Description

Technical Field

[0001] The present invention relates to the field of glass, and in particular to a laminated heat-insulating glass with local high infrared transmittance and a vehicle comprising the laminated heat-insulating glass. Background Art

[0002] Automobile windshields are typically laminated glass, comprising an outer glass panel, a thermoplastic interlayer, and an inner glass panel. When a multi-function camera or lidar is mounted on the inner surface of the inner glass panel, the transmission and / or reception of the multi-function camera or lidar's signal data must pass through the outer glass panel, the thermoplastic interlayer, and the inner glass panel. Because both the glass itself and the thermoplastic interlayer (e.g., PVB) absorb infrared rays, conventional laminated glass can block the transmission of signals from 905nm lidars, 1550nm lidars, and 850-1400nm infrared cameras, thereby affecting their normal operation and resulting in unsatisfactory adaptation. Furthermore, to enhance driving safety and comfort, an increasing number of automotive glass panels are now equipped with electric heating or thermal insulation features. These features can be achieved by depositing metal films or transparent conductive oxide films on the surface of the glass. However, because metal films or transparent conductive oxide films reflect infrared rays, automotive glass with electric heating or thermal insulation features presents a greater barrier to the transmission of signals from lidars and infrared cameras.

[0003] CN101678651A discloses a laminated vehicle window glass suitable for use with optical sensors (e.g., LIDAR sensors). The laminated vehicle window glass comprises first and second glazing layers connected by an interlayer material layer therebetween. The first glazing layer is a body-tinted glass sheet. The window glass has a transmittance of at least 30% within the wavelength range of 400 to 2100 nm and at least 32% within the wavelength range of 750 to 1300 nm. However, such transmittances are still insufficient for practical use with LIDAR or infrared cameras. CN101037099A discloses an apparatus and method for installing an outward-facing infrared camera in a vehicle. The apparatus employs a plastic insert with an infrared-seeing portion installed in a through-hole in the windshield. This technical solution compromises the integrity of the outer surface of the front windshield, reducing safety to a certain extent. Furthermore, laminated glass with through-holes suffers from manufacturing issues such as large overlap and difficulty in vacuuming during assembly. Summary of the Invention

[0034] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0035] The laminated insulating glass provided by the present invention forms an infrared anti-reflection layer and a thermal insulation layer by coating the entire surface of the glass substrate. The thermal insulation layer is then partially de-coated to create a de-coating area suitable for mounting highly sensitive communication sensors such as lidar and infrared cameras. This provides advantages such as a simple process and consistent overall appearance. Furthermore, the high-refractive-index layer / low-refractive-index layer stacked structure of the infrared anti-reflection layer is thicker than the low-refractive-index layer, ensuring accuracy and efficiency in wide-angle sensor detection.

[0036] like Figures 1-4 As shown, the laminated insulating glass of the present invention comprises an outer glass plate 1, an inner glass plate 2 and a thermoplastic interlayer 3; the outer glass plate 1 has a first surface 11 and a second surface 12, the inner glass plate 2 has a third surface 21 and a fourth surface 22; the thermoplastic interlayer 3 is sandwiched between the second surface 12 and the third surface 21;

[0037] The laminated insulating glass further includes an infrared anti-reflection layer 5 and a thermal insulation layer 4, and the infrared anti-reflection layer 5 and the thermal insulation layer 4 are not located on the same glass surface; the orthographic projection of the infrared anti-reflection layer 5 on the first surface 12 and the orthographic projection of the thermal insulation layer 4 on the first surface 12 have an overlapping area, and the thermal insulation layer 4 is provided with a film removal area 41, and the orthographic projection of the infrared anti-reflection layer 5 on the thermal insulation layer 4 covers the film removal area 41. Specifically, the infrared anti-reflection layer 5 can be provided on the second surface 12, the third surface 21, or the fourth surface 22. Specifically, the thermal insulation layer 4 can be provided on the second surface 12, the third surface 21, or between the second surface 12 and the third surface 21.

