SOLAR HEAT INFLUX CONTROLLING COATING WITH IMPROVED CONTROL CHARACTERISTICS Russian patent published in 2020 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: invention relates to a coating for window glazing. Disclosed is a coating which regulates solar heat influx, comprising: a first layer with a controlled phase; first metal functional layer arranged above first layer with controlled phase; a first undercoating layer on top of the first metal functional layer; second layer with controlled phase, located above first metal functional layer; second metal functional layer located on top of second layer with controlled phase; a second undercoating layer on top of the second metal functional layer; third layer with controlled phase located on top of second metal functional layer; third metal functional layer located on top of third layer with controlled phase; third base layer over third metal functional layer; and fourth layer with controlled phase, located above third metallic functional layer. Second metal functional layer comprises a continuous metal film, reflecting infrared radiation, and at least one absorbent film containing nickel and chromium alloy. A third metal functional layer contains at least one absorbent film containing copper above third layer with controlled phase and at least one film, reflecting infrared radiation and containing silver on top of at least one absorbing film.

EFFECT: technical result is reduced coefficient of solar heat gain and increased ratio of light flux to solar heat input.
