low-e film) glass has the advantages of transmitting visible light and reflecting infrared rays. Therefore, as a green product, there is a huge market demand in buildings and vehicles. The core material of the low-emissivity film is one or more layers of silver (9nm to 15nm). Since the silver layer is easily corroded and oxidized, a transparent medium that can transmit visible light must be deposited on the top and bottom of the silver layer. layer; these dielectric layers can protect the silver layer from being damaged during subsequent processing, especially high-temperature heat treatment (such as tempering and baking forming); in addition, the die...