[0038] like Figure 1 As shown, in a specific embodiment, the laminated insulating glass includes an outer glass panel 1, an inner glass panel 2 and a thermoplastic interlayer 3; the outer glass panel 1 has a first surface 11 and a second surface 12, and the inner glass panel 2 has a third surface 21 and a fourth surface 22; the thermoplastic interlayer 3 is sandwiched between the second surface 12 and the third surface 21.

[0039] An infrared anti-reflection layer 5 is provided on the fourth surface 22 , a heat insulation layer 4 is provided on the second surface 12 , and a film removal area 41 is provided in the heat insulation layer 4 .

[0040] like Figure 3 As shown, this specific embodiment is Figure 1 The difference is that the infrared anti-reflection layer 5 is arranged on the third surface 21 , and the heat insulation layer 4 is arranged on the second surface 12 .

[0041] like Figure 4 As shown, this specific embodiment is Figure 1 The difference is that the infrared anti-reflection layer 5 is arranged on the second surface 12 , and the heat insulation layer 4 is arranged on the third surface 21 .

[0042] Figure 1 、 Figure 3 and Figure 4 In the laminated insulating glass, the infrared anti-reflection layer 5 and the thermal insulation layer 4 are respectively provided on different glass surfaces, and are formed by coating the entire surface of the different glass surfaces, and then partially removing the film in the thermal insulation layer 4 to form the film removal area 41. In addition, the thermal insulation layer 4 can also be provided between the second surface 12 and the third surface 21. Specifically, the thermal insulation layer 4 can be formed by coating the surface of an organic resin film, and the film removal area 41 can be formed by partially shielding it during the coating process, or the film removal area 41 can be formed by partially removing the film after the entire surface is coated. Thereafter, the organic resin film provided with the thermal insulation layer 4 is laminated between the second surface 12 and the third surface 21. Specifically, it can be located between the second surface 12 and the thermoplastic interlayer 3, or between the thermoplastic interlayer 3 and the third surface 21, or within the thermoplastic interlayer 3. For example, the thermoplastic interlayer 3 includes two sheets of transparent PVB, and the organic resin film provided with the thermal insulation layer 4 is sandwiched between the two sheets of transparent PVB. Examples of the organic resin film include polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene naphthalate (PEN), and cellulose acetate (CA).

[0043] like Figure 2 As shown, in the laminated insulating glass 100, the film removal area 41 of the insulation layer 4 at least covers the area 102, that is, the area 102 is the area of ​​the laminated insulating glass 100 that is only covered by the infrared anti-reflection layer 5. The detection signals of highly sensitive communication sensors such as lidar and infrared cameras pass through the area 102. The infrared anti-reflection layer 5 can improve the transmittance of the detection signal passing through the area 102. Since there is no insulation layer 4 in the film removal area 41, the transmittance of the detection signal passing through the area 102 is not interfered by the insulation layer 4, thereby achieving normal operation of the sensor with higher accuracy and efficiency.

[0044] like Figure 2As shown, in the laminated insulating glass 100, the overlapping area of ​​the laminated insulating glass 100 covers area 101. Specifically, area 101 is the area of ​​the laminated insulating glass 100 covered with both the thermal insulation layer 4 and the infrared anti-reflection layer 5. The driver and passengers in the vehicle observe the exterior environment through area 101. The thermal insulation layer 4 significantly reduces the total solar transmittance to below 50%, improving thermal comfort inside the vehicle. Simultaneously, the infrared anti-reflection layer 5 further reduces the visible light reflectance of area 101 on the fourth side and improves the reflected color of area 101 on the first side, allowing the laminated insulating glass 100 to use a thermal insulation layer 4 with even higher performance.

[0045] In the laminated insulating glass 100 of the present invention, the infrared transmittance-enhancing layer 5 and the thermal insulation layer 4 are not on the same glass surface. They can be coated on different glass surfaces or organic resin films respectively, and the overall appearance is consistent. Only local film removal is required in the thermal insulation layer. The removed film area corresponds to the signal transmission area of ​​the laser radar or infrared camera. The infrared transmittance-enhancing layer does not need to be removed. The process is simple and the difficulty is low.

