Description

Window glass and vehicle

Technical Field

The application relates to the technical field of glass products, in particular to window glass and a vehicle.

Background

At present, ceramic ink is printed on the edge of automobile glass to form a shielding layer, and the effect of the shielding layer mainly comprises two points, namely, 1, a sealing rubber strip formed by the ceramic ink and capable of covering the edge of the automobile glass by a black edge, and blocking direct irradiation of sunlight to the sealing rubber strip so as to prevent the sealing rubber strip from being damaged due to aging caused by direct irradiation of ultraviolet rays of the sunlight, 2, ensuring the overall attractive appearance of external observation, and shielding traces of the sealing rubber strip and various accessories on the inner surface of the automobile glass.

In the prior art, automotive glass is subjected to high-temperature heat treatment and bent in the production process. Since the ceramic ink is located on the surface of the glass and the thermal conductivity of the ceramic ink is greater than that of the glass, the ceramic ink generally reaches normal temperature in preference to the glass during cooling. When the ceramic ink reaches normal temperature and cures, the glass in contact with the ceramic ink remains above normal temperature. In the process of continuously cooling and forming the glass, the solidified ceramic ink can apply stress to the edge position of the glass, so that stress concentration is generated at the edge position of the formed glass, and the structural strength of the edge position of the glass is reduced. The edge position of the glass is easily broken when being impacted by external force.

Detailed Description

The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present application are included in the protection scope of the present application.

Currently, most of window glass is laminated glass. Ceramic ink is typically screen printed at the edges of the laminated glass to create a masking effect at the edges of the laminated glass. Since the screen-printed mold is usually flat, it is necessary to screen-print the edges of the individual glass plates when the individual glass plates are flat, so as to form a ceramic ink layer on the edges of the individual glass plates. Subsequently, the single glass sheet is subjected to a high-temperature heat treatment to bend the single glass sheet into a shape. And then bonding and connecting the plurality of single glass plates after bending and forming through the thermoplastic layer to form the laminated glass.

In the process of bending and forming a single glass plate, as the ceramic ink is positioned on the surface of the glass, the thermal conductivity of the ceramic ink is larger than that of the glass, the cooling speed of the ceramic ink is larger than that of the glass, and the ceramic ink usually reaches normal temperature in preference to the glass. When the ceramic ink reaches normal temperature and cures, the glass in contact with the ceramic ink remains above normal temperature. In the process of continuously cooling and forming the glass, the solidified ceramic ink can apply stress to the edge position of the single glass plate, so that stress concentration is generated at the edge position of the formed single glass plate, and the structural strength of the edge position of the single glass plate is reduced. The edge position of the single glass plate is easy to break when being impacted by external force. Thus, the edge position of the laminated glass assembled from the individual glass plates is easily broken when an external force is applied.

In view of this, the present application provides a window glass 100 that can ensure structural strength of the window glass 100, and that can improve safety performance of the vehicle 1000 by applying the window glass 100 of the present application to the vehicle 1000.

The acid etching process is to immerse glass in an acid solution to make the surface of the glass have frosted effect through the corrosion of acid. The polishing process is to mechanically polish the surface of the glass by using a polishing tool (such as a grinding wheel and a grinding wheel) so as to blur the surface of the glass. The sand blasting process is to blast sand particles onto the glass surface using a high pressure air stream, thereby sanding the glass surface. The film forming process is to coat a special semitransparent film or frosted film on the surface of glass to make the glass show frosted glass effect. It will be appreciated that to increase the haze of the fifth portion 12a of the second glass sheet 12, reference may also be made to the surface treatment of the third portion 11a of the first glass sheet 11 described above.

It is to be understood that in the present embodiment, by making the haze of at least one of the first portion 13a of the intermediate layer 13 and the third portion 11a of the first glass plate 11 be 10% or more, the first portion 13a of the intermediate layer 13 and the third portion 11a of the first glass plate 11 fully overlap the shielding region S1, and the second portion 13b of the intermediate layer 13 and the fourth portion 11b of the first glass plate 11 fully overlap the non-shielding region S2, it is possible to make the shielding region S1 of the window glass 100 have a high haze, that is, the haze HS1 of the shielding region S1 is 10% or more. The first glass plate 11 and the second glass plate 12 are bonded by the interlayer 13 after the first glass plate 11 and the second glass plate 12 are subjected to the bending molding process, so that the interlayer 13 does not need to be subjected to high-temperature heat treatment, the optical performance of the interlayer 13 is more stable, and the optical performance of the window glass 100 is more stable.

