Daytime radiation refrigeration material and preparation method thereof
The invention discloses a daytime radiation refrigeration material which is formed by sintering raw materials, and the raw materials comprise at least one kind of inorganic particles with the size ranging from 0.1 micrometer to 100 micrometers in one or more directions, wherein the mass percent of the inorganic particles in the raw materials is not less than 50%. The invention also discloses a method for preparing the daytime radiation refrigeration material. The daytime radiation refrigeration material has very high sunlight reflectivity and infrared band emissivity in an atmospheric window, and can realize an efficient radiation refrigeration effect; meanwhile, the daytime radiation refrigeration material is a full-inorganic block material, has good mechanical strength and durability and can be applied to building materials such as tiles and ceramic tiles.
本发明公开了一种日间辐射制冷材料，由原料烧结而成，该原料包括至少一种在一个或多个方向上的尺寸介于0.1～100μm之间的无机颗粒；其中，无机颗粒在所述原料中的质量百分比不低于50％。本发明还公开了一种用于制备前述日间辐射制冷材料的方法。本发明提供的日间辐射制冷材料具有很高的太阳光反射率和大气窗口中红外波段发射率，能够实现高效的辐射制冷效果；同时该日间辐射制冷材料为全无机块体材料具有良好的机械强度和耐久性，能够应用于瓦片和瓷砖等建筑材料中。
