CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. § 371 of International Application No. PCT/KR2017/009513, filed on Aug. 30, 2017, which claims the benefit of priority to Korean Application No. 10-2016-0112061, filed on Aug. 31, 2016, the content both of which is are incorporated herein by reference in its their entirety.

TECHNICAL FIELD

This disclosure relates to glass laminates, and more particularly to laminates including a glass sheet laminated to a non-glass substrate and that have improved flatness after exposure to temperature and/or humidity changes.

BACKGROUND ART

Glass laminates generally include a glass sheet laminated to a non-glass substrate. Such glass laminates can be used as architectural panels that can be employed as wall panels, backsplashes, cabinet or furniture faces, appliance faces, or other architectural applications. The glass laminates can be exposed to relatively large changes in temperature and/or humidity (e.g., during formation, transportation, installation, and/or use), which can cause expansion or contraction of the non-glass substrate. Such expansion or contraction of the non-glass substrate can cause mechanical stress within the glass laminate, resulting in bowing, cracking, delamination, or other defects in the glass laminate.

DISCLOSURE OF INVENTION

Solution to Problem

Disclosed herein are glass laminates with improved flatness and methods for forming the same.

Disclosed herein is a glass laminate comprising a non-glass substrate comprising a first surface and a second surface opposite the first surface. A glass sheet is laminated to the first surface of the non-glass substrate. A barrier film is laminated to the second surface of the non-glass substrate and comprises a first surface adjacent to the non-glass substrate, a second surface opposite the first surface, and a thickness of at most about 0.5 mm. The second surface of the barrier film defines an outer surface of the glass laminate.

Disclosed herein is a glass laminate comprising a non-glass substrate comprising a first surface and a second surface opposite the first surface. A glass sheet is laminated to the first surface of the non-glass substrate. A multi-layer barrier film is laminated to the second surface of the non-glass substrate and comprises a metal layer and a polymer layer. An absolute value of a flatness of the glass laminate determined according to European Standard EN 438 after exposure to 23° C. and 90% relative humidity for 7 days is at most about 3 mm/m.

Disclosed herein is a method for forming a glass laminate. The method comprises laminating a glass sheet to a first surface of a non-glass substrate. A multi-layer barrier film is laminated to a second surface of the non-glass substrate and comprises a metal layer and a polymer layer.

It is to be understood that both the foregoing general description and the following detailed description are merely exemplary, and are intended to provide an overview or framework to understanding the nature and character of the claimed subject matter. The accompanying drawings are included to provide a further understanding, and are incorporated in and constitute a part of this specification.
