Preparation method of 3D printing semi-opaque cracked green glaze ceramic product
The invention discloses a preparation method of a 3D printing semi-opaque cracked green glaze ceramic product. The preparation method comprises the following steps: (1) preparing 3D printing slurry, wherein the slurry comprises mud powder, paper pulp and water; the mud powder comprises the following components: Zijin soil, kaolin, ferric oxide and clinker; (2) preparing glazing slurry, wherein glaze components comprise yellow pond stone, quartz, calcined kaolin, calcite, talc and ferric oxide; (3) molding a 3D printing blank; (4) biscuit firing of the green body; (5) glaze dipping; and (6) firing. According to the Longquan celadon and the preparation method thereof, the blank components with the expansion coefficient similar to that of the glaze are selected, and the clinker with the specific components is added into the blank, so that the blank can be subjected to 3D printing forming through an LDM method under the condition that an organic binder is not added, the prepared ceramic product is good in blank-glaze binding property and good in glaze quality, and rapid and large-scale industrial production of the Longquan celadon can be achieved.
本发明公开了一种3D打印半乳浊开片青釉陶瓷制品的制备方法，步骤为：（1）制备3D打印浆料：浆料组分包括泥粉、纸浆和水；泥粉的组分包括紫金土，高岭土，氧化铁和熟料；（2）制备上釉浆料：釉料组分包括黄塘石、石英、煅烧高岭土、方解石、滑石、氧化铁；（3）3D打印坯体成型；（4）坯体素烧；（5）浸釉；（6）烧制。本发明选取与釉料膨胀系数相近的坯料组分，并在坯料中添加特定组分的熟料，使坯料可以在不添加有机粘结剂的情况下通过LDM法3D打印成型，且制成的陶瓷制品坯釉结合性好，釉面质量佳，可以实现龙泉青瓷的快速、大规模工业化生产。
