Problems solved by technology

as known glass / Si 3 N 4 / NiCr / CrN / Si 3 N 4 The solar control film system of the structure uses NiCr and CrNx as the functional layer, but both are not resistant to acid and salt spray corrosion, and the outermost layer of Si 3 N 4 Not resistant to alkali corrosion; also glass / SnO x / SSTN x / SnO x Film structure, but functional layer SSTN x Not resistant to acid corrosion, SnO x The texture is soft and cannot provide sufficient mechanical protection for the functional layer; another known glass / Si 3 N 4 or TiO 2 / Cr / Si 3 N 4 Solar control coated glass with three-layer structure, the functional layer Cr is not resistant to acid corrosion, and the surface layer Si 3 N 4 The film is not resistant to alkali corrosion; and glass / TiO 2 / ZnO x / Cu / NiCr / Si 3 N 4 The coated glass of equal film system also has the same disadvantages
Since the current solar control coated glass has the disadvantages of poor acid and alkali resistance and salt spray corrosion resistance and poor scratch resistance of the surface protection layer, the general coated glass needs to be reprocessed into hollow glass, and the film layer is on the side of the hollow cavity. This can improve the thermal insulation performance of the glass and at the same time protect the film layer

Embodiment 1

[0028] figure 1 It is a schematic diagram of the layer structure of the coated glass according to the embodiment of the present invention. refer to figure 1 The solar control coated glass that can be used in a single piece in this embodiment includes a solar control film layer that is sequentially plated from the glass substrate 1 and on one side of the glass substrate 1. There are 6 layers of film layers in this embodiment. From the glass substrate 1 Outward in sequence are the dielectric barrier layer 2 , the first sacrificial layer 3 , the functional layer 4 , the second sacrificial layer 5 , the dielectric support layer 6 and the top protection layer 7 . In the present embodiment, the glass substrate 1 is common float glass with a thickness of 6mm; the dielectric barrier layer 2 is Si 3 N 4The film layer has a thickness of 42nm; the first sacrificial layer 3 is a NbZr film layer with a thickness of 2nm; the functional layer 4 is a NiCr film layer with a thickness of 6nm...

Embodiment 2

[0041] According to the optical constant of the single-layer film and the principle of thin-film interference, the coated glass with a different reflection color from the glass surface in Example 1 was prepared in this example. The only difference between this embodiment and embodiment 1 is that the dielectric barrier layer 2 is made of Si 3 N 4 film layer with a thickness of 30nm; the first sacrificial layer 3 is a NbZr film layer with a thickness of 2nm; the functional layer 4 is a NiCr film layer with a thickness of 4nm; the second sacrificial layer 5 is a NbZr film layer with a thickness of 2nm; the dielectric support layer 6 is Si 3 N 4 Film layer with a thickness of 28nm; the top protective layer 7 is ZrYO X The film layer has a thickness of 13nm.

[0042] In the embodiment of the present invention, the thickness of the glass substrate 1 can be any thickness, such as the common specifications of existing glass 3mm, 5mm, 6mm, 8mm, 12mm, etc.; the function of the diele...

Abstract

The invention discloses a solar control coated glass capable of being used in one piece and a preparation method of the solar control coated glass. The coated glass comprises a glass substrate and a coating layer arranged at one side surface of the glass substrate, wherein the coating layer sequentially comprises a dielectric barrier layer, a first sacrificial layer, a functional layer, a second sacrificial layer, a dielectric support layer and a top protective layer which are sequentially arranged from the glass substrate to the outer side. The solar control coated glass capable of being used in one piece according to an embodiment of the invention is good in weather resistance and excellent in decorative effect and can be used in one piece.

Description

technical field [0001] The invention relates to the technical field of coated glass, in particular to a solar control coated glass which can be used in a single piece and a preparation method thereof. Background technique [0002] Modern buildings are often equipped with large windows, especially large buildings such as commercial buildings, large shopping malls and office buildings often use glass curtain walls, causing a lot of sunlight to enter the room through the glass curtain walls. The heat lost through the glass curtain wall causes the indoor temperature to continue to rise, increasing the energy consumption of indoor air conditioning and cooling. At this time, it is necessary to use solar control coated glass to reduce the sunlight transmittance through the absorption and reflection of the functional layer and reduce the ingress of sunlight. Indoor solar radiation heat, thereby reducing the energy consumption of the air conditioner and achieving energy-saving effect...
