Description

Technical Field

[0001] The invention relates to the technical field of glass, in particular to bird-friendly glass. Background Art

[0002] Due to the transparent and reflective properties of glass, birds often cannot recognize the existence of glass, and thus accidentally hit the glass, resulting in injury or even death. In order to reduce the occurrence of this situation, the prior art mainly uses some reflective materials to form patterns on the glass surface to warn birds. However, the processing method of using some reflective materials to form patterns for warning has the following defects, that is, reflective materials often have low transparency and are visible to the human eye, thus not only reducing the transmittance of the glass, but also directly affecting the aesthetics of the building. In order to solve this problem, the present invention aims to provide a glass with high light transmittance and high ultraviolet reflectance, which can effectively protect birds without affecting the transmittance. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides a bird-friendly glass.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a bird-friendly glass, including a glass substrate, a high-transmittance protective film layer is arranged on the upper end face of the glass substrate, the high-transmittance protective film layer includes a bidirectional composite structure film and a titanium oxide layer, the bidirectional composite structure film includes a first stable protective layer and a second stable protective layer, the titanium oxide layer is composited between the first stable protective layer and the second stable protective layer, the first stable protective layer is plated on the outdoor surface of the glass substrate, and the second stable protective layer is plated on the outdoor surface of the titanium oxide layer. The hierarchical structure of the bird-friendly glass is, from bottom to top, the glass substrate, the first stable protective layer, the titanium oxide layer and the second stable protective layer.

[0005] Among them, the first stable protective layer and the second stable protective layer are used to reduce the reflectivity of the titanium oxide layer in the visible light band, the first stable protective layer and the second stable protective layer both contain silicon nitride and aluminum-doped silicon nitride, the first stable protective layer has a layer thickness of 0nm to 200nm, and the second stable protective layer has a layer thickness of 40nm to 200nm.

[0006] Preferably, the layer thickness of the glass substrate is 0.4 mm to 20 mm.

[0007] Preferably, the titanium oxide layer has a layer thickness of 10 nm to 100 nm.

[0008] Preferably, the first stable protective layer, the titanium oxide layer and the second stable protective layer are formed by magnetron sputtering from bottom to top in sequence.

[0009] Compared with the prior art, the beneficial effects of the present invention are: by setting a titanium oxide layer to reflect or scatter ultraviolet rays, the ultraviolet reflection effect of the glass substrate is increased; the first stable protective layer is set on the outer layer of the titanium oxide layer, which can reduce the reflectivity of the titanium oxide layer in the visible light band and increase the visible light transmittance of the glass substrate; the second stable protective layer is set on a layer of the titanium oxide layer close to the glass substrate, which can reduce the reflectivity of titanium oxide in the visible light band and increase the visible light transmittance of the glass; and after the first stable protective layer and the second stable protective layer cover both sides of the titanium oxide layer, their high wear resistance can effectively protect titanium oxide, so that the glass can have both high ultraviolet reflectivity and high visible light transmittance, thereby achieving the purpose of protecting birds.

[0020] In an optional implementation manner of this embodiment, in an optional implementation manner of this embodiment, the layer thickness of the titanium oxide layer 3 is 10nm to 100nm.

[0021] In this embodiment, the titanium oxide layer 3 can reflect or scatter ultraviolet rays for the glass substrate 1 after being deposited into a layer because titanium oxide has the characteristics of stable chemical properties, high refractive index and transparency in the visible light band.

[0022] The first stable protective layer 21, the titanium oxide layer 3 and the second stable protective layer 22 are deposited in sequence from bottom to top by magnetron sputtering.

At the same time, after the first stable protective layer 21 and the second stable protective layer 22 cover the upper and lower sides of the titanium oxide layer 3, their excellent high wear resistance can effectively protect the titanium oxide layer 3.

