[0081] And / or, the material of the high refractive index layer is selected from oxides of at least one element selected from Zn, Sn, Nb, Ti, Cr, Ta and Zr, or includes one or more nitrides and oxynitrides of at least one element selected from Si, Zr and Al.

[0082] And / or, the material of the low refractive index layer is selected from oxides of at least one element selected from Si, Al and B, or fluorides including at least one element selected from Mg, Al and Ba.

[0083] And / or, the total thickness of the high refractive index layer in the antireflection layer is 30nm~110nm, specifically for example, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, or 110nm, etc.

[0084] And / or, the total thickness of the low refractive index layer in the antireflection layer is 40nm~180nm, specifically for example, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm, 150nm, 160nm, 170nm, or 180nm, etc.

[0085] The anti-reflection layer includes two anti-reflection stacks: a first anti-reflection stack 41 and a second anti-reflection stack 42, wherein the second anti-reflection stack 42 is closer to the outer surface than the first anti-reflection stack 41. The thickness ratio of the high refractive index layer in the first anti-stacking layer 41 to the high refractive index layer in the second anti-stacking layer 42 is 0.7 to 1.6. For example, it can be 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, 1.55, or 1.6.

[0086] And / or, the thickness ratio of the low refractive index layer in the first anti-stack layer 41 to the low refractive index layer in the second anti-stack layer 42 is 0.7 to 1, specifically for example, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or 1, etc.

[0087] And / or, the ratio of the total thickness of the low-refractive-index layer in the first anti-reflection stack 41 and the second anti-reflection stack 42 to the total thickness of the high-refractive-index layer in the first anti-reflection stack 41 and the second anti-reflection stack 42 is 1 to 2.3. Specifically, examples include 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, etc.

[0088] Furthermore, the anti-reflective layer is positioned closer to the outer surface than the functional stack, ensuring that the side of the coating structure with high reflectivity faces outwards and the side with low reflectivity faces inwards. This results in the outer surface having a higher reflectivity than the inner surface, making the view of the outside world more natural for passengers.

[0089] like Figure 1 As shown, for example, the coating structure consists of "first glass plate 11 / intermediate adhesive layer 12 / second anti-overlap layer 42 / first anti-overlap layer 41 / first functional layer 21 / first intermediate layer 31 / second functional layer 22 / second intermediate layer 32 / third functional layer 23 / second glass plate 13". The coating structure is located on the third surface.

[0090] like Figure 2 As shown, for example, the coating structure consists of "first glass plate 11 / second anti-overlay layer 42 / first anti-overlay layer 41 / first functional layer 21 / first intermediate layer 31 / second functional layer 22 / second intermediate layer 32 / third functional layer 23 / intermediate adhesive layer 12 / second glass plate 13". The coating structure is located on the second surface.

[0091] In summary, this embodiment, through the design of a combination of reflective and functional layers, not only enables the coated glass 1 to have low in-vehicle reflectivity and neutral transparent color, making the outside scene observed by passengers more natural, but also enables the coated glass 1 to have low total solar transmittance, reflecting more heat, reducing the radiation of sunlight inside the vehicle, and reflecting the heat from outside the vehicle, thus avoiding overheating inside the vehicle in summer.

[0092] In one implementation, such as Figures 1-2 As shown, the coating structure further includes a dielectric layer, which is disposed between the antireflective layer and the functional layer, and / or between the functional layer and the intermediate layer.

[0093] The dielectric layer is used to protect the functional layer from oxidation.

[0094] like Figure 1As shown, for example, the coating structure consists of "first glass plate 11 / intermediate adhesive layer 12 / second anti-overlap layer 42 / first anti-overlap layer 41 / first dielectric layer 81 / first functional layer 21 / second dielectric layer 82 / first intermediate layer 31 / third dielectric layer 83 / second functional layer 22 / fourth dielectric layer 84 / second intermediate layer 32 / fifth dielectric layer 85 / third functional layer 23 / sixth dielectric layer 86 / second glass plate 13". The coating structure is located on the third surface.

