SILVER PRODUCT WITH HYBRID ENERGY-SAVING COATING ON GLASS SUBSTRATE Russian patent published in 2018 - IPC C03C17/36 

Abstract RU 2642751 C1

FIELD: chemistry.

SUBSTANCE: coating comprises the first layer of titanium dioxide of TiO2 adjacent to the surface of the glass substrate, the first contact layer of Zn-Al-O, the first silver layer of Ag, reflecting infrared radiation, the first covering layer of Zn-Al-O, an intermediate layer of Zn-Sn-O, the second contact layer of Zn-Al-O, the second silver layer of Ag, the second covering layer of Zn-Al-O, an outer protective layer of Zn-Sn-O. The thickness of the intermediate layer of Zn-Sn-O is from 85 nm to 98 nm, and the thickness of the TiO2 layer is from 20 nm to 24 nm. The ratio of the thickness of the layer of TiO2 to the thickness of the outer protective layer is in the range of 0.56 to 0.75. The aggregate thickness of two silver layers of Ag is such that the resultant surface resistivity of the product with a hybrid energy-saving coating does not exceed 4 Ohm/sq. The ratio of the thickness of the first silver layer of Ag to the thickness of the second silver layer of Ag is 0.17 to 0.28. 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 0.672. The product has a silver colour.

EFFECT: reduction of heat losses during a cold weather, increase of translucence, decrease in the level of transmission of ultraviolet radiation.
