Abstract

The invention discloses low-emissivity coated glass which can be baked to be bent, relates to coated glass, in particular to the low-emissivity coated glass. The invention provides the low-emissivity coated glass and a sandwich heat-protecting glass formed by the low-emissivity coated glass. The low-emissivity coated glass is sequentially provided with a glass sheet, a first dielectric layer, a low-emissivity layer, a second dielectric layer and a protection layer, wherein, in a preferable embodiment, the coated glass is sequentially provided with glass substrate, SiOxNy, NbOx, NiCrOx, ZnSnOx, Ag, NiCrOx, NbOx and SiOxNy membranous layers. A polyvinyl butyral (PVB) layer and a glass sheet are sequentially overlapped outside the protection layer of the low-emissivity coated glass to form the sandwich heat-protecting glass. The visible light transmittance of the sandwich heat-protecting glass is at least 76%, and the solar energy transmittance is equal to or less than 48%; or the visible light transmittance is equal to or more than 70%, and the solar energy transmittance is equal to or less than 43%. The sandwich heat-protecting glass is particularly suitable for being used as the front windshield glass of an automobile.

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...
