Purple sand ceramic slurry suitable for photocuring additive manufacturing and preparation method of purple sand ceramic slurry
The invention discloses a purple sand ceramic slurry suitable for photocuring additive manufacturing and a preparation method thereof, and the purple sand ceramic slurry comprises the following components in parts by weight: 65-85 parts of modified purple sand ceramic powder, 10-20 parts of a photocuring resin mixture, 1-5 parts of a photoinitiator and 2-10 parts of a dispersant, the light-cured resin mixture comprises an oligomer and a light-cured monomer, and the mass ratio of the oligomer to the light-cured monomer is 1: (1.5-2.5); the modified purple sand ceramic powder is of a core-shell structure with purple sand ceramic as a core and modified resin as a shell, the modified purple sand ceramic powder comprises purple sand ceramic powder and modified resin, and the mass percentage of the modified resin is 5-10 wt%. The modified purple sand ceramic powder with a core-shell structure is prepared by coating the surface of the purple sand ceramic powder with the modified resin, the compatibility of the ceramic powder and a light-cured resin mixture is increased through a similar compatibility principle, on the other hand, the space resistance of ceramic particles is increased, and the stability of ceramic slurry is improved; and by adjusting the mass ratio of the modified resin, the ceramic slurry with high solid content and low viscosity is prepared and has relatively good practicability.
本发明公开了一种适用于光固化增材制造的紫砂陶瓷浆料及其制备方法，所述紫砂陶瓷浆料按重量份计算包括改性紫砂陶瓷粉料65‑85份、光固化树脂混合物10‑20份、光引发剂1‑5份和分散剂2‑10份，所述光固化树脂混合物包括低聚物和光固化单体，且低聚物和光固化单体的质量比为1：1.5‑2.5；所述改性紫砂陶瓷粉料为以紫砂陶瓷为核且改性树脂为壳的核壳结构，所述改性紫砂陶瓷粉料包括紫砂陶瓷粉料和改性树脂，且改性树脂的质量百分比为5wt％‑10wt％。本发明通过在紫砂陶瓷粉料的表面覆有改性树脂，制备得到了核壳结构的改性紫砂陶瓷粉料，通过相似相容原理，增加了陶瓷粉料与光固化树脂混合物的相容性，另一方面增加了陶瓷颗粒的空间阻力，提高了陶瓷浆料的稳定性，并通过调整改性树脂的质量比，制备得到固含量高、粘度低的陶瓷浆料，具有较好的实用性。