[0046] Preferably, the orthographic projection of the infrared anti-reflection layer 5 on the first surface occupies more than 70% of the area of ​​the first surface, and the orthographic projection of the heat insulation layer 4 on the first surface occupies more than 70% of the area of ​​the first surface; the overlapping area occupies at least more than 80% of the orthographic projection of the heat insulation layer 4 on the first surface. Figure 2 As shown, the film removal area 41 in the heat insulation layer 4 occupies less than 20% of the area, and the laminated insulating glass is only covered with the infrared anti-reflection layer 5 in the film removal area 41 of the heat insulation layer.

[0047] The infrared transmittance-enhancing layer 5 comprises, in order, a first high-refractive-index layer, a first low-refractive-index layer, a second high-refractive-index layer, and a second low-refractive-index layer, located away from the glass surface. The physical thickness of the first high-refractive-index layer is greater than that of the first low-refractive-index layer, and the physical thickness of the second high-refractive-index layer is greater than that of the second low-refractive-index layer. By designing a four-layer structure for the infrared transmittance-enhancing layer 5, the present invention not only improves the transmittance of the detection signal through region 102, but also further reduces the visible light reflectance of the fourth surface of region 101 and improves the reflection color of the first surface of region 101, thereby achieving better coordination with the thermal insulation layer 4.

[0048] The refractive index of the first high refractive index layer is 1.8 to 2.7, and the physical thickness of the first high refractive index layer is 110 nm to 160 nm, such as 110 nm, 120 nm, 130 nm, 140 nm, 150 nm, 160 nm, etc., more preferably 120 nm to 150 nm. Preferably, the refractive index of the first low refractive index layer is 1.3 to 1.7, and the physical thickness of the first low refractive index layer is 5 nm to 50 nm, such as 5 nm, 10 nm, 15 nm, 20 nm, 25 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, etc., more preferably 15 nm to 35 nm. Preferably, the refractive index of the second high refractive index layer is 1.8-2.7, and the physical thickness of the second high refractive index layer is 100nm-160nm, such as 100nm, 110nm, 120nm, 130nm, 140nm, 150nm, 160nm, etc., more preferably 100nm-140nm; preferably, the refractive index of the second low refractive index layer is 1.3-1.7, and the physical thickness of the second low refractive index layer is 55nm-110nm, such as 55nm, 60nm, 65nm, 70nm, 75nm, 80nm, 85nm, 90nm, 95nm, 100nm, 110nm, etc., more preferably 60nm-90nm. The refractive index is the refractive index at a wavelength of 550nm.

[0049] Wherein, the difference between the physical thickness of the first high refractive index layer and the physical thickness of the first low refractive index layer is greater than or equal to 50nm, that is, the physical thickness of the first high refractive index layer minus the physical thickness of the first low refractive index layer is ≥50nm, preferably ≥80nm, more preferably ≥100nm. The difference between the physical thickness of the second high refractive index layer and the physical thickness of the second low refractive index layer is greater than or equal to 30nm, that is, the physical thickness of the second high refractive index layer minus the physical thickness of the second low refractive index layer is ≥30nm, preferably ≥40nm, more preferably ≥45nm.

[0050] Specifically, the material of the first high refractive index layer and the second high refractive index layer is selected from the oxide, nitride or oxynitride of at least one element among Zn, Sn, Ti, Nb, Zr, Ni, In, Al, Ce, W, Mo, Sb, Bi, Si, Hf, Ta, Y, Ce, and La; the material of the first low refractive index layer and the second low refractive index layer is selected from the oxide, oxynitride or fluoride of at least one element among Si, Al, Mg, Ce, La, Y, and Ba.

