Tri-silver low-E (low emissivity) glass

Abstract

The invention discloses a tri-silver low-E (low emissivity) glass, which comprises a glass substrate. Twelve film layers are compounded on a compound face of the glass substrate adjacently and sequentially from inside to outside. The first film layer is the innermost SiAlOx layer, the second film layer is a SnO layer, a third film layer is a Ag layer, the fourth layer is a ZnO layer, the fifth layer is a SnO layer, the sixth layer is a Ag layer, the seventh layer is a SnO layer, the eighth layer is a NiCr layer, the ninth layer is a Ag layer, the tenth layer is a ZnO layer, the eleventh layer is a TiO2 layer, and the twelfth layer is the outermost AlSiOx layer. The tri-silver low-E glass has the advantages that firstly, the emissivity is high; secondly, visible light transmittance is high; thirdly, color uniformity of the multiple film layers is high; fourthly, the tri-silver low-E glass is stable in performance, and parameters of optical indicatrix, emissivity and the like can be kept stable constantly; and fifthly, the tri-silver low-E glass is long in storage time and remote processing of the tri-silver low-E glass can be realized.

Description

【Technical field】 [0001] The invention relates to a coated glass, in particular to a triple-silver LOW-E glass. 【Background technique】 [0002] Glass is an indispensable part of buildings and cars, and it undertakes many important functions, including beautifying the appearance of buildings and cars, lighting and bringing open views to the interior. However, the sunlight transmittance of ordinary coated glass is average, and the infrared reflectivity is very low. Most of the sunlight enters the room through the glass, thereby heating the objects, and the energy of these indoor objects will be lost through the glass in the form of radiation. Moreover, ordinary coated glass has high radiation rate, low transmittance, poor multilayer film color uniformity, unstable performance, and short storage time. [0003] For this reason, the inventor has designed this patent, to overcome the problems referred to above. 【Content of invention】 [0004] The purpose of the present inventi...

Problems solved by technology

However, the sunlight transmittance of ordinary coated glass is average, and the infrared reflectivity is very low. Most of the sunlight enters the room through the glass, thereby heating the objects, and the energy of these indoor objects will be lost through the glass in the form of radiation.

Moreover, ordinary coated glass has high emissivity, low transmittance, poor uniformity of multilayer film color, unstable performance, and short storage time.
