Problems solved by technology

[0004] For traditional low-E coated glass, NiCr low-priced oxide is usually used as the barrier layer. The transmittance of this type of low-E coated glass is only about 70%, which cannot meet the current market demand for high-quality low-E coated glass.

Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a structural schematic diagram of the single-silver low-emissivity coated glass of the present invention. Such as figure 1 As shown, the single silver low-emissivity coated glass of the present invention sequentially comprises a glass base layer, a bottom protective layer, a first dielectric layer, a barrier layer, a functional layer, a barrier layer, a second dielectric layer, and an outer protective layer. The functional layer is a metallic silver layer with a purity not lower than 99.99%. The barrier layer is located on both sides of the functional layer, and the barrier layer is an AgCu alloy layer.

[0027] The preparation method of the single-silver low-emissivity glass containing silver-copper alloy of the present invention comprises the step of depositing each film layer successively, specifically as follows: ...

Abstract

The invention discloses low-radiation coated glass. The low-radiation coated glass comprises at least one functional layer containing silver or sliver alloy, and is characterized by further comprising an AgCu alloy barrier layer. Compared with the traditional LOW-E glass, the low-radiation coated glass has the advantages that the optical and thermal properties are more excellent, the radiance and the shading coefficient are lower, the U value is low, the color is neutral, the properties are excellent and stable, the silver layer can be guaranteed to be not oxidized and discolored as far as possible during a tempering process, the properties of all film layers are more stable, and the properties of products are guaranteed to be always the same before and after tempering.

Description

technical field [0001] The invention relates to the technical field of low-radiation coated glass, in particular to a low-radiation coated glass containing silver-copper alloy and a preparation method thereof. Background technique [0002] Low-emissivity coated glass is coated with one or more layers of infrared reflective material on the surface of the glass, so that the visible light in the sunlight can pass through, and like an infrared reflector, it excludes the infrared rays in the sunlight and radiates the object twice. It is a special glass that reflects heat back and reduces thermal infrared transmission, thereby reducing the thermal radiation rate of the glass and reducing heat loss. [0003] The low-emissivity film layers in the prior art are all prepared by the magnetron sputtering method. Traditional low-emissivity glass is based on a very thin elemental silver film layer, and it is sandwiched between two anti-reflection metal oxide protective layers (usually Sn...
