Abstract

A bake-bent low-radiation coated glass relates to coated glass, in particular to low-radiation coated glass. The invention provides a low-radiation coated glass and an interlayer thermal-insulation glass composed of the low-radiation coated glass, wherein the film structure of the low-radiation coated glass comprises a glass plate, a first dielectric layer, a low-radiation layer, a second dielectric layer, and a protective layer, wherein the film structure of one embodiment comprises a glass substrate SiOx / SiOxNy / SnOx / NiCrOx / ZnSnOx / Ag / NiCrOx / SnOx / SiOxNy film from inner to outer at the glass plate, the low-radiation coated glass, PVB (polyvinyl butyral) and another glass plate are layered to form an interlayer thermal-insulation glass which visible light transmission is more than 76% and solar energy transmission is lower than 53%, therefore, the interlayer thermal-insulation glass is particularly applied on vehicle front shield glass.

Description

【Technical field】 [0001] The invention relates to a coated glass, which is especially suitable for low-radiation coated glass. 【Background technique】 [0002] Ordinary laminated glass is a sandwich structure of glass / PVB film / glass, which has no heat insulation function. However, laminated glass can achieve heat insulation function through different technical means. [0003] Chinese Patent No. 200620004861.8 discloses a heat-reflecting laminated glass, which describes the heat-reflecting function of laminated glass by changing the structure and material of PVB (Polyvinyl Butyral, polyvinyl butyral), because ordinary laminated glass is Not reflective or insulating. Its structure includes the first layer of glass, the second layer of glass, and the PVB functional film layer and the first PVB film layer between the two layers of glass. The PVB functional film layer includes a PVB film layer and a heat-reflecting film laminated with it. Layer, the heat reflective film layer i...
