[ detailed description ] of the invention
Referring to fig. 1 to 7 of the specification, the invention relates to a preparation method of a triangular honeycomb porous ceramic material, which comprises the following process steps:
1) As shown in fig. 1, a two-dimensional model of a single-layer triangular honeycomb structure was designed.
As shown in fig. 2, a three-dimensional model is constructed in computer model design software according to a two-dimensional model, so as to obtain a single-layer triangular honeycomb structure (primary unit).
2) The three-layer primary unit is stacked to obtain a three-layer triangular honeycomb structure (secondary unit). Specifically, the three-layer single-layer triangular honeycomb structure (primary unit) is subjected to geometric transformation and then combined to obtain the three-layer triangular honeycomb structure (secondary unit). The geometric transformation includes translation, rotation in either direction, or any combination thereof. In this embodiment, the primary units of the second and third layers are rotated 60 ° and 120 ° with respect to the primary units of the first layer, respectively.
3) And stacking the secondary units to obtain a three-dimensional model of the tubular geometric body. Wherein the geometry includes, but is not limited to, prismatic, cylindrical, and cubic.
4) And (3) importing the designed tubular three-dimensional model data into a 3D printer, and printing the model by taking the ceramic slurry added with the pore-forming agent as a printing material. The 3D printer extrudes the slurry with high ceramic content from the nozzle through the material extrusion process, the viscosity of the ceramic slurry is reduced along with the shearing of the extrusion process in the extrusion process, when the slurry is extruded, the shearing stress on the material is reduced, the viscosity is increased, and the extruded slurry returns to the previous pasty consistency, so that self-support is realized.
Further, the pore-forming agent includes, but is not limited to, carbon powder, starch. Meanwhile, the porosity and the pore size of the model are adjusted by changing the volume fraction and the size of the pore-forming agent in the ceramic slurry; or, by controlling the volume fraction and the size of the pore-forming agent in the ceramic slurry in different printing time periods, different pore characteristics at different positions in the triangular honeycomb ceramic structure model are realized.
5) And (3) sintering the ceramic blank obtained in the step (4) in a high-temperature environment to enable abundant micropores to exist in the interior and the surface, and finally obtaining the tubular triangular honeycomb porous ceramic material.
Referring to fig. 4-6 of the drawings, it is clearly seen that the tubular triangular cellular porous ceramic material has regular triangular "frames" within it and that each layer of frames are inter-lapped to form a triangular honeycomb structure. The triangular honeycomb structure can improve the mechanical properties to a certain extent. When a crack is generated under load, a certain unit surface is broken, and in the crack conduction process, the structure can change the crack propagation direction, prolong the crack propagation path, realize crack redirection, show the mechanical characteristic of pseudo plasticity and solve the problem of high brittleness of the material.
Reference is made to fig. 7 of the accompanying specification, which shows the "pseudo-plastic" mechanical properties exhibited by triangular honeycomb structures. Wherein peaks and valleys in the stress-strain curve represent fractures of certain elementary surfaces, the overall trend of the stress-strain curve is similar to that of plastic materials, since the structure itself can guide crack propagation.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the scope of the present invention.
