Inorganic nanocomposite material for 3D (three-dimensional) printing and preparation method thereof

The invention discloses an inorganic nanocomposite material for 3D (three-dimensional) printing. The inorganic nanocomposite material contains the ingredients in percentage by weight: 75-85% of ceramic precursor powder, 5-10% of nanopowder reinforcing material, 2-5% of surfactant, 2-5% of organic solvent, 1-4% of inorganic binder and 5-10% of low-temperature curing agent, wherein the particle size of the nanopowder reinforcing material is 20-200nm. The surfactant is adopted to carry out disaggregation on nanopowder, so that the nanopowder has excellent dispersity; by adding the nanopowder into the ceramic precursor powder, the density and strength of ceramics can be improved, and the toughness of products is further improved; inorganic mixed powder, the inorganic binder and the low-temperature curing agent cooperate with one another, so that rapid binding can be achieved at low temperature; as a shaping raw material of 3D-printing rapid shaping machines, the inorganic nanocomposite material can be rapidly shaped effectively on 3D printers and can be applied to a variety of 3D printers of different models.
