Daytime passive radiation refrigeration ceramic with self-cleaning function and preparation method thereof
The invention belongs to the field of refrigeration materials, and particularly discloses daytime passive radiation refrigeration ceramic with a self-cleaning function and a preparation method thereof.The daytime passive radiation refrigeration ceramic comprises a substrate layer, the substrate layer is made of a porous composite ceramic material, and the pore structure of the substrate layer is composed of multi-aperture graded closed pores; the daytime radiation refrigeration ceramic can also comprise a protective layer. The preparation method comprises the following steps: adding a polymer solution into the metal oxide and the micron hollow glass beads to form pug; putting the pug into a mold; applying pressure to the pug in the mold to form a green body; the green body is dried; and sintering the dried green body to obtain the porous composite ceramic with the radiation refrigeration function. According to the invention, the porous composite ceramic is synthesized by using the multi-graded micron hollow glass beads, the porous composite ceramic is positioned below the protective layer, the porous composite ceramic has a multi-stage pore structure, and the pore size grading can be optimized, so that the porous composite ceramic has high daytime radiation refrigeration power and high mechanical strength at the same time.
