Estimating the term…
The complexity of modern automotive glazing has been increasing as the industry moves towards full autonomous vehicles and consumers demand increased levels of comfort, convenience, and safety. This is especially true of laminates where value added components can be embedded between the glass layers. However, many of the materials used in the manufacture of said laminates are sensitive to moisture. Thus, it is necessary to seal the edges of the laminate. A number of methods have been developed but all have drawbacks. The edge sealed laminate of the invention is produced by injecting the edge seal material, after the laminate has been processed in an autoclave, into a gap, left by a spacer. The resulting edge seal need only contact the interior glass surfaces.
A laminated glazing for a vehicle, the glazing comprising:
The laminated glazing of any of the preceding claims, wherein said at least one bonding interlayer is comprised of polyvinyl butyral.
The laminated glazing of any of the preceding claims, wherein the edge seal is substantially flush with the edge of the glazing.
The laminated glazing of any one of the preceding claims, wherein the edge seal is comprised of one of the following:
The laminated glazing of any one of the preceding claims, wherein the edge seal is comprised of one of the following dispensed polyisobutylene, and dispensed non-plasticized polyvinyl butyral.
The laminated glazing of any one of the preceding claims, wherein each moisture sensitive material of said at least one moisture sensitive material is selected from the following a lighting means, a touch sensor, a photovoltaic integrated cells, a heated circuit, an antenna, light scattering means for indirect illumination, an electrical conductor, electrical insulator, and a graphic.
The laminated glazing of any one of the preceding claims, wherein the at least one bonding interlayer comprises two bonding interlayers sandwiching the at least one moisture sensitive material comprising integrated photovoltaic cells and sealed by an edge seal comprised of polyisobutylene.
The laminated glazing of any of the preceding claims is a vehicle roof.
A vehicle comprising the laminated glazing of any of the preceding claims.