[0024] Example 2

[0025] like Figure 1 , Figure 2 as well as Figure 3 As shown, a bird-friendly glass described in the present invention includes a glass substrate 1, a high-transmittance protective film layer is arranged on the upper end surface of the glass substrate 1, the high-transmittance protective film layer includes a bidirectional composite structure film 2 and a titanium oxide layer 3, the bidirectional composite structure film 2 includes a first stable protective layer 21 and a second stable protective layer 22, the titanium oxide layer 3 is composited between the first stable protective layer 21 and the second stable protective layer 22, the first stable protective layer 21 is plated on the outdoor surface of the glass substrate 1, and the second stable protective layer 22 is plated on the outdoor surface of the titanium oxide layer 3, and the hierarchical structure of the bird-friendly glass is, from bottom to top, glass substrate 1, first stable protective layer 21, titanium oxide layer 3 and second stable protective layer 22.

The layer thickness of the first stable protective layer 21 is 11nm, and the layer thickness of the second stable protective layer 22 is 83nm.

[0028] In this embodiment, the first stable protective layer 21 and the second stable protective layer 22 are both made of aluminum-doped silicon nitride, and the aluminum content in the aluminum-doped silicon nitride is 10%.

[0029] In an optional implementation of this embodiment, the layer thickness of the glass substrate 1 is 0.4 mm to 20 mm.

[0030] In an optional implementation of this embodiment, the layer thickness of the titanium oxide layer 3 is 20 nm.

[0031] In this embodiment, in conjunction with the storytelling drawings Figure 2 As shown, quartz glass with a glass thickness of 4 mm was selected as the control group 1, and the spectrum data of the control group 1 and the embodiment 2 were measured by ultraviolet visible infrared spectrophotometer. The test results are shown in the following technical table (ultraviolet light band: 300nm ~ 400nm, visible light band: 400nm ~ 780nm), and the spectrum comparison of transmittance is as follows: Figure 2 As shown, the glass surface reflectance spectrum is compared Figure 3 shown.

[0032] Example 3

[0033] like Figure 1 , Figure 2 as well as Figure 3 As shown, a bird-friendly glass described in the present invention includes a glass substrate 1, a high-transmittance protective film layer is arranged on the upper end surface of the glass substrate 1, the high-transmittance protective film layer includes a bidirectional composite structure film 2 and a titanium oxide layer 3, the bidirectional composite structure film 2 includes a first stable protective layer 21 and a second stable protective layer 22, the titanium oxide layer 3 is composited between the first stable protective layer 21 and the second stable protective layer 22, the first stable protective layer 21 is plated on the outdoor surface of the glass substrate 1, and the second stable protective layer 22 is plated on the outdoor surface of the titanium oxide layer 3, and the hierarchical structure of the bird-friendly glass is, from bottom to top, glass substrate 1, first stable protective layer 21, titanium oxide layer 3 and second stable protective layer 22.

[0034] In this embodiment, the glass substrate 1 is made of quartz glass and has a thickness of 4 mm.

[0035] Among them, the first stable protective layer 21 and the second stable protective layer 22 are used to reduce the reflectivity of the titanium oxide layer 3 in the visible light band.

[0039] Combined with Example 2 and Example 3, samples were constructed for testing, and quartz glass with a thickness of 4 mm was selected as the control group 1, and quartz glass with a thickness of 4 mm and plated with titanium oxide with a thickness of 20 nm was selected as the control group 2. The spectral data of the control group 1, the control group 2, Example 1 and Example 2 were measured using an ultraviolet-visible-infrared spectrophotometer. The final test results are shown in the following table (the test band is the ultraviolet band: 300nm-400nm, the visible light band: 400nm-780nm), and the spectral comparison of the transmittance is shown in the accompanying figure of the specification. Figure 2 As shown, the glass surface reflectivity spectrum is compared with the attached figure of the specification Figure 3 shown.

[0040]

[0041] It can be seen from the above chart data that the ultraviolet reflectivity of the glass surface of the control group 2 is increased by about 35% compared with the control group 1, indicating that the titanium oxide layer can improve the ultraviolet reflectivity of the glass, but the visible light transmittance is reduced by about 30%. The ultraviolet reflectivity of the glass surface of Example 2 and Example 3 is not much different from that of the control group 2, and the visible light transmittance is increased by about 30%, but the visible light transmittance of the glass is almost not affected compared with the control group 1.