By making the haze of the third portion 11a of the first glass plate 11 greater than or equal to 10% on the basis of the haze of the first portion 13a of the intermediate layer 13 being greater than or equal to 10%, the haze of the shielding region S1 of the window glass 100 is further increased, and the shielding effect of the shielding region S1 of the window glass 100 is achieved. Therefore, ceramic ink does not need to be printed on the shielding area S1 of the window glass 100 to form a shielding effect, stress applied to the edge position of the window glass 100 in the curing process by the ceramic ink is avoided, the structural strength of the window glass 100 is ensured, the edge position of the window glass 100 is prevented from being easily broken when being impacted by external force, and the safety performance of the window glass 100 is ensured.

In the present application, the haze of at least one of the first portion 13a of the intermediate layer 13 and the third portion 11a of the first glass plate 11 is greater than or equal to 10%, so that the shielding region S1 of the window glass 100 has high haze, and the shielding effect of the shielding region S1 is further achieved, thereby replacing the scheme of providing ceramic ink in the shielding region S1, and ensuring the structural strength of the window glass 100. The shielding region S1 may be provided with no ink layer or may be provided with an ink layer. The proportion of the ink layer in the shielding region S1 to the range of the shielding region S1 is less than or equal to 10%. For example, an ink layer may be provided in the masking zone S1 to mark the window glass 100.

In this embodiment, the window glass 100 may further include the heat insulating layer 20 and the low-emissivity layer 30. The insulating layer 20 is used to adjust the insulating properties of the window glass 100. The low-emissivity layer 30 is used to adjust the emissivity of the glazing 100.

The heat insulating layer 20 and the low-emissivity layer 30 are respectively located on different surfaces of the laminated glass 10. Illustratively, as in FIG. 3, the insulating layer 20 is laminated to the second surface 112 of the first glass sheet 11. The low emissivity layer 30 is laminated to the fourth surface 122 of the second glass sheet 12. The insulating layer 20 completely covers the non-shielding region S2 in the thickness direction (Z-axis direction) of the window glass 100. The low-emissivity layer 30 completely covers the non-shielding region S2 in the thickness direction (Z-axis direction) of the window glass 100.

In other embodiments, the window glass 100 may not be provided with the insulating layer 20 or the low-emissivity layer 30.

The insulating layer 20 includes a functional metal layer and a plurality of dielectric layers. Along the thickness direction of the heat insulating layer 20, dielectric layers are laminated on opposite sides of the functional metal layer. The number of functional metal layers may be one or more. Both the functional metal layer and the dielectric layer may be deposited by chemical vapor deposition (Chemical Vapor Deposition, CVD) or physical vapor deposition (Physical Vapor Deposition, PVD). Illustratively, the functional metal layer and the dielectric layer are both deposited by magnetron sputtering.

The dielectric layer may be deposited by chemical vapor deposition (Chemical Vapor Deposition, CVD) or physical vapor deposition (Physical Vapor Deposition, PVD) methods. Illustratively, the dielectric layer is deposited by magnetron sputtering.

The material of the dielectric layer may be at least one selected from nitrides, oxides and oxynitrides of metals such as Zn, sn, ti, si, al, ni, cr, nb, mg, zr, ga, Y, in, sb, V, ta and alloys thereof.

Referring to fig. 4, the present application provides a second embodiment of a window glass 100. The distinguishing feature of this embodiment from the first embodiment described above is that the window glass 100 further includes a haze layer. By the haze layer having high haze, high haze of the shielding region S1 is achieved.

In this embodiment, the haze layer is a light modulation film 40. The haze of the light modulation film 40 can be greater than or equal to 10%. Types of dimming films 40 include, but are not limited to, polymer dispersed liquid crystals (Polymer Dispersed Liquid Crystal, PDLC), polymer network liquid crystals (Polymer Network Liquid Crystal, PNLC), guest-host liquid crystals (Guest/Host Liquid Crystal, GHLC), electrochromic (Electrochromic, EC), and the like. The haze of the dimming film 40 has a minimum value and a maximum value. By adjusting the energization voltage of the light modulation film 40, the haze of the light modulation film 40 can be changed. The haze of the light modulation film 40 increases from a minimum value when the light modulation film 40 is energized, the haze of the light modulation film 40 increases with an increase in voltage, the haze of the light modulation film 40 reaches a maximum value when the voltage increases to a critical value, the haze of the light modulation film 40 decreases to a minimum value when the light modulation film 40 is deenergized, or the haze of the light modulation film 40 decreases from a maximum value when the light modulation film 40 is energized, the haze of the light modulation film 40 decreases with an increase in voltage, the haze of the light modulation film 40 reaches a minimum value when the voltage increases to a critical value, and the haze of the light modulation film 40 increases to a maximum value when the light modulation film 40 is deenergized.

