HEATED GLAZING WITH THINNED OUTER GLASS SHEET AND WITH HEATING LAYER WITH FLOW SEPARATION LINES Russian patent published in 2020 - IPC C03C27/12 B32B17/10 B64C1/14 

FIELD: heating.

SUBSTANCE: invention relates to heated glazing with anti-icing function using a conductive layer intended for use in aircraft engineering. Multilayer glazing comprises the first structural layer connected to the first glass sheet with thickness of 0.5–1.5 mm through the first intermediate adhesive layer. First glass sheet forms first outer side of multilayer glazing facing outer atmosphere, wherein the side of the first glass sheet facing the first intermediate adhesive layer is coated with a first heating conductive layer with thickness of 2 angstroms to 500 nm. First heating conducting layer has flow separation lines with thickness of 0.05–0.2 mm, separated by gap of 8 to 20 mm, made by etching to direct current between two current supply strips arranged along two opposite edges of glazing. First structural layer comprises glass sheet with thickness of 4 to 10 mm or from polymer material with thickness of 5 to 20 mm, and the first intermediate adhesive layer contains a layer of polyvinyl butyral (PVB), polyurethane (PU) or polyethylene vinyl acetate (EVA) with thickness of 0.5 to 20 mm.

EFFECT: invention reduces the sufficient power of the heating glazing to prevent formation of frost on its entire surface.