[0095] like Figure 2 As shown, for example, the coating structure consists of "first glass plate 11 / second anti-overlay layer 42 / first anti-overlay layer 41 / first dielectric layer 81 / first functional layer 21 / second dielectric layer 82 / first intermediate layer 31 / third dielectric layer 83 / second functional layer 22 / fourth dielectric layer 84 / second intermediate layer 32 / fifth dielectric layer 85 / third functional layer 23 / sixth dielectric layer 86 / intermediate adhesive layer 12 / second glass plate 13". The coating structure is located on the second surface.

[0096] Furthermore, the material of the dielectric layer is selected from at least one of AZO, Ti alloy, NbOx, TiOx, NiCr, NiCrOx, ZnAlOx, ZnOx, and SnOx, wherein x in SnOx satisfies: 1 < x ≤ 3.

[0097] And / or, the thickness of the dielectric layer is 0.5nm to 20nm, specifically for example, 0.5nm, or 1nm, or 2nm, or 3nm, or 4nm, or 5nm, or 6nm, or 7nm, or 8nm, or 9nm, or 10nm, or 11nm, or 12nm, or 13nm, or 14nm, or 15nm, or 16nm, or 17nm, or 18nm, or 19nm, or 20nm, etc.

[0098] In another embodiment, such as Figure 2 As shown, the coating structure further includes a protective layer 60, which is the film layer furthest from the glass substrate in the coating structure.

[0099] The protective layer 60 is used to improve the overall film's resistance to environmental and mechanical properties. For example, the protective layer 60 is disposed on the side of the functional stack away from the antireflective layer, and the protective layer 60 is the film layer in the coating structure that is furthest from the glass substrate in contact with the antireflective layer.

[0100] like Figure 2As shown, for example, the coating structure consists of "first glass plate 11 / second anti-overlay layer 42 / first anti-overlay layer 41 / first dielectric layer 81 / first functional layer 21 / second dielectric layer 82 / first intermediate layer 31 / third dielectric layer 83 / second functional layer 22 / fourth dielectric layer 84 / second intermediate layer 32 / fifth dielectric layer 85 / third functional layer 23 / sixth dielectric layer 86 / protective layer 60 / intermediate adhesive layer 12 / second glass plate 13". The coating structure is located on the second surface.

[0101] Furthermore, the material of the protective layer 60 is selected from oxides, nitrides or oxynitrides of at least one element selected from Si, Zn, Mg, Sn, Ti, Nb, Zr, In and Al.

[0102] And / or, the thickness of the protective layer 60 is 30nm~70nm, specifically for example, 30nm, 35nm, 40nm, 45nm, 50nm, 55nm, 60nm, 65nm, or 70nm, etc.

[0103] And / or, the coating structure further includes a dielectric layer disposed between the functional layer and the protective layer.

[0104] In yet another implementation, such as Figure 1 As shown, the coating structure further includes an adhesion layer 50, which is disposed on the side of the functional stack away from the antireflective layer and contacts the surface of the glass substrate.

[0105] The adhesion layer 50 is used to increase the adhesion between the film layer and the glass substrate.

[0106] like Figure 1 As shown, for example, the coating structure consists of "first glass plate 11 / intermediate adhesive layer 12 / second anti-overlap layer 42 / first anti-overlap layer 41 / first dielectric layer 81 / first functional layer 21 / second dielectric layer 82 / first intermediate layer 31 / third dielectric layer 83 / second functional layer 22 / fourth dielectric layer 84 / second intermediate layer 32 / fifth dielectric layer 85 / third functional layer 23 / sixth dielectric layer 86 / adhesion layer 50 / second glass plate 13". The coating structure is located on the third surface.

[0107] Furthermore, the material of the adhesion layer 50 is selected from oxides, nitrides or oxynitrides of at least one element selected from Si, Zn, Mg, Sn, Ti, Nb, Zr, In and Al.

