Porous ceramic filter for precision casting based on 3D printing and preparation method of porous ceramic filter
The invention discloses a porous ceramic filter for precision casting based on 3D printing and a preparation method thereof.The porous ceramic filter for precision casting based on 3D printing is prepared from, by mass, 75%-85% of ceramic powder, 8%-15% of solvent, 3%-8% of binder, 0.5%-1% of dispersing agent, 0.5%-1% of thixotropic agent and 0.5%-1% of lubricating agent; wherein the ceramic powder has various particle sizes. According to the porous ceramic filter for precision casting based on 3D printing and the preparation method of the porous ceramic filter, the surface of a product prepared through the method is of a porous structure, and suspended inclusions with the size at the micron level in molten metal can be efficiently filtered out; in addition, a 3D printing forming method is adopted, the product quality is stable, and the structure is uniform and controllable. The ceramic filter combines the advantages of traditional foamed ceramic and 3D printing, has the characteristics of good filtering performance, uniform and controllable structure, stable quality, low cost and the like, and has wide application prospects and extremely high market competitiveness.
本发明公开了基于3D打印的精密铸造用多孔陶瓷过滤器及其制备方法，其中基于3D打印的精密铸造用多孔陶瓷过滤器，按照质量百分比计，包括：陶瓷粉体75‑85％、溶剂8‑15％、粘结剂3‑8％、分散剂0.5‑1％、触变剂0.5‑1％、润滑剂0.5‑1％；其中所述陶瓷粉体包括多种粒度。本发明提供的基于3D打印的精密铸造用多孔陶瓷过滤器及其制备方法，该方法制成的产品表面呈多孔结构，可以高效过滤熔融金属中尺寸在微米级别的悬浮夹杂物；另外采用3D打印的成型方法，产品质量稳定且结构均匀可控。本发明中的陶瓷过滤器结合了传统泡沫陶瓷和3D打印的优点，具有过滤性能好、结构均匀可控、质量稳定、成本低等特点，具有广阔的应用前景和极强的市场竞争力。
