Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to an ink, a shielding ink layer, a vehicle glass and a vehicle. BACKGROUND

[0002] With the development of intelligent networking of automobiles, automobiles often need LiDAR, infrared cameras and other devices to realize real-time perception of road conditions and other information. These intelligent devices are often installed together with the automobile glass assembly in the vehicle, which requires the corresponding window area of the automobile glass to have some optical gain or shielding function. In the industry, a functional patch (the patch has a functional film layer) is usually embedded in the window area of the automobile glass to achieve the functional requirements of the window area. However, the edges of the functional patch are conspicuous and can cause a double image illusion. In addition, the bonding of the functional patch and the automobile glass usually relies on an OCA adhesive layer, and the uneven edge thickness of the OCA adhesive layer can also cause light distortion, thereby affecting the accuracy of signal transmission and human eye observation.

[0003] To solve the above problems, the traditional scheme uses shielding ink to cover the bonding edge, which is a practical and low-cost method. However, the problem that follows is that the ink sintered is mainly inorganic matter composed of oxides, which cannot be bonded with the organic resin skeleton of the OCA adhesive layer through covalent bond, ionic bond, metal bond, etc., resulting in a small bonding force between the shielding ink layer and the OCA adhesive layer. SUMMARY

[0004] Based on this, the first aspect of the present application provides an ink, and the technical scheme is as follows:

[0005] An ink, comprising glass powder, inorganic pigment, ink solvent and auxiliary agent; the glass powder comprises Bi2O3, SiO2, Al2O3, ZnO and B2O3;

[0006] Among them, the mass fraction of Bi2O3 in the glass powder is 60-75 parts, and the Bi2O3 is a porous particle; the mass fraction of SiO2 in the glass powder is 5-15 parts; the mass fraction of Al2O3 in the glass powder is 5-15 parts; the mass fraction of ZnO in the glass powder is 3-12 parts; the mass fraction of B2O3 in the glass powder is 2-10 parts.

[0007] The second aspect of the present application provides a shielding ink layer, which is prepared by sintering the ink as described above.

[0008] The third aspect of the present application provides a vehicle glass, and the technical scheme is as follows:

[0009] A vehicle glass, comprising:

[0010] a glass substrate having a signal transmission region for optical signal transmission and a shielding region surrounding the signal transmission region;

[0011] a shielding ink layer as described above on the shielding region;

[0012] an organic bonding layer on the signal transmission region and extending to cover part of the shielding ink layer;

[0013] a functional patch on the organic bonding layer.

[0014] The fifth aspect of the present application provides a vehicle comprising a shielding ink layer as described above, or a vehicle glass as described above.

[0015] Compared with the conventional scheme, the present application has the following beneficial effects:

[0016] In the present application, the glass powder is mainly Bi2O3 in the form of porous particles. The ink under this formula can form a porous structure on the surface of the shielding ink layer after sintering. The glue of the organic bonding layer (such as OCA glue layer) can enter these pores, improving the adhesion between the shielding ink layer and the organic bonding layer, and being conducive to improving the service life of the functional patch.

On the glass substrate surrounded by the ring-shaped ink layer, coat OCA glue, and make the glue extend to cover part of the shielding ink layer, the covering area is annular, and the area is 2000mm 2 . Cure the OCA glue to form an OCA glue layer to obtain a sample.

[0098]

[0099] Comparative Examples 1 to 7

[0100] Step 1, prepare the glass powder of Comparative Examples 1 to 7 according to the raw materials and mass fractions shown in Table 4. Among them, in Comparative Example 1, Bi2O3 is ordinary solid Bi2O3, in Comparative Example 2, the porosity of Bi2O3 is 25%, in Comparative Example 3, the porosity of Bi2O3 is 55%, and in other comparative examples, the porosity of Bi2O3 is 40%.

[0108]

[0109] From the test results of the examples and comparative examples, the following conclusions can be drawn: 1. The adhesion is closely related to the surface porosity of the shielding ink layer. When the porosity is large or the porosity is small, the adhesion does not meet the requirements. It is verified by experiment that the surface porosity of the shielding ink layer is 20%~35%, and the adhesion meets the requirements; 2. Compared with the use of porous granular Bi2O3, it is difficult to form a shielding ink layer with a surface porosity of 20%~35% using solid Bi2O3, and it is difficult to improve the adhesion between the shielding ink layer and the organic adhesive layer. 3. The porosity of the porous granular Bi2O3 is too high or too low, which is not conducive to controlling the surface porosity of the shielding ink layer within the range of 20%~35%, and the improvement of the adhesion between the shielding ink layer and the organic adhesive layer is limited. Preferably, the porosity of Bi2O3 is 30%~50%. 4. Too high or too low sintering temperature is not conducive to controlling the surface porosity of the shielding ink layer within the range of 20%~35%, and the improvement of the adhesion between the shielding ink layer and the organic adhesive layer is limited. Preferably, the sintering temperature is 570℃~670℃. 5. The mass fraction of glass powder in the ink affects the mass fraction of Bi2O3 in the ink, and then affects the surface porosity of the shielding ink layer. Preferably, the mass fraction of glass powder in the ink is 40~60 parts.
