Vehicle windshield with two-dimensional code and manufacturing process thereof
A vehicle windshield with a two-dimensional code includes a first glass, a second glass and an intermediate film provided between the first glass and the second glass. The first glass includes a first surface facing the exterior of a vehicle and a second surface adhered to the intermediate film, while the second glass includes a third surface adhered to the intermediate film and a fourth surface facing the interior of the vehicle. Black enamel paint is printed on the second surface and/or the fourth surface. The second surface or the fourth surface is provided with a two-dimensional code printed with enamel paint at a position corresponding to the black enamel paint. The two-dimensional code contains unique information of the glass and/or the vehicle.
1. A vehicle windshield with a two-dimensional code, the vehicle windshield comprising a first glass, a second glass and an intermediate film provided between the first glass and the second glass, wherein the first glass comprises a first surface facing the exterior of a vehicle and a second surface adhered to the intermediate film, while the second glass comprises a third surface adhered to the intermediate film and a fourth surface facing the interior of the vehicle; and
wherein black enamel paint is printed on the second surface and/or the fourth surface; the second surface or the fourth surface is provided with a two-dimensional code printed with enamel paint at a position corresponding to the black enamel paint; and the two-dimensional code contains unique information of the glass and/or the vehicle.
2. The vehicle windshield according to claim 1 , wherein the enamel paint comprises black enamel paint or silver paste.
3. The vehicle windshield according to claim 2 , wherein the two-dimensional codes printed in different vehicle windshields are different.
4. The vehicle windshield according to claim 1 , wherein the black enamel paint on the second surface and/or the fourth surface has different gloss from the enamel paint for printing the two-dimensional code.
5. The vehicle windshield according to claim 4 , wherein the two-dimensional codes printed in different vehicle windshields are different.
6. The vehicle windshield according to claim 1 , wherein the two-dimensional codes printed in different vehicle windshields are different.
7. A process for manufacturing a vehicle windshield with a two-dimensional code, the vehicle windshield comprising a first glass, a second glass and an intermediate film provided between the first glass and the second glass, wherein the first glass comprises a first surface facing the exterior of a vehicle and a second surface adhered to the intermediate film, while the second glass comprises a third surface adhered to the intermediate film and a fourth surface facing the interior of the vehicle, and wherein the process comprises the following steps:
a. providing a first glass and a second glass which are cut and shaped;
b. printing black enamel paint on the second surface and/or the fourth surface;
c. printing a two-dimensional code with enamel paint on the second surface or the fourth surface at a position corresponding to the black enamel paint, the two-dimensional code contains unique information of the glass and/or the vehicle;
d. molding the first glass and the second glass in a thermal-bending furnace; and
e. sandwiching an intermediate film between the first glass and the second glass which are thermal-bended and molded to obtain a finished product.
8. The process according to claim 7 , wherein the enamel paint comprises black enamel paint or silver paste.
9. The process according to claim 8 , wherein the black enamel paint on the second surface and/or the fourth surface has different gloss from the enamel paint for printing the two-dimensional code.
10. The process according to claim 9 , further comprising a step of pre-sintering the first glass and/or the second glass prior to the step d.
11. The process according to claim 8 , further comprising a step of pre-sintering the first glass and/or the second glass prior to the step d.
12. The process according to claim 7 , further comprising a step of pre-sintering the first glass and/or the second glass prior to the step d.
13. The process according to claim 12 , wherein, in step c, different two-dimensional codes are printed for different vehicle windshields.
