Black ceramic powder photocuring 3D printing slurry and preparation method thereof
The invention discloses black ceramic powder 3D printing photocuring slurry and a preparation method thereof. The photocuring slurry comprises the following raw materials in parts by weight: 100 parts of black ceramic powder, 70-100 parts of auxiliary printing ceramic powder, 2-5 parts of photosensitive resin, 1-2 parts of a photoinitiator, 1-2 parts of a defoaming agent, 1-2 parts of a flatting agent, 1-2 parts of a dispersing agent and 164-294 parts of a solvent. According to the preparation method, the light-colored ceramic powder easy to cure is added into the black ceramic powder difficult to photocure and mixed with the photoinitiator, the dispersing agent and other auxiliaries to prepare the slurry, the flowability of the slurry can be improved to a great extent by adding the light-colored ceramic powder easy to photocure, and the curing capacity of the slurry to ultraviolet light is improved; the single-layer curing thickness can reach 54 microns or above, and forming of photocuring printing is facilitated.
本发明公开了一种黑色系陶瓷粉体3D打印光固化浆料及制备方法，其中光固化浆料包括以下重量份数的各原料：黑色系陶瓷粉末100份、辅助打印陶瓷粉末70‑100份、光敏树脂2‑5份、光引发剂1‑2份、消泡剂1‑2份、流平剂1‑2份和分散剂1‑2份，还包括溶剂164‑294份。本发明制备方法通过将难以光固化的黑色系陶瓷粉末中添加易于固化的浅色陶瓷粉末，将其与光引发剂、分散剂和其他助剂混合配置成浆料，易于光固化陶瓷粉末的添加可以很大程度上改善其流动性、提高浆料对于紫外光的固化能力，使得单层固化厚度能达到54μm以上，有利于光固化打印的成型。
