Abstract

The invention discloses novel temperable double-silver low-emissivity energy-saving glass. The energy-saving glass comprises a glass sheet and a coating; the coating comprises a first medium layer, afirst medium protection and seed layer, a first functional layer, a second medium layer, a third medium layer, a second medium protection and seed layer, a second functional layer, a second metal protective layer, a fourth medium layer and a third protective layer from the glass sheet to outside in sequence. The energy-saving glass has the advantages of low color deviation before and after tempering, high coating strength, and low color deviation between the front side and the lateral side, and the application of the LOW-E glass in different fields is promoted.

Description

technical field [0001] The invention relates to the field of energy-saving materials, in particular to a novel temperable double-silver low-radiation energy-saving glass. Background technique [0002] Low-emissivity coated glass ("Low-E" glass) is a kind of coated glass with high reflectance to infrared rays with a wavelength of 4.5~25um. This kind of coated glass has high light transmittance to visible light, which ensures indoor lighting, and has high reflectivity to far-infrared light, so as to prevent the glass from absorbing outdoor heat and then generating thermal radiation, which transmits heat into the room and indoor objects. The heat generated is reflected back to achieve the purpose of reducing the heat radiation passing through the glass. This reduces energy consumption for heating and cooling the building. The performance of Low-E glass is mainly measured by visible light transmittance, shading coefficient and selectivity coefficient. Among them, shading coef...
