3D printing ceramic precursor composite material and preparation method thereof

The invention relates to the technical field of 3D printing ceramics, in particular to a 3D printing ceramic precursor composite material. The 3D printing ceramic precursor composite material is prepared from the following raw materials in parts by weight: 40 to 60 parts of clay, 20 to 30 parts of biomass superfine fibers, 80 to 120 parts of ceramic precursor polymer, 1 to 2 parts of photcatalyst,0.5 to 5 parts of fluorescent powder and 10 to 20 parts of photosensitive resin. The formula disclosed by the invention has the advantages of fewer non-target elements, pure product and high ceramicconversion rate; the 3D printing ceramic precursor composite material has a stable structure and can be used for the 3D printing molding; the 3D printing ceramic precursor composite material can be thermally decomposed into a stable target ceramic structure when in a needed atmosphere; by adding the photocatalyst, the ultraviolet curing molding speed can be favorably increased; and by adding the fluorescent powder, the fun