[0051] In the present invention, the thermal insulation layer 4 comprises at least two metallic silver layers, silver alloy layers, or transparent conductive oxide layers. These metallic silver layers, silver alloy layers, or transparent conductive oxide layers have excellent infrared reflectivity, thereby reducing the total solar energy transmittance of the laminated insulating glass. The silver alloy layer is made of at least one selected from silver-copper alloy, silver-aluminum alloy, silver-indium alloy, silver-gold alloy, silver-platinum-gold alloy, silver-nickel alloy, silver-chromium alloy, silver-tin alloy, silver-titanium alloy, silver-zirconium alloy, silver-molybdenum alloy, silver-tungsten alloy, silver-manganese alloy, and silver-magnesium alloy. The silver content of the silver alloy layer is preferably greater than or equal to 95%, and more preferably greater than or equal to 98%. The transparent conductive oxide layer (TCO layer) is made of at least one selected from tin-doped indium oxide (ITO), fluorine-doped tin oxide (FTO), antimony-doped tin oxide (ATO), aluminum-doped zinc oxide (AZO), indium-doped zinc oxide (IZO), and gallium-doped zinc oxide (GZO). In order to enable the thermal insulation layer 4 to withstand the hot bending forming process of at least 550°C in automotive glass processing and to adjust the optical properties, mechanical properties, etc. of the thermal insulation layer 4, the thermal insulation layer 4 also includes other dielectric layers, such as ZnSnOx, ZnO, SiNx, TiOx, SiOx, ZrOx, NiCr, etc.

[0052] The outer glass panel 1 and / or the inner glass panel 2 are ultra-clear glass (also known as ultra-white glass), with a total iron content of less than or equal to 0.015% by mass and a visible light transmittance of greater than or equal to 91%. Preferably, the total iron content of the ultra-clear glass is less than or equal to 0.01%, less than or equal to 0.005%, or less than or equal to 0.001% by mass. The outer glass panel 1 and the inner glass panel 2 may even be substantially free of iron oxide (Fe2O3). For example, the outer glass panel 211 and the inner glass panel 212 may be soda-lime-silica ultra-clear glass, borosilicate glass, or high-aluminum glass.

[0053] After the infrared anti-reflection layer is deposited on the surface of the ultra-transparent glass by a magnetron sputtering process, the ultra-transparent glass with the infrared anti-reflection layer has a single visible light transmittance TL10 greater than or equal to 90%, and the ultra-transparent glass with the infrared anti-reflection layer has a first near-infrared transmittance Tp1 greater than or equal to 85% for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73°. Preferably, the first near-infrared transmittance Tp1 of the ultra-transparent glass with the infrared anti-reflection layer for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 55°-70° is greater than its single visible light transmittance TL10. Preferably, the first near-infrared transmittance Tp1 of the ultra-transparent glass with the infrared anti-reflection layer for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73° has a maximum value Tp1max and a minimum value Tp1min, and the difference between the maximum value Tp1max and the minimum value Tp1min is less than 10%.

[0054] The thermoplastic interlayer 3 is sandwiched between the outer glass pane 1 and the inner glass pane 2 to bond them together to form a laminated glass structure. Materials such as polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyethylene terephthalate (PET), polyurethane (PU), and ionomeric polymer film (SGP) can be used. The thermoplastic interlayer can be a single layer or comprise at least two layers. For example, one layer can have a higher plasticizer content to provide sound insulation, or one layer can be wedge-shaped to enable a head-up display (HUD) function.

[0055] In order to meet the national standard requirement that the visible light transmittance of automotive glass be greater than or equal to 70% and to ensure that no reflection is generated on the interior of the vehicle, it is preferred that the first visible light transmittance TL1 of the laminated insulating glass be greater than or equal to 85%, the second visible light transmittance TL2 be greater than or equal to 70%, and the fourth surface visible light reflectance RL4 be less than or equal to 10%. It is more preferred that the fourth surface visible light reflectance RL4 be less than or equal to 9%, or even less than or equal to 8%.

[0056] In order to make the laminated insulating glass have excellent thermal insulation performance and significantly improve the thermal comfort in the vehicle, the total solar transmittance Tts of the laminated insulating glass is preferably less than or equal to 50%, more preferably less than or equal to 40%.

[0057] In order to meet the use requirements of sensors such as lidar with a wavelength of 905nm P-polarized light and ensure the accuracy and efficiency of the sensor's large field of view detection, it is preferred that the second near-infrared transmittance Tp2 of the laminated insulating glass for P-polarized light with a wavelength of 905nm incident at an incident angle of 50°-73° is greater than or equal to 80%, and the second near-infrared transmittance Tp2 of the laminated insulating glass for P-polarized light with a wavelength of 905nm incident at an incident angle of 55°-65° is greater than or equal to 90%.

