High-precision ceramic 3D printing paste and preparation method thereof
The invention discloses a high-precision ceramic 3D printing paste material, which is prepared from the following ingredients in parts by weight: 14 to 20 parts of photosensitive resin, 80 to 86 parts of Al2O3 powder, 0.4 to 0.86 part of a dispersing agent, 0.06 to 0.2 part of a photoinitiator, 0.05 to 0.2 part of a thickening agent and 0.2 to 2 parts of a flatting agent. The photosensitive resin is a mixed solution of a monofunctional resin monomer and a bifunctional resin monomer, and the mass ratio of the monofunctional resin monomer to the bifunctional resin monomer is (1-2): (8-9). According to the high-precision ceramic 3D printing paste material, the Al2O3 paste material with high solid content is prepared by controlling flocculation and dispersion degrees, the material is uniform and stable, and the leveling agent is added to accurately control the layer thickness, so that the size precision of a green body obtained through 3D printing is higher, and the precision of a finished product obtained through later sintering is correspondingly improved.
本发明公开了一种高精度陶瓷3D打印膏料，按重量份数，包括以下组分：光敏树脂14‑20份，Al2O3粉体80‑86份，分散剂0.4‑0.86份，光引发剂0.06‑0.2份，增稠剂0.05‑0.2份，流平剂0.2‑2份；所述光敏树脂为单官能团树脂单体和双官能团树脂单体的混合液，所述单官能团树脂单体和双官能团树脂单体的质量比为1‑2：8‑9。这种高精度陶瓷3D打印膏料，通过控制絮凝和分散程度制备高固含量的Al2O3膏料，材料均匀稳定，而且加入流平剂对层厚进行精确控制，使3D打印出来的生坯尺寸精度更高，后期烧结成成品之后的精度也就相应地获得提高。
