Abstract

The invention discloses low-reflectivity low-emissivity coated glass and a preparation method thereof, the low-reflectivity low-emissivity coated glass comprises a glass base layer, a functional layer, a protective film layer, an absorption layer, a second dielectric layer and a third dielectric layer, the functional layer is located at one side of the glass base layer; the protective film layer is positioned at one side, far away from the glass base layer, of the functional layer; the absorption layer is positioned between the glass base layer and the functional layer, is used for absorbing sunlight and comprises at least three protective layers; and the second dielectric layer and the third dielectric layer are respectively positioned between the two protective layers. According to the technical scheme, the reflectivity of the low-emissivity coated glass is reduced.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a low-reflectivity low-radiation coated glass and a preparation method thereof. Background technique [0002] With the large-scale application of glass curtain walls in high-rise buildings, low-emissivity coated glass (Low-E glass) that meets the requirements of energy saving and environmental protection is highly respected. Low-emissivity coated glass has good heat insulation performance and sunshade performance, which can not only meet the requirements of indoor lighting, but also block solar radiation from entering the room and reduce the load of indoor air conditioners. However, the reflectivity of low-emissivity coated glass (Low-E glass) is generally high at present, so the specular reflection phenomenon of architectural glass is very serious, making light pollution a new pollution after waste gas, waste water, waste residue and noise pollution. source of environmental pollu...
