Double-silver low-emissivity coated glass capable of being subjected to high-temperature heat treatment and preparation method of double-silver low-emissivity coated glass

Abstract

The invention discloses double-silver low-emissivity coated glass capable of being subjected to high-temperature heat treatment. The double-silver low-emissivity coated glass comprises a glass substrate, wherein twenty film layers are composited on a composite surface of the glass substrate from inside to outside sequentially and adjacently; the first film layer which is the innermost layer is an SiO2 layer, the second film layer is an Si3N4 layer, the third film layer is an AZO layer, the fourth film layer is an Ag layer, the fifth film layer is an NiCrOx layer, the sixth film layer is an Si3N4 layer, the seventh film layer is an AZO layer, the eighth film layer is an Ag layer, the ninth film layer is an NiCrOx layer, the tenth film layer is an Si3N4 layer and the eleventh layer which is the outermost film layer is a ZrNx layer. According to the provided double-silver low-emissivity coated glass capable of being subjected to high-temperature heat treatment, the color after heat treatment changes little, the transmittance is high, cracking of the film layers of the glass during high-temperature processing can be prevented, the integrity, uniformity and stability of the glass are kept, and the glass can be better applied to building curtain walls. The invention further provides a preparation method of the double-silver low-emissivity coated glass capable of being subjected to high-temperature heat treatment.

Description

【Technical field】 [0001] The present invention relates to a double-silver low-emissivity coated glass, more specifically a double-silver low-emissivity coated glass capable of high-temperature heat treatment, and also relates to a preparation of a double-silver low-emissivity coated glass capable of high-temperature heat treatment method. 【Background technique】 [0002] Glass plays an important role in contemporary production and life, and coated glass has become a good glass curtain wall material and has been widely used. With the diversity and aesthetics of modern architectural design, the appearance of many curtain walls needs to have curved and arc-shaped designs, but the color of the existing double-silver low-emissivity coated glass changes greatly before and after heat treatment, and the transmittance is relatively low. It is easy to crack and damage and cannot be applied to building curtain walls. 【Content of invention】 [0003] The purpose of the present inventi...