It should be noted that the number of the dimming films 40 may be one or more. The embodiment of the present application will be described with reference to only one of the light modulation films 40.

In this embodiment, the intermediate layer 13 has a multilayer structure. The intermediate layer 13 includes a plurality of adhesive layers 133 laminated in order. The thickness, material and structure of the adhesive layer 133 can be described with reference to the adhesive layer 133 in the first embodiment. And will not be described in detail herein.

In this embodiment, a plurality of adhesive layers 133 are laminated in this order along the thickness direction (Z-axis direction) of the window glass 100. The light control film 40 is sandwiched between any two adhesive layers 133 in the thickness direction of the window glass 100. The dimming film 40 completely covers the shielding region S1. It will be appreciated that the dimming film 40 may also cover at least part of the non-shielded region S2.

The number of adhesive layers 133 and the position of the light control film 40 shown in fig. 4 are only for illustration of the structure of the plurality of adhesive layers 133 and the light control film 40, but the number of adhesive layers 133 may be other, and the light control film 40 may be sandwiched between any two other adhesive layers 133, and the number of adhesive layers 133 and the position of the light control film 40 are not limited. In fig. 4, only the light modulation film 40 is illustrated as a case where the shielding region S1 and the non-shielding region S2 are completely covered, and a specific limitation of the coverage of the light modulation film 40 is not formed.

It is to be understood that in the present embodiment, by sandwiching the light control film 40 between any two of the adhesive layers 133 of the intermediate layer 13 and making the light control film 40 entirely cover the shielded region S1, by adjusting the voltage applied to the light control film 40, the haze of the light control film 40 can be adjusted so that the haze of the light control film 40 is 10% or more, and further the shielded region S1 of the window glass 100 can be made to have high haze, that is, the haze HS1 of the shielded region S1 is 10% or more. Therefore, ceramic ink does not need to be printed on the shielding area S1 of the window glass 100 to form a shielding effect, stress applied to the edge position of the window glass 100 in the curing process by the ceramic ink is avoided, the structural strength of the window glass 100 is ensured, the edge position of the window glass 100 is prevented from being easily broken when being impacted by external force, and the safety performance of the window glass 100 is ensured.

In addition, the dimming film 40 covers at least part of the non-shielding region S2, and by adjusting the haze of the dimming film 40, the haze of the non-shielding region S2 of the window glass 100 can also be adjusted, so that the window glass 100 can be suitable for different application scenarios.

The light modulation film 40 is sandwiched between the two adhesive layers 133 after the first glass plate 11 and the second glass plate 12 are subjected to the bending molding process, and thus, the light modulation film 40 does not need to be subjected to a high-temperature heat treatment, and the optical performance of the light modulation film 40 is more stable.

In the present application, the haze layer may be used alone, or the high haze may be provided in the masking region S1 of the window glass 100 by providing the haze layer together with the high haze in a part of the laminated glass 10.

Referring to fig. 5, the present application provides a third embodiment of a window glass 100. The distinguishing feature of this embodiment from the first embodiment described above is that the window glass 100 further includes a haze layer. By the haze layer having high haze, high haze of the shielding region S1 is achieved.

In this embodiment, the haze layer is a functional layer 50. The haze of the functional layer 50 is constant. The haze of the functional layer 50 is greater than or equal to 10%. The functional layer 50 may be a film layer having a function of heat insulation, low radiation, or the like, or may be a film layer having no function of heat insulation, low radiation, or the like. Illustratively, the functional layer 50 is a film layer having a heat insulating or low-emissivity function, and the functional layer 50 achieves a haze of more than or 10% and a heat insulating effect or low-emissivity effect by a film system structure.

The functional layer 50 may be deposited by chemical vapor deposition (Chemical Vapor Deposition, CVD) or physical vapor deposition (Physical Vapor Deposition, PVD).

In the present embodiment, at least one of the first surface 111, the second surface 112, the third surface 121, or the fourth surface 122 of the laminated glass 10 is provided with the functional layer 50. The functional layer 50 completely covers the shielding region S1. It will be appreciated that the functional layer 50 may also cover at least part of the non-shielded region S2.

In fig. 5, only the case where one functional layer 50 is provided on the fourth surface 122 of the laminated glass 10 and the functional layer 50 completely covers the shielded region S1 and the non-shielded region S2 is illustrated, and the position and coverage of the functional layer 50 are not particularly limited.

