A kind of high-transparency temperable triple-silver low-e glass and preparation method thereof

Abstract

The invention discloses high-transmittance temperable three-silver Low-E glass and a preparation method of same. The glass includes a glass substrate, wherein sixteen film layers are successively laminated onto the top surface of the glass substrate from bottom to top; the first film layer is a Si3N4 layer, the second film layer is a TiO2 layer, the third film layer is a NiCr layer, the fourth film layer is a silver layer, the fifth film layer is an AZO layer, the sixth film layer is a Si3N4 layer, the seventh film layer is a TiO2 layer, the eighth film layer is a NiCr layer, the ninth film layer is a silver layer, the tenth film layer is an AZO layer, the eleventh film layer is a Si3N4 layer, the twelfth film layer is a TiO2 layer, the thirteenth film layer is a NiCr layer, the fourteenthfilm layer is a silver layer, the fifteenth film layer is an AZO layer and the sixteenth film layer is a Si3N4 layer. During preparation, the sixteen film layers are formed successively through sputtering coating via a magnetron sputtering process. The Low-E glass has reasonable structural design, high transmittance, low reflection rate and radiation rate, has good mechanical processability and simple preparation method and is suitable for large-scale extensive application.

Description

technical field [0001] The invention relates to the technical field of thin film glass, in particular to a high-permeability toughened triple-silver Low-E glass and a preparation method thereof. Background technique [0002] Low-E glass, also known as low-emissivity glass, is a multi-layer film system product coated on a high-quality float glass substrate with Ag as the functional layer, including a dielectric layer and other metal layers. Its coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional architectural coated glass. [0003] Divided according to the number of functional layers of silver, Low-E glass can be divided into single silver Low-E glass, double silver Low-E glass and triple silver Low-E glass. With the increase of the number of Ag film layers, the energy-saving e...

AI Technical Summary

Problems solved by technology

[0004] However, due to the generally unreasonable design of the film structure of the three-silver low-E glass, it has a great impact on the transmittance and processability of the Low-E glass, resulting in low sunlight transmittance and reflectance of the three-silver low-E glass. High, low selection coefficient, poor machinability, large color deviation after tempering, etc.
