Abstract
The present disclosure provides a radiative cooling functional coating material and application thereof. The radiative cooling functional coating material can be configured for manufacturing a radiative cooling functional layer. The radiative cooling functional layer can be configured for reflecting ultraviolet light and/or visible light and/or near-infrared light in sunlight and emitting heat through an atmospheric window in a form of infrared radiation. The radiative cooling functional coating material can include a granular filler and a radiative cooling functional resin, and the granular filler can be distributed in the radiative cooling functional resin.
Claims17
A selective radiative cooling coating layer comprising a radiative cooling functional layer manufactured by a radiative cooling functional coating material,
- the radiative cooling functional layer comprises a first radiative cooling functional layer and a second radiative cooling functional layer stacked in order,
- the first radiative cooling functional layer comprises the radiative cooling functional resin and a first granular filler distributed in the radiative cooling functional resin, and is configured for reflecting the visible light and the near-infrared light and emitting heat through the atmospheric window in the form of infrared radiation;
- the second radiative cooling functional layer comprises the radiative cooling functional resin and a second granular filler distributed in the radiative cooling functional resin, and is configured for reflecting the ultraviolet light and the visible light and emitting heat through the atmospheric window in the form of infrared radiation;
- the first granular filler is aluminum silicate, pearl powder, silicon dioxide, calcium carbonate, barium sulfate, talcum powder, titanium dioxide, zinc sulfide, ceramic powder, ceramic bead, glass bead, or a combination thereof,
- the second granular filler is aluminum oxide, zinc oxide, zirconium oxide, cerium oxide, lanthanum oxide, rhodium dioxide, magnesium oxide, or a combination thereof.
