Title:
ASYMMETRIC LAMINATED GLASS AND MANUFACTURING METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/027785
Kind Code:
A1
Abstract:
Asymmetric laminated glass and a manufacturing method therefor and a use thereof. The asymmetric laminated glass comprises outer panel glass and inner panel glass which are not formed simultaneously, and an intermediate layer disposed between the outer panel glass and the inner panel glass, wherein the thickness of the outer panel glass is greater than that of the inner panel glass; at least 90% of surface regions of a second surface of the outer panel glass and of a third surface of the inner panel glass are both curved surfaces having constant Gaussian curvature; the second surface of the outer panel glass has main curvature K2z and auxiliary curvature K2f in the region, and the third surface of the inner panel glass has main curvature K3z and auxiliary curvature K3f in the region; and the following relational expressions are satisfied: K2f>K3f and 0.7≤(K3z×K3f)/(K2z×K2f)≤1.3. According to the present invention, by means of a curvature matching design, the width of an edge optical distortion region of the asymmetric laminated glass is controlled within 50 mm, and the thermoforming manufacturing feasibility of thin inner panel glass can also be improved.
