Photo-curing 3D printing preparation method of black corundum-based TPMS heat absorption ceramic
The invention relates to the technical field of ceramic 3D printing, in particular to a black corundum-based TPMS heat absorption ceramic photocuring 3D printing preparation method which comprises the following steps: (1) dissolving black metal colorant ceramic powder and aluminum oxide ceramic powder in an aqueous solution containing fatty acid salt to obtain black metal ceramic powder coated with the aluminum oxide powder on the surface; (2) uniformly mixing the black metal ceramic powder coated with the aluminum oxide powder on the surface, aluminum oxide ceramic powder, light-cured resin, a dispersing agent and a photoinitiator to obtain composite ceramic slurry; and (3) designing a TPMS lattice structure from the composite ceramic slurry by utilizing 3D printing, and carrying out photocuring 3D printing, thermal degreasing and sintering to prepare the black corundum-based TPMS heat-absorbing ceramic. According to the scheme, the oxide-based heat-absorbing ceramic for solar thermal power generation is prepared by utilizing a photocuring 3D printing technology, and the technical problem that the oxide-based heat-absorbing ceramic for solar thermal power generation with complex shape and high absorptivity is difficult to prepare by a traditional forming method is solved.
