Abstract

The invention relates to a radiation refrigeration metal plate as well as a preparation method and application thereof. The radiation refrigeration metal plate comprises a metal substrate, a first bonding layer and a radiation refrigeration function layer which are sequentially arranged in a stacked mode; the radiation refrigeration function layer is laid on the surface of the metal substrate, thefirst bonding layer is arranged between the metal substrate and the radiation refrigeration function layer, and the elongation at break of the radiation refrigeration function layer is 1%-300%. The radiation refrigeration metal plate has enough ductility and can generate enough deformation to deal with bending of the radiation refrigeration function layer in the pressing process, so the radiationrefrigeration function layer cannot be damaged or broken, and therefore the structural integrity of the radiation refrigeration function layer and the radiation refrigeration effect of the metal substrate are guaranteed. When the radiation refrigeration metal plate is used, the indoor air temperature of a building is reduced by about 5-10 DEG C under the condition that energy is not consumed compared with the condition that the radiation refrigeration metal plate is not used.

Description

technical field [0001] The invention relates to the technical field of radiation refrigeration, in particular to a radiation refrigeration metal plate, its preparation method and application. Background technique [0002] The metal substrate is rolled and cold-bent into various wave-shaped profiled plates, which are suitable for industrial and civil buildings, warehouses, special buildings, and roofs, walls, and exterior wall decorations of long-span steel structure houses. It has the advantages of high strength, convenient and quick construction, earthquake resistance, fire prevention, and rain resistance. [0003] Setting the radiation cooling functional layer on the metal substrate can give the metal substrate the function of passive cooling. The radiation cooling functional layer has a high emissivity at a wavelength of 8 μm-13 μm, so heat can be emitted to outer space through the atmospheric window in the form of electromagnetic waves. In order to exert its cooling fun...
