Problems solved by technology

[0003] The current low-emissivity coated glass with double-silver composite structure on the market can not show the effect of neutral color at the same time when the reflection color is guaranteed to be neutral. When observing the outdoor situation from indoors, it often shows a faint green or yellow color.

Embodiment Construction

[0024] The present invention uses flat glass double-end continuous coating machine for production, wherein a preferred process scheme uses 6 AC double targets, 6 DC single targets, and a total of 12 target positions for production to produce the neutral glass of the present invention. Low-emissivity coated glass with double-silver composite structure. The process parameters and target positions are listed as follows:

[0025]

[0026]

[0027] The optical properties of the glass produced with the above process parameters are as follows:

[0028] Glass visible light transmittance T=66%

[0029] Visible light glass surface reflectance = 10%

[0030] Visible light glass surface reflection color coordinate a* value = -1

[0031] Color coordinate b*value = -6.5

[0032] Visible light transmission color coordinate a* value = -0.8

[0033] Color coordinate b*value = 1.2

[0034] The emissivity of glass ε=0.040.

[0035] The present invention make...

Abstract

The invention provides neutral-color low-radiation film plated glass with a double-silver compound structure and a plating process. An outward structure layer of a glass substrate is sequentially formed by a glass / dielectric medium layer (1) / a compound absorbing layer (1) / a copper alloy layer (1) / a silver layer (1) / a protective layer (1) / a compound dielectric medium layer (1) / a silver layer (2) / a protective layer (2) / a dielectric medium layer (2); and a vacuum magnetron sputtering film plating process is adopted and has the advantages that one layer of the copper alloy layer is additionally arranged in the previous compound structure and the penetrating color is neutral. Due to the properties of the copper alloy and the silver greatly, the emission rate of the glass to far infrared rays is increased, namely the low-radiation performance is realized.

Description

technical field [0001] The invention relates to a low-radiation coated glass with a neutral color double-silver composite structure and its technology [0002] In particular, it relates to a low-emissivity coated glass with a double-silver composite structure coated with a metal copper coating. Background technique [0003] The current low-emissivity coated glass with double-silver composite structure on the market can not show the effect of neutral color at the same time when the reflection color is guaranteed to be neutral. When observing the outdoor situation from indoors, it often shows a faint green or yellow color. . It is mainly caused by the light interference of the multi-layer composite structure of this double-silver product. Contents of the invention [0004] The purpose of the present invention is to provide a low-emissivity coated glass with a double-silver composite structure containing a copper-aluminum alloy layer and its production process in order to k...