[0108] And / or, the thickness of the adhesion layer 50 is 30nm~70nm, specifically for example, 30nm, 35nm, 40nm, 45nm, 50nm, 55nm, 60nm, 65nm, or 70nm, etc.

[0109] And / or, the coating structure further includes a dielectric layer disposed between the functional layer and the adhesion layer.

[0110] In another embodiment, the coated glass 1 further includes an infrared reflective layer 70, which is disposed on the surface of the second glass plate 13 facing the intermediate adhesive layer 12 or on the surface of the second glass plate 13 away from the intermediate adhesive layer 12.

[0111] The infrared reflective layer 70 can be disposed on the third or fourth surface. Optionally, the infrared reflective layer 70 is selected from a double silver film system, a triple silver film system, or an ITO film system.

[0112] An example of a double silver film structure is as follows: ZnSnO3 / AZO / Ag / AZO / ZnSnO3 / AZO / Ag / AZO / ZnSnO3 / SiNx.

[0113] An example of a three-silver film structure is as follows: ZnSnO3 / AZO / Ag / AZO / ZnSnO3 / AZO / Ag / AZO / ZnSnO3 / AZO / Ag / AZO / ZnSnO3 / SiNx.

[0114] An example of an ITO film structure is as follows: SiNx / SiO2 / ITO / SiNx / ITO / SiNx / ITO / SiO2.

[0115] like Figure 2 As shown, for example, the coating structure consists of "first glass plate 11 / second anti-overlay layer 42 / first anti-overlay layer 41 / first dielectric layer 81 / first functional layer 21 / second dielectric layer 82 / first intermediate layer 31 / third dielectric layer 83 / second functional layer 22 / fourth dielectric layer 84 / second intermediate layer 32 / fifth dielectric layer 85 / third functional layer 23 / sixth dielectric layer 86 / protective layer 60 / intermediate adhesive layer 12 / infrared reflective layer 70 / second glass plate 13". The infrared reflective layer 70 is located on the third surface, and the coating structure is located on the second surface.

[0116] Further, the emissivity E of the infrared reflective layer 70 is ≤0.15, specifically, examples include 0.15, 0.14, 0.13, 0.12, 0.11, 0.10, 0.09, 0.08, 0.07, 0.06, 0.05, 0.04, 0.03, 0.02, or 0.01, etc. Preferably, the emissivity E of the infrared reflective layer 70 is ≤0.10. More preferably, the emissivity E of the infrared reflective layer 70 is ≤0.05.

[0117] Therefore, by adding an infrared reflective layer 70, this embodiment can further reduce the total solar transmittance of the coated glass 1, further reflect more heat, further reduce the radiation of sunlight inside the vehicle, and reflect the heat outside the vehicle to avoid overheating inside the vehicle in summer.

[0118] In yet another embodiment, the first glass plate 11 is anti-glare glass.

[0119] Anti-glare glass, also known as AG glass, refers to glass whose surface is specially treated by physical or chemical means such as etching, corrosion, nano-imprinting, coating, sandblasting, or polishing to form a diffuse reflection structure. In this embodiment, by using anti-glare glass for the first glass plate 11, when light shines on the outer surface of the coated glass 1, it is no longer specular reflection, but diffuse reflection. On the one hand, it scatters the sunlight entering the vehicle, reducing the transmittance of sunlight; on the other hand, it reduces glare from concentrated reflections, avoids light pollution from the roof, further improves the user's visual comfort, further improves the vehicle's aesthetics, and further improves the user's experience.

[0120] Sunlight received by glass can generally be divided into the following components: Reflection (R) + Transmission (T) + Absorption (D) = 100%. Sunroof glass with related technologies often achieves approximately 20% Reflection (R), 15% Transmission (T), and 65% Absorption (D) by using a gray PVB interlayer or a heat-absorbing NiCr film. However, due to the excessively high absorption (D), secondary radiation occurs, radiating heat into the vehicle's interior. Furthermore, the excessive absorption (D) causes the sunroof glass to become extremely hot to the touch in summer.

