SUN-SCREENING LAYERED STRUCTURE Russian patent published in 2010 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: present invention relates to a sun-screening multi-layer structure formed on a sheet of glass material. The structure has at least one functional layer consisting of silver-based material which reflects infrared radiation and at least two dielectric coatings, where each functional layer is surrounded by dielectric coatings. When depositing common calcosodic float glass with thickness of 6 mm onto the sheet, said layered structure has solar factor SF less than 45% and light transmission LT less than 70%. According to the invention, the layered structure essentially consists of metallic absorbing material based on the following elements: Pd, Pt, Au, Ir, Rh, Ru, Os, Co, Ni, Cu, Cr, La, Ce, Pr, Nd, W, SI, Zn, Mo, Mn, Ti, V, Nb, Hf, Ta and alloys thereof, lying in the immediate vicinity of the functional layer or is included in that functional layer.

EFFECT: formation of selective glasing with high solar factor and good appearance and, particularly, such glasing which can undergo high-temperature quenching and/or flexure.