[0058] In order to make the laminated insulating glass have a good appearance color, it is preferred that the a value of the first surface reflection color Lab of the laminated insulating glass is -5 to 2, and the b value is -12 to 0.

[0059] The present invention further provides a vehicle comprising a sensor and the laminated insulating glass. For example, the laminated insulating glass can serve as a front windshield, etc. The sensor is mounted inside the vehicle. The sensor transmits and / or receives a detection signal that passes through the film removal area. The detection signal has a wavelength of 905 nm. Preferably, the detection signal enters the film removal area at an angle of incidence of 50° to 73° and comprises at least 80% P-polarized light.

[0060] The laminated insulating glass of the present invention enables automotive glass to meet the communication needs of highly sensitive communication sensors such as laser radars and infrared cameras, while also meeting the insulation requirements. This ensures that the total solar energy transmittance of the laminated insulating glass does not exceed 50%. Furthermore, the fourth surface has a low visible light reflectivity, further reducing the impact of glare on the driver when used as vehicle glass. Simultaneously, the attenuation of the laser radar or infrared camera signal through the laminated insulating glass is no more than 3dB, ensuring the normal operation of the laser radar or infrared camera. While improving the accuracy of the laser radar or infrared camera, it can significantly reduce air conditioning energy consumption and improve driver and passenger comfort. Furthermore, the laminated insulating glass of the present invention utilizes a full-surface coating process and a partial de-coating process for the insulation layer, resulting in a simple process and excellent consistency in the overall appearance of the film layer.

[0087]

[0088]

[0089] As shown in Tables 1 and 2, Comparative Example 1, which utilizes a single piece of ultra-clear glass without an infrared anti-reflection layer, exhibits a visible light transmittance exceeding 91%. However, the transmittance for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73° drops sharply from over 95% to below 85%. In particular, the first near-infrared transmittance Tp1 of Comparative Example 1 for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 70° is less than the single piece visible light transmittance TL10. Furthermore, the first near-infrared transmittance Tp1 of Comparative Example 1 for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73° has a maximum value Tp1max and a minimum value Tp1min, with the difference between the maximum value Tp1max and the minimum value Tp1min being greater than 10%.

[0090] Comparative Examples 2 and 4 are both ultra-transparent glasses with a four-layer infrared transmittance-enhancing layer. Their transmittance for P-polarized light with a wavelength of 905nm incident at an incident angle of 50°-73° is maintained above 85%, but their visible light transmittance drops sharply to below 90%, and even drops to below 85%.

[0091] Comparative Example 3 is an ultra-transparent glass with a six-layer infrared anti-reflection layer. The transmittance of P-polarized light with a wavelength of 905nm incident at an incident angle of 50°-73° is maintained above 85%, but its visible light transmittance drops sharply to below 90%. Moreover, the six-layer infrared anti-reflection layer has a more complicated manufacturing process and higher manufacturing cost than the four-layer infrared anti-reflection layer.

[0092] Comparative Example 5 is an ultra-transparent glass with a four-layer infrared transmission-enhancing layer. Its visible light transmittance exceeds 90%, but its transmittance for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73° drops sharply from over 95% to below 85%. In particular, the first near-infrared transmittance Tp1 of Comparative Example 5 for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 70° is less than the single-piece visible light transmittance TL10. Furthermore, the first near-infrared transmittance Tp1 of Comparative Example 5 for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73° has a maximum value Tp1max and a minimum value Tp1min, with the difference between the maximum value Tp1max and the minimum value Tp1min being greater than 10%.

[0093] Compared to Comparative Examples 1-5, the ultra-clear glass provided in Examples 1-3, which has a four-layer infrared anti-reflection layer, exhibits a single-piece visible light transmittance TL10 greater than 90%, and a first near-infrared transmittance Tp1 greater than 85% for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73°. Furthermore, the ultra-clear glass provided in Examples 1-3, which has a four-layer infrared anti-reflection layer, exhibits a first near-infrared transmittance Tp1 greater than its visible light transmittance TL10 for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 55°-70°. The ultra-transparent glass provided in Examples 1-3 and having a four-layer structure of infrared transmittance-enhancing layers has a maximum value Tp1max and a minimum value Tp1min for the first near-infrared transmittance Tp1 of P-polarized light with a wavelength of 905 nm incident at an incident angle of 50°-73°, and the difference between the maximum value Tp1max and the minimum value Tp1min is less than 10%, that is, Tp1max-Tp1min is less than 10%, thereby ensuring that the first near-infrared transmittance Tp1 of P-polarized light with a wavelength of 905 nm incident at different incident angles fluctuates less, thereby improving the stability and quality of acquiring point cloud data when used in conjunction with a lidar.