[0121] However, by using the coated glass 1 provided in this application, the coated glass 1 reflects most of the heat away by setting functional layers. For example, the reflection R of the double functional layer is ≥65%, and the reflection R of the triple functional layer is ≥75%, which avoids the sunroof glass from radiating heat into the car and greatly alleviates the problem of the sunroof glass getting too hot in summer.

[0122] Meanwhile, this application also makes the first glass plate 11 an anti-glare glass, which serves as the outer glass plate, converting specular reflection into diffuse reflection, thus avoiding the problem of light pollution.

[0123] This application provides a vehicle, the vehicle including a body and coated glass as described above, the coated glass being disposed on the body.

[0124] The vehicle provided in this application uses the coated glass described above. The coated glass, through the design of anti-reflective layers and functional layers, not only has low interior reflectivity and neutral color perception, making the view of the outside scene more natural for passengers, but also has low total solar transmittance, which can reflect more heat, reduce the radiation of sunlight inside the vehicle, and reflect the heat from outside the vehicle, thus preventing the vehicle interior from overheating in summer.

[0125] To make the objectives and advantages of this application clearer, the effects of the coated glass of this application will be further explained in detail below with reference to specific embodiments.

[0126] In Comparative Example 1 and Examples 1-8, examples are illustrated by applying a coating structure to a glass substrate. The specific film materials and thicknesses of the coating structure and the glass substrate are shown in Tables 1-4. Furthermore, the following parameters of the coated glass in Comparative Example 1 and Examples 1-8 were measured respectively: (1) The reflectivity of the outer surface of the coated glass, in %; (2) Lab2 values ​​of the outer surface reflection of coated glass: a2 value and b2 value; (3) The reflectivity of the inner surface of the coated glass, in %; (4) Lab3 value of inner surface reflection of coated glass: a3 value and b3 value; (5) Visible light transmittance of coated glass, in %; (6) Transmittance Lab1 value of coated glass: a1 value and b1 value; The specific index data of Comparative Example 1 and Examples 1-8 are shown in Tables 1 to 4.

[0127] Table 1. Coating materials, thicknesses, and performance parameters of the coated glass in Comparative Example 1 and Examples 1-2.

[0128] Table 2. Coating materials, thicknesses, and performance parameters of the coated glass in Examples 3-4

[0129] Table 3. Coating materials, thicknesses, and performance parameters of the coated glass in Examples 5-6

[0130] Table 4. Coating materials, thicknesses, and performance parameters of the coated glass in Examples 7-8

[0131] Comparative Example 1 uses a conventional anti-reflection structure. Although the reflectivity of the outer surface is greatly improved, the reflectivity of the inner surface is as high as 21.2%, the reflection a3 value is -1.1, the reflection b3 value is -2.1, and the transmittance Lab1 value is a1 value of 7.6 and b1 value of 2.6. The field of view observed through the coated glass is "filtered" with an orange color, making it unsuitable for use in automotive sunroof products.

[0132] Example 1 uses a conventional dual-functional layer structure + anti-reflection layer, which not only greatly improves the reflectivity of the outer surface, but also the reflectivity of the inner surface is only 4.9%. Furthermore, the Lab1 value has a value of a1=0.4 and a value of b1=-2.8, and the field of view observed through the coated glass is a natural neutral color, which is suitable for use in automotive sunroof products.

[0133] Example 2 uses a conventional dual-functional layer structure + a double-layer anti-reflective layer, which not only greatly improves the reflectivity of the outer surface, but also the reflectivity of the inner surface is only 4.7%. Furthermore, the Lab1 value has a value of a1=0.5 and a value of b1=-4.0, and the field of view observed through the coated glass is a natural neutral color, which is suitable for use in automotive sunroof products.

