Low-radiation temperable double-silver LOW-E glass

Abstract

The invention discloses low-radiation temperable double-silver LOW-E glass, which comprises a glass substrate, wherein nine film layers are adjacently compounded in sequence on the composite surface of the glass substrate from inside to outside. The low-radiation temperable double-silver LOW-E glass is characterized in that: a first film layer, i.e., an innermost layer is an Si3N4 layer; a second layer is a TiO2 layer; a third layer is a ZnAlOx layer; a fourth layer is an Ag layer; a fifth layer is a TiO2 layer; a sixth layer is a ZnAlOx layer; a seventh layer is an Ag layer; an eighth layer is an NiCrOx layer; and a ninth layer is an Si3N4 layer. The low-radiation temperable double-silver LOW-E glass has the advantages of low radiation rate which is less than or equal to 0.03, good energy saving effect, lower shading coefficient in comparison to the same type of product with the same penetration rate, avoidance of the situation of damaging the film layers when the temperature is 700 DEG C in maximum in a tempering heating process, small color difference after tempering and high film layer uniformity.

Description

【Technical field】 [0001] The invention relates to a coated glass, in particular to a low-radiation temperable double-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 emissivity and poor energy-saving effect, while the existing double-silver low-emissivity (LOW-E) coated glass can be tempered very little, and the film layer is prone to damage after tempering and heating. Layer uniformity is poor. [0003] For this reason, the inventor ...