It is to be understood that in the present embodiment, by providing the functional layer 50 with the functional layer 50 entirely covering the shielded region S1, the haze of the functional layer 50 is 10% or more, the shielded region S1 of the window glass 100 can be made to have high haze, that is, the haze HS1 of the shielded region S1 is 10% or more. Therefore, ceramic ink does not need to be printed on the shielding area S1 of the window glass 100 to form a shielding effect, stress applied to the edge position of the window glass 100 in the curing process by the ceramic ink is avoided, the structural strength of the window glass 100 is ensured, the edge position of the window glass 100 is prevented from being easily broken when being impacted by external force, and the safety performance of the window glass 100 is ensured.

In addition, the functional layer 50 can also have a heat insulating or low-radiation effect, and can also realize a heat insulating or low-radiation effect of the shielding region S1 while realizing a high haze of the shielding region S1 of the window glass 100. Particularly when the functional layer 50 covers at least part of the non-shielded region S2, a thermal insulation or low radiation effect of the non-shielded region S2 can also be achieved.

Even if the functional layer 50 is thin, and the functional layer 50 is attached to the first glass plate 11 or the second glass plate 12 and is processed by a bending process along with the glass plates, the functional layer 50 is insufficient to apply stress to the edge positions of the glass plates, so that the structural strength of the edge positions of the glass plates is reduced.

As can be seen from table 1, the haze HS1 of the masked areas S1 of the window glasses 100 of examples 1 to 6 is all greater than 80%, and the visible light transmittance TL1 of the masked areas S1 is all less than 6%. Thus, the shielding region S1 of the window glass 100 of examples 1 to 6 can each have a good effect of blocking the transmission of visible light. Wherein, haze HS2 of non-shielded region S2 of window glass 100 of examples 1 and 3 is less than 2%, and visible light transmittance TL2 of non-shielded region S2 is greater than 77%. Thus, the non-shielded region S2 of the window glass 100 of examples 1 and 3 can be used as a window, and the window glass 100 of examples 1 and 3 is suitable for a windshield of the vehicle 1000. The haze HS2 of the non-shielded region S2 of the window glass 100 of examples 2 and examples 4 to 6 is less than 6%, and the visible light transmittance TL2 of the non-shielded region S2 is less than 17%. Thus, the non-shielded region S2 of examples 2 and examples 4 to 6 can function as a barrier to the line of sight, and the window glass 100 of examples 2 and examples 4 to 6 is suitable for a backlight or sunroof glass of the vehicle 1000. By making the haze of the first portion 13a of the intermediate layer 13 larger than 10%, the shielded region S1 of the window glass 100 can be made to have high haze. The shielding region S1 of the window glass 100 has a good shielding effect.

Further, the haze HS1 of the shielding regions S1 of the window glasses 100 of examples 7 to 12 is larger than 65%, and the visible light transmittance TL1 of the shielding regions S1 is smaller than 6%. Thus, the shielding region S1 of the window glass 100 of examples 7 to 12 can each exert a good effect of blocking the transmission of visible light. Wherein, haze HS2 of non-shielded regions S2 of window glass 100 of examples 7 and 9 is less than 2%, and visible light transmittance TL2 of non-shielded regions S2 is greater than 77%. Thus, the non-shielded region S2 of the window glass 100 of examples 7 and 9 can be used as a window, and the window glass 100 of examples 7 and 9 is suitable for a windshield of the vehicle 1000. The haze HS2 of the non-shielded regions S2 of the window glasses 100 of examples 8 and examples 10 to 12 is less than 6%, and the visible light transmittance TL2 of the non-shielded regions S2 is less than 17%. Thus, the non-shielded region S2 of examples 8 and examples 10 to 12 can function as a barrier to the line of sight, and the window glass 100 of examples 8 and examples 10 to 12 is suitable for a backlight or sunroof glass of the vehicle 1000. By making the haze of the first portion 11a of the first glass plate 11 larger than 10%, the shielded region S1 of the window glass 100 can be made to have high haze. The shielding region S1 of the window glass 100 has a good shielding effect.

Since the haze HS1 of the shielding region S1 of the window glass 100 of example 13 is 85% and the visible light transmittance TL1 of the shielding region S1 is 62%, the shielding region S1 of the window glass 100 of example 13 has high haze on the basis of ensuring a constant visible light transmittance, and can provide a good shielding effect. The haze HS2 of the non-shielded region S2 of the window glass 100 of example 13 is 1.2%, and the visible light transmittance TL2 of the non-shielded region S2 is 73.5%, and thus the non-shielded region S2 of the window glass 100 of example 13 can be used as a window, and the window glass 100 of example 13 is suitable for a windshield of the vehicle 1000.
