[0003] Chinese patent 200620004861.8 discloses a heat-reflecting laminated glass. This patent describes that the heat-reflecting function of laminated glass can be realized by changing the structure and material of polyvinyl butyral (Polyvinyl Butyral, PVB), because ordinary laminated glass has no heat reflective or insulating
[0011] However, some of the temperable low-emissivity coated glasses mentioned above cannot withstand the baking and bending process, and the low-emissivity performance will decrease after baking and bending, and / or the transmittance will change; the visible light transmittance of some film structures It cannot meet the requirements of automobile glass, especially the front windshield glass; so these temperable coated glass products cannot be used to make laminated glass, especially the car front windshield glass

Key performance indicators of the glass after being bent do not change. The glass has low emission. Visible light transmittance of laminated glass composed of the bendable low-emission coated glass is above 76%, and solar transmittance thereof is less than 48%; or the visible light transmittance is above 70% and the solar transmittance is less than 43%. The glass is suitable for the windshield glass of an automobile.

Description

technical field [0001] The invention relates to a coated glass, in particular to a bakeable low-radiation coated glass. Background technique [0002] Ordinary glass has no heat insulation function, but glass can achieve heat insulation function through different technical means. [0003] Chinese patent 200620004861.8 discloses a heat-reflecting laminated glass. This patent describes that the heat-reflecting function of laminated glass can be achieved by changing the structure and material of polyvinyl butyral (Polyvinyl Butyral, PVB), because ordinary laminated glass has no heat reflective or insulating properties. 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 the PVB film layer and the heat reflection film layer laminated with it. , the heat reflective film layer is composed of an ordered arrangement of multip...
