Abstract

A transparent laminated glass is described. The transparent laminated glass can comprise a transparent outer pane, at least one polymer layer, and a transparent inner pane. Uses of the transparent laminated glass are also described.

Claims (18)

1. A transparent laminated glass comprising:

i) a transparent outer pane with a thickness of 1.6 mm to 1.8 mm,

ii) at least one polymer layer with a thickness of 0.76 to 0.86 mm, and

iii) a transparent inner pane with a thickness of 1.2 mm to 1.4 mm,

wherein the at least one polymer layer contains ethylene vinyl acetates, plasticized polyvinyl butyrals, polyurethanes, polycarbonates, polyethylene terephthalates, ionomers, copolymers, and/or combinations thereof, and wherein a ratio of the thickness of the transparent outer pane to a sum of the thickness of the transparent outer pane and the transparent inner pane is from 0.552 to 0.571.

2. The transparent laminated glass according to claim 1 , wherein the transparent laminated glass is two-dimensionally and/or three-dimensionally bent in the longitudinal direction and/or the transverse direction.

3. The transparent laminated glass according to claim 1 , wherein the transparent outer pane is partially coated with an opaque layer on a side facing the at least one polymer layer.

4. The transparent laminated glass according to claim 1 , wherein edge tensile stress of the transparent outer pane is less than or equal to 7 MPa.

5. The transparent laminated glass according to claim 1 , wherein maximum value of optical distortion in the at least one polymer layer is less than or equal to 1 arc minute.

6. A method of using a transparent laminated glass comprising providing the transparent laminated glass according to claim 1 in a motor vehicle glazing.

7. A method for using a transparent laminated glass comprising providing the transparent laminated glass according to claim 1 in a motor vehicle glazing as a windshield.

8. The transparent laminated glass according to claim 1 , wherein the thickness of the transparent outer pane is from 1.70 mm to 1.80 mm.

9. The transparent laminated glass according to claim 3 , wherein the opaque layer is in the shape of a frame.

10. The transparent laminated glass according to claim 9 , wherein the opaque layer is in the shape of a frame with a width of 10 mm to 300 mm and a thickness of 1 μm to 500 μm.

11. The transparent laminated glass according to claim 1 , wherein the transparent inner pane or the transparent outer pane are completely or partially coated on a side facing the at least one polymer layer with at least one infrared radiation shielding layer, the at least one infrared radiation shielding layer having a thickness of 1 nm to 1000 nm, and

wherein the at least one infrared radiation shielding layer contains silver.

12. The transparent laminated glass according to claim 1 , wherein the at least one polymer layer has a thickness of 0.80 to 0.86 mm.

13. The transparent laminated glass according to claim 1 , wherein the at least one polymer layer contains a plurality of layers of polymers.
