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

FIELD: manufacturing technology.

SUBSTANCE: invention relates to products of bronze color with a hybrid energy-saving coating. Multilayer coating comprises layers in the following order from the surface of the glass substrate: the first layer of titanium dioxide TiO2; the first contact layer of Zn-Al-O; the first layer of silver Ag, reflecting infrared radiation; the first cover layer of Zn-Al-O; an intermediate layer of Zn-Sn-O; a second contact layer of Zn-Al-O; the second layer of silver Ag, reflecting infrared radiation; Zn-Al-O layer, which is the second cover layer; outer layer of Zn-Sn-O to protect the entire previously listed layer structure. Thickness of the intermediate layer Zn-Sn-O is from 50 to 75 nm, the thickness of the TiO2 layer is from 25 to 37 nm. Ratio of the thickness of the TiO2 layer to the thickness of the outer protective layer Zn-Sn-O is in the range from 0.6 to 1.3. Cumulative thickness of the two infrared-reflecting layers containing silver Ag is such that the resulting surface ohmic resistance of the product with the hybrid energy-saving coating does not exceed 4 Ω/□(square). Ratio of the thickness of the first layer of silver Ag to the thickness of the second layer of silver Ag is from 1.1 to 1.4. Ratio of the thickness of the first Zn-Al-O covering layer to the thickness of the first Zn-Al-O contact layer and the ratio of the thickness of the second Zn-Al-O coating layer to the thickness of the second Zn-Al-O contact layer are equal to and not more than 0.585.

EFFECT: reduction in the coefficient of direct transmission of solar radiation, a decrease in radiative heat losses during cold weather, increased light transparency, reduced transmission of ultraviolet radiation of near UV part of the spectrum.
