PRODUCT WITH HYBRID ENERGY-SAVING COATING ON GLASS SUBSTRATE Russian patent published in 2017 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: coating contains the following layers in the order of increasing the distance from the surface of the glass substrate: a layer of titanium dioxide TiO₂, a contact layer of zinc oxide alloyed with aluminium Zn-Al-O, a layer of silver Ag, a covering layer of zinc oxide alloyed with aluminium Zn-Al-O, an intermediate layer of tin oxide alloyed with zinc Zn-Sn-O, the second covering layer of zinc oxide alloyed with aluminium Zn-Al-O, a layer of silver Ag, the second covering layer of zinc oxide alloyed with aluminium Zn-Al-O, an outer layer of tin oxide alloyed with zinc Zn-Sn-O. The thickness of the intermediate layer is from 45 to 60 nm, the thickness of the layer of titanium dioxide TiO₂ - from 14 to 20 nm. The ratio of the thickness of the layer of titanium dioxide TiO₂ to the thickness of the external protective layer is from 0.4 to 0.6, the thickness of the first layer of silver Ag to the thickness of the second layer of silver Ag is from 0.8 to 1.1. The ratio of the thickness of the first covering layer to the thickness of the first contact layer and the ratio of the thickness of the second covering layer to the thickness of the second contact layer are equal to and not more than 0.375.

EFFECT: decreasing the radiative heat losses during cold weather, increasing the translucency in relation to wavelengths of visible part of solar electromagnetic spectrum, decreasing the level of direct transmission of ultraviolet radiation in the near long-wave UV part of the spectrum.