[0095] Comparative Example 6:

[0129]

[0131] Table 4: Test results of Comparative Examples 8-9 and Examples 7-9

[0132]

[0133] As can be seen from Tables 3 and 4, Comparative Example 6 uses the ultra-transparent glass with an infrared anti-reflection layer of Comparative Example 2 as the inner glass panel. Its second visible light transmittance TL2 is less than 70%, and its fourth surface visible light reflectance RL4 is greater than 10%. This fails to meet the national standard requirement for a visible light transmittance of greater than or equal to 70% for automotive glass. In addition, the high visible light reflectance inside the vehicle easily produces reflections, which interferes with driving safety.

[0134] Comparative Example 7 uses the ultra-transparent glass with an infrared anti-reflection layer of Comparative Example 3 as the inner glass plate. The visible light reflectivity RL4 of its fourth surface is greater than 10%. There is a problem that the visible light reflectivity in the car is too high and reflections are easily generated, which interferes with driving safety.

[0135] Comparative Example 8 uses the ultra-transparent glass with an infrared transmittance-enhancing layer of Comparative Example 4 as the inner glass panel. Its second visible light transmittance TL2 is less than 70%, and its fourth surface visible light reflectance RL4 is greater than 10%. These characteristics fail to meet the national standard requirement for a visible light transmittance of 70% or greater for automotive glass. Furthermore, the high visible light reflectance inside the vehicle easily produces reflections, interfering with driving safety. Furthermore, the b value of the first surface reflection color Lab of Comparative Example 8 is greater than 2, resulting in a yellowish color cast on the laminated insulating glass of Comparative Example 8 when viewed from outside the vehicle, making it difficult to meet the requirements for a good appearance color.

[0136] Comparative Example 9 uses the ultra-transparent glass with an infrared anti-reflection layer of Comparative Example 5 as the inner glass panel. The visible light reflectivity RL4 of its fourth surface is greater than 10%, which leads to the problem that the visible light reflectivity inside the vehicle is too high and easily produces reflections, which interferes with driving safety. In addition, the a value and b value of the first surface reflection color Lab of Comparative Example 9 are greater than 2, and even the a value is greater than 10. As a result, when the laminated insulating glass of Comparative Example 9 is observed from outside the vehicle, the color is seriously reddish and yellowish, making it difficult to meet the requirements of good appearance color.

[0137] Compared to Comparative Examples 6-9, the laminated insulating glass provided in Examples 4-9 achieves a first visible light transmittance TL1 greater than or equal to 85%, a second visible light transmittance TL2 greater than or equal to 70%, and a fourth surface visible light reflectance RL4 less than or equal to 10%. This not only meets the national standard requirement for automotive glass with a visible light transmittance of greater than or equal to 70%, but also ensures that no reflections are generated inside the vehicle. The laminated insulating glass provided in Examples 4-9 also achieves a total solar transmittance Tts less than or equal to 50%, or even less than or equal to 40%, demonstrating excellent thermal insulation performance and significantly improving thermal comfort within the vehicle. The laminated insulating glass provided in Example 4-9 can also achieve a second near-infrared transmittance Tp2 of greater than or equal to 80% for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 50°-73°, and even achieve a second near-infrared transmittance Tp2 of greater than or equal to 90% for P-polarized light with a wavelength of 905 nm incident at an angle of incidence of 55°-65°. This meets the requirements for sensors such as lidar that use P-polarized light with a wavelength of 905 nm, ensuring the accuracy and efficiency of the sensor's wide field of view detection. The laminated insulating glass provided in Example 4-9 can also achieve a first surface reflected color Lab with an a value of -5 to 2 and a b value of -12 to 0, resulting in a good appearance.
