Daytime radiation refrigeration block material with spectral selectivity as well as preparation method and application of daytime radiation refrigeration block material
The invention discloses a daytime radiation refrigeration block material with spectral selectivity and a preparation method and application thereof.The daytime radiation refrigeration block material is composed of a protection layer and a radiation refrigeration functional layer, and the surface of the radiation refrigeration functional layer is coated with the protection layer; the protective layer is prepared from a macromolecular film-forming substance; the radiation refrigeration functional layer is prepared from an oxide block material, the oxide block material is prepared from an inorganic oxide, and the inorganic oxide is at least one of magnesium oxide, barium oxide, zirconium oxide, cerium oxide, zinc oxide, aluminum oxide and lithium fluoride. The reflectivity of the daytime radiation refrigeration block material exceeds 95% in the solar spectrum band, the emissivity is high in the 8-13 [mu] m atmosphere window band, and the reflectivity is high in the 2.5-8 [mu] m band and the 13-25 [mu] m band. Therefore, the daytime radiation refrigeration material absorbs less solar radiation and atmospheric reverse radiation, and a better refrigeration effect can be realized.
本发明公开一种具有光谱选择性的日间辐射制冷块体材料及其制备方法、应用，该日间辐射制冷块体材料，由保护层和辐射制冷功能层组成，保护层涂覆在所述辐射制冷功能层表面；保护层由高分子类成膜物质制备而成；辐射制冷功能层由氧化物块体材料制备而成，氧化物块体材料由无机氧化物制备而成，无机氧化物为氧化镁、氧化钡、氧化锆、氧化铈、氧化锌、氧化铝和氟化锂中的至少一种。本发明的日间辐射制冷块体材料在太阳光谱波段反射率超过95％，在8～13μm大气窗口波段高发射率，在2.5～8μm和13～25μm波段反射率较高。因此，本发明的日间辐射制冷材料对太阳辐射、大气逆辐射的吸收较少，可实现较好的制冷效果。