[0134] Example 3 uses a conventional three-functional layer structure plus an anti-reflective layer, which not only greatly improves the reflectivity of the outer surface, but also reduces the reflectivity of the inner surface to only 4.5%. Furthermore, the Lab1 values ​​show a1=0.4 and b1=-9.4, and the field of view observed through the coated glass is light blue, making it suitable for automotive sunroof products.

[0135] Example 4 uses a conventional three-functional layer structure + double anti-reflective layer, which not only greatly improves the reflectivity of the outer surface, but also the reflectivity of the inner surface is only 4.8%. Furthermore, the Lab1 value has a value of a1=0.6 and a value of b1=-11.7, and the field of view observed through the coated glass is light blue, making it suitable for automotive sunroof products.

[0136] Example 5 uses a conventional dual-functional layer structure plus an anti-reflective layer. Compared with Example 1, the film structure is inverted. Not only is the reflectivity of the outer surface greatly improved, but the reflectivity of the inner surface is also 5.0%. Furthermore, the transmittance Lab1 values ​​are a1=-2.6 and b1=-9.9, and the field of view observed through the coated glass is light blue, making it suitable for automotive sunroof products.

[0137] Among them, the inverted film structure means that the reflective layer is closer to the outer surface than the functional stack, so that the side of the coating structure with high reflectivity faces outward and the side with low reflectivity faces inward. This makes the reflectivity of the outer surface greater than that of the inner surface, making the scene outside the vehicle more natural for passengers.

[0138] Example 6 uses a conventional dual-functional layer structure plus a dual-layer anti-reflective layer. Compared with Example 2, the film structure is inverted. Not only is the reflectivity of the outer surface greatly improved, but the reflectivity of the inner surface is also 4.7%. Furthermore, the transmittance Lab1 values ​​are a1=-0.3 and b1=-11.3, and the field of view observed through the coated glass is light blue, making it suitable for automotive sunroof products.

[0139] Example 7 uses a conventional three-functional layer structure plus an anti-reflective layer. Compared with Example 3, the film structure is inverted. Not only is the reflectivity of the outer surface greatly improved, but the reflectivity of the inner surface is only 3.7%. Furthermore, the transmittance Lab1 values ​​are a1=-1.3 and b1=-6.4, resulting in a neutral color field of view when viewed through the coated glass, making it suitable for automotive sunroof products.

[0140] Example 8 uses a conventional three-functional layer structure plus a double-layer anti-reflective layer. Compared with Example 4, the film structure is inverted. Not only is the reflectivity of the outer surface greatly improved, but the reflectivity of the inner surface is only 4.5%. Furthermore, the transmittance Lab1 values ​​are a1=-2.8 and b1=-9.5, and the field of view observed through the coated glass is light blue, making it suitable for automotive sunroof products.

[0141] In Comparative Examples 2-5 and Examples 9-16, examples are illustrated by applying a coating structure to laminated glass. The specific film materials and thicknesses of the coating structure and the glass substrate are shown in Tables 5-8. Furthermore, the following parameters of the coated glass in Comparative Examples 2-5 and Examples 9-16 were measured respectively: (1) The reflectivity of the outer surface of the coated glass, in %; (2) The reflectivity of the inner surface of the coated glass, in %; (3) Total solar transmittance Tts of coated glass, in %; The specific index data of Comparative Examples 2-5 and Examples 9-16 are shown in Tables 5-8.

[0145] Table 8. Coating materials, thicknesses, and performance parameters of the coated glass in Examples 14-16

[0146] In the above embodiments, the three-silver film system structure is formed by depositing the following film layers on a 2.1 mm white glass substrate: ZnSnO3(43.5nm) / AZO(10nm) / Ag(10.7nm) / AZO(10nm) / ZnSnO3(53nm) / AZO(10nm) / Ag(14.2nm) / AZO(10 nm) / ZnSnO3(60.2nm) / AZO(10nm) / Ag(16.4nm) / AZO(10nm) / ZnSnO3(15nm) / SiNx(22.5nm), its resistance value is 1.32Ω.

