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.

First claim

The invention claimed is:

1. A method to fabricate a transparent laminated glass for motor vehicle glazings as a windshield with high stone impact resistance, the method comprising bonding a transparent outer pane, made of silicate glass with a thickness of 1.6 mm to 1.8 mm, to at least one polymer layer with a thickness of 0.76 mm or 0.86 mm, and bonding a transparent inner pane, made of silicate glass with a thickness of 1.2 mm to 1.4 mm, to the at least one polymer layer, wherein the at least one polymer layer contains plasticized polyvinyl butyrals and the ratio of the thickness of the transparent outer pane to the sum of the thickness of the transparent outer pane and the transparent inner pane is from 0.552 to 0.571.

2. The method to fabricate a transparent laminated glass of claim 1 , wherein the thickness of the transparent outer pane is 1.70 mm to 1.80 mm.

3. The method to fabricate a transparent laminated glass of claim 1 , further comprising bending the transparent laminated glass two-dimensionally and/or three-dimensionally in a longitudinal direction and/or a transverse direction of the transparent laminated glass.

4. The method to fabricate a transparent laminated glass of claim 1 , further comprising completely or partially coating the transparent inner pane or the transparent outer pane on a side facing the at least one polymer layer with at least one infrared radiation shielding layer with a thickness of 1 nm to 1000 nm.

5. The method to fabricate a transparent laminated glass of claim 1 , further comprising coating the at least one polymer layer with a layer that absorbs or reflects infrared radiation.

6. The method to fabricate a transparent laminated glass of claim 1 , further comprising partially coating with an opaque layer the transparent outer pane on the side facing the at least one polymer layer, and wherein the transparent outer pane is in the shape of a frame with a width of 10 mm to 300 mm and the opaque layer has a thickness of 1 μm to 500 μm.