[0147] In the above embodiments, the ITO film system structure is formed by depositing the following film layer on a 2.1 mm gray glass substrate: The structure is SiNx (24.2nm) / SiO2 (33.2nm) / ITO (30nm) / SiNx (32.6nm) / ITO (143.1nm) / SiNx (60nm) / ITO (200nm) / SiO2 (74.4nm), with a resistance of 7.4Ω.

[0148] Comparative Example 2 shows a standard three-silver film sunroof combination, with a Tts of 36%, indicating significant heat transmission and poor heat insulation in summer. Comparative Example 3 uses gray PVB to block heat, with a Tts of 27.4%, still relatively high and unfavorable for summer heat insulation. Furthermore, the gray PVB absorbs most of the heat, causing secondary radiation into the car and resulting in the sunroof glass becoming "hot to the touch." Comparative Example 4 uses a double-gray glass ITO heat insulation film system, with a Tts of 28.1%, still relatively high and unfavorable for summer heat insulation. Additionally, the gray glass absorbs most of the heat, causing secondary radiation into the car and resulting in the sunroof glass becoming "hot to the touch."

[0149] Comparative Example 5 uses a common triple silver film system for the first glass plate, while the second glass plate uses the film system of Example 1. The intermediate adhesive layer uses common PVB, and it can be seen that its Tts is 18.8%, which is not conducive to heat insulation in summer.

[0150] Example 9 uses 2.1mm clear glass as the first glass plate and the film system of Example 1 as the second glass plate. The intermediate adhesive layer is ordinary PVB. It can be seen that its Tts is 8.7%, which is greatly reduced.

[0151] Example 10 uses 2.1mm AG glass as the first glass plate and the film system of Example 2 as the second glass plate. The intermediate adhesive layer is ordinary PVB. It can be seen that its Tts is 6.6%, which is greatly reduced.

[0152] Example 11 uses ordinary clear glass as the first glass plate and the film system of Example 3 as the second glass plate. The intermediate adhesive layer is ordinary PVB. It can be seen that its Tts is 8.6%, which is greatly reduced.

[0153] Example 12 uses 2.1mm AG glass as the first glass plate and the film system of Example 4 as the second glass plate. The intermediate adhesive layer is ordinary PVB, and the fourth surface is coated with an ITO film system. It can be seen that its Tts is 5.4%, which is greatly reduced.

[0154] Example 13 uses the film system of Example 5 for the first glass plate and 2.1mm clear glass for the second glass plate. The intermediate adhesive layer is ordinary PVB. It can be seen that its Tts is 8.5%, which is greatly reduced.

[0155] Example 14 uses the film system of Example 6 for the first glass plate and 2.1mm clear glass for the second glass plate. The intermediate adhesive layer is ordinary PVB. It can be seen that its Tts is 7.5%, which is greatly reduced.

[0156] Example 15 involves depositing the film system of Example 7 on a 2.1mm AG glass first glass plate. The second glass plate uses ordinary white glass, and the intermediate adhesive layer uses gray PVB. It can be seen that its Tts is 7.2%, which is greatly reduced.

[0157] Example 16 involves depositing the film system of Example 8 on a 2.1mm AG glass first glass plate, using triple silver glass as the second glass plate, depositing an ITO film system on the fourth surface, and using ordinary PVB as the intermediate bonding layer. It can be seen that its Tts is 5.5%, which is greatly reduced.

[0158] In summary, this application, through the design of a combination of anti-reflective layer and functional stacked layer, along with an infrared reflective layer, not only enables the coated glass to have low interior reflectivity and neutral color perception, making the outside scene observed by passengers more natural, but also enables the coated glass to have low total solar transmittance, reflecting more heat, reducing the radiation of sunlight inside the vehicle, and reflecting the heat from outside the vehicle, thus preventing the vehicle interior from overheating in summer.
